永久改动redhat的default route

1，能够用route命令暂时改动：

route add default gw <gateway ip>

2, 通过改动/etc/sysconfig/network 文件永久改动：

脚本：

#!/bin/sh

#configure default gw

#   $1 is ip of gateway



defgw=$1

sed -i "s/NETWORKING.*/NETWORKING=yes/" /etc/sysconfig/network

sed -i "s/HOSTNAME.*/HOSTNAME=`hostname`/" /etc/sysconfig/network

echo "GATEWAY=$defgw" >> /etc/sysconfig/network

service network restart

事实上终于的/etc/sysconfig/network的格式是：

~]# cat /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=c902f02x44

GATEWAY=60.0.0.202

然后重新启动network服务：service network restart
