WordPress Install Script

By November 30, 2014 Tutorial No Comments

I have written a little script to make it easy to create new WordPress sites on a LEMP stack.

You can fin the source file here: wpinstall.sh

#!/bin/bash -e

This script is really easy to use, the first step is to create the directory where we want to install wordpress.

mkdir /usr/share/nginx/www/mywebsite.com

Please note that the folder name is important as it will be use in the script later.

Then you will need to download the script file, you can either download it from Github (link above) or just copy the an paste it in a file named wpinstall.sh

chmod 744 wpinstall.sh

We change the permissions on the files so we can execute the script.


This command will start the installation script, you will have to provide some information for the script to be able to generate the different configuration files.

First the url of the website (www.mywebsite.com), you will have to use this type of urls otherwise the script won’t work. There is no need to add http:// in front of the url but don’t forget the www. Also mywebsite.com should correspond to the name of the directory where you are installing the website.

Then the script will ask for database name, database user and database password, it will be used to create a new database for our WordPress installation. You will also be prompted to enter your MySQL root password, just type your password and press enter.

Once all details are entered the script will download the latest version of WordPress and update the wp-config.php file as well as a few permissions.

You should now be all good to go, just update wp-config.php with your secret keys and your new WordPress site is up and running…
