环境

Deepin 15.11

创建一个新用户

使用adduser创建一个用户，用户名为user01

bob@bob-PC:~$ sudo adduser user01
Adding user `user01' ...
Adding new group `user01' (1001) ...
Adding new user `user01' (1001) with group `user01' ...
Creating home directory `/home/user01' ...
Copying files from `/etc/skel' ...
Enter new UNIX password: 
Retype new UNIX password: 
passwd: password updated successfully
Changing the user information for user01
Enter the new value, or press ENTER for the default
	Full Name []: user01
	Room Number []: 
	Work Phone []: 
	Home Phone []: 
	Other []: 
Is the information correct? [Y/n] Y

添加user01这个用户到sudo组里面

sudo组的所有成员都在Deepin系统上授予sudo和root访问权限。因此，要将刚刚创建的user01用户添加到sudo组，请运行以下命令：

bob@bob-PC:~$ sudo adduser user01 sudo
Adding user `user01' to group `sudo' ...
Adding user user01 to group sudo
Done.

使用id命令查看一下用户是否添加到sudo组了

bob@bob-PC:~$ id user01
uid=1001(user01) gid=1001(user01) groups=1001(user01),27(sudo)
测试sudo用户账号

现在user01用户使用ssh登录到本机测试

bob@bob-PC:~$ ssh user01@localhost
The authenticity of host 'localhost (127.0.0.1)' can't be established.
ECDSA key fingerprint is SHA256:TKkqZwt9OzPaVSwSkFoLXtAFwnU4aKMG7T8QyF2fPKw.

user01@localhost's password:
