RHEL7.0怎么配置网络IP?RHEL7.0 配置网络IP的三种方法介绍
<p>RHEL7里面的网卡命名方式从eth0,1,2的方式变成了enoXXXXX的格式。 en代表的是enthernet (以太网），o 代表的是onboard (内置），那一串数字是主板的某种索引编号自动生成，以便保证其唯一性。和原先的命名方式对比，这种新的方式比较长，难以记忆，不过优点在于编号唯一，做系统迁移的时候不容易出错。</p><p><strong>1.修改/etc/sysconfig/network-scripts/eno16777736</strong></p>
<p>查看你的网卡名称(本机是eno16777736):</p>
<p># ifconfig </p>
<p>eno16777736: flags=4163 mtu 1500 </p>
<p>inet 192.168.1.100 netmask 255.255.255.0 broadcast 192.168.1.255 </p>
<p>inet6 fe80::20c:29ff:feb8:2b07 prefixlen 64 scopeid 0x20 </p>
<p>inet6 fde0:b912:e3a9:0:20c:29ff:feb8:2b07 prefixlen 64 scopeid 0x0 </p>
<p>ether 00:0c:29:b8:2b:07 txqueuelen 1000 (Ethernet) </p>
<p>RX packets 37 bytes 5428 (5.3 KiB) </p>
<p>RX errors 0 dropped 0 overruns 0 frame 0 </p>
<p>TX packets 62 bytes 8269 (8.0 KiB) </p>
<p>TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 </p>
<p>lo: flags=73 mtu 65536 </p>
<p>inet 127.0.0.1 netmask 255.0.0.0 </p>
<p>inet6 ::1 prefixlen 128 scopeid 0x10 </p>
<p>loop txqueuelen 0 (Local Loopback) </p>
<p>RX packets 134 bytes 10928 (10.6 KiB) </p>
<p>RX errors 0 dropped 0 overruns 0 frame 0 </p>
<p>TX packets 134 bytes 10928 (10.6 KiB) </p>
<p>TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 </p>

<p>红色为需要修改或者添加的内容,保存并退出。</p>
<p>部分释义：</p>
<p>TYPE=Ethernet #网络接口类型 </p>
<p>BOOTPROTO=static #动态为dhcp </p>
<p>DEFROUTE=yes </p>
<p>IPV4_FAILURE_FATAL=yes </p>
<p>IPV6INIT=yes #是否支持IPV6 </p>
<p>IPV6_AUTOCONF=yes </p>
<p>IPV6_DEFROUTE=yes </p>
<p>IPV6_FAILURE_FATAL=no </p>
<p>NAME=eno16777736 #网卡名称 </p>
<p>UUID=72cf53fd-534c-4765-912b-3df575a10a7d </p>
<p>ONBOOT=yes #开启自动启用网络连接 </p>
<p>IPADDRO=192.168.1.20 #设置IP地址 </p>
<p>GATEWAY0=192.168.1.1 #设置网关 </p>
<p>PREFIX0=24 #设置子网掩码 </p>
<p>DNS1=192.168.1.1 #设置DNS </p>
<p>HWADDR=00:0C:29:B8:2B:07 </p>
<p>PEERDNS=yes </p>
<p>PEERROUTES=yes </p>
<p>IPV6_PEERDNS=yes </p>
<p>IPV6_PEERROUTES=yes</p>
<p>重启网卡并测试网络：</p>
<p># systemctl restart network</p>
<p><img alt="ping1" src="https://img.jbzj.com/file_images/article/201702/2017021617021950.jpg" /></p>
<p><strong>2.图形工具nmtui</strong></p>
<p>在终端执行命令：</p>
<p># nmtui</p>
<p><img alt="nmtui1" src="https://img.jbzj.com/file_images/article/201702/2017021617021951.jpg" /></p>
<p><img alt="nmtui2" src="https://img.jbzj.com/file_images/article/201702/2017021617021952.jpg" /></p>
<p>你依然需要重启网卡才能生效，并测试网络。</p>
<p><img alt="ping2" src="https://img.jbzj.com/file_images/article/201702/2017021617021953.jpg" /></p>
<p><strong>3.图形工具nm-connection-editor</strong></p>
<p>终端执行命令：</p>
<p># nm-connection-editor</p>
<p><img alt="nm-connection-editor" src="https://img.jbzj.com/file_images/article/201702/2017021617021954.jpg" /></p>
<p><img alt="nm-connection-editor1" src="https://img.jbzj.com/file_images/article/201702/2017021617022055.jpg" /></p>
<p><img alt="nm-connection-editor3" src="https://img.jbzj.com/file_images/article/201702/2017021617022056.jpg" /></p>
<p>三种方法只要会一种就可以上网，配置你所需要的服务，是不是非常简单啊！</p>
