nginx 启动不了 nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)

[Nickyu]

是按照这个教程来的
https://coderwall.com/p/dgwwuq
但是安装完nginx后启动就出现这个错误
Nicks-MacBook-Pro:~ Nick$ sudo nginx
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)

这是nginx.conf配置内容

#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;

请问，这要怎么解决啊

先看看你80端口上跑了什么东西……

只有这个，但是kill掉后重启还是这样啊

[582033]

还好我看懂了already in use...

@Nickyu netstat -tnpl 看看是什么东西在80端口运行

[phperstar]

先ps aux 看一下有没有未结束的进程，然后 pgrep php-cgi | xargs kill -s 9 ，最后重启

[Nickyu]

@582033 没看到啊,我用这个命令看的时候terminal是这么显示的
Nicks-MacBook-Pro:~ Nick$ sudo lsof -i:80

[582033]

你怎么重启的？ `sudo nginx` ?

[Nickyu]

@582033 nginx -s reopen ,有问题？

[ooxxcc]

mac下使用80端口似乎需要sudo

[Nickyu]

@ooxxcc 我加了，不加不行的，然后就这样了，Nicks-MacBook-Pro:~ Nick$ sudo -s reopen
/bin/bash: reopen: command not found
Nicks-MacBook-Pro:~ Nick$ sudo nginx -s reopen
nginx: [alert] kill(11536, 30) failed (3: No such process)
搞不懂啊

[ooxxcc]

sudo nginx

[freetg]

@Nickyu http就是80

[Nickyu]

@ooxxcc 没用，返回的是failed 48:already in use，好像是nginx自己占用端口，但是kill 掉80端口重启nginx还是这样

[Nickyu]

@ooxxcc 浏览器输入local地址后还是404 not found nginx／1.6.1

[ooxxcc]

@Nickyu nginx默认的配置文件应该是 http://localhost:8080/，我这边测试可以

试试sudo killall nginx ; sudo nginx -c /xxx/xxx/nginx.conf

nginx version: nginx/1.6.1
Usage: nginx [-?hvVtq] [-s signal] [-c filename] [-p prefix] [-g directives]

Options:
-?,-h : this help
...
-s signal : send signal to a master process: stop, quit, reopen, reload
-p prefix : set prefix path (default: /usr/local/Cellar/nginx/1.6.1/)
-c filename : set configuration file (default: /usr/local/etc/nginx/nginx.conf)

80端口被占用了？如果centos的话记得卸载Apache

[syaokun219]

感觉像是一个很普通的问题

[itfanr]

请问楼主后来解决了吗？
