安装nagios+监控Linux客户端服务端+监控windows客户端

 1.解决依赖包 yum -y install httpd gcc glibc glibc-common gd gd-devel php php-mysql 

 mysql mysql-devel mysql-server

 

2添加nagios运行所需的用户和组

 

groupadd nagcmd 

useradd -G nagcmd nagios

passwd nagios

把apache加入到nagcmd组

usermod -a -G nagcmd apache

 

3编译nagios

 

tar zxvf nagios-3.4.1.tar.gz

cd nagios-3.4.1

./configure --sysconfdir=/etc/nagios --with-command-group=nagcmd --enable-event-broker

 

make all

make install

make install-init

make install-commandmode

make install-config

make install-webconf

 

创建一个登录nagios web程序的用户

htpasswd -c /etc/nagios/htpasswd.users nagiosadmin

 

service httpd start (如果遇到Starting httpd: httpd: Could not reliably determine the server's fully quali)

vi /etc/httpd/conf/httpd.conf 把ServerName www.example.com:80的注释去掉

 

4安装nagios-plugins

 

tar zxvf nagios-plugins

cd nagios-plugins

./configure --with-nagios-user=nagios --with-nagios-group=nagios

make

make install

 

service nagios start

 

setenforce 0

nagios监控Linux服务端的配置

 

tar zvxf nrpe-2.13

cd nrpe-2.13

./configure --with-nrpe-user=nagios \

   --with-nrpe-group=nagios \

   --with-nagios-user=nagios \

   --with-nagios-group=nagios \

   --enable-command-args \

   --enable-ssl

make all 

make install-plugin

----------------------------------------------------------------------------------------------------------

nagios监控Linux客户端的配置

 

 

基于nrpe监控Linux

1.nrpe 依赖与nagios-plugins (5666端口) 

在被监控端安装nagios-plugins 

先检查看有没有安装开发包组   yum grouplist

 

yum -y groupinstall "Development Tools" "Development Libraries"

 

添加用户

useradd -s /sbin/nologin nagios

tar xf nagios-plugins

cd nagios-plugins

./configure --with-nagios-user=nagios --with-nagios-group=nagios

make all

make install

 

2.安装nrpe 

 

tar zvxf nrpe-2.13

cd nrpe-2.13

./configure --with-nrpe-user=nagios \

   --with-nrpe-group=nagios \

   --with-nagios-user=nagios \

   --with-nagios-group=nagios \

   --enable-command-args \

   --enable-ssl

make all 

make install-plugin

make install-daemon

make install-daemon-config

 

3配置nrpe

 

vim /usr/local/nagios/etc/nrpe.cfg

 

修改 allowed_hosts=192.168.142.11

 

4启动nrpe

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

或者通过脚本

vim /etc/init.d/nrpe

 

#!/bin/bash

# chkconfig: 2345 88 12

# description: NRPE DAEMON

NRPE=/usr/local/nagios/bin/nrpe

NRPECONF=/usr/local/nagios/etc/nrpe.cfg

 

case "$1" in

        start)

 

                echo -n "Starting NRPE daemon..."

               $NRPE -c $NRPECONF -d

               echo "done."

               ;;

        stop)

 

               echo -n "Stopping NRPE daemon..."

               pkill -u nagios nrpe

               echo " done."

        ;;

        restart)

               $0 stop

               sleep 2

               $0 start

               ;;

        *)

               echo "Usage: $0 start|stop|restart"

               ;;

          esac

    exit 0

nagios监控windows客户端的配置

 

 

1.windows客户端安装一个nscclient++ （需要定义主机，服务，联系人）

  在windows 客户端 用netstat -an 查看是否有12489的端口

 

2.回到监控端 cd /usr/local/nagios/libexec (全是命令)

   ./check_nt -h 查看用法

   如 ./check_nt -H 192.168.142.50 -p 12489(端口) -v UPTIME (命令)

      ./check_nt -H 192.168.142.50 -p 12489 -v CPULOAD -w 80 -c 90 -l 5,80,90

      ./check_nt -H 192.168.142.50 -p 12489 -v USEDDISKSPACE -w 80 -c 80 -l 5,80,90

   

3.cd /etc/nagios/object

 vim commands.cfg  

 定义一个命令

 

define command {

        command_name check_nt

        command_line $USER1$/check_nt -H $HOSTADDRESS$ -v $ARG1$ $ARG2$

}

 

4 vim windows.cfg

 

把主机名字改为winhost

 

把地址改为要监控的地址如192.168.142.50

 

改所有 :.,$s@winserver@winhost@g

 

保存退出

 

5启用文件 windows.cfg

 

cd /etc/nagios

 

vim nagios.cfg

 

把cfg_file处加个 cfg_file=/etc/nagios/objects/windows.cfg

 

保存退出

 

6查错 /usr/local/nagios/bin/nagios -v /etc/nagios/nagios.cfg

 

然后重启  service nagios restart
