Introduction<\/strong><\/h3>\n

This is the second part of our guide on building a complete email server. In\u00a0Part 1<\/a>, we configured Postfix (SMTP) and Dovecot (IMAP\/POP3), allowing you to send and receive emails via the command line.<\/p>\n

Now, we will install\u00a0Roundcube<\/strong><\/a>, a modern, browser-based webmail client that provides a user-friendly interface similar to Gmail or Outlook. This involves setting up a LAMP stack (Linux, Apache, MariaDB, PHP) to run Roundcube.<\/p>\n

\n

Step 1: Install the LAMP Stack<\/strong><\/h3>\n

Roundcube requires a web server, a database, and PHP. We will install and configure these components.<\/p>\n

1.1 Install Apache, PHP, and MariaDB:<\/strong>
Install all required packages with a single command:<\/p>\n

\n
\n
\n
\n
bash<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
sudo<\/span> yum install<\/span> -y<\/span> httpd php php-fpm php-mcrypt php-cli php-gd php-curl php-xml php-mysql php-mbstring php-pspell php-imagick mariadb-server<\/pre>\n<\/div>\n
1.2 Start and Enable Services:<\/strong><\/p>\n
\n
\n
\n
\n
bash<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
sudo<\/span> systemctl start httpd mariadb\nsudo<\/span> systemctl enable<\/span> httpd mariadb<\/pre>\n<\/div>\n
1.3 Configure PHP Settings:<\/strong>
Edit the main PHP configuration file to set your timezone.<\/p>\n
\n
\n
\n
\n
bash<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
sudo<\/span> vi<\/span> \/etc\/php.ini<\/pre>\n<\/div>\n
Find the line\u00a0;date.timezone =<\/code>\u00a0and modify it to your region. Remove the semicolon (;<\/code>) to uncomment it.<\/p>\n
\n
\n
\n
\n
ini<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
date.timezone<\/span> =<\/span> \"Asia\/Kolkata<\/span>\"<\/span><\/pre>\n<\/div>\n
Save the file and restart Apache to apply the changes.<\/p>\n
\n
\n
\n
\n
bash<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
sudo<\/span> systemctl restart httpd<\/pre>\n<\/div>\n
\n
Pro Tip:\u00a0You can find a list of supported timezones\u00a0here<\/a>. Using the correct timezone is crucial for accurate email timestamps.<\/strong><\/p>\n<\/blockquote>\n
\n
Step 2: Configure MariaDB Database<\/strong><\/h3>\n
2.1 Secure MariaDB Installation:<\/strong>
Run the security script to set a root password and remove insecure defaults:<\/p>\n
\n
\n
\n
\n
bash<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
sudo<\/span> mysql_secure_installation<\/pre>\n<\/div>\n
Follow the prompts to set a root password, remove anonymous users, disallow remote root login, and remove the test database.<\/p>\n
2.2 Create a Database for Roundcube:<\/strong>
Log into MariaDB and create a dedicated database and user for Roundcube for better security.<\/p>\n
\n
\n
\n
\n
bash<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
mysql -u<\/span> root -p<\/span><\/pre>\n<\/div>\n
Enter your root password when prompted, then run the following SQL commands inside the MariaDB shell:<\/p>\n
\n
\n
\n
\n
sql<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
CREATE<\/span> DATABASE<\/span> roundcubemail;<\/span>\nCREATE<\/span> USER<\/span> 'roundcube'<\/span>@'localhost'<\/span> IDENTIFIED BY<\/span> '=213@!#webL'<\/span>;<\/span>\nGRANT<\/span> ALL<\/span> PRIVILEGES<\/span> ON<\/span> roundcubemail.<\/span>*<\/span> TO<\/span> 'roundcube'<\/span>@'localhost'<\/span>;<\/span>\nFLUSH PRIVILEGES<\/span>;<\/span>\nEXIT<\/span>;<\/span><\/pre>\n<\/div>\n
http:\/\/mail.you_domain.com\/roundcube\/installer<\/span><\/a><\/p>\n
<\/p>\n
Step 3: Install and Configure Roundcube<\/strong><\/h3>\n
3.1 Download Roundcube:<\/strong>
Navigate to the web root directory and download the latest stable version of Roundcube.\u00a0(Note: Check the\u00a0Roundcube download page<\/a>\u00a0for the most recent version.)<\/em><\/p>\n
\n
\n
\n
\n
bash<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
cd<\/span> \/tmp\nsudo<\/span> wget<\/span> -c<\/span> https:\/\/github.com\/roundcube\/roundcubemail\/releases\/download\/1.3.7\/roundcubemail-1.3.7-complete.tar.gz<\/pre>\n<\/div>\n
3.2 Extract and Move Files:<\/strong>
Extract the downloaded archive and move it to your web directory.<\/p>\n
\n
\n
\n
\n
bash<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
sudo<\/span> tar<\/span> xzf roundcubemail-1.3.7-complete.tar.gz\nsudo<\/span> mv<\/span> roundcubemail-1.3.7 \/var\/www\/html\/roundcubemail<\/pre>\n<\/div>\n
\"Roundcube<\/p>\n
    \n
  1. \n
    3.3 Import the Database Schema:<\/strong>
    Import the initial database structure into your\u00a0roundcubemail<\/code>\u00a0database.<\/p>\n
    \n
    \n
    \n
    \n
    bash<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
    cd<\/span> \/var\/www\/html\/roundcubemail\nsudo<\/span> mysql -u<\/span> root -p<\/span> roundcubemail <<\/span> SQL\/mysql.initial.sql<\/pre>\n<\/div>\n
    3.4 Set Correct Permissions:<\/strong>
    Apache needs to own the files to read and write to them.<\/p>\n
    \n
    \n
    \n
    \n
    bash<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
    sudo<\/span> chown<\/span> -R<\/span> apache:apache \/var\/www\/html\/roundcubemail<\/pre>\n<\/div>\n
    3.5 Restart Services:<\/strong><\/p>\n
    \n
    \n
    \n
    \n
    bash<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n
    sudo<\/span> systemctl restart httpd mariadb<\/pre>\n<\/div>\n
    \"Roundcube<\/p>\n<\/li>\n<\/ol>\n
    Roundcube Configuration File Created<\/span><\/p>\n
    You can review your configuration from the <\/span>Test config page<\/span> as shown in the following screenshot.<\/span><\/p>\n
    \"Test<\/p>\n
    \"Roundcube<\/p>\n
    Step 4: Complete Setup via Web Browser<\/strong><\/h3>\n
    The final configuration is done through a web-based installer.<\/p>\n
      \n
    1. \n
      Open your browser and navigate to your Roundcube installer:
      http:\/\/mail.your_domain.com\/roundcubemail\/installer<\/code><\/p>\n<\/li>\n
