This tutorial will explain how to install latest version Joomla 3.7.2 on CentOS 7 / RHEL 7, now let’s jump in directly to the tutorial:

Technical Requirements

  • A server running on CentOS 7  / RHEL 7
  • LAMP stack which includes Apache (2.x+), PHP (5.3.10+)  and MySQL / MariaDB (5.1+)

Install LAMP Stack

If you have LAMP installed in your system, you can skip this, but if you don’t you’ll need to follow these steps to have LAMP installed in order to have Joomla in your system:

Update your CentOS / RHEL  system using the command below:

[[email protected] ~]# yum update -y

Now Install Apache Web server and MariaDB database  and PHP with the command below:

[[email protected] ~]# yum install httpd mariadb-server php php-mysql php-curl php-gd php-pear php-memcache php-pspell php-snmp php-xmlrpc -y

Once the LAMP stack packages are installed then start and enanle httpd and mariadb  services

[[email protected] ~]# systemctl start httpd ; systemctl enable httpd
[[email protected] ~]# systemctl start mariadb ; systemctl enable mariadb

Configure MariaDB Database for Joomla

Run the command “mysql_secure_installation” to configure password for root user, to remove anonymous-user accounts and to remove test database which is accessed by anonymous users

[[email protected] ~]# mysql_secure_installation

Set a strong and secure password and answer the questions below as provided:

Set root password? [Y/n] New password:  <New_Strong_Password>
Re-enter new password: <New_Strong_Password>
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

Now login to the database using root user credentials that we set in above command.

Create a database, user and grant privileges to the user, Let’s call the database as “joomldb” and username as “dbuser” and set password as “[email protected]#“, you can provide your own names and password

[[email protected] ~]# mysql -u root -p
Enter password:

Change the line from:
