服务器最小化安装后的优化脚本，此脚本在CentOS\[5.5-5.8\] x86\_64系统下测试均顺利通过， 由于现在Linux服务器系统都是采用Kickstart批量安装的方式，此脚本可以由Puppet服务器推送执行，脚本内容如下所示：

脚本重点部分说明：

tune kernel parametres为系统内核优化部分，在这里我只做了基础处理，大家有需求可以自行修改，记住：一切以系统稳定为原则。

vim优化部分为vim的个性化配置，如果想vim语法高亮，则必须安装vim-enhanced包，另外，vim在使用搜索功能，搜索选中内容为高亮，感觉不是特别舒服，所以我这里用了set nohlsearch选项，如果大家不介意此项功能，则不需要添加此语句；

disable ipv6选项我在测试时发现，在CentOS5.8 x86\_64系统下，如果不添加install ipv6 /bin/true此语句到/etc/modprobe.conf文件里，是关闭不了ipv6选项的，而测试的CentOS\{5.5,5,6\} x86\_64系统不添加此句均可以顺利关闭ipv6，这点请大家注意下。
