telnet: connect to address 192.168.240.131: Connection refused解决：关闭linux防火墙，记得要关闭开机启动，如何关闭请参考，配置：-bash : xxx : command not found 新安装Linux后，安装一些必须软件（持续更新……）
Could not connect to Redis at 192.168.240.131:6379: Connection refused解决：需要将redis.conf中的bind 127.0.0.1注释掉，这样才不是唯一只绑定本地访问。

成功连接后，操作时会报错：

(error) DENIED Redis is running in protected mode because protected mode is enabled, no bind address 
was specified, no authentication password is requested to clients. In this mode connections are only 
accepted from the loopback interface. If you want to connect from external computers to Redis you may 
adopt one of the following solutions: 1) Just disable protected mode sending the command 
'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host 
the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. 
Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected 
mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then 
restarting the server. 3) If you started the server manually just for testing, restart it with the 
'--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need 
to do one of the above things in order for the server to start accepting connections from the outside.

解决：'CONFIG SET protected-mode no'这句很明显，我们需要将redis.conf中的protected-mode改为no

Cannot deserialize; nested exception is org.springframework.core.serializer.support.SerializationFailedException:
Failed to deserialize payload. Is the byte array a result of corresponding serialization for DefaultDeserializer?;
nested exception is java.io.EOFException
解决：这个异常是因为序列化和反序列化异常导致的，通常是因为你在redis服务器上手动序列化存储了一个值，然后在代理中进行反序列化获取时报错了。最好就是存取都在代码中完成。
