Install Roundcube Webmail on CentOS 8/RHEL 8 with Apache/Nginx
Roundcube is a free open source, full-featured webmail client written in PHP. A webmail is a mail client in your browser, which means instead of reading and sending emails from a desktop mail client like Mozilla Thunderbird, you can access your email from a web browser. This tutorial is going to show you how to install Roundcube webmail on CentOS 8/RHEL 8 with Apache or Nginx web server.
Roundcube Features
Roundcube functionality includes:
- Address book
- Folder management
- Message searching
- Message filter
- Spell checking
- MIME support
- PGP encryption and signing
- Users are able to change their password in Roundcube.
Roundcube 1.4.2 Release
Roundcube 1.4.2 was released on January 2, 2020. This release features:
- A responsive skin called Elastic with full mobile device support
- Email Resent (Bounce) feature
- Improved Mailvelope integration
- Support for Redis and Memcached cache
- Support for SMTPUTF8 and GSSAPI
- Plus numerous improvements and bug fixes
Prerequisites
To follow this tutorial, it’s assumed that
- Postfix SMTP server and Dovecot IMAP server have been installed on your CentOS 8/RHEL 8 server
- You have already installed a LAMP stack or LEMP stack on CentOS 8/RHEL 8 server.
If not, please click the above links and follow the instructions to complete prerequisites. Now let’s proceed to install Roundcube.
Step 1: Download Roundcube Webmail on CentOS 8/RHEL 8
Log in to your CentOS/RHEL server via SSH, then run the following command to download the latest 1.4.9 stable version from Roundcube Github repository.
wget https://github.com/roundcube/roundcubemail/releases/download/1.4.9/roundcubemail-1.4.9-complete.tar.gz
Note: You can always use the above URL format to download Roundcube from command line. If a new version comes out, simply replace 1.4.9 with the new version number. You can check if there’s new release at Roundcube download page.
Extract the tarball, move the newly created folder to web root (/var/www/
) and rename it as roundcube
at the same time.
tar xvf roundcubemail-1.4.9-complete.tar.gz sudo mkdir /var/www/ sudo mv roundcubemail-1.4.9 /var/www/roundcube
Step 2: Install Dependencies
Roundcube requires the php-imap
module to create subfolders in mailboxes, but php-imap isn’t included in the default CentOS 8/RHEL 8 repository, so we need to use the Remi repo to install this PHP module.
Install the Remi Repo.
sudo dnf install -y https://rpms.remirepo.net/enterprise/remi-release-8.rpm
Then reset PHP module streams.
sudo dnf module reset php
Enable the php:remi-7.4
module stream.
sudo dnf module enable php:remi-7.4 -y
Then you can run the following command to install PHP modules required or recommended by Roundcube.
sudo dnf install php-ldap php-imagick php-common php-gd php-imap php-json php-curl php-zip php-xml php-mbstring php-bz2 php-intl php-gmp
Step 3: Create a MariaDB Database and User for Roundcube
Log into MariaDB shell as root.
mysql -u root -p
Then create a new database for Roundcube using the following command. This tutorial name it roundcube
, you can use whatever name you like for the database.
CREATE DATABASE roundcube DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
Next, create a new database user on localhost using the following command. Again, this tutorial name it roundcubeuser
, you can use whatever name you like. Replace password
with your preferred password.
CREATE USER roundcubeuser@localhost IDENTIFIED BY 'password';
Then grant all permission of the new database to the new user so later on Roundcube webmail can write to the database.
GRANT ALL PRIVILEGES ON roundcube.* TO roundcubeuser@localhost;
Flush the privileges table for the changes to take effect.
flush privileges;
Exit MariaDB Shell:
exit;
Run the following command to import the initial tables to roundcube
database. You need to enter the MariaDB root password.
mysql -u root -p roundcube < /var/www/roundcube/SQL/mysql.initial.sql
Step 4: Create Apache Virtual Host or Nginx Config File for Roundcube
Apache
If you use Apache web server, create a virtual host for Roundcube.
sudo nano /etc/httpd/conf.d/roundcube.conf
Note: If you followed my Postfix/Dovecot tutorial, a virtual host already exists. You should edit the following file. (Remove the texts in this file that was added in part 2 and add the new texts below.)
sudo nano /etc/httpd/conf.d/mail.your-domain.com.conf
Put the following text into the file. Replace mail.your-domain.com
with your real domain name and don’t forget to set DNS A record for it.
