cent os -- 关闭掉无用的kernel模块

最近优化magento花了很多时间,当然也花了很多时间有linux系统的管理配置方面,总知是订单式的学习.用到什么就学习什么,之后再系统的总结.最近困扰了很久,虽然说很简单.就是如何去掉无用的一些kernel模块,这样也可以节省一些内存,虽然对magento来讲这点内存不算什么,当然对安全性也有点好处.

 

google之后得到两种答案:

 

echo 'alias net-pf-31 off' >> /etc/modprobe.conf

实际上就是编辑/etc/modprobe.con文件,加上一行alias net-pf-31 off.

 

另外一个就是使用blacklist.就是在/etc/modprobe.d文件后面添加一行.

blacklist matroxfb_base(这个便是不想加载的kernel模块名吧)

不过从文件的说明中感觉不是用来做这个用的. --------------------
