Ubuntu进入root权限命令——sudo和su命令详解

ubuntu用户管理

sudo 意思就是super-user do,让当前用户暂时以管理员的身份root来执行这条命令。

su (switch user)是用来改变当前用户的,su root,就是将当前用户切换为root,用了su root之后,下面所有的命令就可以不用打sudo了,因为当前用户已经是管理员root了。

root 用户为根用户,也就是 系统管理员 拥有全部权限

一个用户只能拥有一个 GID ,但是还可以归属于其它附加群组

 

用户管理的重要配置文件:

/etc/passwd 用户名 密码位 UID 归属GID 姓名 $HOME目录 登录Shell/etc/shadow 用户名 已加密密码 密码改动信息 密码策略/etc/group 群组名 密码位 GID 组内用户/etc/gshadow 群组密码相关文件,不重要/etc/sudoers 用户名 权限定义 权限可以使用 pwconv 命令创建影子密码,将 /etc/passwd 文件中的密码转换到 /etc/shadow 文件 214 more words
