1、安装并配置Nagios插件

需要在Nagios服务器上安装并配置相应的插件,常用的插件有:

check_nrpe:用于远程主机的监控

check_ssh:用于SSH服务的监控

check_tcp:用于TCP服务的监控

check_disk:用于磁盘空间的监控

check_load:用于系统负载的监控

安装插件的方法如下:

“`bash

# 对于Ubuntu/Debian系统

sudo aptget install nagiosplugins

# 对于CentOS/RHEL系统

sudo yum install nagiosplugins

“`

2、配置自动发现插件

在Nagios服务器上,需要配置一个或多个自动发现插件,常用的自动发现插件有:

nsclient:用于远程主机的自动发现

nrpe:用于NRPE服务的自动发现

apache_status:用于Apache服务的自动发现

nginx_status:用于Nginx服务的自动发现

以nsclient为例,配置自动发现插件的方法如下:

1. 下载并安装nsclient:

“`bash

# 下载nsclient

wget https://files.pythonhosted.org/packages/f3/4a/0d6c9e7f859b64c0e9a7f253858345b6b1a02e2e4c9a0a0b9b3c67d7e4a/nsclient0.3.1.tar.gz

tar xvf nsclient0.3.1.tar.gz

cd nsclient0.3.1

# 安装nsclient

sudo python setup.py install

“`

2. 编辑Nagios配置文件(/etc/nagios3/nagios.cfg),在cfg_dir部分添加以下内容:

“`ini

cfg_dir=/usr/local/nagios/etc/objects

“`

3. 在cfg_dir目录下创建一个名为check_nsclient.cfg的文件,内容如下:

“`ini

define host {

use generichost

host_name myserver1

address 192.168.1.100

alias My Server 1
