spring cloud 配置中心的部署

今天部署spring cloud 的配置中心,遇见的问题如下:
因为项目是在Windows环境下开发的,Windows环境也是我的常用环境,所以git的一些配置是比较完善的,配置中心搭建完成后,在Windows环境上跑起来,各种测试都没有任何问题,然后就把配置中心放置在Linux环境下启动,项目是起来了,但是问题来了:::其他的服务不能访问配置中心的内容,各种方法的尝试,最终无果
接下来想到因为是连的git仓库,会不会是需要安装一下git,然后就yum install git,安装了git,接着重新启动项目,然而没什么用
再接着想到,Windows环境下配置了ssh公钥,会不会和这个有关,然后就配置了一下ssh公钥,在重启重试,还是不行,但是这一次出现了一个异常信息

这下,找到了关键的地方了.Are you sure you want to continue connecting?
最简单的解决办法,因为上边已经安装了一个Git,所以可以直接找一个你的远程仓库clone一下,这时的提示信息中会有如下内容

Are you sure you want to continue connecting (yes/no)? yes

输入yes回车,在重新启动项目,ok!
