<li>nagios 需要安装主程序和 nrpe（nagios 和各被监控主机都必须安装）。如需使用自研前端可通过安装 ndoutils (用于把 nagios 监控信息写入数据库) 和 mysql 实现。具体安装见<span class="exturl" data-url="aHR0cHM6Ly9zdXBwb3J0Lm5hZ2lvcy5jb20va2Iv">官网</span></li>
|
||||||
|
<li>nagios 默认监控命令脚本放置在 libexec 中，自定义脚本后也放到此处</li>
|
||||||
|
<li>etc/objects/commands.cfg 用于保存 nagios 默认监控命令</li>
|
||||||
|
<li>etc/nrpe.cfg 文件中需要添加用于被监控执行命令项（各被监控主机中都需要添加）<br />

<li>被监控端需要安装 nrpe</li>

<li>被监控端需要把命令执行脚本放入 libexec 目录中</li>
|

|
<li>被监控端自动安装脚本（可借鉴）</li>
|

</ol>
|
||||||
|
<pre><code class="language-bash">1、请先修改脚本中的服务端IP。
|
||||||
|
2、如被监控端不支持let计算命令请执行sudo dpkg-reconfigure dash命令，弹出选择窗口后选择no。
|
||||||
|
3、需要在脚本同目录下创建CentOS、Ubuntu、sh和conf目录，目录下分别放置nrpe的tar安装包、监控脚本和nrpe配置文件。

|

|
<ol>
|
||||||
|
<li>nagios 需要安装主程序和 nrpe（nagios 和各被监控主机都必须安装）。如需使用自研前端可通过安装 ndoutils (用于把 nagios 监控信息写入数据库) 和 mysql 实现。具体安装见<span class="exturl" data-url="aHR0cHM6Ly9zdXBwb3J0Lm5hZ2lvcy5jb20va2Iv">官网</span></li>
|
||||||
|
<li>nagios 默认监控命令脚本放置在 libexec 中，自定义脚本后也放到此处</li>
|
||||||
|
<li>etc/objects/commands.cfg 用于保存 nagios 默认监控命令</li>
|
||||||
|
<li>etc/nrpe.cfg 文件中需要添加用于被监控执行命令项（各被监控主机中都需要添加）<br />
|
||||||
|
<img data-src="https://file.jingxiyuan.cn/images/2022/10/18/image.png" alt="" /></li>
|
||||||
|
<li>etc/objects/hosts 目录下配置需要被监控的主机信息<br />
|
||||||
|
<img data-src="https://file.jingxiyuan.cn/images/2022/10/18/image2.png" alt="" /></li>
|
||||||
|
<li>etc/objects/servers 目录下配置需要在被监控主机上执行的监控命令（第 4 项中的命令）<br />

|

<ol>
|

|
<li>被监控端需要安装 nrpe</li>
|
||||||
|
<li>被监控端需要把监控端的命令写入到 nrpe 的配置文件中</li>
|
||||||
|
<li>被监控端需要把命令执行脚本放入 libexec 目录中</li>
|
||||||
|
<li>被监控端自动安装脚本（可借鉴）</li>
|
||||||
|
</ol>
|
||||||
|
<pre><code class="language-bash">1、请先修改脚本中的服务端IP。
|
||||||
|
2、如被监控端不支持let计算命令请执行sudo dpkg-reconfigure dash命令，弹出选择窗口后选择no。
|
||||||
|
3、需要在脚本同目录下创建CentOS、Ubuntu、sh和conf目录，目录下分别放置nrpe的tar安装包、监控脚本和nrpe配置文件。
