nginx启动报错,nginx默认80端口被占用解决方案

在win7 32位下，启动nginx，显示如下错误：

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)   

1、打开注册表：regedit

2、找到：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\HTTP

3、找到一个REG_DWORD类型的项Start，将其改为0

4、重启系统
