修改主机名：
复制代码代码如下:
#vi /etc/sysconfig/network
NETWORKING=yes
#HOSTNAME=localhost.localdomain
HOSTNAME=CentOS-1
#也可以在这里设置网关
#GATEWAY=192。168.30.1
设置网络为DHCP获取
复制代码代码如下:
vi /etc/sysconfig/network-scrip/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO="dhcp"
HWADDR="08:00:27:A7:AB:97"
NM_CONTROLLED="no"
ONBOOT="no"
TYPE="Ethernet"
UUID="9622f9e1-6218-4c56-9f45-7ae29b477e89"
设置静态IP
复制代码代码如下:
vi /etc/sysconfig/network-scrip/ifcfg-eth0
[root@CentOS-3 ssh]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
HWADDR=08:00:27:e2:62:9b

USERCTL=no
IPV6INIT=no
