First, FAN is a centos-based mini version of the system, you can directly download the iso image installation. It can also be installed on the redhat platform, which is generally installed on 32-bit systems on the redhat 5.x platform.

Official website: http://www.fullyautomatednagios.org/download/

Second, configure the network and dns

1.network

[root@oracle64 Desktop] # cat / etc/sysconfig/network-scripts/ifcfg-eth4

2.dns

[root@oracle64 Desktop] # cat / etc/resolv.conf

Search localdomain

Nameserver 210.21.4.130

Nameserver 221.5.88.88

Second, it is easy to install on a 32-bit system

1. Install epel-release

[root@oracle64 Desktop] # rpm-Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

two。 Install Graphviz repo:

4. 64-bit systems cannot be installed in this way. You need a fan_nagios_x86_64.repo.tar.gz package (this is a new source created by myself). You can extract the package directly to the / etc/yum.repos.d/ folder.
