Nagios nrpe客户端的安装与配置
1.Nrpe安装创建 nagios用户useradd nagios1.1被监控服务器安装nagios插件tar xzvfnagios-plugins-1.4.15.tar.gzcd nagios-plugins-1.4.15./configuremakemake install
1.2被监控服务器安装nrpe程序tar xzvfnrpe-2.1.2.tar.gzcd nrpe-2.1.2./configure --prefix=/usr/local/nagiosmake allmake install-pluginmake install-daemonmake install-daemon-config检查插件安装ll /usr/local/nagios/libexec/
1.3修改nrpe配置文件，加入允许的IP#vi/usr/local/nagios/etc/nrpe.cfgallowed_hosts=127.0.0.1,192.169.0.201启动nrpe#/usr/local/nagios/bin/nrpe -c/usr/local/nagios/etc/nrpe.cfg –d# netstat -plnt |grep nrpetcp 0 0 0.0.0.0:5666 0.0.0.0:* LISTEN 16831/nrpe
1.4加入开机自启动echo'/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d'>>/etc/rc.local
1.5在主Nagios上验证客户端nrpe是否安装好#/usr/local/nagios/libexec/check_nrpe -H 192.168.1.100NRPE v2.12若出现版本号，代表nrpe客户端安装成功。
2主Nagios调用nrpe配置2.1编辑客户端上的nrpe配置文件#vi /usr/local/nagios/etc/nrpe.cfgcommand=/usr/local/nagios/libexec/check_users-w 5 -c 10command=/usr/local/nagios/libexec/check_load-w 15,10,5 -c 30,25,20
2.2在主Nagios上定义客户端主机#vi /usr/local/nagios/etc/objects/hosts.cfgdefine host{ use linux-server,host-pnp host_name hostb alias hostb address 192.168.1.100 }
2.3在主Nagios上配置服务#vi /usr/local/nagios/etc/objects/services.cfgdefine service{ use generic-service,srv-pnp host_name hostb service_description check_users check_command check_nrpe!check_users max_check_attempts 5 normal_check_interval 1}define service{ use generic-service,srv-pnp host_name hostb service_description check_load check_command check_nrpe!check_load max_check_attempts 5 normal_check_interval 1}
2.4重启主Nagios服务#/etc/init.d/nagios checkconfig#/etc/init.d/nagios restart
