How To Install Roundcube Webmail on Ubuntu 20.04 LTS

Install Roundcube Webmail on Ubuntu 20.04

In this tutorial, we will show you how to install Roundcube Webmail on Ubuntu 20.04 LTS.  For those of you who didn’t know, Roundcube is a free and open-source webmail software written in PHP. 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. It has a clean user interface and provides many features like full support for MIME and HTML messages, multilingual capabilities, find-as-you-type address book, threaded message listing, spells checking, and many more.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of Roundcube on the Ubuntu 20.04 LTS Focal Fossa server.

Install Roundcube Webmail on Ubuntu 20.04 LTS Focal Fossa

Step 1. First, make sure that all your system packages are up-to-date by running the following apt commands in the terminal.

sudo apt update
sudo apt upgrade

Step 2. Install LAMP server.

A Ubuntu 20.04 LAMP stack server is required. If you do not have LAMP installed, you can follow our guide here.

Step 3. Installing Roundcube Webmail on Ubuntu 20.04.

Run the following command to download the latest stable version from the Roundcube Github repository:

wget -P /tmp/ https://github.com/roundcube/roundcubemail/releases/download/1.4.6/roundcubemail-1.4.6-complete.tar.gz

Extract the Roundcube tarball archive to your webroot directory:

tar xvf roundcubemail-1.4.6-complete.tar.gz
sudo mv roundcubemail-1.4.6 /var/www/roundcube

We will need to change some folders permissions:

chown -R www-data.www-data /var/www/roundcube
chmod -R 775 /var/wwwroundcube/{temp,logs}

Step 4. Configuring MariaDB for Roundcube.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. You should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB.

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

Next, we will need to log in to the MariaDB console and create a database for the Roundcube Webmail. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for Roundcube installation:

MariaDB [(none)]> CREATE DATABASE roundcube DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
MariaDB [(none)]> CREATE USER [email protected] IDENTIFIED BY 'your-password';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON roundcube.* TO [email protected];
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> \q

Step 5. Configure Apache VirtualHost for Roundcube.

Now we create a dedicated Apache VirtualHost configuration file for Roundcube:

sudo nano /etc/apache2/sites-available/roundcube.conf
<VirtualHost *:80>
  ServerName mail.idroot.us
  DocumentRoot /var/www/roundcube/

  ErrorLog ${APACHE_LOG_DIR}/roundcube_error.log
  CustomLog ${APACHE_LOG_DIR}/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. Then enable this virtual host with:

sudo a2ensite roundcube.conf
sudo systemctl reload apache2

Step 5. Enabling HTTPS.

We recommended that you use TLS to encrypt your webmail. We can enable HTTPS by installing a free TLS certificate issued from Let’s Encrypt. Run the following command to install Let’s Encrypt:

sudo apt install python3-certbot-apache

Next, run the following command to obtain and install a TLS certificate:

sudo certbot --apache --agree-tos --redirect --hsts --staple-ocsp --email [email protected] -d mail.idroot.us

Step 6. Accessing Roundcube Web Interface.

Roundcube Webmail will be available on HTTP port 80 by default. Open your favorite browser and navigate to https://mail.your-domain.com/installer or https://your-server-ip/installer and complete the required steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.
