推荐答案

nginx 可能无法与用户 root 一起运行，而这正是使用 systemctl .因此，您应该使用 sudo 执行命令.

Most probably nginx doesn't run with user root which is what you need to use systemctl. Therefore you should execute your command using sudo.

现在，有多种方法可以使用具有 root 特权的Web服务器运行命令:

Now there are different ways of running a command from web-server with root privileges:

• 使用强烈劝阻的用户 root 运行 nginx ，出于明显的安全原因
• 仅将此特定命令作为在此处描述
• 写一个功能有限的bash脚本，如此处所述

• Run nginx with user root which is highly discouraged for obvious security reasons
• Add only this specific command to sudoers as described here in order to run it with root privileges without any password prompt
• Pass your root password through echo as described here
• Write a bash script with limited functions as described here

但是，当然，您可能会在寻找其他东西.

But of course you might find something else searching on for it.
