Change domain name

Scenario: the site at old.name.org is to be changed to new.name.org .

Step 1: Wordpress config

Code Block
mv /etc/wordpress/conf-old.name.org.php /etc/wordpress/conf-new.name.org.php

Step 2: Wordpress DB

The connection parameters can be found in {{/etc/wordpress/conf-new.name.org.php}} :

Code Block
mysql -u user_name -h localhost --password=secret db_name << EOF
UPDATE wp_options SET option_value = 'http://new.name.org' WHERE option_name = 'home' OR option_name = 'siteurl';
EOF

Step 3: nginx config

Nginx can instruct browsers to use the new domain name, add this snippet in /etc/nginx/sites-available/wordpress_site_config_file

Code Block
server {
    server_name old.name.org;
    rewrite ^ $scheme://new.name.org$request_uri permanent;
}

And, change the {{server_name}} attribute in the main server  block to: new.name.org.

Step 4: Nginx frontend (web2)

Add new.name.org (and eventually {{*.new.name.org}}) to the server_name attribute in the relevant file in web2:/etc/nginx/sites-enabled/.
