Automated Scripted Install of WordPress on CentOS7/RHEL7 Linux

Sometime ago, I wrote an automated script to install WordPress on a CentOS 5 install of Linux. Over the years, the repos and WordPress requirements changed as did CentOS upgrades through CentOS 6. The script was modified accordingly. The script had to be modified considerably for CentOS 7 which facilitates the need for a new article. Here is an automated install script for WordPress on a minimal install of CentOS7.

Basically, write the script as seen below, make it an executable with chmod +x install-wordpress-centos7.sh and run it. When done, go to your browser of choice and type in your IP address. Done. You’ll be up and running in a matter of minutes.

#!/bin/bash
# install-wordpress-centos7.sh
#
# Description: This script will download, configure and install WordPress for CentOS/RHEL 7.x Linux.
#
cd /opt

# Open firewall ports
firewall-cmd --permanent --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=https
firewall-cmd --reload

# Install the database
yum -y install mariadb-server httpd php php-mysql
systemctl enable mariadb.service
systemctl start mariadb.service

# Add to the database
echo 'CREATE DATABASE wordpress;' | mysql
echo "GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpress'@'localhost' IDENTIFIED BY 'password';" | mysql
echo "FLUSH PRIVILEGES;" | mysql

# Download and install WordPress
curl -O https://wordpress.org/latest.tar.gz
tar -C /var/www/html/ --strip-components=1 -zxvf latest.tar.gz &amp;&amp; rm -f latest.tar.gz
cd /var/www/html
mkdir wp-content/{uploads,cache}
chown apache:apache wp-content/{uploads,cache}

# Configure WordPress
cp wp-config-sample.php wp-config.php
sed -i 's@database_name_here@wordpress@' wp-config.php
sed -i 's@username_here@wordpress@' wp-config.php
sed -i 's@password_here@password@' wp-config.php
curl https://api.wordpress.org/secret-key/1.1/salt/ &gt;&gt; wp-config.php

# Modify the .htaccess
echo "# BEGIN WordPress
&lt;IfModule mod_rewrite.c&gt;
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
&lt;/IfModule&gt;
# END WordPress" &gt;&gt; .htaccess
chmod 666 /var/www/html/.htaccess

# Configure and start Apache
sed -i "/^&lt;Directory \"\/var\/www\/html\"&gt;/,/^&lt;\/Directory&gt;/{s/AllowOverride None/AllowOverride All/g}" /etc/httpd/conf/httpd.conf
systemctl enable httpd.service
systemctl start httpd.service

Just a quick note. This is a “quick” and dirty approach to simply get WordPress up and running in a matter of minutes. Changing of the usernames, passwords, and tables prefixes would be wise in a production environment. Also hardening the database would be prudent.
