How to rename a wordpress site from http://myserver.example.com/blog to http://myserver.example.com/somethingelse or just http://myserver.example.com

Those instructions are a little odd to my eye.

I think you’re being forced to use /blog because of Step 3 in the instructions. The Apache directive

Alias /blog /usr/share/wordpress

…directs Apache to route any requests to /blog to the directory where you’ve installed WordPress. (See Apache’s docs on the Alias directive.)

I don’t know for sure that you’ll be able to set your site’s root URL (/) to load WordPress, but you should easily be able to use /someotherurl instead. Just modify the /etc/apache2/sites-available/wordpress.conf file and change

Alias /blog /usr/share/wordpress

to

Alias /someotherurl /usr/share/wordpress

You’ll need to reload the Apache service for this to take effect, using sudo service apache2 reload as stated at the end of Step 3.
