Apache’s newer version, 2.0, is necessary to take advantage of key features not available in older versions. Among them are:
- Multi-Process Modules (MPMs), which modify the way Apache listens to the network, accepts and handles requests to improve efficiency
- SNI (Server Name Indication), which allows multiple websites sharing a single IP address to each have their own SSL certificates installed
Checking the Apache Version from CLI
You can easily determine which version of Apache your server is running from the command line with:
Running that command will give you output that will look like this:
[root@host]# httpd -v
Server version: Apache/2.4.16 (Unix)
Server built: Dec 23 2015 11:28:39
Cpanel::Easy::Apache v3.32.6 rev9999
In this case, Server version shows that the server is running Apache 2.4.16.
Checking the Apache Version from WHM
You also can check the Apache version from WebHost Manager:
- In WHM’s left menu, locate the Server Status section and click on Apache Status. You can begin typing “Apache” in the search menu to quickly narrow the choices.
- The current Apache version will be displayed next to Server Version on the Apache Status page. In this case, it’s version 2.4.16.
