* sudo useradd -m nagios * sudo passwd nagios * sudo groupadd nagcmd * sudo usermod -a -G nagcmd nagios * sudo usermod -a -G nagcmd www-data

Now install the Nagios tarballs that were downloaded previously:

tar -zxvf nagios-3.2.1.tar.gz

Then cd the the extracted folder and install

cd nagios-3.2.1 sudo ./configure --with-command-group=nagcmd sudo make all sudo make install sudo make install-init sudo make install-config sudo make install-commandmode sudo make install-webconf

Add a user for the Nagios interface:

sudo mkdir /usr/local/nagios/etc

Create a new password

sudo htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
