If you need to check the Apache version number installed on your server, you can do so in one of a couple of ways.

From WHM / Cpanel 

  1. Login to WHM
  2. Type apache in the search bar and open up the Apache Status screen. The current Apache version will be displayed next to Server Version on the Apache Status page.

Using the Command Line

  1. First, log in to your server as the root user.
  2. Next, enter the following command:

    root@host[~]# /usr/local/apache/bin/httpd -v

    Or simply:

    root@host[~]# httpd -v
