LINUX怎么用usermod设置主组和附加组?
<p>今天我们就来看看LINUX中usermod来设置主组和附加组的方法，很简单，请看下文详细教程。</p><p>1、打开LINUX UBUNTU操作系统，找到终端并且打开窗口。</p>

<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/2018112612315498.jpg" /></p>
<p>2、输入<strong>id</strong>后可以查看所有的<span style="color: #ff0000"><strong>主组和附加组</strong></span>。</p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/2018112612315499.png" /></p>
<p>3、passwd文件这里显示第二个1000是<strong>主组的编号</strong>。</p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/20181126123154100.png" /></p>
<p>4、这里一目了然study这个用户的<strong>附组权限。</strong></p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/20181126123154101.png" /></p>
<p>5、<strong>chris</strong>这个用户没有附加组<span style="color: #ff0000"><strong>sudo的权限</strong></span>，创建不了用户。</p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/20181126123154102.png" /></p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/20181126123154103.png" /></p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/20181126123154104.png" /></p>
<p>6、大写的G可以添加<strong>附加组。</strong></p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/20181126123154105.png" /></p>
<p>7、这里查看，sudo权限就有两名用户了。</p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/20181126123155106.png" /></p>
<p>8、但是这里还是不行，因为要退出再连接才行。</p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/20181126123155107.png" /></p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/20181126123155108.png" /></p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/20181126123155109.png" /></p>
<p>9、这个时候就成功添加权限了。</p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/20181126123155110.png" /></p>
<p>10、而<span style="color: #ff0000"><strong>-g</strong></span>是用来更改主组的。</p>
<p align="center"><img alt="" src="https://img.jbzj.com/file_images/article/201811/20181126123155111.png" /></p>
