nginx: [alert] kill(57200, 1) failed (3: No such process)

Question

当我执行此命令时：

./nginx -s reload

抛出错误：

nginx: [alert] kill(57200, 1) failed (3: No such process)

当我打开 nginx.pid 文件时：

vim /usr/loca/nginx/logs/nginx.pid

进程 id 是：57200。但是当我检查 nginx 进程时，它没有主进程，输出是：

    [root@localhost logs]# ps -aux|grep nginx

怎么了？如何解决这个问题呢？nginx 版本是 1.10.2。

Answer 1

我在 nginx 1.10.2 上也遇到了类似的问题。

而不是./nginx -s reload，我曾经./nginx启动 nginx 并解决了这个问题。
