</div>
<p><img src="https://img2022.cnblogs.com/blog/1447599/202205/1447599-20220519094733165-902369774.png"></p>
<p> ubuntu 22.04.</p>
<p> </p>
<p>2、进入/etc/netplan/目录，列出该目录下的内容</p>
<div class="cnblogs_code">
<pre><span style="background-color: rgba(0, 255, 0, 1)">cd /etc/netplan/<span style="color: rgba(0, 0, 0, 1)">

<p> </p>
<p> </p>
<p>3、利用vim编辑器打开xxx.yaml文件，进行编辑：</p>
<div class="cnblogs_code">
<pre><span style="background-color: rgba(0, 255, 0, 1)">vim <span style="color: rgba(128, 0, 128, 1)">01</span>-network-manager-all.yaml</span></pre>
</div>
<p>内容如下：（<span style="background-color: rgba(0, 255, 0, 1)">修改网卡名称、IP、网关后保存退出</span>）</p>
<div class="cnblogs_code">
<pre># Let NetworkManager manage all devices on <span style="color: rgba(0, 0, 255, 1)">this</span><span style="color: rgba(0, 0, 0, 1)"> system

</div>
<p><img src="https://img2022.cnblogs.com/blog/1447599/202205/1447599-20220519100726878-1424437783.png"></p>
<p><span style="background-color: rgba(0, 255, 0, 1)"> 格式的缩进很容易出错， 可以直接复制以上模板，只修改网卡名称、IP和网关即可</span>。</p>
<p> </p>
<p>4、开启 systemd-networkd服务（可选）</p>
<div class="cnblogs_code">
<pre><span style="background-color: rgba(0, 255, 0, 1)">sudo systemctl start systemd-networkd</span></pre>
</div>
<p><img src="https://img2022.cnblogs.com/blog/1447599/202205/1447599-20220519101953156-1178199085.png"></p>
<p> </p>
<p> </p>
<p>5、查看systemd-networkd服务状态（可选）</p>
<div class="cnblogs_code">
<pre><span style="background-color: rgba(0, 255, 0, 1)">sudo systemctl status systemd-networkd</span></pre>
</div>
<p><img src="https://img2022.cnblogs.com/blog/1447599/202205/1447599-20220519102119391-2052351580.png"></p>
<p> 说明systemd-networkd服务已经启动。</p>
<p> </p>
<p>6、重启网络服务</p>
<div class="cnblogs_code">
<pre><span style="background-color: rgba(0, 255, 0, 1)">sudo netplan apply</span></pre>
</div>
<p><img src="https://img2022.cnblogs.com/blog/1447599/202205/1447599-20220519095815778-1085608550.png"></p>
<p><span style="background-color: rgba(0, 255, 0, 1)"> 没有报错说明格式正确</span>。</p>
<p> </p>
<p>7、查看设定的IP是否生效</p>
<div class="cnblogs_code">
<pre><span style="background-color: rgba(0, 255, 0, 1)">ifconfig | head -n <span style="color: rgba(128, 0, 128, 1)">3</span></span></pre>
</div>
<p><img src="https://img2022.cnblogs.com/blog/1447599/202205/1447599-20220519095933112-934286772.png"></p>
<p> 设定的IP已生效。</p>
<p> </p>
<p>8、测试网络连接是否正常</p>
<div class="cnblogs_code">
<pre><span style="background-color: rgba(0, 255, 0, 1)">ping -c <span style="color: rgba(128, 0, 128, 1)">3</span> www.baidu.com</span></pre>
</div>
