Caused by: io.netty.channel.ConnectTimeoutException: connection timed out: /192.168.43.129:6379这里讲解是连接远程服务器的，我连接的是阿里云的服务器，
1，把application.yaml中的Redis的主机配置给改一下，改成自己阿里云服务器的公网ip地址
2，
找到要修改的redis的配置文件 redis.conf
然后：vim redis.conf
修改 protected-mode yes 改为：protected-mode no
注释掉 #bin 127.0.0.1
前提是把防火墙给打开了 ，还有6379 这个端口号也给打开来
3，最后一定要重启项目是后端的项目不是前端！！！
