Ubuntu nginx: [emerg] bind() to 0.0.0.0:80 failed (13: Permission denied)

在Ubuntu 12中启动刚安装好的Nginx，报错：

nginx: [emerg] bind() to 0.0.0.0:80 failed (13: Permission denied)

原因如下：

the socket API bind() to a port less than 1024, such as 80 as your title mentioned, need root access.

所以说：

要么换用户为 root，要么改端口，，，因为是本地开发环境，所以我选择了改端口（8088）！
