CentOS 配置
修改 /etc/sysconfig/network-scripts/ifcfg-eth0 配置文件，将 ONBOOT=no 改为 ONBOOT=yes，并重启 network 服务：
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=此处为马赛克
TYPE=Ethernet
UUID=9e8e00ed-1dfd-4eb7-bd83-468500b29f4e
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=dhcp
[root@localhost ~]# service network restart
正在关闭接口 eth0： [确定]
关闭环回接口： [确定]
弹出环回接口： [确定]
弹出界面 eth0：
正在决定 eth0 的 IP 信息...完成。
[确定]
如需配置静态 IP 地址，修改 /etc/sysconfig/network-scripts/ifcfg-eth0 配置文件，将 BOOTPROTO=dhcp 改为 BOOTPROTO=static，添加静态 IP 信息（IPADDR、NETMASK、GATEWAY），并重启 network 服务：
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=此处为马赛克
TYPE=Ethernet
UUID=9e8e00ed-1dfd-4eb7-bd83-468500b29f4e
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=static
IPADDR=192.168.1.233
NETMASK=255.255.255.0
GATEWAY=192.168.1.1
DNS1=192.168.1.1
测试网络
使用 ifconfig -a 命令查询 CentOS 的 IP 地址，使用 ping 命令测试是否可以访问互联网：
[root@localhost ~]# ifconfig -a

附录
CentOS 常用系统目录结构
-
/binbin 是 Binary 的缩写, 这个目录存放着最经常使用的命令。 -
/etc这个目录用来存放所有的系统管理所需要的配置文件和子目录。 -
/home用户的主目录，在 Linux 中，每个用户都有一个自己的目录，一般该目录名是以用户的账号命名的。 -
/opt这是给主机额外安装软件所摆放的目录。比如你安装一个 ORACLE 数据库则就可以放到这个目录下。默认是空的。 -
/root该目录为系统管理员，也称作超级权限者的用户主目录。 -
/sbins 就是 Super User 的意思，这里存放的是系统管理员使用的系统管理程序。 -
/tmp这个目录是用来存放一些临时文件的。 -
/usr这是一个非常重要的目录，用户的很多应用程序和文件都放在这个目录下，类似于 windows 下的 program files 目录。 -
/var这个目录中存放着在不断扩充着的东西，我们习惯将那些经常被修改的目录放在这个目录下。包括各种日志文件。
