[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
