Installing Roundcube Webmail on CentOS 8 should take less than 15 minutes to complete. We will be using our <a href=\"https:\/\/www.rosehosting.com\/linux-vps-hosting\/\" target=\"_blank\" rel=\"noreferrer noopener\">SSD <\/a><a href=\"https:\/\/www.rosehosting.com\/linux-vps-hosting\/\">1 VPS<\/a> plan with CentOS 8 for this tutorial. Let&#8217;s start.<\/p>\n\n\n\n<!--more-->\n\n\n\n<h2 class=\"wp-block-heading\">Prerequisites<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>A <a href=\"https:\/\/www.rosehosting.com\/centos-hosting.html\">CentOS 8 VPS<\/a> installation with full root access.<\/li><li>A working Postfix and Dovecot set up on your server with an email account already created.<\/li><li>A subdomain pointing to your server IP address as the main domain for our RoundCube Webmail installation.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Step 1: Log in via SSH and Update Packages<\/h2>\n\n\n\n<p>First, log in to your CentOS 8 VPS via SSH as the root user using your favorite terminal:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">ssh root@ip_address -p port_number<\/pre>\n\n\n\n<p>Once logged in, it is best to update all the CentOS 8 packages installed to make sure they are running on their latest versions. Simply run the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">yum update -y\n<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Step 2: Installing LEMP Stack<\/h2>\n\n\n\n<p>As mentioned earlier, Roundcube is written with PHP and works with MySQL as its data storage. To make it work on our CentOS 8 VPS, we need to set up a LEMP (Linux, Nginx, MySQL, PHP) stack first.<\/p>\n\n\n\n<p>To install and set up the Nginx web server, use the following command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">yum install nginx -y<\/pre>\n\n\n\n<p>Then we need to enable at boot, start, and verify that the Nginx service is running without issues:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">systemctl enable nginx\nsystemctl start nginx\nsystemctl status nginx<\/pre>\n\n\n\n<p>Next to install in the stack is PHP. Roundcube requires php-imap extension which is not included with CentOS 8&#8217;s repository by default. With that said, we need to install the Remi Repository for CentOS 8 to provide us additional PHP modules. In this setup, we will be installing the latest PHP version, PHP 7.4.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">yum install https:\/\/rpms.remirepo.net\/enterprise\/remi-release-8.rpm\nyum module reset php\nyum module enable php:remi-7.4 -y<\/pre>\n\n\n\n<p>Once the repository is set up, we can now proceed to install PHP and the PHP packages required by Roundcube Webmail:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">yum -y install php-fpm php-ldap php-imagick php-common php-gd php-imap php-json php-curl php-zip php-xml php-mbstring php-bz2 php-intl php-gmp<\/pre>\n\n\n\n<p>Since we will be using PHP-FPM, it will be a service that we need to enable at boot, start, and check if running.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">systemctl enable php-fpm\nsystemctl start php-fpm\nsystemctl status php-fpm<\/pre>\n\n\n\n<p>Finally, to complete the stack, we need to install the MySQL database. We will be using MariaDB (a fork of MySQL) as our database service.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">yum install mariadb-server -y<\/pre>\n\n\n\n<p>Once installed, we need to secure the database installation which can be done by simply using the built-in command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">mysql_secure_installation<\/pre>\n\n\n\n<p>At the first prompt, just press <strong>Enter <\/strong>since by default there is no password for root. Then answer <strong>Y<\/strong> for the rest of the questions.<\/p>\n\n\n\n<p>Then same with Nginx, we need to make sure the MariaDB service is working as expected and will automatically start at boot:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">systemctl enable mariadb\nsystemctl start mariadb\nsystemctl status mariadb<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Step 3: Creating the database<\/h2>\n\n\n\n<p>Setting up a database for our Roundcube Webmail installation is fairly easy. We will need to create the database, create and assign a database user, then apply full privileges on that database user to the database. We can do all of this directly via MySQL CLI. To proceed, login as root first:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">mysql -u root -p<\/pre>\n\n\n\n<p>Once logged in, we can now create the database using the following syntax:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">CREATE DATABASE roundcube_db;<\/pre>\n\n\n\n<p><strong>NOTE:<\/strong> <em>All text with red font means that it can be modified as you like.<\/em><\/p>\n\n\n\n<p>Next, create the database user by using the one-line command. Do not forget to set a strong password. Generally, a password utilizing at least 12 characters including alphanumeric and grammatical symbols is sufficient. Never use passwords based upon dictionary words or significant dates.