Find the Process run by nohup command

I run a server executable in Centos using the following command "nohup server &". Now I need to kill the process "server". But I tried "ps -a" command to get the PID but I couldnt get the process. Now how to kill the "server" now?

If a nohup.out file was created, you may run in bash:

# lsof nohup.out

it will return the pid which created/is running the file

ps auxwww|grep -i 'server' should return all process which has server in them. Otherwise, server may have already stopped.

You should be able to determine the PID (and store it in a file) as follows:

nohup server &
print $! >> my_server.pid

The best way to launch a server in centos is with the service command.

So service httpd start

There is a chance that you want to write your program as a daemon

A daemon (or service) is a background process that is designed to run autonomously,with little or not user intervention. The Apache web server http daemon (httpd) is one such example of a daemon. It waits in the background listening on specific ports, and serves up pages or processes scripts, based on the type of request.

There is no definitive way to catch the exact process with the help of ps command, but you can use the following:

ps -a | grep "server"

You will get a list of all the processes running with the name "server"

Or, you can use any other keywords as well to grep the ps output.
