修改机器名和Ip

用vi编辑 /etc/sysconfig/network and /etc/sysconfig/network-scripts/ifcfg-eth0

1) /etc/sysconfig/network

NETWORKING = yes

FORWARD_IPV4 = yes

HOSTNAME = xxxx.com #你的主机名

GATEWAY = 123.123.123.123 #网关

GATEWAYDEV = eth0

2) /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE = eth0

IPADDR = xxx.xxx.xxx.xxx #你的IP地址

NETMASK = xxx.xxx.xxx.xxx #你的子网掩码

NETWORK = xxx.xxx.xxx.xxx #你的工作网络

BROADCAST = xxx.xxx.xxx.xxx #你的广播址

ONBOOT = yes

然后运行 /etc/sysconfig/network-scripts/ifup eth0 启动。
