env: Ubunbu 12.04 + Nagios 3.X
Run by root
- Check_mk Server installation:
cd /root
/etc/init.d/nagios3 stop
dpkg-statoverride --update --add nagios www-data 2710 /var/lib/nagios3/rw
dpkg-statoverride --update --add nagios nagios 751 /var/lib/nagios3
/etc/init.d/nagios3 start
# Maybe not require to add user www-data in group nagios
# add www-data to group nagios (/etc/group)
# id -a www-data
apt-get install make build-essential xinetd
(package ucspi-unix is not required)
wget http://mathias-kettner.com/download/check_mk-1.2.4p5.tar.gz
tar xvf check_mk-1.2.4p5.tar.gz
cd check_mk-1.2.4p5
./setup.sh --yes
edit /etc/nagios3/nagios.cfg and change line broker_module to
broker_module=/usr/lib/check_mk/livestatus.o /var/lib/nagios3/rw/live
(with original package setup, it creates nagios.cfg with wrong one: /var/log/nagios/rw/live)
server xinetd restart
service nagios3 restart
service apache2 restart
You should see the check_mk website at http://HOSTNAME/check_mk/ and similar contents can be found in http://HOSTNAME/nagios3/, and you should see a socket file created:
srw-rw---- 1 nagios www-data 0 Nov 12 01:10 /var/lib/nagios3/rw/live
