Nginx错误处理方法: bind() to 0.0.0.0:80 failed

Nginx启动失败原因：

1、进入 nginx-1.12.1\logs 路径下，打开error.log文件，发现有以下错误日志

2017/09/19 11:07:26 [emerg] 5580#3332: bind() to 0.0.0.0:80 failed (10013: An
attempt was made to access a socket in a way forbidden by its access
permissions)

2017/09/19 11:09:35 [emerg] 7552#7556: bind() to 0.0.0.0:80 failed (10013: An
attempt was made to access a socket in a way forbidden by its access
permissions)

2、错误原因是绑定80端口错误，说明80端口被占用，nginx绑定失败。

解决办法：

1、kill掉占用80端口的程序，再次启动nginx

2、如若占用80端口的服务/程序不能关闭，则更改nginx监听的端口号，操作方法：打开nginx.conf文件，将监听的端口80
修改为非80短剑，重新启动即可。
