System Requirements

Before installing Roundcube, ensure your Debian 12 system meets the following requirements:

• Web Server: Apache or Nginx.
• Database Server: MySQL or MariaDB.
• PHP: Version 8.1 or higher, with required extensions.
• Mail Server: Postfix or Exim (for sending emails).

Prerequisites

LAMP Stack Components

To run Roundcube, you need a fully functional LAMP (Linux, Apache, MySQL, PHP) stack. Here’s how to ensure each component is properly set up:

• Linux: Debian 12 is the base operating system.
• Apache: Install Apache using the following command:

sudo apt update
 sudo apt install apache2 libapache2-mod-php -y

• MySQL/MariaDB: Install MariaDB using:

sudo apt install mariadb-server mariadb-client -y

• PHP: Install PHP and necessary extensions:

sudo apt install php php-mysql php-mbstring php-imap php-intl php-xml php-gd php-curl php-zip php-common -y

Mail Server Configuration

A mail server like Postfix is required to send emails from Roundcube. Install Postfix with:

sudo apt install postfix -y

During the installation, you’ll be prompted to select a configuration type. Choose “Internet Site” and enter your domain name.

Domain and DNS Setup

Ensure you have a domain name and that it’s properly configured to point to your server’s IP address. This involves setting up DNS records (A and MX records) at your domain registrar.

Installation Methods

Using Package Manager

The simplest way to install Roundcube is via Debian’s package manager, APT. This method automatically handles dependencies and simplifies the installation process.

1. Update APT Database:

sudo apt update

2. Install Roundcube:

sudo apt install roundcube -y

3. Configure Apache:
   During installation, you’ll be asked to configure Roundcube for Apache. Select “Yes” to allow dbconfig-common to set up the database.
4. Access Roundcube:
   After installation, access Roundcube by navigating to http://your_domain/roundcube in your web browser.

Manual Installation

For more control over the installation process, you can manually install Roundcube from the source.

1. Download from Source:
   Download the latest stable version of Roundcube from the official website or GitHub.

wget https://github.com/roundcube/roundcubemail/releases/download/1.7.6/roundcubemail-1.7.6-complete.tar.gz

Replace 1.7.6 with the latest version number.

2. Extract and Place Files:
   Extract the downloaded archive and move the Roundcube files to your web server’s root directory.

tar xvf roundcubemail-1.7.6-complete.tar.gz
 sudo mkdir -p /var/www/html/
 sudo mv roundcubemail-1.7.6 /var/www/html/roundcube

3. Permission Settings:
   Set the correct permissions for the Roundcube directory to ensure the web server can access the files.

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

4. Web Server Configuration:
   Create an Apache configuration file for Roundcube.

sudo nano /etc/apache2/conf-available/roundcube.conf

Add the following content, adjusting the Directory path to match your setup:

Alias /roundcube /var/www/html/roundcube/
 

 <Directory /var/www/html/roundcube/>
  Options FollowSymLinks
  AllowOverride All
  Require all granted
 </Directory>

Enable the configuration and restart Apache:

sudo a2enconf roundcube
 sudo systemctl restart apache2

Database Configuration

Setting up MySQL/MariaDB

Roundcube requires a database to store user data, settings, and messages. Here’s how to set up a MySQL/MariaDB database.

1. Create Database:
   Log in to your MySQL/MariaDB server and create a new database for Roundcube.

sudo mysql -u root -p
 CREATE DATABASE roundcube;

2. User Privileges:
   Create a user with appropriate privileges for the Roundcube database.

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

Replace 'password' with a strong, unique password.

3. Database Initialization:
   Import the Roundcube database schema.

cd /var/www/html/roundcube
 sudo mysql -u roundcubeuser -p roundcube < SQL/mysql.initial.sql

Security Considerations

• Strong Passwords: Always use strong passwords for your database user and Roundcube administrator account.
• Firewall: Configure your firewall to allow traffic only on necessary ports (e.g., 80 for HTTP, 443 for HTTPS)..
• Regular Backups: Implement regular database backups to prevent data loss.

Roundcube Configuration

Essential Settings

After setting up the database, configure Roundcube to connect to it and set other essential parameters.

1. Core Configuration:
   Copy the sample configuration file.

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

2. Edit Configuration File:
   Open the configuration file for editing.

sudo nano /var/www/html/roundcube/config/config.inc.php

3. Database Connection:
   Set the database connection string.

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

Replace roundcubeuser, password, and roundcube with your actual database credentials.

4. IMAP/SMTP Setup:
   Define your email server IMAP and SMTP addresses. For example, using Gmail:

 $config['default_host'] = 'tls://imap.gmail.com';
 $config['default_port'] = 993;
 $config['smtp_server'] = 'tls://smtp.gmail.com';
 $config['smtp_port'] = 587;
 $config['smtp_auth_type'] = 'LOGIN';
 $config['smtp_username'] = '%u';
 $config['smtp_password'] = '%p';

If you use Gmail, you will need to generate an app password.

Security Parameters

• des_key: Generate a unique key for encrypting sensitive data.

 $config['des_key'] = 'your_unique_key';

• plugins: Enable necessary plugins, such as 'archive', 'zipdownload', and 'password'.

 $config['plugins'] = array('archive', 'zipdownload', 'password');

PHP Requirements

Ensure your PHP environment meets Roundcube’s requirements. Install any missing extensions using APT.

Testing and Verification

Post-Installation Checks

After installation, perform these checks to ensure Roundcube is working correctly.

• Web Interface: Access Roundcube via your web browser to ensure the interface loads correctly.
• Email Functionality: Send and receive test emails to verify that the mail server is properly configured.
• Login: Test user login functionality.

Security Verification

• SSL/TLS: Ensure your Roundcube installation uses SSL/TLS to encrypt traffic.
• Permissions: Verify that file permissions are correctly set to prevent unauthorized access.

Troubleshooting Common Issues

• Configuration File Errors: Check the Roundcube configuration file for syntax errors or incorrect settings.
• Directory Write Permissions: Ensure that Roundcube directories have the necessary write permissions.
• Database Connection Issues: Verify the database connection settings in the configuration file.

Maintenance and Updates

Keeping Roundcube Updated

Regularly update Roundcube to ensure you have the latest features and security patches.

1. Update Procedures:
   To update Roundcube, download the latest version and replace the existing files, then update the database schema if necessary.
2. Backup Strategies:
   Before updating, always back up your Roundcube directory and database.
3. Security Patches:
   Apply security patches as soon as they are released to protect your webmail client from vulnerabilities.
