II- Install and Configure Nagios :

  • Then cd the the extracted folder and install

cd nagios-3.3.1
sudo ./configure -with-command-group=nagcmd
sudo make all
sudo make install

if you get this error

make[1]: *** [install] Error 1
make[1]: Leaving directory `/media/europa/callisto/nagios___/nagios-3.3.1/nagios/html'
make: *** [install] Error 2

 

Please solve the issue Like this :

 

./configure

sed -i 's:for file in includes/rss/*;:for file in includes/rss/*.*;:g' ./html/Makefile
sed -i 's:for file in includes/rss/extlib/*;:for file in includes/rss/extlib/*.*;:g' ./html/Makefile

and then
make fullinstall

 
 

  • This installs the init script in /etc/rc.d
 sudo make install-init
  • This installs sample config files in /usr/local/nagios/etc
 sudo make install-config
  •  This installs and configures permissions on the directory for holding the external command file
sudo make install-commandmode

ann  nagios  config to apache
