Hi, I need to know if mysql and apache -for example- are running, if I do ps -all it will list me all the process that are running, but is there a way to know if mysql, apache or other process is running?

An example:
some_monitor_command mysql
some_monitor_command apache


Second question:
Sometimes I use more than one session at the same time, for example graphical mode, tty2 (using Alt+F2), tty3 (Alt+F3), so, I do everything I need in tty3 for example, my question is:

Once I finished to use tty3 is there a way to kill tty3? if I go to tty2 and I do a ps -all I can see the process in tty3, so I want to kill all the tt3, can you help me?

You can grep the results if you wish, such as "ps auxww | grep apache" and the like. This will return only the lines with 'apache' in them, and will scan all currently running processes.

Try using grep to find out what is running...for example:

Also if you don't know what you're looking for is called you can use different switches with grep (like grep -i) man grep for more details...

-C

Or -

ps -ef | grep httpd
ps -ef | grep mysql
