运维自动化发展已经是势不可挡,传统的靠大量人力运维的方式渐不能满足企业IT发展的需求,其中Puppet自动化更是受到IT人士的青睐,那今天我们一起来研究一下puppet客户端的自动安装脚本。脚本不足之处,欢迎指正,共同进步!
背景:当我们需要使用puppet批量管理服务器时,首先需要指定FQDN名或者DNS解析,然后接下来就是批量安装puppet客户端了,怎样安装比较快呢?这里仅供参考,把脚本放置在kickstart ks.cfg文件%post段,系统安装完毕后,会执行该脚本!直接看脚本如下:
- #!/bin/sh
- #auto install puppet client
- #wugk 2012-11-30
- #PUPPET_SERVER=192-9-117-160-app.com
- #此脚本为客户端安装,同时包含服务器端安装,根据实际需求修改即可。
- cat <<EOF
- ++++++++++++++++++++welcome to use auto install puppet ++++++++++++++++++
