菜鸟学习linu-网络配置

1、查看网络配置  ifconfig

[root@localhost root]# ifconfig

eth0      Link encap:Ethernet  HWaddr 00:0C:29:0F:17:5D

          inet addr:192.168.128.128  Bcast:192.168.128.255  Mask:255.255.255.0

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          RX packets:75 errors:0 dropped:0 overruns:0 frame:0

          TX packets:55 errors:0 dropped:0 overruns:0 carrier:0

          collisions:0 txqueuelen:100

          RX bytes:9826 (9.5 Kb)  TX bytes:7297 (7.1 Kb)

          Interrupt:5 Base address:0x2000

lo        Link encap:Local Loopback

          inet addr:127.0.0.1  Mask:255.0.0.0

          UP LOOPBACK RUNNING  MTU:16436  Metric:1

          RX packets:10 errors:0 dropped:0 overruns:0 frame:0

          TX packets:10 errors:0 dropped:0 overruns:0 carrier:0

          collisions:0 txqueuelen:0

          RX bytes:700 (700.0 b)  TX bytes:700 (700.0 b)

2、重启网络服务

（1）全部重启 service network restart

[root@localhost root]# service network restart

Shutting down interface eth0:                              [  OK  ]

Shutting down loopback interface:                          [  OK  ]

Setting network parameters:                                [  OK  ]

Bringing up loopback interface:                            [  OK  ]

Bringing up interface eth0:                                [  OK  ]

（2）只启动第一块网卡 ifup eth0

[root@localhost root]# ifup eth0

Determining IP information for eth0... done.
