On my Mac, I modified the VirtualHost:
<VirtualHost *:80>
DocumentRoot "/Users/me/Documents/github/gps_cms"
ServerName gps_cms
</VirtualHost>
That is so I can type gps_cms in URL and invoke the web page on localhost.
However, when I type in:
http://gps_cms/wp-admin
It redirects to my main site:
http://example.com/wp-admin/upgrade.php?_wp_http_referer=%2Fwp-admin%2F
And the content on page is this:
No Update Required
Your WordPress database is already up-to-date!
WordPress will try to redirect you to the canonical URL for the site, as set in the database during the initial install. But you can override it in the
wp-config.phpfile by setting theWP_HOMEconstant:http://codex.wordpress.org/Editing_wp-config.php#Blog_address_.28URL.29
If WP is installed in a subdirectory, you might also need to set
WP_SITEURL.
