使用sudo可以在以非root用户登录时临时获得root权限,并执行需要的命令。可以使用sudo的用户可以叫做sudoer。
添加sudoer的方法(假设您已经安装sudo):执行
# visudo
或
# sudoedit
提示:
有些发行版的sudo提供了sudoedit,有的则提供了visudo,功能上基本是一样的。你也可以使用其他编辑器如vi进行编辑/etc/sudoers,但由于文件是只读的,请强制保存(如w!)或去除只读属性再保存。查找
root ALL=(ALL) ALL
在下面加入
%adm ALL=(ALL) ALL
如果sudo时不想输入密码,可以把上句改成:
%adm ALL=(ALL) NOPASSWD: ALL
保存文件,然后执行
#gpasswd -a 用户名 adm
然后这个用户就可以用sudo了。
