ubuntu - 无法重启 nginx 网络服务器

Question

我有一个 DigitalOcean 液滴，在将 laravel 应用程序投入生产后，我尝试了以下命令:

sudo systemctl 重新加载 nginx

但我得到这个错误:

Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.

我跑了 sudo nginx -t 看看是否有错误，但 conf 和语法没问题，之后我跑了:

须藤纳米/var/log/nginx/error.log

我得到了这个:

知道为什么我无法重新启动我的网络服务器，我的网络仍然可见，但我似乎无法重新启动或重新加载 nginx。

似乎是 /run/nginx.pid 的问题由于某种原因，这是空的。

首次检查流程ps -ef | grep nginx为 nginx 找到三个根进程(在我的情况下为 7388)

root@keybu:/var/www/keybu_production#  ps -ef | grep nginx
root      2314  9443  0 21:28 pts/0    00:00:00 grep nginx
root      7388     1  0  2019 ?        00:00:00 nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
nginx    23709  7388  0 Jan15 ?        00:00:04 nginx: worker process

然后杀死它:

kill -9 7388

检查是否没有运行 nginx 进程，如果它也被杀死。

然后重启 nginx service nginx start

第二种解决方案是将进程的 ID 号写入 /run/nginx.pid。但还没有测试
