Nagios安装说明

*****Nagios安装思路*****详情参照55DAY*****

一、Nagios服务端安装

1、安装所需依赖关系包

2、添加Nagios所需用户及组

3、编译安装Nagios及创建登陆Nagios WEB程序用户

4、Nagios-plugin(插件)

5、配置服务自启动

二、基于NRPE配置Nagios监控Win主机

1、被监控端

安装：NSClient++-0.3.9-x64

2、监控端

1.测试与被监控端连通性

2.监控端定义命令、定义主机、定义服务

3.将定义好的模板加入到nagios.cfg文件中

4.重启服务

三、基于NRPE监控Linux主机

1、被监控端：

1.添加用户

2.安装插件nagios-plugins-1.4.15

3.安装NRPE

4.配置NRPE配置文件

#vi /usr/local/nagios/etc/nrpe.cfg

5.定义nrpe启动脚本且增加权限

6.添加自启动

7.启动服务

2、配置监控端：

1.安装NRPE

安装完成后，生成check_nrpe，使用此插件进行测试被监控主机

2.定义命令

3.定义主机和服务

4.将定义好的linhost.cfg配置文件的路径添加至/usr/localhost/etc/nagios.cfg中

5.测试配置文件  /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

6.重启服务

7.网页检查hosts监控状况

******另关于基于NRPE监控windows主机,另行查询网上资料******

一、安装配置Nagios

1、解决安装Nagios的依赖关系：

# yum -y install httpd gcc glibc glibc-common gd gd-devel php php-mysql mysql mysql-devel mysql-server

2、添加nagios运行所需要的用户和组：

# groupadd  nagcmd

# useradd -G nagcmd nagios

# passwd nagios

# usermod -a -G nagcmd apache

3、编译安装nagios：

# tar zxf nagios-3.3.1.tar.gz

# cd nagios-3.3.1

# ./configure --with-command-group=nagcmd --enable-event-broker

# make all

# make install

# make install-init

# make install-commandmode

# make install-config

# vi /usr/local/nagios/etc/objects/contacts.cfg

[email protected]       #这个是默认设置

# make install-webconf

# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

# service httpd restart

4、编译、安装nagios-plugins

# tar zxf nagios-plugins-1.4.15.tar.gz

# cd nagios-plugins-1.4.15

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

# make

# make install

5、配置并启动Nagios

#vi /usr/local/nagios/etc/nagios.cfg

# chkconfig --add nagios

# chkconfig nagios on

# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

# service nagios start

6、配置selinux

#getenforce

#setenforce 0

7、通过web界面查看nagios：

http://your_nagios_IP/nagios

登录时需要指定前面设定的web认证帐号和密码。

二、配置文件

Nagios的主配置文件

/usr/local/nagios/etc/nagios.cfg

Nagios模板配置目录

/usr/local/nagios/etc/objects

调用check命令目录/usr/local/nagios/libexec

三、基于NSClinet++  监控远程Win主机

1、安装配置被监控端

安装NSClient++-0.3.9-x64

2、进行测试是否连通

#cd /usr/local/nagios/libexec

#./check_nt -H 192.168.1.119 -v UPTIME -p 12489

如有密码则：#./check_nt -H 192.168.1.119 -v UPTIME -p 12489 -s luoxj,123

3、监控端进行配置

&&&定义commands.cfg-------------------定义命令

#cd /usr/local/nagios/etc/objects/

#vi commands.cfg

define command{

command_name    check_nt

command_line    $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -v $ARG1$ $ARG2$

}

&&&定义主机及服务

#vi windows.cfg

define host{

use             windows-server

host_name       winhost

alias           My Windows Host

address         192.168.1.119

}

define service{        use                     generic-service        host_name               winhost        service_description     NSClient++ Version        check_command           check_nt!CLIENTVERSION        }定义服务可根据实际情况进行变更名称可使用vim中替换进行：.,[email protected]@[email protected]

