Question

我很惊讶因为：

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:443 failed (98: Address already in use)

启动Nginx时，所以我认为Nginx或其他在端口上运行。我测试过：

lsof -i :80                         
COMMAND   PID     USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
nginx   13557 www-data    8u  IPv4 100729      0t0  TCP *:http (LISTEN)
nginx   13558 www-data    8u  IPv4 100729      0t0  TCP *:http (LISTEN)

是的，Nginx正在工作，实际上网页正在运行。一切都很完美，但......不是！

怎么可能这个？

service nginx status
[FAIL] nginx is not running ... failed!

没有跑？但我无法启动任何其他实例，因为它正在运行！发生了什么事？

重新启动时相同：

service nginx restart
Restarting nginx: Enter PEM pass phrase:

提前致谢。

检查nginx是否正在运行：

ps aux | grep nginx

如果存在nginx进程，那么它肯定会运行。您使用lsof验证的仅证明80端口被某个进程占用（例如，apache httpd或其他一些http服务器）。如果nginx进程没有运行但是正在使用80端口，这也解释了为什么你不能启动你的nginx。在这种情况下，您需要在进程列表中查找以查看哪个Web服务器已在运行。杀死它并重新启动nginx，它应该可以正常工作。

Nginx运行与否？
