Installing Apache Mysql and PHP using yum

I found this tutorial
http://www.flmnh.ufl.edu/linux/install_apache.htm

It tells me to use the yum command. When I use it it tells me there is another copy running



Could that be the updater?

Delete yum.pid

Thanks, works perfect now. Can you tell me what yum.pid does? I looked it up and people have said thats its just a bug.

I really don't know much about .pid files, myself. Apparently, the system has to be able to store the PIDs of the processes it creates. I would have to watch for changes in that directory to learn more about them. I don't know if I would call it a bug.

a PID is a process id. when you're in a terminal and enter the command: ps -e
it shows you the PID, TTY, time, and command (process name). so you could have entered ps -e | grep yum
and it would have showed you the process running for yum. you would then enter kill 6583 or whatever PID it told you yum had.

We know that but I have pid files that don't have a corresponding process running. The pid file must have been created and not removed when the process ended. Apparently, that's what happened to him.
