或者
cpan -i Nagios::Plugin
第一次安装如果中间有报:
Do you want to modify/update your configuration (y|n) ? [no] no
这里提示要不要对原有网络配置进行更新修改,我们选择no
Shall I follow them and prepend them to the queue of modules we are processing right now? [yes] yes
这里提示须跟随他们和他们预队列中我们现在正在处理的模块吗,直接输入yes.
好了,下面就是等待了,可能会有上面几次的重复提示,都安装上吧,安装完后,出现
cpan>
输入exit退出.

YAML是以数据为中央的标记语言，其使用ASCII码（如连字符、问号、冒号、逗号等）构造数据块（标量值或哈希码）。和XML相同，YAML也是一种机器可识别语言，并能和多种脚本语言相结合，其中一种便是Perl，需要安装YAML，如下执行：
cpan[2]>install YAML
