ubuntu – nginx无法绑定到端口80 ..没有在端口80上运行

我正在尝试在Ubuntu 11.04上设置Nginx.我按照这里的大致指示：http://library.linode.com/frameworks/sinatra/debian-6-squeeze.我知道这是针对Debian的,但我基本上采取了这些步骤然后用Google搜索“如何在ubuntu 11.04中执行x”虽然我确实从他们的库中提取了init脚本.

Starting Nginx: Nginx: [emerg] bind() to 0.0.0.0:80 Failed (98: Address already in use)
Nginx: [emerg] bind() to 0.0.0.0:80 Failed (98: Address already in use)
Nginx: [emerg] bind() to 0.0.0.0:80 Failed (98: Address already in use)
Nginx: [emerg] bind() to 0.0.0.0:80 Failed (98: Address already in use)
Nginx: [emerg] bind() to 0.0.0.0:80 Failed (98: Address already in use)
Nginx: [emerg] still could not bind()

命令：’sudo lsof -i：80’不返回端口80上运行的任何内容.

我如何解决这个或任何可能出错的想法？

我看到Nginx + uWSGI on a fresh Ubuntu install – bind error port 80并尝试重新启动计算机并运行一次,我得到了同样的错误.运行一次之后,我运行了lsof命令.

最佳答案

一种可能性是,由于某种原因,Nginx两次绑定到端口80.

如果它试图这样做,它将失败.一个例子可能是绑定到IPV6和IPV4,或者绑定到公共IP和通配符ip.

检查你的Nginx配置,确保它只绑定一次.
