Linux 安装操作系统后添加网卡

1.Linux 安装操作系统后添加网卡

1） root下执行：start_udev

2） vi /etc/udev/rules.d/70-persistent-net.rules 查看新加网卡的mac地址

# PCI device 0x14e4:0x1657 (tg3)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="28:80:23:9b:4f:29", ATTR{type}=="1", KERNEL=="eth*", NAME="eth6"

# PCI device 0x14e4:0x1657 (tg3)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="28:80:23:9b:4f:28", ATTR{type}=="1", KERNEL=="eth*", NAME="eth7"

# PCI device 0x14e4:0x1657 (tg3)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="28:80:23:9b:4f:2a", ATTR{type}=="1", KERNEL=="eth*", NAME="eth5"

# PCI device 0x14e4:0x1657 (tg3)

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="28:80:23:9b:4f:2b", ATTR{type}=="1", KERNEL=="eth*", NAME="eth4"

3）cp ifcfg-eth0 ifcfgeth4

删除uuid行,修改HWADDR为rules.d内的mac地址，修改BOOTPROTO=static

DEVICE=eth4

HWADDR=28:80:23:9B:4F:2b

TYPE=Ethernet

ONBOOT=yes

NM_CONTROLLED=no

BOOTPROTO=none

USERCTL=no

PEERDNS=yes

IPV6INIT=no

4）重启服务器

2.添加静态路由到开机启动

cd /etc/sysconfig/network-scripts/

mkdir route-eth1

vi route-eth1 添加如下：

168.0.0.0/8 via 168.160.60.31 dev eth1

3.手动添加静态路由

route add -net 168.0.0.0 netmask 255.0.0.0 gw 168.160.60.1
