用户和用户组

useradd(8), userdel(8) 和 usermod(8) 命令分别用来添加、删除和修改用户。passwd(1)命令用来修改密码。

groupadd(8) 、 groupdel(8) 和 groupmod(8) 命令分别用来添加、删除和修改组。groups(1) 命令列出一个用户所属的所有组。

默认 shell

用户的默认shell可以用 chsh(1) 来更改。

$ chsh -s <shell> <user_name>

<shell> 必须是指定的 shell 的路径 /etc/shells 或者输出 chsh -l，它提供了已安装 shell 的列表。

sudo(8) 是默认安装的。但可能没有根据您的需要进行适当配置。如果你想使用它，请配置 sudo。。

以 root 身份使用 visudo(8) 来编辑 sudoers(5) 文件。

请取消注释该行

#%wheel ALL=(ALL) ALL

然后将用户添加到 wheel 用户组.
