win7下安装Centos
同一块硬盘时：win启动项没有，使用pe进行修复，之后用easybcd进行centos启动项修复，grub2，自动搜索
两块硬盘时：不要动启动项，bios选启动的硬盘即可
linux下挂在window硬盘
yum install ntfs-3g
vi /etc/fstab
/dev/sda1 /mnt/winC ntfs-3g defaults 0 0
/dev/sda2 /mnt/winD ntfs-3g defaults 0 0

The file /usr/src/kernels/3.10.0-514.2.2.el7.x86_64/include/linux/version.h does not exist.
用命令 sudo ln -s <内核头文件目录>/generated/uapi/linux/version.h <内核头文件目录>/include/linux/version.h
sudo ln -s /usr/src/kernels/3.10.0-229.el7.x86_64/include/generated/uapi/linux/version.h /usr/src/kernels/3.10.0-229.el7.x86_64/include/linux/version.h

修改yum源
1、备份
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup
2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/
CentOS 5
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo
CentOS 6
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo
CentOS 7
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
3、之后运行yum makecache生成缓存
配置DNS
vi /etc/resolv.conf
加入

加入：
GATEWAY=192.168.0.1
配置ip地址：
vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
HWADDR="00:0C:29:6C:BB:E6"
NM_CONTROLLED="yes"
ONBOOT="no"
NETMASK=255.255.255.0
IPADDR=192.168.0.8
GATEWAY=192.168.0.1
BOOTPROTO=static
ONBOOT=yes
PEERDNS=yes
重启服务
