CentOS换内核（为了上锐速）.md

VPS到手之后，有些内核锐速是不支持的，所以需要换一下

CentOS 6

使用epel

yum install epel-release -y yum update -y yum install kernel-2.6.32-573.1.1.el6.x86_64 -y

使用91yun提供的内核

rpm -ivh http://soft.91yun.org/ISO/Linux/CentOS/kernel/kernel-firmware-2.6.32-504.3.3.el6.noarch.rpm --force rpm -ivh http://soft.91yun.org/ISO/Linux/CentOS/kernel/kernel-2.6.32-504.3.3.el6.x86_64.rpm --force

CentOS 7

rpm -ivh http://soft.91yun.org/ISO/Linux/CentOS/kernel/kernel-3.10.0-229.1.2.el7.x86_64.rpm --force

看是否成功

rpm -qa | grep kernel

重启再看一遍

reboot uname -r