<VirtualHost *:80>
ServerName mail.your-domain.com
DocumentRoot /var/www/roundcube/
ErrorLog /var/log/httpd/roundcube_error.log
CustomLog /var/log/httpd/roundcube_access.log combined
<Directory />
Options FollowSymLinks
AllowOverride All
</Directory>
<Directory /var/www/roundcube/>
Options FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>
</VirtualHost>
Save and close the file. Reload Apache for the changes to take effect.
sudo systemctl reload httpd
Now you should be able to see the Roundcube web-based install wizard at http://mail.your-domain.com/installer
.
Nginx
If you use Nginx web server, create a virtual host for Roundcube.
sudo nano /etc/nginx/conf.d/roundcube.conf
Note: If you followed my Postfix/Dovecot tutorial, a virtual host already exists. you should edit the following file. (Remove the texts in this file that was added in part 2 and add the new texts below.)
sudo nano /etc/nginx/conf.d/mail.your-domain.com.conf
Put the following text into the file. Replace the domain name and don’t forget to set DNS A record for it.
server {
listen 80;
listen [::]:80;
server_name mail.your-domain.com;
root /var/www/roundcube/;
index index.php index.html index.htm;
error_log /var/log/nginx/roundcube.error;
access_log /var/log/nginx/roundcube.access;
location / {
try_files $uri $uri/ /index.php;
}
location ~ \.php$ {
try_files $uri =404;
fastcgi_pass unix:/run/php-fpm/www.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location ~ /.well-known/acme-challenge {
allow all;
}
location ~ ^/(README|INSTALL|LICENSE|CHANGELOG|UPGRADING)$ {
deny all;
}
location ~ ^/(bin|SQL)/ {
deny all;
}
# A long browser cache lifetime can speed up repeat visits to your page
location ~* \.(jpg|jpeg|gif|png|webp|svg|woff|woff2|ttf|css|js|ico|xml)$ {
access_log off;
log_not_found off;
expires 360d;
}
}
Save and close the file. Then test Nginx configurations.
sudo nginx -t
If the test is successful, reload Nginx for the changes to take effect.
sudo systemctl reload nginx
Now you should be able to see the Roundcube web-based install wizard at http://mail.your-domain.com/installer
.
Step 5: Enabling HTTPS
It’s highly recommended that you use TLS to encrypt your webmail. We can enable HTTPS by installing a free TLS certificate issued from Let’s Encrypt.
If you use Apache, run this command to obtain and install TLS certificate.
sudo certbot --apache --agree-tos --redirect --hsts --staple-ocsp --email [email protected] -d mail.your-domain.com
If you use Nginx, run the following command to obtain and install TLS certificate.
sudo certbot --nginx --agree-tos --redirect --hsts --staple-ocsp --email [email protected] -d mail.your-domain.com
Where
--nginx
: Use the nginx plugin.--apache
: Use the Apache plugin.--agree-tos
: Agree to terms of service.--redirect
: Force HTTPS by 301 redirect.--hsts
: Add the Strict-Transport-Security header to every HTTP response. Forcing browser to always use TLS for the domain. Defends against SSL/TLS Stripping.--staple-ocsp
: Enables OCSP Stapling. A valid OCSP response is stapled to the certificate that the server offers during TLS.
The certificate should now be obtained and automatically installed.
Note: If you followed my Postfix/Dovecot tutorial, and now you install Roundcube on the same server, then certbot will probably tell you that a certificate for mail.your-domain.com
already exists as shown below, so you can choose to install the existing TLS certificate to your web server configuration file.
Step 6: Setting Up Permissions
First, we need to change the SELinux context of the web directory, so it can be used to serve web content.
sudo chcon -t httpd_sys_content_t /var/www/roundcube/ -R
The web server needs to write to the temp
and logs
directory. Change the SELinux context to make it writable.
sudo chcon -t httpd_sys_rw_content_t /var/www/roundcube/temp/ /var/www/roundcube/logs/ -R
Then grant write permission to the web server.
