Installing Nagios on Ubuntu 12.04

less than 1 minute read

This is just a quick Nagios setup guide for installing on Ubuntu. This will get you up and running quickly. May create a github script at some point to auto install.

sudo apt-get install wget build-essential apache2 php5-gd libgd2-xpm libgd2-xpm-dev libapache2-mod-php5 libssl-dev sendmail mrtg

cd /tmp

useradd nagios
groupadd nagcmd
usermod -a -G nagcmd nagios

cd nagios
./configure --with-nagios-group=nagios --with-command-group=nagcmd
./configure --with-mail=/usr/bin/sendmail

make all
make install
make install-init
make install-config
make install-commandmode
make install-webconf

cp -R contrib/eventhandlers/ /usr/local/nagios/libexec/
chown -R nagios:nagios /usr/local/nagios/libexec/eventhandlers
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

/etc/init.d/nagios start
htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
cd /tmp/nagios-plugins-1.4.15
./configure --with-nagios-user=nagios --with-nagios-group=nagios
make install

ln -s /etc/init.d/nagios /etc/rcS.d/S99nagios

Now open your browser and login to your new Nagios Web UI.
