you seem not to be familiar with linux in any way... otherways you would
know that ps tells you abot the process status. With "man ps" on the
console (without the ") you get more info.

Or you may even try to enter ps --help, just as you are told... ;-)

Well, since you did not configure nagios (this is what nagios tells you
here), nagios cannot start. So when you invoke the nagios start script
nagios does not start and the pid file does not exist. This start script
uses "ps -p $NagiosPID" to determine whether nagios runs or not. Since
there is not $NagiosPID (nagios did not start because of the missing
config) you get the error message you gave at the beginning.

So, first configure nagios, then call "/usr/local/nagios/bin/nagios -v
> /usr/local/nagios/etc/nagios.cfg" to see if the config is correct and
only then you may "/etc/init.d/nagios start".

BTW: did you "make install-config" after "make install"?