Apache:
sudo setfacl -R -m u:apache:rwx /var/www/roundcube/temp/ /var/www/roundcube/logs/
Nginx:
sudo setfacl -R -m u:nginx:rwx /var/www/roundcube/temp/ /var/www/roundcube/logs/
By default, SELinux forbids Apache/Nginx to make network requests to other servers, but later Apache/Nginx needs to request TLS certificate status from Let’s Encrypt CA server for OCSP stapling, so we need to tell SELinux to allow Apache/Nginx with the following command.
sudo setsebool -P httpd_can_network_connect 1
If you use Nginx, then you also need to run the following command to give the nginx user read and write permissions to 3 directories.
sudo setfacl -R -m u:nginx:rwx /var/lib/php/opcache/ /var/lib/php/session/ /var/lib/php/wsdlcache/
Restart Apache/Nginx.
sudo systemctl restart httpd sudo systemctl restart nginx
Step 7: Finish the Installation in Web Browser
In your web browser, go to the Roundcube installer page.
https://mail.your-domain.com/installer
The web installer will first check if PHP extensions, database and 3rd party libraries are installed. If you follow this tutorial, then all requirements should be met.
Click Next button. In the 2nd page, you need to fill in MariaDB database details that you created in step 3.
The IMAP and SMTP section allows you to configure how to receive and submit email. Enter the following values for IMAP.
- IMAP host:
ssl://mail.your-domain.com
port:993
Enter the following values for SMTP settings.
- SMTP port:
tls://mail.your-domain.com
port:587
. Note that you must usetls://
as the prefix for port 587. Thessl://
prefix should be used for port 465.
Next, you can scroll down to the Plugins
section to enable some plugins. For example: the password plugin, mark as junk plugin and so on. I enabled all of them.
Once that’s done, click create config
button which will create configuration based on the information you entered. You need to copy the configuration and save it as config.inc.php
under the /var/www/roundcube/config/
directory.
Once the config.inc.php
file is created, click continue
button. In the final step, test your SMTP and IMAP settings by sending a test email and checking IMAP login. Note that you need to enter your full email address in the Sender
field when testing SMTP config.
If the test fails, then you can click the 2. Create config
link on the top of page to go back to step 2 and recreate the config.inc.php
file.
If test is successful, go to your Webmail domain without /installer
and login.
Roundcube Webmail interface
Now you should remove the whole installer folder from the document root or make sure that enable_installer
option in config.inc.php
file is disabled.
sudo rm /var/www/roundcube/installer/ -r
These files may expose sensitive configuration data like server passwords and encryption keys to the public. Make sure you cannot access the installer page from your browser.
Step 8: Configure the Sieve Message Filter
You can create folders in Roundcube webmail and then create rules to filter email messages into different folders. In order to do this, you need to install the dovecot-pigeonhole
package with the following command.
sudo dnf install dovecot-pigeonhole
Open the /etc/dovecot/conf.d/15-lda.conf
file.
sudo nano /etc/dovecot/conf.d/15-lda.conf
Scroll to the end of the file, uncomment the mail_plugins
line and add the sieve plugin to local delivery agent (LDA).
protocol lda { # Space separated list of plugins to load (default is global mail_plugins). mail_plugins = $mail_plugins sieve }
Save and close the file. If you can find the 20-lmtp.conf
file under /etc/dovecot/conf.d/
directory, then you should also enable the sieve plugin in that file like below.
protocol lmtp { mail_plugins = quota sieve }
Edit the /etc/dovecot/conf.d/10-mail.conf
file.
sudo nano /etc/dovecot/conf.d/10-mail.conf
Sieve scripts are stored under each user’s home directory. If you followed my PostfixAdmin tutorial and are using virtual mailbox domains, then you need to enable mail_home
for the virtual users by adding the following line in the file, because virtual users don’t have home directories by default.
mail_home = /var/vmail/%d/%n
Save and close the file.
By default, Postfix uses its built-in local delivery agent (LDA) to move inbound emails to the message store (inbox, sent, trash, Junk, etc). We can configure it to use Dovecot to deliver emails, via the LMTP protocol, which is a simplified version of SMTP. LMTP allows for a highly scalable and reliable mail system and it is required if you want to use the sieve plugin to filter inbound messages to different folders.
