项目在linux上部署出现redis连接超时问题： java.net.SocketTimeoutException: connect timed out

首先贴出报错信息：

遇到的情况：之前这个redis一直能用，也没改什么东西，就是在昨晚时候突然不能用了，查看日志是报连接超时的错误

但是这样子能用：

1）win能够连接远程linux上的redis，正常使用

2）win中能通过项目使用linux上的redis，正常使用

3）linux中能够通过命令行直接使用redis，正常使用

就是将项目部署到linux上后，通过项目调用redis时，就报来连接超时的错误了。

 

花了一天的时间都在探寻该问题的解决方案（实际上是百度~），网上查到的博客都不能解决该问题。

后面也不知道怀疑哪了，就这样改了一下~

 

将redis中的IP改成 localhost，就可以用了，但是这块不知为什么~

 

 

暂时先这样，后面有时间了再深究一下。
