如何在 Linux 中不輸入密碼運行 sudo 命令

此設置在 /etc/sudoers
文件中完成,這是使用 sudo 命令的默認安全策略;在用戶許可權指定部分。
重要:在 sudeors
文件中,默認打開的 authenticate
參數用於驗證目的。如果設置了它,用戶必須通過密碼(或其他身份驗證方法)進行身份驗證,然後才能使用 sudo
運行命令。
但是,可以使用 NOPASSWD
(當用戶調用 sudo
命令時不需要密碼)標記來覆蓋此默認值。
配置用戶許可權的語法如下:
user_list host_list=effective_user_list tag_list command_list
其中:
user_list
- 用戶列表或已經設置的用戶別名。host_list
- 主機列表或用戶可以在其上運行 sudo 的主機別名。effective_user_list
- 以該用戶或別名運行的用戶列表tag_list
- 標籤列表,如NOPASSWD
。command_list
- 用戶使用sudo
運行的命令或命令別名列表。
要允許用戶(下面的示例中的 aaronkilik
)使用 sudo
不輸入密碼即可運行所有命令,請打開 sudoers
文件:
$ sudo visudo
添加下面的行:
aaronkilik ALL=(ALL) NOPASSWD: ALL
對於組而言,在組名前面使用 %
字元;這意味著 sys
組的所有成員都可以不用密碼使用 sudo
。
%sys ALL=(ALL) NOPASSWD: ALL
要允許用戶不用密碼使用 sudo
運行指定命令(/bin/kill
),添加下面的行:
aaronkilik ALL=(ALL) NOPASSWD: /bin/kill
下面的行會讓 sys
組成員在使用 sudo
運行命令:/bin/kill
、/bin/rm
時不用輸入密碼:
%sys ALL=(ALL) NOPASSWD: /bin/kill, /bin/rm
不用密碼運行 sudo

配置和其他使用選項,請閱讀我們有更多例子描述的文章,:

With havin so much content do you ever run into any problems of plagorism or copyright violation?
My blog has a lot of exclusive content I’ve either authored myself or outsourced but it
looks like a lot of it is popping it up all over the web without my agreement.
Do you know any methods to help protect against content from being stolen? I’d definitely appreciate it.
