WordPress Basic Setup

20200902 Setting up a WordPress instance on Ubuntu is illustrated below using an Azure virtual machine running Ubuntu 20.04 LTS (myhub.australiacentral.cloudapp.azure.com). We begin by installing the wordpress software:

$ ssh myhub.australiaeast.cloudapp.azure.com
$ wajig update; wajig distupgrade
$ wajig install wordpress php libapache2-mod-php mysql-server php-mysql

The WordPress configuration file for Apache is then created:

$ sudo emacs /etc/apache2/sites-available/wordpress.conf
Alias /blog /usr/share/wordpress
<Directory /usr/share/wordpress>
    Options FollowSymLinks
    AllowOverride Limit Options FileInfo
    DirectoryIndex index.php
    Order allow,deny
    Allow from all
</Directory>
<Directory /usr/share/wordpress/wp-content>
    Options FollowSymLinks
    Order allow,deny
    Allow from all
</Directory>

We can then enable the WordPress module for Apache:

$ sudo a2ensite wordpress
$ sudo a2enmod rewrite
$ wajig reload apache2

WordPress uses MySQL to store its data, including users:

$ sudo mysql -u root
mysql> CREATE DATABASE wordpress;
mysql> CREATE USER 'wordpress'@'localhost' IDENTIFIED BY '<secret>';
mysql> GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpress'@'localhost';
mysql> FLUSH PRIVILEGES;
mysql> QUIT
$ wajig restart mysql

Configure the database information for WordPress to connect to it:

$ sudo emacs /etc/wordpress/config-localhost.php
<?php
define('DB_NAME', 'wordpress');
define('DB_USER', 'wordpress');
define('DB_PASSWORD', '<secret>');
define('DB_HOST', 'localhost');
define('DB_COLLATE', 'utf8_general_ci');
define('WP_CONTENT_DIR', '/usr/share/wordpress/wp-content');
?>

Now try it out.

$ firefox localhost/blog
Site Title: Kayon Institute
Username:   kayon
Password:   @6ClqvImsMsG1di$Yh
Email:      kayon@togaware.com