&&&启用定义的文件，增加定义文件路径

#vi /usr/local/nagios/etc/nagios.cfg

cfg_file=/usr/local/nagios/etc/objects/windows.cfg

&&&进行测试，以确定配置文件没有问题

# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg -d

#service nagios restart

四、基于NRPE监控远程Linux主机

1、安装配置被监控端

1）先添加nagios用户

# useradd -s /sbin/nologin nagios

2）NRPE依赖于nagios-plugins，因此，需要先安装之

# tar zxf nagios-plugins-1.4.15.tar.gz

# cd nagios-plugins-1.4.15

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

# make all

# make instal

3）安装NRPE

# tar -zxvf nrpe-2.12.tar.gz

# cd nrpe-2.12.tar.gz

# ./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

4）配置NRPE

# vim /usr/local/nagios/etc/nrpe.conf

log_facility=daemon

pid_file=/var/run/nrpe.pid

server_address=172.16.100.11

server_port=5666

nrpe_user=nagios

nrpe_group=nagios

allowed_hosts=172.16.100.1

command_timeout=60

connection_timeout=300

debug=0

&&&&&&&&定义监控对象命令&&&&&&&&&

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

command[check_sda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/sda1

command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z

command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200

5）启动NRPE

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

为了便于NRPE服务的启动，可以将如下内容定义为/etc/init.d/nrped脚本：

#vi /etc/init.d/nrped

#!/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

#chmod +x /etc/init.d/nrped

#service nrped start

#netstat -tnlp    ##检查nrpe端口5666是否启用

tcp        0      0 0.0.0.0:5666                0.0.0.0:*                   LISTEN      17282/nrpe

#service iptables stop

#setenforce 0

6）配置允许远程主机监控的对象

在被监控端，可以通过NRPE监控的服务或资源需要通过nrpe.conf文件使用命令进行定义，定义命令的语法格式为：command[<command_name>]=<command_to_execute>。比如：

command[check_rootdisk]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /

command[check_swap]=/usr/local/nagios/libexec/check_disk -w 40% -c 20%

command[check_sensors]=/usr/local/nagios/libexec/check_sensors

command[check_users]=/usr/local/nagios/libexec/check_users -w 10 -c 20

command[check_load]=/usr/local/nagios/libexec/check_load -w 10,8,5 -c 20,18,15

command[check_zombies]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z

command[check_all_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200

2、配置监控端

1）安装NRPE

# tar -zxvf nrpe-2.12.tar.gz

# cd nrpe-2.12.tar.gz

# ./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

安装完成后，/usr/local/nagios/libexec/check_nrpe就会生成此插件，可测试客户端工作正常于否

#cd /usr/local/nagios/libexec/

#./check_nrpe -H 192.168.1.124

NRPE v2.12

2）定义如何监控远程主机及服务：

通过NRPE监控远程Linux主机要使用chech_nrpe插件进行，其语法格式如下：

check_nrpe -H <host> [-n] [-u] [-p <port>] [-t <timeout>] [-c <command>] [-a <arglist...>]

定义监控远程Linux主机的命令：

#vi /usr/local/nagios/etc/objects/commands.cfg   添加nrpe命令

define command{

command_name    check_nrpe

command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$

}

************建立模板文件******************

#cd /usr/local/nagios/etc/objects/

#vim linhost.cfg   或是  #cp localhost.cfg linhost.cfg

***定义远程Linux主机：

define host{

use                     linux-server

host_name         linhost

alias                   my Linux Host

address              192.168.1.124

}

如主机组不需要则注释，添加服务可参照被监控端/usr/local/nagios/etc/nrpe.cfg中的command[check_users]=/usr/local/nagios/libexec/check_users -w 5 -c 10command[check_load]=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20command[check_sda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/sda1command[check_zombie_procs]=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Zcommand[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200 进行详细配置服务 ***定义远程Linux服务：也可以在后加参数进行设定监控
 define service{
        use                     generic-service        host_name               linhost        service_description     check_users        check_command           check_nrpe!check_users        }# Create a service for monitoring the uptime of the server
# Change the host_name to match the name of the host you defined abovedefine service{        use                     generic-service        host_name               linhost        service_description     load        check_command           check_nrpe!check_load        }# Create a service for monitoring CPU load
# Change the host_name to match the name of the host you defined abovedefine service{        use                     generic-service        host_name               linhost        service_description     sda1        check_command           check_nrpe!check_sda1        }# Create a service for monitoring memory usage
# Change the host_name to match the name of the host you defined abovedefine service{        use                     generic-service        host_name               linhost        service_description     Zombie        check_command           check_nrpe!check_zombie_procs        }define service{        use                     generic-service        host_name               linhost        service_description     Total procs        check_command           check_nrpe!check_total_procs        }3）将设定好的linhost.cfg文件添加至/usr/local/nagios/etc/nagios.cfg中#vi /usr/local/nagios/etc/nagios.cfg

cfg_file=/usr/local/nagios/etc/objects/linhost.cfg

4）进行测试配置文件 # /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg5）重启服务#service nagios restart
