[root@mail src]# tar zxvf nagios-plugins-1.4.13.tar.gz

[root@mail src]# cd nagios-plugins-1.4.13
[root@mail nagios-plugins-1.4.13]# ./configure --prefix=/usr/local/nagios

[root@mail nagios-plugins-1.4.13]# make

[root@mail nagios-plugins-1.4.13]# make install

[root@mail nagios-plugins-1.4.13]# chown -R nagios.nagios /usr/local/nagios

[root@mail nagios-plugins-1.4.13]# cd ..

[root@mail src]# tar zxvf nrpe-2.8.1.tar.gz

[root@mail src]# cd nrpe-2.8.1

[root@mail nrpe-2.8.1]# ./configure --prefix=/usr/local/nrpe

[root@mail nrpe-2.8.1]# make all

[root@mail nrpe-2.8.1]# make install-plugin

[root@mail nrpe-2.8.1]# make install-daemon

[root@mail nrpe-2.8.1]# make install-daemon-config
