Install Roundcube on Ubuntu

How to Install Roundcube on Ubuntu 22.04

Roundcube is a free open-source web-based multilingual IMAP email client written in PHP. It provides the full functionality you expect from an email client, including MIME support, address book, folder manipulation, message searching, and spell checking.

This tutorial is going to show you how to install Roundcube webmail on Ubuntu 22.04 with Nginx web server and MySQL database server.

Step 1: Update Operating System

Before you can proceed with installation and configuration of Roundcube webmail on Ubuntu 22.04, update and upgrade your system packages to the latest version with the following command:

# apt update && sudo apt upgrade -y

Step 2: Install Nginx Web Server

In this tutorial, we will use Nginx. If you prefer Apache or another web server, you can use that instead of Nginx.

You can install Nginx via apt package manager by executing the following command.

# apt install nginx

You can start the Nginx service and configure it to run on startup by entering the following commands:

# systemctl start nginx
# systemctl enable nginx

Verify the status of the Nginx service using systemctl status command:

# systemctl status nginx

Output:

 nginx.service - A high performance web server and a reverse proxy server
     Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
     Active: active (running)
       Docs: man:nginx(8)
   Main PID: 5317 (nginx)
      Tasks: 2 (limit: 2196)
     Memory: 2.6M
        CPU: 31ms
     CGroup: /system.slice/nginx.service
             ├─5317 "nginx: master process /usr/sbin/nginx -g daemon on; master_process on;"
             └─5318 "nginx: worker process

Step 3: Install PHP and required PHP extensions for Roundcube

Run the following command to install the required PHP extensions. PHP8.1 is fully supported in the 1.6 release.

# apt install php php-fpm php-gd php-common php-json php-imagick php-imap php-xml php-mbstring php-curl php-zip php-bz2 php-intl php-ldap

Verify if PHP is installed.

# php -v
Output:
PHP 8.1.2-1ubuntu2.9 (cli) (built: Oct 19 2022 14:58:09) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.1.2, Copyright (c) Zend Technologies
    with Zend OPcache v8.1.2-1ubuntu2.9, Copyright (c), by Zend Technologies

Step 4: Install MySQL and create a database

You can install the MySQL server with the following command:

# apt install mysql-server

Start the database server daemon, and also enable it to start automatically at the next boot with the following commands:

# systemctl start mysql
# systemctl enable mysql

Verify the status of the MySQL service using systemctl status command:

# systemctl status mysql

Output:

 mysql.service - MySQL Community Server
     Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled)
     Active: active (running)
   Main PID: 1083 (mysqld)
     Status: "Server is operational"
      Tasks: 41 (limit: 2797)
     Memory: 434.0M
        CPU: 1min 57.932s
     CGroup: /system.slice/mysql.service
             └─1083 /usr/sbin/mysqld

By default, MySQL is not hardened. You can secure MySQL using the mysql_secure_installation script.

# mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] Y
- Remove anonymous users? [Y/n] Y
- Disallow root login remotely? [Y/n] Y
- Remove test database and access to it? [Y/n] Y
- Reload privilege tables now? [Y/n] Y

Now run the command below to log in to the MySQL shell.

# mysql -u root -p

Once you are logged in to your database server you need to create a database for the Roundcube installation:

mysql> CREATE DATABASE roundcubemail;
mysql> CREATE USER 'roundcube'@'localhost' IDENTIFIED BY 'Strong-Password';
mysql> GRANT ALL PRIVILEGES ON roundcubemail . * TO 'roundcube'@'localhost';
mysql> FLUSH PRIVILEGES;
mysql> exit;

Step 5: Download Roundcube

Roundcube is availble on the default Ubuntu repos. However, the repositories do not usually provide an up-to-date version.

The latest stable release version for Roundcube can be installed by downloading the source code from the Roundcube downloads page.

Using the address with wget, download the Roundcube tarball on the server:

# wget https://github.com/roundcube/roundcubemail/releases/download/1.6.0/roundcubemail-1.6.0-complete.tar.gz

Create a roundcube directory:

# mkdir /var/www/roundcube/

After that, you will need to decompress the Roundcube archive:

# tar -xvzf roundcubemail-1.6.0-complete.tar.gz -C /var/www/roundcube/ --strip-components 1

Make Nginx the owner of the roundcube folder and grant it sufficient permissions.

# chown -R www-data:www-data /var/www/roundcube
# chmod 755 -R /var/www/roundcube

Now start the example database included in the downloaded file.

# mysql -u roundcube -p roundcube < /var/www/roundcube/SQL/mysql.initial.sql

Step 6: Configure Nginx for Roundcube

Then, create an virtual host configuration file to host Roundcube:

# nano /etc/nginx/conf.d/roundcube.conf

Nginx ignores Roundcube’s Apache .htaccess files, so we’re telling Nginx to ignore some sensitive directories:

server {
        listen 80;

        server_name webmail.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 ~ ^/(README.md|INSTALL|LICENSE|CHANGELOG|UPGRADING)$ {
            deny all;
        }

        location ~ ^/(config|temp|logs)/ {
            deny all;
        }

        location ~ /\. {
            deny all;
        }

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/run/php/php8.1-fpm.sock;
        }
}

Remember to replace your-domain.com with the domain name of your server.

Save and exit the configuration file.

Check Nginx syntax:

# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

To implement the changes, restart Nginx webserver:

# systemctl restart nginx

Step 7: Roundcube Setup and Configurations

Now open your web browser and go to http://webmail.your-domain.com/installer and you will see the following screen:

Roundcube Webmail Installer

If all required modules and extensions are installed, press NEXT and go to the next step.

On the next page, navigate to Database Setup settings and enter the database name, user and password that you created above.

Roundcube Database Setup

Under SMTP settings, check the box ‘Use the current IMAP username and password for SMTP authentication’:

SMTP Settings

After complete configuration , Press CREATE CONFIG to finish the installation. You will then be notified that the configuration has been successfully created.

Webmail Installer

 

Once everything is setup and working, open your terminal and remove the installation directory with the following command:

# rm -rf /var/www/roundcube/install/

And now go to http://webmail.your-domain.com so you can log in.
