I used redis 3.0.3 with centos 6.2

Have you config the redis.properties file?
Note that the default host is "localhost" and port 6379.

I had the same problem as you.Finally i debug the source code, and found that there is a bug.
File:RedisConfigurationBuilder.java(line:100)
The orginal code is: jedisConfig.setHost("localhost");
I modified this code to: jedisConfig.setHost(config.getProperty("redis.ip"));
And this solved the problem.

Hi all.

The line "jedisConfig.setHost("localhost");" was indeed wrong but made no difference because the value was lately overwritten by the "host" property from the config file. Moreover, if there was no "host" property "localhost" will be set by default in RedisConfig.

So if you are getting a connection proproblem I would 1st check your host and port are right in your propierties file as @live106 pointed.
