nginx啓動報錯,nginx默認80端口被佔用解決方案

在win7 32位下，啓動nginx，顯示如下錯誤：

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、打開註冊表：regedit

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

3、找到一個REG_DWORD類型的項Start，將其改爲0

4、重啓系統
