WordPress installation on Centos/RHEL 7

Last updated on March 12th, 2018 at 08:55 pm

WordPress is a free & open source website/blogging tool, it’s based on MySQL & php. Currently it powers around 27% websites available on internet. Its ease of use makes it a perfect choice for beginners as well as expert bloggers. WordPress supports a large number of plugins & themes, which enhances its usability & customization. Also there is huge community of dedicated wordpress users out there that are always willing & able to provide support as & when needed.

In this tutorial, we are going to install wordpress on Centos 7 but same tutorial can be used with earlier versions of RHEL/Centos also.

Pre-requisites

1- We will need a LAMP server to install wordpress on. Kindly refer to our article on creating a LAMP server to create one. Once the LAMP server is ready, we can move on with this tutorial.

2- Apart from the php modules installed during the installation of LAMP server, we also need php-gd installed on our system. We can install by using following command,

$ yum install php-gd

Restart the httpd service to implement the changes.

$ systemctl restart httpd

 

Step 1- Configuring MySQL

We need to create a database for our wordpress website. To create the database, login to the MySQL server,

$ mysql -u root -p

and create a database table for wordpress,

$ CREATE DATABASE wordpressdb;

Once the database has been created, we will assign a user with complete access to the created database i.e. ‘wordpressdb’,

$ GRANT ALL PRIVILEGES ON wordpressdb.* TO ‘wpuser’@’localhost’ IDENTIFIED BY ‘wppasswd’;

To make Mysql aware of the recent privilege changes, we will run the following command,

FLUSH PRIVILEGES;

The changes on Mysql are complete, we can now exit the Mysql.

 

Step 2 – Installing WordPress

We can now install wordpress on our system, the latest of the wordpress version is always available on the same link. To install download wordpress, run

$ wget http://wordpress.org/latest.tar.gz

then, extract the package,

$ tar -xvf latest.tar.gz

After the package has been extracted, there will be an extracted folder called ‘wordpress’. We need to move this folder in /var/www/html,

$ mv -vf wordpress /var/www/html

We will now assign the proper permissions i.e. grant ownership of all content inside /var/www/html to apache user,

$ chown -R apache:apache /var/www/html/*

 

Step 3 – Configuring wordpress

We will now edit the wordpress configuration file i.e. wp-config.php but by default there is no file by that name under /var/www/html/wordpress. But we can use a sample configuration file that is already inside the wordpress folder, by renaming it to wp-config.php,

$ cd /var/www/html

$ mv wp-config-sample.php wp-config.php

We will now provide our database information inside the configuration file,

$ vi wp-config.php

& make the following changes,

// ** MySQL settings – You can get this info from your web host ** //

/** The name of the database for WordPress */

define(‘DB_NAME’, ‘wordpressdb’);

/** MySQL database username */

define(‘DB_USER’, ‘wpuseruser’);

/** MySQL database password */

define(‘DB_PASSWORD’, ‘wppasswd‘);

We have now completed our installation & partial configuration of wordpress, but we have still not hosted the website & remaining configurations for the website will be carried out from the browser.
So open your browser & enter the URL

$ http://localhost/wordpress

You will now be asked to provide your site title, user name, password & email account.
Wordpress installation

After entering all the information, press ‘install WordPress’ button.You will now get a confirmation with success message.
wordpress installation
Now to login to the wordpress dashboard, click ‘Log in’ button & you will be redirected to a new page where you need to enter your username & password.
wordpress installation
Upon successful authentication, we will enter to wordpress dashboard. Here we can customize our website with plugins & themes, we can also upload posts, articles etc

Note:- if you don’t want to have ‘wordpress’ at the end of the URL, you can move all the contents of /var/www/html/wordpress to /var/www/htm & restart the httpd service to implement changes.We can now access our website with just the IP address or the hostname of the server.
