Prerequisites for Installation

Before diving into the installation of Roundcube on CentOS 7, ensure you have the following:

  • A running instance of CentOS 7.
  • Access to root or sudo user permissions on the server.
  • A LAMP stack (Linux, Apache, MySQL/MariaDB, PHP) installed and configured.
  • Basic knowledge of terminal commands.

Step 1: Update Your System

Start by making sure your system is up to date. Open your terminal and execute the following commands:

sudo yum update -y

This command ensures that all packages on your CentOS 7 server are current, minimizing the chances of compatibility issues during installation.

Step 2: Install Required Dependencies

Roundcube requires several PHP extensions. Install the necessary dependencies with the following command:

sudo yum install httpd mariadb-server php php-mysqlnd php-mbstring php-xml php-intl php-json php-gd php-zip -y

After installation, start the Apache and MariaDB services:

sudo systemctl start httpd sudo systemctl start mariadb

To ensure they start on boot, use:

sudo systemctl enable httpd sudo systemctl enable mariadb

Step 3: Configure the Database

Roundcube requires a database to store information. To set this up:

  1. Log into your MariaDB server:
    2. sudo mysql -u root -p
  2. Create a new database for Roundcube:
    3. CREATE DATABASE roundcube;
  3. Create a new user and grant permissions:
    4. GRANT ALL PRIVILEGES ON roundcube.* TO 'roundcube_user'@'localhost' IDENTIFIED BY 'your_password';
  4. Flush privileges and exit:
    5. FLUSH PRIVILEGES; EXIT;

Make sure to replace your_password with a strong password.

Step 4: Download and Install Roundcube

Now that we have the database set up, it’s time to download Roundcube. Use the following commands:

cd /var/www/html sudo curl -O 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

Next, set the correct permissions:

sudo chown -R apache:apache /var/www/html/roundcube sudo chmod -R 755 /var/www/html/roundcube

Step 5: Configure Roundcube

Roundcube is configured via a config file located in the config directory. Navigate to this directory and copy the sample configuration file:

cd /var/www/html/roundcube/config sudo cp config.inc.php.sample config.inc.php

Edit the configuration file:

sudo nano config.inc.php

Within this file, make the following important adjustments:

  • Set your database parameters:
    • 'db_dsnw' => 'mysql://roundcube_user:your_password@localhost/roundcube',
  • Adjust the default hostname and service settings appropriate for your setup.

Step 6: Set Up Web Server Configuration

To ensure Apache serves the Roundcube application correctly, create a new configuration file:

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

Add the following lines:

Options Indexes FollowSymLinks AllowOverride All Require all granted Alias /roundcube "/var/www/html/roundcube/" DirectoryIndex index.php

Restart Apache to apply changes:

sudo systemctl restart httpd
