[root@nagios nagios-4.2.4]# make all && make install && make install-init && make install-commandmode && make install-config
[root@nagios nagios-4.2.4]# cp -R contrib/eventhandlers/ /usr/local/nagios/libexec/
[root@nagios nagios-4.2.4]# chown -R nagios:nagios /usr/local/nagios/libexec/eventhandlers
[root@nagios nagios-4.2.4]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
