Install Roundcube Webmail on CentOS 7

Step 1. First, let’s start by ensuring your system is up-to-date.

yum clean all
yum -y update

Step 2. Install the LAMP server.

A CentOS 7 LAMP stack server is required. If you do not have LAMP installed, you can follow our guide here. Also, install the required PHP modules:

yum install php-json php-xml php-mbstring php-imap php-pear-DB php-mysql -y

Step 3. Installing Roundcube Webmail.

The first thing to do is to go to Roundcube’s download page and download the latest stable version of Roundcube, At the moment of writing this article it is version 1.1.4:


Unpack the Roundcube archive to the document root directory on your server:

tar -zxpvf roundcubemail-1.1.4-complete.tar.gz -C /var/www/html/
mv roundcubemail-1.1.3 roundcube

We will need to change some folders permissions:

chown apache:apache -R /var/www/html/roundcube

Step 4. Configuring MariaDB for Roundcube Webmail.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. You should read and below each step carefully which will set a root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB.


Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

Next, we will need to log in to the MariaDB console and create a database for the Roundcube Webmail. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for Roundcube Webmail installation:

MariaDB [(none)]> CREATE DATABASE roundcubemail /*!40101 CHARACTER SET utf8 COLLATE utf8_general_ci */;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON roundcubemail.* TO roundcube@localhost IDENTIFIED BY 'password';
MariaDB [(none)]> \q

Step 5. Start Roundcube installation using a web browser installer.

Roundcube Webmail will be available on HTTP port 80 by default. Open your favorite browser and navigate to or http://server-ip-address/roundcube/installer and complete the required steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.

After installation is complete Remove the installer directory from your web server document root (/var/www/html/roundcube):

cd /var/www/html/roundcube/
rm -rf installer

Now access your account using Roundcube, Navigate to and log in using your email account’s username and password. If your configuration is functional, Roundcube will allow you to receive, read and send emails from inside and outside of your domain name.
