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:

[root@joomla-server ~]# yum update -y

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

[root@joomla-server ~]# 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

[root@joomla-server ~]# systemctl start httpd ; systemctl enable httpd
[root@joomla-server ~]# 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

[root@joomla-server ~]# 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 “Joomla@123#“, you can provide your own names and password

[root@joomla-server ~]# mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.

[root@joomla-server ~]#

Download and Install Joomla

Once your done with Database creation for Joomla, Now lets download latest version of Joomla from its Official Web site.


In my case i am downloading the Joomla software from the command line using wget command.

[root@joomla-server ~]# wget

Extract the file into the Apache root directory (/var/www/html)

[root@joomla-server ~]# unzip -d /var/www/html/

Assign proper permissions to the apache root directory and sub-directories using the beneath commands

[root@joomla-server ~]# chown -R apache:apache /var/www/html/
[root@joomla-server ~]# chmod -R 775 /var/www/html/

Edit the Apache web sever configuration file (/etc/httpd/conf/httpd.conf) and change the following line as described below

Change the line from:

AllowOverride None to AllowOverride All

Now make sure to save the httpd.conf file and restart the Apache Service

[root@joomla-server ~]# systemctl restart httpd

Configure Firewall

In case OS firewall enabled on your server then provide access to port 80 and 443 to be accessed from outside the network with the command below:

[root@joomla-server ~]# firewall-cmd --permanent --add-service=http

root@joomla-server ~]# firewall-cmd --permanent --add-service=https

Reload the firewall services for the changes to take effect

[root@joomla-server ~]# firewall-cmd --reload

Configure Joomla

So, everything is setup, you’ve successfully installed LAMP, created a database, downloaded and installed Joomla, and also configured the firewall and now it’s time to open your browser and configure Joomla using the Joomla installation wizard:

Now open your browser and provide the following URL


Make sure to provide the IP of your system IP in the [your-server-ip]

You can see the following webpage and provide all the information required in the screen including your website name, email, username and password. Also, select the preferred language accordingly. Once you’ve provided all the details, Click ‘Next’ to proceed.


Now it’s time to provide all the needed information for your database including your database name, database user name, database password, table prefix (say for example, if you give a prefix as “ltx”, all your tables with start as “ltx_tablename”)


Leave the FTP details as it is and click on Next.


Last step is to overview all data provided and Click on “Install” button to start the installation process.


Once the installation is completed, we will get the next window something like below:


We will see a message to copy the content provided below and save the file as configuration.php in your  Apache root directory, Copy this content and paste in configuration.php

[root@joomla-server ~]# vi /var/www/html/configuration.php
class JConfig {
    public $offline = '0';
    public $offline_message = 'This site is down for maintenance.<br />Please check back again soon.';

Now save the file and remove the installation folder manually.

[root@joomla-server ~]# rm -rf /var/www/html/installation/

[root@joomla-server ~]# chcon -R -t httpd_sys_rw_content_t /var/www/html/
