网卡配置路径 :/etc/sysconfig/network-scripts/ifcfg-interface-name

ifconfig XX up ;ifconfig XX down

ifup XX ;ifdown XX

====================================================================

em2专线配置

DEVICE=em2

em1:略

==================================================================

添加路由:

访问9.234.5.X 都走gw 144.33.6X.66 这个网关则用专线的配置就起作用了

默认访问走电信的 default网关
