我们在 systemd 中运行 nginx（在端口 8080 上），CentOS 7.7但无法停止它 - 没有错误，它只是继续运行或重生。
我们已经尝试过了sudo systemctl stop，sudo systemctl disable但是kill它仍然继续运行。

禁用并停止
[myuser@myhost gateway]$ sudo systemctl disable gateway
Removed symlink /etc/systemd/system/multi-user.target.wants/gateway.service.
[myuser@myhost gateway]$ sudo systemctl stop gateway
仍在运行
[myuser@myhost gateway]$ sudo systemctl status gateway

对我来说，它看起来是不活动的（=死了、停止了，不管你喜欢怎么称呼它）？
编辑：看来该过程可能仍在进行中：
root 20990 0.0 0.0 59080 1388 ? Ss 13:04 0:00 nginx: master process /usr/sbin/nginx -c /prg/nginx/conf/gateway.con
您可以尝试使用 kill 命令手动将其杀死，如果 SIGTERM 不起作用，请尝试 SIGKILL
kill -SIGTERM <process id, 20990 in this case>
