Install a Basic WordPress Site with WP-CLI
WP-CLI is an open source command line for WordPress. Here we will demonstrate a very basic install of WordPress assuming that we have a working web server and PHP stack with MariaDB or MySQL already installed. And assuming that you have installed WP-CLI and have it in your path as wp.
First change directory into your default web directory:
In my example I am using CentOS, RHEL or Fedora. But the idea is the same regardless. Now we need to download the WordPress files.
wp core download
Once downloaded, we need to make a wp-config.php file, which we can do by copying the wp-config.php.sample file and filling in our credentials for our database server. We need only the server name (normally just localhost) and a username and password that have been set up with access to create databases on our server. You can specify here a dedicated database name (not yet created) or one that is already created and specify an unused prefix OR.... we can do this with WP as well...
wp core config --dbname=databasename --dbuser=databaseuser --dbpass=databasepassword --dbhost=localhost --dbprefix=prfx_ wp db create
This command takes the details in the wp-config.php file and creates the database that we need based on the specifications there. If you are doing this multiple times with a single database, most of these details can simply be copied from another installation.
Once the database is ready, we are free to set up our site:
wp core install --url=mysite.mydomain.com --title="My Cool Site" --admin_user="admin" --admin_email="[email protected]"
That's it. Your site should be up and running assuming that your infrastructure is ready for it. A very simplistic example, but just three commands from blank LAMP (or similar server) to working WordPress install.
