Nagiosnrpe客户端的安装与配置-创新互联

1.Nrpe安装

创建 nagios用户

useradd nagios

1.1被监控服务器安装nagios插件

tar xzvfnagios-plugins-1.4.15.tar.gz

cd nagios-plugins-1.4.15

./configure

make

make install

1.2被监控服务器安装nrpe程序

tar xzvf  nrpe-2.1.2.tar.gz

cd nrpe-2.1.2

./configure --prefix=/usr/local/nagios

make all

make install-plugin

make install-daemon

make 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.cfg

allowed_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 nrpe

tcp     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

[root@nagios-server src]#/usr/local/nagios/libexec/check_nrpe -H 192.168.1.100

NRPE 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.cfg

command[check_users]=/usr/local/nagios/libexec/check_users-w 5 -c 10

command[check_load]=/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.cfg

define 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.cfg

define 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
