Prerequisites for Installing Roundcube on CentOS

Before diving into the installation process, ensure your server meets the following prerequisites:

  • CentOS 7 or higher: Ensure your operating system is up-to-date.
  • PHP 7.2 or higher: Roundcube requires a compatible version of PHP. Also, install necessary PHP extensions such as:
    • php-mbstring
    • php-xml
    • php-mcrypt

    • php-json
  • Web Server: Apache or Nginx, configured and running.

Step-by-Step Guide to Install Roundcube on CentOS

Step 1: Update Your System

Start by ensuring your system is fully updated. Run the following command:

sudo yum update -y

Step 2: Install Required Software

You can install the necessary software packages by executing:

sudo yum install httpd mariadb-server php php-mbstring php-xml php-mcrypt php-intl php-json -y

Step 3: Start and Enable Services

Once the installation completes, start the Apache and MariaDB services and enable them to start on boot:

sudo systemctl start httpd sudo systemctl start mariadb sudo systemctl enable httpd sudo systemctl enable mariadb

Step 4: Create a Database for Roundcube

Secure your MariaDB installation and create a database for Roundcube:

sudo mysql_secure_installation

Then log in to MariaDB:

mysql -u root -p

Once logged in, create a new database and user:

CREATE DATABASE roundcube; CREATE USER 'roundcubeuser'@'localhost' IDENTIFIED BY 'yourpassword'; GRANT ALL PRIVILEGES ON roundcube.* TO 'roundcubeuser'@'localhost'; FLUSH PRIVILEGES; EXIT;

Step 5: Download Roundcube

Download the latest version of Roundcube from the official website:

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

Set the correct permissions:

sudo chown -R apache:apache /var/www/html/roundcubemail

Step 6: Configure Roundcube

Now it's time to configure Roundcube. Navigate to the Roundcube config directory:

cd /var/www/html/roundcubemail/config

Copy the default configuration file:

cp config.inc.php.sample config.inc.php

Open config.inc.php with a text editor and set the database details you created earlier:

$config['db_dsnw'] = 'mysql://roundcubeuser:yourpassword@localhost/roundcube';

Step 7: Set Up the Web Server

To make Roundcube accessible, configure your web server. If you are using Apache, create a new virtual host:

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

Then add the following configuration:

ServerName mail.yourdomain.com DocumentRoot /var/www/html/roundcubemail Options Indexes FollowSymLinks AllowOverride All Require all granted ErrorLog /var/log/httpd/roundcube_error.log CustomLog /var/log/httpd/roundcube_access.log combined

Change yourdomain.com to your actual domain name.

Step 8: Restart Apache

Finally, to apply the changes, restart Apache:

sudo systemctl restart httpd

Step 9: Finish Installation via Web Interface

Open your web browser and navigate to http://mail.yourdomain.com/installer. Follow the on-screen instructions to complete the installation. Once done, remember to remove the installer directory for security:

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