提示：出现问题版本为redis-3.2.1.tar.gz

使用其他版本不需要做如下配置，idea、eclipse均连接正常，如：

• redis-3.0.0.tar.gz
• redis-4.0.11.tar.gz

这个问题是由于Redis是在守护状态下运行的，如果不是本地连接，就会报错，解决方法在问题描述中已经给出：

1、检查在linux的redis是否开启：ps -ef | grep redis
错误的状态 root      28465      1  0 06:36 ?        00:00:00 ./redis-server 127.0.0.1:6379    
正确的状态 root      28465      1  0 06:36 ?        00:00:00 ./redis-server *:6379 

2、在linux上连接jedis的链接是否成功  ./redis-cli -h 192.168.66.101 -p 6379

3、修改配置文件redis.conf,并重新启动redis服务

1. 注释 bind 127.0.0.1
2. protected-mode yes 改为 no
3. 重启：先shutdown,后exit，然后重新运行./redis.server -redis.conf

4.以上都没问题，还是连接不成功，查看liunx的防火墙是否关闭
输入：service iptables status
关闭防火墙：service iptables stop
