Linux Ubuntu 启动、连接redis测试

环境说明

Linux OS：Ubuntu server 15.04

Redis：redis-3.0.3.tar.gz(注意：好像redis-3.2.8不提供redis-cli客户端命令操作，当然也有可能是我在同一个窗口操作造成的暂未去再次验证)

Java ：jdk1.8.x

Redis启动后请开启不同Xshell进行操作

请保持Redis窗口活跃性，不要手动退出，以确保redis正常工作，监控其是否运行正常。你如果在启动页面按ctrl+z退出，那么redis会受影响。

还是那句话：保持不同的操作窗口。

操作./src/redis-cli命令窗口：