Edit the Dovecot main configuration file.
sudo nano /etc/dovecot/dovecot.conf
Add lmtp
and sieve
to the supported protocols.
protocols = imap lmtp sieve
Save and close the file. Then edit the Dovecot 10-master.conf file.
sudo nano /etc/dovecot/conf.d/10-master.conf
Change the lmtp
service definition to the following.
service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } }
Next, edit the Postfix main configuration file.
sudo nano /etc/postfix/main.cf
Add the following lines at the end of the file. The first line tells Postfix to deliver emails to local message store via the dovecot LMTP server. The second line disables SMTPUTF8 in Postfix, because Dovecot-LMTP doesn’t support this email extension.
mailbox_transport = lmtp:unix:private/dovecot-lmtp smtputf8_enable = no
Save and close the file. Finally, restart Postfix and Dovecot.
sudo systemctl restart postfix dovecot
Now you can go to Roundcube webmail, open an email message and click the more
button and select create filters
to create message filters. For example, I create a filter that moves every email sent from redhat.com to the Red Hat folder.
If you don’t have the create filter
option, it’s probably because you didn’t enable the managesieve
plugin. Edit the config.inc.php
file.
sudo nano /var/www/roundcube/config/config.inc.php
Add the managesieve
plugin in the array at the end of this file. The plugin order doesn’t matter.
$config['plugins'] = array('acl', 'additional_message_headers', 'managesieve', .....);
Save and close the file.
Note that if you move a sieve filter set from an old mail server to your new mail server, you need to go to Settings -> Filters, then click Actions and enable the filter set, or Dovecot LMTP server won’t execute the sieve filter.
Step 9: Adding Local DNS Entry
It’s recommended to edit the /etc/hosts
file and add the following entry so that Roundcube won’t have to query the public DNS, which will speed up web page loading a little bit.
127.0.0.1 localhost mail.your-domain.com
Step 10: Removing Sensitive Information from Email Headers
By default, Roundcube will add a User-Agent
email header, indicating that you are using Roundcube webmail and the version number. You can tell Postfix to ignore it so recipient can not see it. Run the following command to create a header check file.
sudo nano /etc/postfix/smtp_header_checks
Put the following lines into the file.
/^User-Agent.*Roundcube Webmail/ IGNORE
Save and close the file. Then edit the Postfix main configuration file.
sudo nano /etc/postfix/main.cf
Add the following line at the end of the file.
smtp_header_checks = regexp:/etc/postfix/smtp_header_checks
Save and close the file. Then run the following command to rebuild hash table.
sudo postmap /etc/postfix/smtp_header_checks
Reload Postfix for the change to take effect.
sudo systemctl reload postfix
Now Postfix won’t include User-Agent: Roundcube Webmail
in the headers when sending outgoing emails.
Step 11: Configure the Password Plugin in Roundcube
Roundcube includes a password plugin that allows users to change their passwords from the webmail interface. Edit the config.inc.php
file.
sudo nano /var/www/roundcube/config/config.inc.php
Make sure the password
plugin in the plugin list at the end of this file. The plugin order doesn’t matter.
$config['plugins'] = array('acl', 'additional_message_headers', 'password', .....);
Save and close the file.
However, we need to configure this plugin before it will work. Edit the password plugin configuration file.
sudo nano /var/www/roundcube/plugins/password/config.inc.php
If your Roundcube doesn’t have the config.inc.php file, then copy the default config file and edit the file.
cd /var/www/roundcube/plugins/password/ sudo cp config.inc.php.dist config.inc.php sudo nano config.inc.php
Find the following line:
$config['password_db_dsn'] = '';
This parameter is used to tell the password plugin where the user passwords are stored. By default, the value is empty and it will query the roundcube
database, which doesn’t store user passwords. If you followed my PostfixAdmin tutorial, then user passwords are stored in the postfixadmin
database, so we need to change the value to:
$config['password_db_dsn'] = 'mysql://postfixadmin:postfixadmin_database_password@127.0.0.1/postfixadmin';
The tells the password plugin to connect to the postfixadmin
database. If you don’t remember your postfixadmin database password, you can find it in the /etc/dovecot/dovecot-sql.conf.ext
file.
Then find the following line.
$config['password_query'] = 'SELECT update_passwd(%c, %u)';
Change it to the following.
