问题排查步骤如下：

1、保证 java程序端与 redis服务端相互ping 通

a) 本地 DOS 去 ping远程服务器IP

b) 远程服务器ping 本地IP

2、修改Redis服务器配置文件 (我这里是 make install 安装)

vi /etc/redis.conf

其中有两处 bing 127.0.0.1 全部用“#”注释掉

3、重启Redis-server

先查看当前Redis 进程

退出redis-cli，也可以kill redis-cli 进程

停止服务：redis-server shutdown 或 redis-cli shutdown

开启服务：redis-server /etc/redis.conf

4、测试

可以先在本地DOS下进行连接访问，首先要进入本地Redis安装目录下

 如果测试通过，就可以进行java程序连接了
