<strong>zypper install rrdtool php5 php5-gd php5-zlib apache2-mod_php5 perl-SNMP net-snmp-32bit nmap ncpfs libwavpack1 apache2</strong><br />
  • Now add   nagios user  to the system
 sudo useradd -m nagios
  • Create  a  nagios  home  directory ( is  requiered  to  start nagios)
mkdir  -p  /home/nagios
  • Create  password  for  nagios user

  • Add users nagios to group nagcmd  and  nagios  group

II- Install and Configure Nagios :



    

  • Now install the Nagios tarballs that we downloaded previously:
    • 



 tar -xvf nagios-3.3.1.tar.gz


    

  • 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


/usr/bin/install: omitting directory `includes/rss/extlib’
/usr/bin/install: omitting directory `includes/rss/htdocs’
/usr/bin/install: omitting directory `includes/rss/scripts’
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


sudo   make install-webconf


    

  • Make  a webadmin password for  nagios  admin
