请问我在阿里云买服务器 用什么配置的呢？
PHP运行环境(CentOS)
php/java多语言开发环境
Java运行环境(Ubuntu)
Windows Server 2008
Windows Sever 2012

已经解决，购买的时候我弄错防火墙了，导致80端口没有打开

root@10-23-202-21:/var/www# git clone git@github.com:DPPCoder/HTMl-TEST.git HTML

Please make sure you have the correct access rights
and the repository exists.

购买后 访问外网ip 一直正在连接 或者响应时间过长。
