  • Drag-and-drop functionality

With its rich feature set, it’s no wonder that many organizations prefer Roundcube for their email services. Now, let’s delve into the installation process!

Pre-requisites for Installing Roundcube on CentOS 7

Before starting the installation of Roundcube, ensure that your CentOS 7 server meets the following requirements:

  • Apache Web Server: Roundcube is server dependent; thus, you’ll need to have the Apache web server installed.
  • PHP (Version 7.2 or higher): Make sure PHP is installed, as Roundcube is built on it.
  • MySQL or PostgreSQL: Choose a database system to manage your email data.
  • IMAP Server: You must have an IMAP server set up to access your emails.
  • cURL and PEAR: These PHP modules should be installed for enhanced functionality.

Once you've ensured that your server meets the above requirements, you are ready to perform the installation steps.

Step 1: Updating Your System

It's critical to start with an up-to-date system. Open your terminal and run the following commands:

sudo yum clean all sudo yum update

These commands will ensure your CentOS 7 installation is fully updated, giving you the best compatibility for new software.

Step 2: Installing Required Packages

You will need to install several packages to support Roundcube. Use the command below to install Apache, PHP, and the necessary PHP extensions:

sudo yum install -y httpd php php-mysql php-mbstring php-xml php-json php-curl

To install the database server, you can choose either MySQL or MariaDB. For instance, if you prefer MariaDB, run:

sudo yum install -y mariadb-server

After installation, make sure to start the MariaDB service:

sudo systemctl start mariadb sudo systemctl enable mariadb

Step 3: Configuring MySQL/MariaDB

Once your database service is up, you need to secure it by running:

sudo mysql_secure_installation

This script will guide you through a series of prompts to enhance the security of your MariaDB installation. Set a strong root password and opt to remove anonymous users and disallow remote root login.

Step 4: Creating a Database for Roundcube

Next, create a database and a user for the Roundcube installation. Log in to your database system:

sudo mysql -u root -p

Then, execute the following commands to create a database and user:

CREATE DATABASE roundcube_db; GRANT ALL PRIVILEGES ON roundcube_db.* TO 'roundcube_user'@'localhost' IDENTIFIED BY 'your_password'; FLUSH PRIVILEGES; EXIT;

Make sure to replace 'your_password' with a strong password that you will remember.

Step 5: Downloading Roundcube

Now it’s time to download the latest version of Roundcube. You can find the official link on the Roundcube website. Use the following commands to download and extract the package:

cd /var/www/html sudo wget https://github.com/roundcube/roundcubemail/releases/download/1.6.0/roundcubemail-1.6.0-complete.tar.gz sudo tar -xvzf roundcubemail-1.6.0-complete.tar.gz sudo mv roundcubemail-1.6.0 roundcube

Step 6: Configuring Roundcube

Before you can use Roundcube, you need to configure it. First, create a configuration file by copying the default:

cd roundcube sudo cp config/config.inc.php.sample config/config.inc.php

Next, open the configuration file with your preferred text editor:

sudo nano config/config.inc.php

Locate the following line and set your database connection details:

$config['db_dsnw'] = 'mysql://roundcube_user:your_password@localhost/roundcube_db';

Modify other settings as needed, such as `$config['default_host'] = 'localhost';` to match your IMAP server.

Step 7: Setting Up Apache Virtual Host

To make Roundcube accessible via a web browser, create an Apache configuration file. Use the following command:

sudo nano /etc/httpd/conf.d/roundcube.conf

Add the following configuration:

Alias /roundcube /var/www/html/roundcube Options Indexes FollowSymLinks AllowOverride All Require all granted

Save the file and exit the text editor. Next, restart Apache to apply the changes:

sudo systemctl restart httpd

Step 8: Completing the Installation

With everything set up, you can now access Roundcube's web installer by navigating to http://your_domain.com/roundcube/installer in your web browser. Follow the prompts to complete the installation. Once finished, you should delete the installer directory for security reasons:

sudo rm -rf /var/www/html/roundcube/installer

Step 9: Finalizing Roundcube Configuration

After installation, it’s important to make additional configurations for optimal performance. Consider the following:

  • Configure plugins: Roundcube supports various plugins that you can enable based on your needs.
  • Enhance security: Implement SSL/TLS to enhance security when accessing the webmail client.
  • Regular backups: Schedule regular backups of your Roundcube database and email data.
