nginx的：EMERG] bind（）的，以0.0.0.0:80失敗（98：地址已在使用），甚至使用殺死進程端口80

Question

我想，如下所示nginx的啓動後：

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() 

在此之後EasyEngine tutorial，我試着用fuser -k殺死使用端口80的過程：

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

然而，之後重新運行sudo /usr/sbin/nginx我得到完全相同的錯誤消息。

我試過幾個其他的「診斷」描述here，使用fuser，lsof -i和netstat：

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命令給出的結果，但是我無法推斷來自它的進程ID。

關於如何讓nginx工作的任何想法？

Answer 1

您應該運行此

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

它會告訴你進程ID

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

2063/Apache2的 - PID /進程名
