NDO2DB startup script for RH (EL) / OEL

Below a script designed to use the RH . /etc/init.d/functions library. It will use 2 “find” commands to test if it can find the ndo2db binairy and config file. Next it will daemonize the ndo2db process following the Redhat standard init procedure.

This script was written for Redhat enterprise linux using Nagios, Centreon (auto generation of the config)

Edit the “searchdir” for a broader searchscope. In the current code the nagios tree is searched for both the config and the ndo2db binairy.

touch a file in the init.d like so.

touch /etc/init.d/ndodaemon

NExt edit the file and add the code below.

vi /etc/init.d/ndodaemon

Please note the fact that this script uses the /etc/init.d/functions file. Not all linux distro`s deliver this file. Do check its availability in your own distro!

                        status $NDODAEMON

                *)

                echo $"Usage: $prog {start|stop|restart|condrestart|reload|status}"
                exit 3
        esac
exit $RETVAL

Next if you have chkconfig available as package, you should be able to add the script to the linux init using the commands;

chkconfig --add ndodaemon
chkconfig --level 2345 ndodaemon on

start the ndodaemon manually using

/etc/init.d/ndodaemon start
#or
service ndodaemon start

For those not using Centreon (a shame ) here is an example (default) ndo2db configuration file.
