How to Install WordPress Blog on CentOS 5.5

WordPress, a renowned Content Management System (CMS), is a robust open-source blogging tool and publishing platform powered by PHP and MySQL. It can be installed on both Windows and Linux servers, offering a plethora of features, including plugins that modernize and empower your blog.

This guide will walk you through the process of installing WordPress on a CentOS server, assuming you have already set up a LAMP (Linux, Apache, MySQL, and PHP) server. For more information on different server types, you can explore our articles on Apache, Nginx, and LiteSpeed.

Step 1: Access Your Web Server Root Directory

Start by navigating to your web server root directory. You can do this by entering the following command:

cd /var/www

Step 2: Download the Latest WordPress

Next, download the latest version of WordPress using the wget command:

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

Step 3: Extract the Compressed Archives

After downloading WordPress, you need to extract the compressed archives with the following command:

tar xzvf latest.tar.gz

Step 4: Rename the Extracted File

The extracted file will be named ‘wordpress’. You can rename it to anything you want. For the purpose of this tutorial, we will rename it to ‘blog’:

cp wordpress blog

Your URL will now look like this: http://servername/blog

Step 5: Create the Database and Database User

Next, create the database and database user. You can do this by entering the following commands:

CREATE DATABASE blogdb;
CREATE USER 'bloguser'@'localhost' IDENTIFIED BY 'blogpassword';
GRANT ALL PRIVILEGES ON blogdb.* to bloguser@localhost;

Step 6: Navigate to Your Blog URL

Now, navigate your browser to http://servername/blog. You will be prompted to create a wp-config.php file. Click on “Create a Configuration File”.

Step 7: Setup Configuration File

You will be redirected to the WordPress Setup Configuration File page. Here, you will need to provide some information on the database. Fill in the details as per the database and user you created in Step 5. If your Apache and MySQL are on the same server, your Database host will be ‘localhost’.

Click on “Let’s Go!” to proceed.

Step 8: Fill in the Form and Submit

Fill in the form with the following details and click Submit:

Database name = blogdb
Database username = bloguser
Database password = blogpassword
Database host = localhost
Table prefix = wp_

You will be redirected to a page where you will be asked to manually create the wp-config.php file.

Step 9: Create the wp-config.php File

To create the wp-config.php file, go back to your web server terminal or SSH to your web server. Copy and rename wp-config-sample.php to wp-config.php using the following command:

cp /var/www/blog/wp-config-sample.php /var/www/blog/wp-config.php

Step 10: Modify the wp-config.php File

Next, you need to modify the wp-config.php file. Open the file using the vi editor:

vi /var/www/blog/wp-config.php

Change the following lines to match the database details you set up earlier:

/** The name of the database for WordPress = Line 19 */
define('DB_NAME', 'blogdb');

/** MySQL database username = Line 22 */
define('DB_USER', 'bloguser');

/** MySQL database password = Line 25 */
define('DB_PASSWORD', 'blogpassword');

/** MySQL hostname = Line 28 */
define('DB_HOST', 'localhost');

Save the wp-config.php file and exit from the web server.
