我试图在Ubuntu 11.04上安装nginx。 我大致遵循这里find的方向： http : //library.linode.com/frameworks/sinatra/debian-6-squeeze 。 我知道这是Debian，但我基本上采取了这些步骤，然后Googlesearch“在Ubuntu 11.04如何做x”虽然，我从他们的图书馆拉的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'在端口80上不返回任何内容。
如何解决这个或任何想法可能出错？
我看到一个新的Ubuntu安装Nginx + uWSGI – 绑定错误端口80，并尝试重新启动计算机并运行一次，我得到相同的错误。 运行一次之后，我运行了lsof命令。
UPDATE
sudo netstat -ltnp返回：

nestat -a回报：

一种可能性是，由于某种原因，nginx绑定到端口80两次。
如果它试图做到这一点将失败。 一个例子可能是绑定到IPV6和IPV4，或绑定到公共IP和通配符IP。
检查你的nginxconfiguration，确保它只绑定一次。
尝试：
http{ server { listen 80; listen localhost; # <- probably will fix your problem location / { root /data/www; } location /images/ { root /data; } } }
