ubuntu14下配置静态ip地址

安装系统时添加了两个网卡，安装完成后，网卡信息如下所示

root@ubuntu:~# ifconfigeth0      Link encap:Ethernet  HWaddr 00:0c:29:ae:e7:6a            inet addr:10.180.0.189  Bcast:10.180.255.255  Mask:255.255.0.0          inet6 addr: fe80::20c:29ff:feae:e76a/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:7486 errors:0 dropped:0 overruns:0 frame:0          TX packets:181 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:476030 (476.0 KB)  TX bytes:19795 (19.7 KB)eth1      Link encap:Ethernet  HWaddr 00:0c:29:ae:e7:74            inet addr:10.180.0.191  Bcast:10.180.255.255  Mask:255.255.0.0          inet6 addr: fe80::20c:29ff:feae:e774/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:7375 errors:0 dropped:0 overruns:0 frame:0          TX packets:51 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:453195 (453.1 KB)  TX bytes:8376 (8.3 KB)

想把eth0的ip配置成静态的10.180.141.130

打开网卡配置文件 vi /etc/network/interfaces

添加eth0的配置如下

auto eth0iface eth0 inet staticaddress 10.180.141.130netmask 255.255.255.0gateway 10.180.0.1

保存后，重启网络

sudo /etc/init.d/networking restart

再查看网络配置 ifconfig

root@ubuntu:/etc/network# ifconfigeth0      Link encap:Ethernet  HWaddr 00:0c:29:ae:e7:6a            inet addr:10.180.0.189  Bcast:10.180.255.255  Mask:255.255.0.0          inet6 addr: fe80::20c:29ff:feae:e76a/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:38934 errors:0 dropped:0 overruns:0 frame:0          TX packets:187 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:2371872 (2.3 MB)  TX bytes:20377 (20.3 KB)eth1      Link encap:Ethernet  HWaddr 00:0c:29:ae:e7:74            inet addr:10.180.0.191  Bcast:10.180.255.255  Mask:255.255.0.0          inet6 addr: fe80::20c:29ff:feae:e774/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:38823 errors:0 dropped:0 overruns:0 frame:0          TX packets:95 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:2349037 (2.3 MB)  TX bytes:11238 (11.2 KB)

发现网卡地址并没有变

注意：如果Ubuntu系统采用的是desktop版，由于desktop版安装了NetworkManager，修改完interfaces文档中的内容后，不会生效。需要先修改 /etc/NetworkManager/NetworkManager.conf 文档中的managed参数，使之为true，并重启系统， 然后在修改 /etc/network/interfaces 文件，设置静态IP。这是桌面版和服务器版的不同之处

root@tongfang-virtual-machine:~# cat /etc/NetworkManager/NetworkManager.conf [main]plugins=ifupdown,keyfile,ofonodns=dnsmasq[ifupdown]managed=yesroot@tongfang-virtual-machine:~# 

重启后，发现网卡配置正确了

root@ubuntu:/etc/network# ifconfigeth0      Link encap:Ethernet  HWaddr 00:0c:29:ae:e7:6a            inet addr:10.180.141.130  Bcast:10.180.141.255  Mask:255.255.255.0          inet6 addr: fe80::20c:29ff:feae:e76a/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:2043569 errors:0 dropped:0 overruns:0 frame:0          TX packets:564 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:123158350 (123.1 MB)  TX bytes:65430 (65.4 KB)eth1      Link encap:Ethernet  HWaddr 00:0c:29:ae:e7:74            inet addr:10.180.0.191  Bcast:10.180.255.255  Mask:255.255.0.0          inet6 addr: fe80::20c:29ff:feae:e774/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:20284 errors:0 dropped:0 overruns:0 frame:0          TX packets:232 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:1252816 (1.2 MB)  TX bytes:32046 (32.0 KB)

其实可以采用命令行的方式来配置ip地址

ifconfig eth0 10.180.141.130 netmask 255.255.0.0

查看网卡信息，发现信息正确,只是这种方式重启后网络配置不能保存

root@ubuntu:/etc/network# ifconfigeth0      Link encap:Ethernet  HWaddr 00:0c:29:ae:e7:6a            inet addr:10.180.141.130  Bcast:10.180.255.255  Mask:255.255.0.0          inet6 addr: fe80::20c:29ff:feae:e76a/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:43771 errors:0 dropped:0 overruns:0 frame:0          TX packets:230 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:2662710 (2.6 MB)  TX bytes:27458 (27.4 KB)eth1      Link encap:Ethernet  HWaddr 00:0c:29:ae:e7:74            inet addr:10.180.0.191  Bcast:10.180.255.255  Mask:255.255.0.0          inet6 addr: fe80::20c:29ff:feae:e774/64 Scope:Link          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1          RX packets:43699 errors:0 dropped:0 overruns:0 frame:0          TX packets:104 errors:0 dropped:0 overruns:0 carrier:0          collisions:0 txqueuelen:1000           RX bytes:2646716 (2.6 MB)  TX bytes:11778 (11.7 KB)

至此，ip地址配置完毕。
