One of the many strengths of Linux is its powerful shell. With the Bash scripting language, you can automate repetitive tasks and set up software with just a few clicks. This guide will walk you through creating a bash script to set up WordPress, a popular content management system, on Ubuntu.
Guide to Creating a Bash Script to Install WordPress on Ubuntu
Pre-requisites
- Ubuntu Server (The latest LTS version is recommended).
- Root or sudo privileges.
Step 1: Update Your Server
First, you’ll need to make sure your Ubuntu server is up-to-date. Here’s a simple command to update and upgrade your system packages:
sudo apt-get update && sudo apt-get upgrade -y
Step 2: Install LAMP Stack
WordPress needs a web server, a database, and PHP to function correctly. These are provided by the LAMP (Linux, Apache, MySQL, PHP) stack. Use this command to install the LAMP stack:
sudo apt-get install apache2 mysql-server php php-mysql libapache2-mod-php php-cli -y
Step 3: Download and Install WordPress
Now, you can download and extract WordPress from the official source:
wget https://wordpress.org/latest.tar.gz
tar -xvf latest.tar.gz
Move the WordPress files to the Apache web directory:
sudo mv wordpress /var/www/wptbox/
Step 4: Configure WordPress
Before you can use WordPress, you’ll need to create a database and configure the wp-config.php file.
mysql -u root -p -e "CREATE DATABASE wordpress_db; CREATE USER 'wordpress_user'@'localhost' IDENTIFIED BY 'password'; GRANT ALL PRIVILEGES ON wordpress_db.* TO 'wordpress_user'@'localhost'; FLUSH PRIVILEGES;"
This creates a new database (wordpress_db) and a new user (wordpress_user) with the password password. You should replace password with a secure password of your choice.
You’ll also need to copy the default WordPress configuration file and fill in your database details:
cd /var/www/wptbox/wordpress
cp wp-config-sample.php wp-config.php
sed -i 's/database_name_here/wordpress_db/g' wp-config.php
sed -i 's/username_here/wordpress_user/g' wp-config.php
sed -i 's/password_here/password/g' wp-config.php
Step 5: Finalize the Installation
Finally, you need to change ownership of the WordPress files and restart Apache to reflect the changes:
sudo chown -R www-data:www-data /var/www/wptbox/wordpress
sudo systemctl restart apache2
Now you can open a web browser and navigate to your server’s IP address to complete the WordPress installation through its web interface.
Complete BASH Script to Configure WordPress on Ubuntu
Let’s combine all of these commands into a single bash script. Save this script as wordpress_install.sh and run it with sudo bash wordpress_install.sh.
#!/bin/bash
# Step 1: Update Server
sudo apt-get update && sudo apt-get upgrade -y
# Step 2: Install LAMP Stack
sudo apt-get install apache2 mysql-server php php-mysql libapache2-mod-php php-cli -y
# Step 3: Download and Install WordPress
wget https://wordpress.org/latest.tar.gz
tar -xvf latest.tar.gz
sudo mv wordpress /var/www/wptbox/
# Step 4: Configure WordPress
mysql -u root -p -e "CREATE DATABASE wordpress_db; CREATE USER 'wordpress_user'@'localhost' IDENTIFIED BY 'password'; GRANT ALL PRIVILEGES ON wordpress_db.* TO 'wordpress_user'@'localhost'; FLUSH PRIVILEGES;"
cd /var/www/wptbox/wordpress
cp wp-config-sample.php wp-config.php
sed -i 's/database_name_here/wordpress_db/g' wp-config.php
sed -i 's/username_here/wordpress_user/g' wp-config.php
sed -i 's/password_here/password/g' wp-config.php
# Step 5: Finalize the Installation
sudo chown -R www-data:www-data /var/www/wptbox/wordpress
sudo systemctl restart apache2
Remember to replace ‘password’ with your secure password.
That’s it! You’ve just written a bash script to automate the setup of WordPress on Ubuntu.
