我的sudoers.d/nginx文件中有以下内容：
deployer ALL=NOPASSWD: /etc/init.d/nginx reload
如果我以 sudo 身份运行命令，这会起作用：
$ sudo /etc/init.d/nginx start
[sudo] password for deployer:
Sorry, user deployer is not allowed to execute '/etc/init.d/nginx start' as root on graduation.
但是，当我以非 sudo运行命令时，似乎 sudoers 被通过了。该命令仍然不起作用，但这是因为其他所有权错误，而不是 sudoers 中的限制：
$ /etc/init.d/nginx start
nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (13: Permission denied)
