1.此脚本在多台机器上测试成功。
2.nagios版本是nagios-3.2.1版本跑在httpd上
3.访问时：
输入: ip/nagios
4.页面用httpd的密码工具生成用户密码，用户是nagiosadmin(脚本里设置的，可自己改)。
5.弹出自己输入密码
6.脚本可能还有瑕疵,不知道依赖包考虑的是不是 完全.
7. naios.zip文件10M ，传不上来。上传到百度云里。有兴趣的可以下载，并在自己虚拟机上运行一次看下效果
下载地址：http://pan.baidu.com/s/1slJ5GIT 密码nexl8.脚本运行使用
当需要远程监控一台机器时,先在被监控端运行2,然后再监控端运行3.
这是运行1大概 的过程------------
##############----一键安装菜单----##############
# 1. 安装nagios 监控端
# 2. 安装远程被监控端
#3.监控端修改被监控端文件
#4. 退出
请输入菜单【1-4】1
正在检测yum源yum源检测通过!
