      @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.

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

                  @Lakshmana please post the output of

                  netstat -anp tcp | grep listening | grep 80

                  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.

                          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.

                              Okay, so at this point, httpd is definitely running.
