# Jedis所需要的jar包 #

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>3.2.0</version>
    </dependency>

# 连接Redis注意事项 #

禁用Linux的防火墙：Linux(CentOS7)里执行命令
    systemctl stop/disable firewalld.service   
    redis.conf中注释掉bind 127.0.0.1 ,然后 protected-mode no

# 创建测试程序 #