$config['password_query'] = "UPDATE mailbox SET password=%D,modified=NOW() WHERE username=%u";
I recommend enabling a password strength checker to prevent users from setting week passwords. Go to the beginning of this file, you can find the following line.
$config['password_strength_driver'] = null;
We can use the zxcvbn
password strength driver, so change it to:
$config['password_strength_driver'] = 'zxcvbn';
Add the following line in this file to allow strong passwords only.
$config['password_zxcvbn_min_score'] = 5;
Note: The $config['password_minimum_score']
parameter doesn’t work with the zxcvbn
driver, so leave it alone.
You can also set a minimum length for the password. Find the following line.
$config['password_minimum_length'] = 0;
Change it to:
$config['password_minimum_length'] = 8;
Recall that we used the BLF-CRYPT password scheme in the PostfixAdmin tutorial, so we also need to configure the password plugin to use BLF-CRYPT. Find the following lines in the file.
$config['password_algorithm'] = 'clear';
By default, the password will be stored as clear text, change the value to the following to use Dovecot’s builtin password algorithm.
$config['password_algorithm'] = 'dovecot';
Then find the following line, which tells where the Dovecot’s password hash generator is located.
$config['password_dovecotpw'] = '/usr/local/sbin/dovecotpw'; // for dovecot-1.x
Change it to the following.
$config['password_dovecotpw'] = '/usr/bin/doveadm pw -r 12';
Then find the following line, which tells which password scheme will be used.
$config['password_dovecotpw_method'] = 'CRAM-MD5';
Change it to:
$config['password_dovecotpw_method'] = 'BLF-CRYPT';
Find the following line.
$config['password_dovecotpw_with_method'] = false;
Change false
to true.
This will add a {BLF-CRYPT} prefix to the hashed password, so you will recognize which password scheme is used.
$config['password_dovecotpw_with_method'] = true;
Save and close the file. Since this file contains the database password, we should allow only the web server user to read and write to this file.
Apache
sudo chown apache:apache /var/www/roundcube/plugins/password/config.inc.php sudo chmod 600 /var/www/roundcube/plugins/password/config.inc.php
Nginx
sudo chown nginx:nginx /var/www/roundcube/plugins/password/config.inc.php sudo chmod 600 /var/www/roundcube/plugins/password/config.inc.php
Now users should be able to change their passwords in the Roundcube webmail interface.
How to Set Up Vacation/Out-of-Office Messages
We can use the sieve filter to create vacation/out-of-office messages. Go to Roundcube Settings -> Filters. Then click the create
button to create a filter.
- Give this filer a name like “out of office”.
- New filters are not disabled, so you can leave the button alone.
- In the Scope field, select all messages.
- Select Replay with message in the Actions settings, and enter the message that will be automatically sent.
- Enter 1 in how ofter send messages. Leave other text field empty.
- Click the Save button and you are done.
When you are back to office, you can toggle the “Filter disabled” button, and click the Save button to disable this filter.

Troubleshooting Tips
If you encounter errors, you can check the web server error logs at /var/log/apache2/roundcube_error.log
(if you are using Apache), or /var/log/nginx/roundcube.error
(if you are using Nginx.), also the Roundcube error logs in /var/www/roundcube/logs/
directory.
Connection to Storage Server Failed
If you see the Connection to storage server failed
error when trying to log into RoundCube, it’s probably because
- Dovecot server isn’t running. You can restart Dovecot with
sudo systemctl restart dovecot
and check its status withsystemctl status dovecot
. - You are using a self-signed TLS certificate. Roundcube requires a valid TLS certificate issued from a trusted certificate authority such as Let’s Encrypt.
- Your TLS certificate expired. You can renew the Let’s Encrypt TLS certificate with
sudo certbot renew
, then restart Postfix and Dovecot (sudo systemctl restart postfix dovecot
).
Could Not Load Message From Server
If you see the “Internal error: could not load message from server” error, it’s probabaly because you are trying to open an deleted email (invalid URL). Try going to the mail root domain (mail.example.com) to see if it works.
Wrapping Up
I hope this tutorial helped you install Roundcube Webmail on CentOS 8/RHEL 8. As always, if you found this post useful, subscribe to our free newsletter to get more tips and tricks 🙂
Thanks for sharing.
