進(jìn)入/etc/sysconfig/network-scripts。找到ifcfg-eth0.編輯它如下：

DEVICE   =   eth0

ONBOOT   =   yes

BOOTPROTO   =   static

IPADDR=   10.9.100.221(你需要的固定ip)

NETMASK=255.0.0.0

GATEWAY=10.255.255.254

#/etc/resolv.conf

nameserver 202.109.14.5

nameserver 202.96.209.5

search localdomain

改了以后再運(yùn)行/etc/init.d/network   restart

/etc/rc.d/init.d/network   restart

需要重啟網(wǎng)絡(luò)服務(wù)：service network restart     或/etc/init.d/network restart

防火墻關(guān)閉的方法：service iptables stop

service network restart.的時候，出現(xiàn)禁用 IPv4 包轉(zhuǎn)送： net.ipv4.ip_forward = 0。后來在
# vi /etc/sysctl.conf
net.ipv4.ip_forward = 1
保存
# sysctl -p
net.ipv4.ip_forward = 1
