        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.

                    @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.
