Ubuntu配置网卡IP地址

<p>Ubuntu Desktop14.04 &nbsp;，在window7 下的vmware14虚拟机中</p>
<p>cat &nbsp;/etc/network/interfaces</p>
<p>默认已经有lo: 系统给定的网络回环接口</p>
<p>eth0的配置（Ubuntu Desktop14.04）</p>
<p>1. &nbsp;cd &nbsp;/etc/network</p>
<p>&nbsp; &nbsp; vim &nbsp;interfaces</p>
<p>&nbsp;</p>
<p>2. &nbsp;键入如下命令：</p>
<p>&nbsp; &nbsp; auto &nbsp;eth0</p>
<p>&nbsp; &nbsp; iface &nbsp;eth0 &nbsp;inet &nbsp;static</p>
<p>&nbsp; &nbsp; address &nbsp;192.168.1.1</p>
<p>&nbsp; &nbsp; netmask &nbsp;255.255.255.0</p>
<p>&nbsp; &nbsp; network &nbsp;192.168.1.0</p>
<p>&nbsp; &nbsp; gateway &nbsp;192.168.1.254</p>
<p>&nbsp; &nbsp; broadcast &nbsp;192.168.1.255</p>
<p>&nbsp;</p>
<p>3. &nbsp;添加另一块网卡eth1</p>
<p>&nbsp; &nbsp; auto &nbsp;eth1</p>
<p>&nbsp; &nbsp; iface &nbsp;eth1 &nbsp;inet &nbsp;static</p>
<p>&nbsp; &nbsp; address &nbsp;192.168.1.10</p>
<p>&nbsp; &nbsp; netmask &nbsp;255.255.255.0</p>
<p>&nbsp; &nbsp; network &nbsp;192.168.1.0</p>
<p>&nbsp; &nbsp; gateway &nbsp;192.168.1.254</p>
<p>&nbsp; &nbsp; broadcast &nbsp;192.168.1.255</p>
<p>:wq 存盘退出</p>
<p>&nbsp;</p>
<p>4. &nbsp;重新启动网络服务：</p>
<p>&nbsp; &nbsp; sudo &nbsp;/etc/init.d/networking &nbsp;restart</p>
<p>&nbsp;</p>
<p>5. &nbsp;使eth1生效，激活eth1</p>
<p>&nbsp; &nbsp; ifup &nbsp;eth1</p>
<p>&nbsp;</p>
<p>6. &nbsp;开启网内的访问权限：</p>
<p>&nbsp; &nbsp;sudo &nbsp;ufw &nbsp;allow &nbsp;from &nbsp;192.168.1.250/24</p>
<p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 说明：192.168.1.250为另一台ubuntu server 16.04的IP地址</p>
<p>&nbsp;</p>
<p>7. &nbsp;切换到ubuntu server 16.04虚拟机上，输入命令：</p>
<p>&nbsp; &nbsp;sudo &nbsp;ufw &nbsp;allow &nbsp;from &nbsp;192.168.1.10/24</p>
<p>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 说明：192.168.1.10是ubuntu desktop上刚添加的网卡eth1的IP地址</p>
<p>&nbsp;</p>
<p>8. 两台虚拟机均重新启动</p>
<p>&nbsp;</p>
<p>9. &nbsp;从ubuntu server服务器ping 客户端ubuntu desktop</p>
<p>&nbsp; &nbsp; ping &nbsp;192.168.1.10 &nbsp; &nbsp;连通&nbsp; &nbsp; </p>
<p>&nbsp; &nbsp; 从ubuntu desktop客户端ping 服务器ubuntu server</p>
<p>&nbsp; &nbsp; ping &nbsp;192.168.1.250. 连通</p>
<p>&nbsp;</p>
<p>10. &nbsp;修改客户端ubuntu desktop的eth0的IP地址：</p>
<p>&nbsp; &nbsp; &nbsp;ifconfig &nbsp;eth0 &nbsp;192.168.1.100 &nbsp;netmask &nbsp;255.255.255.0</p>
<p>&nbsp; &nbsp; &nbsp;再看一下是否被修改</p>
<p>&nbsp; &nbsp; &nbsp;ifconfig &nbsp;-a</p>
<p>11. &nbsp;使修改后的IP地址生效：</p>
<p>&nbsp; &nbsp; ifconfig &nbsp;eth0 &nbsp;up</p>
<p>&nbsp; &nbsp; 互相ping &nbsp; 仍然可以ping通</p>
