什么（代码=已退出，状态=1 / 失败）？服务 nginx 状态

我刚刚发现 nginx 状态有错误。这个错误不会阻止任何事情。它没有给我带来问题。一切都正确启动。Nginx -t 它没有返回任何语法错误。

我只在 nginx status 中看到它。服务 nginx status。或 Systemctl status nginx

错误：

發生錯誤。

我只是这样做了：

Service nginx stop

然后从新系统开始：

systemctl start nginx

现在他却吞噬了我。

我看到的唯一不好的事情是

PID from file /run/nginx.pid: Invalid argument

但全部功能齐全。

答案1

Process: 25343 ExecStop=/sbin/start-stop-daemon --quiet --stop --retry QUIT/5 --pidfile /run/nginx.pid (code=exited, status=1/FAILURE)

这一行表示退出过程失败。（参见--stop其中的选项）。

这仅仅意味着它无法停止，这很可能意味着它根本没有运行:)

您真正需要担心的唯一事情是，当您尝试启动该服务时却发现它没有运行。
