Nginx服务一直不停，怎么办？

我在一台新买的服务器上，装有 CentOS 8 和最新的 Nginx。

我尝试停止 Nginx：

[root@mymachine run]# nginx -s stop
nginx: [error] invalid PID number "" in "/run/nginx.pid"

不工作。

网络仍然有效。我可以用来curl -I http://mysite.com查看输出：

HTTP/1.1 200 OK
Server: nginx/1.14.1

我发现了很多过程：

[root@mymachine run]# ps -aux | grep "nginx"
root       22584  0.0  0.1 156164 11292 ?        S    Sep17   0:03 nginx: worker process
root       22585  0.0  0.1 155836 10832 ?        S    Sep17   0:00 nginx: worker process
root       22586  0.0  0.1 155836  9348 ?        S    Sep17   0:00 nginx: worker process
root       22587  0.0  0.1 155836  9348 ?        S    Sep17   0:00 nginx: worker process
root       22588  0.0  0.1 155836  9348 ?        S    Sep17   0:00 nginx: worker process
root       22589  0.0  0.1 155836  9348 ?        S    Sep17   0:00 nginx: worker process
root       22590  0.0  0.1 155836  9348 ?        S    Sep17   0:00 nginx: worker process
root       22591  0.0  0.1 155836  9348 ?        S    Sep17   0:00 nginx: worker process
root       22592  0.0  0.1 155836  9144 ?        S    Sep17   0:00 nginx: cache manager process
root       26125  0.0  0.0  12108  1080 pts/0    S+   09:11   0:00 grep --color=auto nginx

我应该怎么做才能完全关闭 nginx？

为什么会发生这种情况？

更新为systemctl 状态 nginx.service结果：

[root@mymachine ~]# systemctl status nginx.service