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">CREATE USER &#039;roundcube_user&#039;@&#039;localhost&#039; IDENTIFIED BY &#039;StR0n6_P@$sW0rD&#039;;<\/pre>\n\n\n\n<p>We then need to assign the newly created database user to the newly created database with full privileges:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">GRANT ALL ON roundcube_db.* TO &#039;roundcube_user&#039;@&#039;localhost&#039; IDENTIFIED BY &#039;StR0n6_P@$sW0rD&#039;;<\/pre>\n\n\n\n<p>Finally, we need to flush the privileges then exit MySQL CLI since we are done:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">FLUSH PRIVILEGES;\nexit;<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Step 4: Installing and Setting Up Roundcube Files<\/h2>\n\n\n\n<p>Now that we have LEMP stack running and the database for our Roundcube Webmail is ready, we can now download Roundcube&#8217;s latest stable release. As of writing, the latest stable version available is <strong>v1.4.4<\/strong>. To download the Roundcube file on a directory, use the commands:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">cd \/opt\nwget https:\/\/github.com\/roundcube\/roundcubemail\/releases\/download\/1.4.4\/roundcubemail-1.4.4-complete.tar.gz<\/pre>\n\n\n\n<p>Once downloaded, extract the archive then move the extracted directory to our preferred RoundCube Webmail installation directory:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">tar -xvf \/opt\/roundcubemail-1.4.4-complete.tar.gz\nmv \/opt\/roundcubemail-1.4.4 \/var\/www\/roundcube<\/pre>\n\n\n\n<p>Once the Roundcube Webmail files are in place, we need to apply for the correct file and directory permissions:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">chown -R apache:apache \/var\/www\/roundcube\n<\/pre>\n\n\n\n<p>Finally, we can now import Roundcube&#8217;s initial database set up which can be done using a MySQL command:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">mysql -u roundcube_user -p roundcube_db &lt; \/var\/www\/roundcube\/SQL\/mysql.initial.sql<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Step 5: Create Nginx VirtualHost<\/h2>\n\n\n\n<p>To access our Roundcube webmail installation on a subdomain, we need to set up a VirtualHost for the subdomain. To proceed, create an Nginx configuration file then copy the following content:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">nano \/etc\/nginx\/conf.d\/webmail.mydomain.com.conf<\/pre>\n\n\n\n<pre class=\"wp-block-preformatted\">server {\n  listen 80;\n  server_name webmail.mydomain.com;\n  root \/var\/www\/roundcube\/;\n  index index.php;\n\n  access_log \/var\/log\/nginx\/webmail.mydomain.com.access.log;\n  error_log \/var\/log\/nginx\/webmail.mydomain.com.error.log;\n\n  location \/ {\n    try_files $uri $uri\/ \/index.php?q=$uri&amp;$args;\n  }\n\n  location ~ \\.php$ {\n    include \/etc\/nginx\/fastcgi_params;\n    fastcgi_pass unix:\/run\/php-fpm\/www.sock;\n    fastcgi_index index.php;\n    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;\n  }\n}\n<\/pre>\n\n\n\n<p>Save the file, exit the text editor, then restart Nginx web server for the changes to take effect.<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">systemctl restart nginx<\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Step 6: Roundcube Initial Set-Up<\/h2>\n\n\n\n<p>Once Nginx is set up for our subdomain, we can now access the initial setup interface using our favorite browser. Simply browse the \/installer page e.g.<strong> http:\/\/webmail.mydomain.com\/installer<\/strong> and you should see the following initial set up page:<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.linuxcloudvps.com\/blog\/wp-content\/uploads\/2021\/05\/installing-roundcube-webmail-on-centos-8.png\"><img decoding=\"async\" width=\"789\" height=\"840\" src=\"https:\/\/www.linuxcloudvps.com\/blog\/wp-content\/uploads\/2021\/05\/installing-roundcube-webmail-on-centos-8.png\" alt=\"installing roundcube webmail on centos 8\" class=\"wp-image-1499\" srcset=\"https:\/\/www.linuxcloudvps.com\/blog\/wp-content\/uploads\/2021\/05\/installing-roundcube-webmail-on-centos-8.png 789w, https:\/\/www.linuxcloudvps.com\/blog\/wp-content\/uploads\/2021\/05\/installing-roundcube-webmail-on-centos-8-282x300.png 282w, https:\/\/www.linuxcloudvps.com\/blog\/wp-content\/uploads\/2021\/05\/installing-roundcube-webmail-on-centos-8-768x818.png 768w\" sizes=\"(max-width: 789px) 100vw, 789px\" \/><\/a><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.linuxcloudvps.com\/blog\/wp-content\/uploads\/2021\/05\/set-up-roundcube-webmail-on-centos-8.png\"><img decoding=\"async\" width=\"856\" height=\"766\" src=\"https:\/\/www.linuxcloudvps.com\/blog\/wp-content\/uploads\/2021\/05\/set-up-roundcube-webmail-on-centos-8.png\" alt=\"set up roundcube webmail on centos 8\" class=\"wp-image-1500\" srcset=\"https:\/\/www.linuxcloudvps.com\/blog\/wp-content\/uploads\/2021\/05\/set-up-roundcube-webmail-on-centos-8.png 856w, https:\/\/www.linuxcloudvps.com\/blog\/wp-content\/uploads\/2021\/05\/set-up-roundcube-webmail-on-centos-8-335x300.png 335w, https:\/\/www.linuxcloudvps.com\/blog\/wp-content\/uploads\/2021\/05\/set-up-roundcube-webmail-on-centos-8-768x687.png 768w\" sizes=\"(max-width: 856px) 100vw, 856px\" \/><\/a><\/figure>\n\n\n\n<p>If you can see that most parameters are OK, click <strong>NEXT<\/strong> to continue.
