To find out which version of apache you have installed in your dedicated server, run the following command:
Code:httpd -v
After you have executed the command above, you should see a message from the shell that looks similar to the one below:
Code:Server Version: Apache/2.0.54
Server built: May 23 2005 08:12:24
In my example above, I have Apache 2.0.54 installed on my server.
Hope this helps
