ApacheHttpServers-server-status


Apache's http server's 'server-status' page help us a lot to dig more information about that http server.

At Ubuntu you can find this module at:

/etc/apache2/mods-available$ ls -l status*
-rw-r--r-- 1 root root 753 Feb  7  2012 status.conf
-rw-r--r-- 1 root root  64 Feb  7  2012 status.load

And you have to enable the same, type the following. 
[ NOTE: If you see this file under '/etc/apache2/mods-enabled' then no need to type the following command. ]

sudo /usr/sbin/a2enmod status

Then create a 'VirtualHost' to access the 'server-status' page:

<Location /server-status>
    SetHandler server-status
    Order deny,allow
    Deny from all
    Allow from localhost
</Location>

# You can do allow from the trusted network. 

After configuring, restart the http server.

then: Type the following at your web browser:

http://<YourWebServer>/server-status

Now, you will find the details about your web server.
