nginx：[emerg] bind（）到0.0.0.0:80失败（98：地址已在使用中），即使在使用端口80终止进程后也是如此

Question

我正在尝试如下启动nginx：

kurt@kurt-ThinkPad:~$ which nginx
/usr/sbin/nginx
kurt@kurt-ThinkPad:~$ sudo /usr/sbin/nginx
nginx: [emerg] bind() to 0.0.0.0:80 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 0.0.0.0:80 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 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()

遵循此EasyEngine教程之后 ，我尝试使用带有融合 fuser -k端口80 终止进程：

kurt@kurt-ThinkPad:~$ sudo fuser -k 80/tcp
80/tcp:              31924 31925 31926

但是，在重新运行sudo /usr/sbin/nginx我得到了完全相同的错误消息。

我已经尝试过使用fuser ， lsof -i和netstat 在这里描述的其他两个“诊断”：

kurt@kurt-ThinkPad:~$ fuser 80/tcp
kurt@kurt-ThinkPad:~$ lsof -i :80 | grep LISTEN
kurt@kurt-ThinkPad:~$ netstat -tulpn | grep --color :80
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      -               
tcp        0      0 127.0.0.1:8080          0.0.0.0:*               LISTEN      -               
tcp        0      0 0.0.0.0:8060            0.0.0.0:*               LISTEN      -      

只有netstat命令给出结果，但是我无法从中推断出进程ID。

关于如何使Nginx工作的任何想法？

Answer 1

你应该运行这个

user@user ~ $ sudo netstat -tulpn | grep --color :80

它将显示您的进程ID

tcp6       0      0 :::80                   :::*                    LISTEN      2063/apache2

2063 / apache2 – PID /进程名称
