新机器上线流程#
做RAID 10 , 将所有硬盘整合为一个 /sda , 也就是安装系统的时候只看到一个硬盘
安装 CentOS 系统 , 选择英文 , 机器命名 为 e2 , e3 , e3 ... e5 ...
所有东西都默认
配置网卡#
进入目录 /etc/sysconfig/network-scripts
编辑或新建如下的3个文件
将其中的IP修改为机器的IP
ifcfg-eth0#
编辑如下
DEVICE="eth0"
HWADDR="00:25:90:66:3F:EE" #装完系统是什么就是什么, 不需要修改
NM_CONTROLLED="yes"
BOOTPROTO=none
ONBOOT="yes"
USERCTL=no
BRIDGE=xenbr0
ifcfg-eth1#
编辑如下
DEVICE="eth1"
HWADDR="00:25:90:66:3F:EF" #装完系统是什么就是什么, 不需要修改
NM_CONTROLLED="yes"
ONBOOT="yes"
BOOTPROTO=none
IPADDR="10.10.2.8"
NETMASK="255.255.255.0"
ifcfg-xenbr0#
编辑如下
DEVICE=xenbr0
TYPE=bridge
ONBOOT="yes"
BOOTPROTO=none
IPADDR="113.11.199.8"
GATEWAY="113.11.199.1"
NETMASK="255.255.255.0"

参考#
hardware prefetch is not recommanded by oracle； 有人说 c-state不稳定且降低性能；
With both sandy and the previous gen, turbo gets disabled if you disable EIST.
