Complete!

Next, We have to start apache and mariadb services

[root@linuxhelp ~]# systemctl start mariadb httpd

Then secure the mysql server using following steps

[root@linuxhelp ~]# mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] 
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] 
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] 
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

Now, log in the mysql and create the essentials

[root@linuxhelp ~]# mysql -u root -p
Enter password: 
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 10

Bye

Next, Download the webtatic repo

[root@linuxhelp ~]# wget https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

Then, install the downloaded repo

[root@linuxhelp ~]# rpm -Uvh webtatic-release.rpm 
warning: webtatic-release.rpm: Header V4 RSA/SHA1 Signature, key ID 62e74ca5: NOKEY

Same as above download and install the remi-release repo

[root@linuxhelp ~]# wget http://rpms.remirepo.net/enterprise/remi-release-7.rpm

Now, we have to enable the php-version 7.2 in remi repo using the following command

[root@linuxhelp ~]# yum-config-manager --enable remi-php72
Loaded plugins: langpacks, product-id, subscription-manager
This system is not registered with an entitlement server. You can use subscription-manager to register.

baseurl =

…
…
ui_id = remi-php72
ui_repoid_vars = releasever,
   basearch

After, we can install the php and its module

[root@linuxhelp ~]# yum install php php-gd php-pdo php-mbstring php-mcrypt php-mysql php-simplexml php-pecl-zip php-imap -y
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager

Make directory for joomla under www

[root@linuxhelp ~]# mkdir /var/www/joomla

Change directory to joomla

[root@linuxhelp ~]# cd /var/www/joomla/

Here, we have download the joomla cms

[root@linuxhelp joomla]# wget https://downloads.joomla.org/cms/joomla3/3-9-4/Joomla_3-9-4-Stable-Full_Package.zip?format=zip

The downloaded joomla cms is not in zip file

[root@linuxhelp joomla]# ll
total 13548
-rw-r--r--. 1 root root 13869429 Mar 11  2019 Joomla_3-9-4-Stable-Full_Package.zip?format=zip

So, I convert the file into zip file using the below command

[root@linuxhelp joomla]# mv Joomla_3-9-4-Stable-Full_Package.zip?format=zip Joomla_3-9-4-Stable-Full_Package.zip

Then, unzip the joomla zip file

[root@linuxhelp joomla]# unzip Joomla_3-9-4-Stable-Full_Package.zip

….    

Now, we have to change the ownership and permission for the joomla directory

[root@linuxhelp www]# chmod –R 775 joomla/
[root@linuxhelp www]# chown -R apache. joomla/

Create virtual host to access our website from the browser

[root@linuxhelp www]# vim /etc/httpd/conf.d/joomla.conf
<virtualhost  *:80>
Servername www.linuxhelp1.com
Document root  /var/www/joomla/
<directory /var/www/joomla/>
Allowoverride all
Allow from all
</directory>
</virtualhost>

Configure the hosts file with the following information

[root@linuxhelp www]# vim /etc/hosts
<provide your host ip>    <your-domainname>

After the configuration we need to restart the Apache service

[root@linuxhelp www]# systemctl restart httpd

Once the installation is completed from the browser, at the end of the installation there will be configuration.php content Copy the content then create the file named as configuration.php under /var/www/joomla with this content

[root@linuxhelp joomla]# vim  configuration.php

Paste the content in this file.

Open Browser and type the domain name in the search bar Configure the Main configuration Here, give mysql user credentials Overview the configuration then click on Install

After the installation Remove the Installation folder

With this, the method to install Joomla CMS on RHEL7.6 comes to end.
