About WordPress

WordPress is an online, open source website creation tool written in PHP. But in non-geek speak, it’s probably the easiest and most powerful blogging and website content management system (or CMS) in existence today.

Set up

* Before working with wordpress, you need to have LAMP installed on your server.

* Once you have the user and required software, you can start installing wordpress.

Steps for installing and configuring wordpress in cent OS 6 as below

Step 1 : 

Download wordpress

We can download WordPress using the below command

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

This command will download the zipped wordpress package straight to your user’s home directory.

Unzip wordpress package

We can unzip it to the next line

tar -xzvf latest.tar.gz

Step 2 : 

Creating wordPress Database and User

After we unzip the wordpress files, they will be in a directory called wordpress in the home directory.

Now we need to switch gears for a moment and create a new MySQL directory for wordpress.

Log into the MySQL Shell:

mysql -u root -p

* Login using your MySQL root password

Then we need to create

*  Wordpress database
*  User in that database and
*  Give that user a new password.

Note : All MySQL commands must end with semi-colon

CREATE DATABASE wordpress;
Query OK, 1 row affected (0.00 sec)

* Then we need to create the new user.
* We can replace the database, name and password with our preference

CREATE USER wordpressuser@localhost;
Query OK, 0 rows affected (0.00 sec)

Set the password for the new user:

SET PASSWORD FOR wordpressuser@localhost= PASSWORD("password");
Query OK, 0 rows affected (0.00 sec)

Upon the process we have to grant all the privileges on wordpress

GRANT ALL PRIVILEGES ON wordpress.* TO wordpressuser@localhost IDENTIFIED BY 'password';
Query OK, 0 rows affected (0.00 sec)

Then refresh MySQL:

FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

Exit out of the MySQL shell:

exit

Step 3 : 

WordPress configuration setup

The first step to is to copy the sample wordpress configuration file located in the wordpress directory into a new file which we will edit, creating a new usable wordpress config

cp ~/wordpress/wp-config-sample.php ~/wordpress/wp-config.php

Then open the wordpress config:

vi ~/wordpress/wp-config.php

Find the section that contains the field below and substitute in the correct name for your database, username, and password:

// ** MySQL settings - You can get this info from your web host ** //
/** The name of the database for WordPress */
define('DB_NAME', 'wordpress');

/** MySQL database username */
define('DB_USER', 'wordpressuser');

/** MySQL database password */
define('DB_PASSWORD', 'password');

Save and Exit.

Step 4 : 

Copy the files

The final move that remains is to transfer the unzipped WordPress files to the website’s root directory.

sudo cp -r ~/wordpress/* /var/www/html

From here, WordPress has its own easy to follow installation form online.

However, the form does require a specific php module to run. If it is not yet installed on your server, download php-gd:

sudo yum install php-gd

Last of all restart Apache:

sudo service httpd restart

Step 5 : 

Access the WordPress Installation

Upon completion of above process we can access the wordpress admin page as below

domainname.com/wpadmin 

Click continue and proceed further for the installation setup
