Nagios

After 2+ years of uptime, my Nagios box went down unexpectedly and I decided to take the opportunity to create a new box using Fedora Core 9 with a fairly minimal install.

I used the following instructions from start to finish with minor alterations and had good success:

For my reference, here are the steps I used (minus passwords)

yum install httpd
yum install gcc
yum install glibc glibc-common
yum install gd gd-devel 
/usr/sbin/useradd -m nagios
passwd nagios 
/usr/sbin/groupadd nagcmd
/usr/sbin/usermod -G nagcmd nagios
/usr/sbin/usermod -G nagcmd apache 
mkdir ~/downloads
cd ~/downloads 
wget http://osdn.dl.sourceforge.net/sourceforge/nagios/nagios-3.0.3.tar.gz
wget http://osdn.dl.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.12.tar.gz 
cd ~/downloads
tar xzf nagios-3.0.3.tar.gz
cd nagios-3.0.3 
./configure --with-command-group=nagcmd 
make all 
make install
make install-init
make install-config
make install-commandmode 
make install-webconf 
htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin 
service httpd restart 
cd ~/downloads
tar xzf nagios-plugins-1.4.12.tar.gz
cd nagios-plugins-1.4.12
./configure --with-nagios-user=nagios --with-nagios-group=nagios
make
make install 
chkconfig --add nagios
chkconfig nagios on 
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 
# import backed up cfg files to /usr/local/nagios/etc
service nagios start
# check http://localhost/nagios