Thank you for the detailed guide!
Hi,
don’t you have to set owner of /var/www/roundcube to the correct user depending if you’re using roundcube or nginx user ?
regards
The web server needs to have write permission on
/var/www/roundcube/temp/
and/var/www/roundcube/logs/
directory, and have read permission on the main /var/www/roundcube/ directory.HI, great tutorial, just having issues with the roundcube install:
when running commands like:
sudo chcon -t httpd_sys_content_t /var/www/roundcube/ -R
&
sudo chcon -t httpd_sys_rw_content_t /var/www/roundcube/temp/ /var/www/roundcube/logs/ -R
getting lots of error:
chcon: can’t apply partial context to unlabeled file…
How do I get around this?
I think selinux may be disabled if you’re seeing errors like that. enter “sestatus” at the command prompt and see if it’s set to disabled.
Hi, it is a great tutorial, i have used all of its parts to deploy a mail server, and it works perfect!
But I’m having a problem with configuring nginx as it says in step 4 of this tutorial, because a lot of settings appeared in /etc/nginx/conf.d/mail.your-domain.com.conf after previous tutorials.
By adding settings from step 4 as a result I recieve 404, by changing root for https I recieve 403 Forbidden. I have tried to complete further steps, but it didn’t help(((
I’m stuck in it, so it would be very kind if You could help me. THX
Simply remove the texts in this file that was added in part 2 and add the new texts.
hi,
new install of CentOS 8, installed roundcubemail 1.4.9, I can check email, sending email fails just get notification down in lower right corner, which goes away and email never sent. selinux is in permissive mode, I can get it fail if I change the smtp host line from tls to ssl
apache logs and php-fpm logs don’t show anything, anyone know how to trouble shoot this issue?
For sending email:
Prefix
tls://
should be used with port 587 (STARTTLS).Prefix
ssl://
should be used with port 465 (SMTPS).Hello Xiao,
have followed all your tutorials postfix,dovecot,postfixadmin, really appreciate the time you have put in. I seem to be having an issue where. I dont seem to be able to test smtp or imap config, always times out takes forever.
[proxy_fcgi:error] [pid 75448:tid 140460764440320] (70007)The timeout specified has expired: [client IP:34550] AH01075: Error dispatching request to : (polling), referer: https://webmail.domain.co.uk/installer/index.php?_step=3
Any ideas, dont see anything else in any logs postfix,dovecot even checked in amavis.
Hi Xiao,
I am a bit stuck with the roundcube installer.
I created the virtual host as you described but I am not able to access the server/installer and get the following error:
Forbidden
You don’t have permission to access this resource.Server unable to read htaccess file, denying access to be safe
Can you please give me a hint on what is going wrong here?
Thanks very much in advance!
Cheers,

Hi! Great tutorial, followed all steps. My goal is to test SPF and DKIM on my private network (not connected to external DNS servers) thus I do not need an SSL certificate nor any additional encryption. My network contents of two centos8 mail servers and two DNS each pair in its own subnet. DNS servers added to resolv.conf.
I omitted TLS entry in
and similar steps related to SSL/TLS and changed
to
Is that correct? Should I change some more? What should the configuration look like?
I case you need further information, I can easly provide them! 🙂

I’m having trouble importing mysql to /var/www/roundcube/SQL/mysql.initial.sql.
when I tried it the first time it said there was no such file or directory, so I made dir, but I still cant put it in the file there.
How could I solve it ?
I figured it out.
To those who struggle with the same problem:
You have to download roundcube before you can do this.
Tecmint.com had a better explanation on this.
1. wget -c https://github.com/roundcube/roundcubemail/releases/download/1.4.9/roundcubemail-1.4.9-complete.tar.gz
2. tar xzf roundcubemail-1.4.9-complete.tar.gz
3. mv roundcubemail-1.4.9 /var/www/html/roundcubemail
4. cd /var/www/html/roundcubemail/
5. mysql -u root -p roundcubemail flush privileges;
6. Set new password by ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘NewPassword’;
7. Go back to /etc/my.cnf and remove/comment skip-grant-tables
8. Restart Mysql
9. Now you will be able to login with the new password mysql -u root -p
Good luck!
