CentOS 如何设置缺省网关

假设CentOS缺省网关是74.86.49.129，通常做法

# vi /etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=wan.nixcraft.in
GATEWAY=74.86.49.129

# /etc/init.d/networking restart

根据网卡设置路由的方法是编辑 /etc/sysconfig/network-scripts/route-eth* 文件，

Open /etc/sysconfig/network and append

GATEWAY=eth0.gateway.IP.address

Open /etc/sysconfig/network-scripts/route-eth1 and add routing for eth1 and restart it. For example:

202.54.1.2/29 via 202.54.2.254

Also, set static route for /etc/sysconfig/network-scripts/route-eth0:

10.1.2.3/8 via 10.10.38.95

Do not add gateway entries to /etc/sysconfig/network-scripts/ifcfg-eth1 and /etc/sysconfig/network-scripts/ifcfg-eth0
