关于eclipse连接redis
1
首先在linux中进入redis：cd/路径名/redis
启动redis：bin/redis-server redis.conf（redis.conf可不写）
打开eclipse并创建一个maven项目（不懂得可以自行百度如何创建一个maven项目）
1）创建好的项目如下：
2）打开pom.xml添加jedis依赖（可去(http://mvnrepository.com/tags/maven)下载依赖）
3）创建一个class类
4）点击运行
5.其中运行时可能会报错
解决方法：
配置下防火墙 开一个6379端口权限
[[email protected] ]# firewall-cmd --zone=public --add-port=6379/tcp --permanent
[[email protected] ]# firewall-cmd --reload
继续运行 还是报错 连接超时 错误；
我们配置下 redis配置文件
[[email protected] redis]# vi /usr/local/redis/redis.conf
这里绑定了本机，我们把这个备注掉；
bind 127.0.0.1
配置完后
[[email protected] redis]# ./bin/redis-cli shutdown
[[email protected] redis]# ./bin/redis-server ./redis.conf
要重启下redis服务；
继续运行 又报错了
Exception in thread “main” redis.clients.jedis.exceptions.JedisDataException: 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.

---------------------
这个是因为远程连接redis redis自我保护 拒绝访问；
解决方法：
设置redis连接密码
进入客户端
[[email protected] redis]# ./bin/redis-cli
127.0.0.1:6379> config set requirepass 123456
设置密码 123456
127.0.0.1:6379> quit
[[email protected] redis]# ./bin/redis-cli
127.0.0.1:6379> auth 123456
OK
