安装好RHEL 5.5基础版后，我事先将光盘作为yum源，具体看本人之前随笔。相关rpm可在http://pkgs.repoforge.org/查找，个别缺失用google吧。

监控主机HostA：

#yum install httpd php gd
#rpm -ivh nagios-3.2.3-3.el5.rf.i386.rpm nagios-plugins-1.4.9-1.el5.rf.i386.rpm nagios-plugins-nrpe-2.5.2-1.el5.rf.i386.rpm nagios-plugins-setuid-1.4.9-1.el5.rf.i386.rpm nginx-1.2.0-1.el5.ngx.i386.rpm perl-Crypt-DES-2.05-3.2.el5.rf.i386.rpm perl-Digest-HMAC-1.02-1.el5.rf.noarch.rpm perl-Digest-SHA1-2.13-1.el5.rfx.i386.rpm perl-Net-SNMP-5.2.0-1.2.el5.rf.noarch.rpm perl-Socket6-0.23-1.el5.rfx.i386.rpm
#htpasswd -bc /etc/nagios/htpasswd.users nagiosadmin password
#setenforce 0 或者修改/etc/selinux/config使之永久有效
#chkconfig --level 345 httpd on
#chkconfig --level 345 nagios on
#reboot
#http://HostA/nagios

被控Windows主机HostB：

http://nsclient.org/nscp/downloads 下载最新NSClient++，并安装
注意安装目录下NSC.ini中的
- [Settings]
  - allowed_hosts=
  - password=
- [NRPE]
  - port=5666
#vi /etc/nagios/nagios.cfg
- cfg_file=/usr/local/nagios/etc/objects/windows.cfg
windows.cfg
- 修改主机对象 host_name,alias,address
验证，重启nagios

被控Linux主机HostC：

# rpm -ivh nagios-nrpe-2.5.2-1.el5.rf.i386.rpm nagios-plugins-1.4.9-1.el5.rf.i386.rpm perl-Crypt-DES-2.05-3.2.el5.rf.i386.rpm perl-Digest-HMAC-1.02-1.el5.rf.noarch.rpm perl-Digest-SHA1-2.13-1.el5.rfx.i386.rpm perl-Net-SNMP-5.2.0-1.2.el5.rf.noarch.rpm perl-Socket6-0.23-1.el5.rfx.i386.rpm fping-2.4-1.b2.3.el5.rf.i386.rpm
vi /etc/nagios/nrpe.cfg
- allowed_hosts=127.0.0.1,HostA_ip
nrpe -c /etc/nagios/nrpe.cfg -d #运行nrpe
vi /etc/sysconfig/iptables
- -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5666 -j ACCEPT
netstat -an|grep 5666

在HostA上执行

#/usr/lib/nagios/plugins/check_nrpe -H 192.168.128.59
返回NRPE v2.5.1，OK
cp /etc/nagios/objects/localhost.cfg /etc/nagios/objects/linuxs.cfg

vi /etc/nagios/objects/linuxs.cfg

# Definitions for monitoring the Linux hosts
cfg_file=/etc/nagios/objects/linuxs.cfg
