Linux – the difference between Apache Web Server and Apache HTTPD

apache-http-serverhttpdlinux

I am doing some application monitoring and my requirement is to see what differentiates an Apache Web Server and Apache HTTPD. I know Apache Web Server is a "server" and Apache httpd is a "program".

I need to run both on Linux. Is there any difference in the executable file name or full command line or package name for the two?

Is there any difference in way of deployments?

I have searched online but everywhere Apache Web server and HTTPD are used interchangeably.

Best Answer

No difference whatsoever. HTTPD is a program that is (essentially) a program known as Apache Web server.

The only difference I can think of is that on Ubuntu/Debian the binary is called apache2 instead of httpd which is generally what it is referred to as on RedHat/CentOS.

Functionally they are both 100% the same thing.
