Apache Installed

Lakshmana

@scottalanmiller I have installed the apache server in the machine and checked the loopback address in the browser and after that the nginx is installed but not configured properly.
I need to check the status of the apache by deleting any files in the apache file and other things to test in the web browser

Well yes, you can only have one and whichever one you start first will be the only one you can see. The other cannot start with the first one is there. Pick the one that you want and remove the other.

I'm unclear what you want to test. Apache by default has one page and it shows it. You can delete it, but then there is nothing to show. Web servers are very basic, there is very little to test.

@scottalanmiller For the purpose of interview i need to check the process in the apache servers.

You don't do that as you describe. Use the ps command to check on the process. Use the netstat command to see if it is listening.

For netstat, use these options for best results...

netstat -tulpn

Is Nginx still running? If not, was httpd restarted after it was removed?

@Lakshmana please post the output of

assuming you want to run on port 80. Please also post the output of

~~ps ax | grep -v grep | grep -E 'apache|httpd'~~

OK, not required anymore. About the error: ps ax, not ps -ax, my bad

Looks like you are forgetting to be root when doing systems administration tasks. Switch to root before doing any of this.

thwr

netstat -an | grep -i tcp | grep -i listening | grep 80

ps ax | grep -v grep | grep -E 'apache|httpd'

again, my bad. Could be your grep doesn't support -E, just use

ps ax | grep -v grep | grep apache

ps ax | grep -v grep | grep httpd

instead.
