我刚刚创build了一个Ubuntu服务器。 我试图安装Nginx，但我得到了错误。

这是一个全新的服务器，除了更新apt-get，我没有configuration任何东西。
nginx: [emerg] socket() [::]:80 failed (97: Address family not supported by protocol)
Nginx尝试启动，并连接到[::]：80，但不能。 可能是因为在机器上禁用了IPv6。 启用IPv6或更改nginxconfiguration。 在configuration文件/etc/nginx/nginx.confsearch这一行：
listen [::]:80 default_server;
并发表评论：
# listen [::]:80 default_server;
重新启动nginx：
systemctl nginx restart
或者，如果这给错误，它不运行：
systemctl nginx start
然后再次运行安装命令。
