nginx重启失败提示nginx.pid无法找到

重启nginx：  /usr/local/nginx/sbin/nginx -s reload
报错代码：nginx: [error] open() “/usr/local/nginx/logs/nginx.pid” failed (2: No such file or directory)  （如下图）

解决方法：

1. 重新运行一下/usr/local/nginx/sbin/nginx
2. 重启nginx：/usr/local/nginx/sbin/nginx -s reload

上面办法有些朋友可以解决但大多数据解决不了，于是接着google搜索

看一英文的

issued a nginx -s stop and after that I got this error when trying to reload it.

[error]: invalid PID number "" in "/var/run/nginx.pid"

That /var/run/nginx/pid file is empty atm.

What do I need to do to fix it?

nginx -s reload is only used to tell a running nginx process to reload its config. After a stop, you don't have a running nginx process to send a signal to. Just run nginx (possibly with a -c /path/to/config/file)

于是我用了这方法，也就是

nginx -c /path/to/config/file)  //在我机器上是这样的/alidata/server/nginx/sbin/nginx -c /alidata/server/nginx/conf/nginx.conf
