Automatic Startup

Control the running of your Nagios server using init scripts or daemontools.

Init Script
If you installed the included startup scripts, add them to the system services and have it automatically start at system boot:

chkconfig --add nagios
chkconfig nagios on

Verify your initial Nagios configuration:

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

And if there are no errors, you can control Nagios with:

/etc/rc.d/init.d/nagios {start|stop|restart|reload|force-reload|status}

or

service nagios {start|stop|restart|reload|force-reload|status}

Technology:

Convert-Multilog

A utility to make the logs generated by multilog and daemontools easier to read and archive.

Convert-Multilog
In order to get some nicer logs from our daemontool services, we'll use some of John Simpson's convert-multilog script to automatically clean them up and put daily log files into "/var/log".

Technology:

Daemontools

daemontools is a collection of tools for managing UNIX services that was created by Daniel J. Bernstein.

To simplify management of the various daemons on the server, install daemontools. Asides from some other benefits, a really nice thing about daemontools is that gives a consistent means of managing different services rather than a mish-mosh of different init scripts, rc.d scripts, etc.

Installation
Setup a directory to download your source file into:

mkdir -p /package
chmod 1755 /package
cd /package
