Deploying WordPress on CentOS, Part 1: The Manual Method

3. Configure Services
   Now that we have the required packages for MySQL, let’s configure the internal database we will use. If you already have an external MySQL cluster, you can utilize that but remember to open the appropriate ports for communication.

Start Apache and MySQL

sudo systemctl start httpd mariadb

Enable Services at Startup

sudo systemctl enable httpd mariadb

Enable Firewall Rules

sudo firewall-cmd --add-service=http
sudo firewall-cmd --add-service=https
sudo firewall-cmd --runtime-to-permanent

Secure MySQL

mysql_secure_installation

At this stage, we will be prompted for information to secure the installed MySQL database. Recommended actions are to answer yes to everything. (Default root password is none, so just hit Return)

4. Configure MySQL
   Next, let’s setup our database that we will be using with WordPress.

Login to database with Password configured in Step 3

mysql –u root -p

Once at the MySQL prompt, create the database and user

CREATE DATABASE yourdatabasenamehere;
GRANT ALL ON yourdatabasenamehere.* TO wordpressdbuser@localhost IDENTIFIED BY "wordpressdbpass";
FLUSH PRIVILEGES;
EXIT

5. Installing WordPress
   Great, database is done! Now we’re going to install the latest build of WordPress.

Install wget, Export Files to Root Apache (or path of choice)

sudo yum -y install wget
wget http://wordpress.org/latest.tar.gz
tar xfz latest.tar.gz 
sudo cp -rf wordpress/* /var/www/html/
sudo rm -rf wordpress
ls /var/www/html/

Modify Site Files

cd /var/www/html/
sudo cp wp-config-sample.php wp-config.php
sudo vi wp-config.php

Once you have the wp-config.php open in your editor, enter the information we generated in Step 4.
–DB_NAME
–DB_USER
–DB_PASSWORD
–DB_HOST (If Different)

When completed, do a :wq!

Perfect! You have now successfully finished installing WordPress. If you navigate to your webpage, it should redirect you to the initial configuration page. http://<url>/wp-admin/install.php. It’s a good idea to check the box discouraging search engines from indexing your page until everything is configured the way you’d like.

Optionally, you can install myphpadmin to manage the mysql database from a UI. Be sure to allow your IP address in the phpMyAdmin.conf. Once configured, navigate to http://<url>/phpmyadmin and configure your credentials for access.

Install phpmyadmin and configure

sudo yum -y install phpMyAdmin
sudo vi /etc/httpd/conf.d/phpMyAdmin.conf
sudo systemctl restart httpd.service

Navigate to the next page to configure SSL and HTTPS redirects.
