types support Push/pop, Add/remove, and intersection-set and difference sets, and richer operations, and these operations are atomic. Based on this, Redis supports sorting in a variety of different ways. As with memcached, data is cached in memory to ensure efficiency. The difference is that Redis periodically writes the updated data to disk or writes the modified operation to the appended record file, and
error Because the Redis service is self-booting, it will not start again, so loading the configuration file is a failure. There is also no Redis boot small box (below the picture, slowly looking down), note that the Windows version of the Redis installation, the default boot loaded configuration file is redis.windows

Introduction There is a need to use Redis at work recently, so I have a whim to write a Java client. After two days of effort, the client is now basically molded. Unfortunately, because of the number of REDIS commands, the LZ also needs to slowly expand it to support more commands. Share This article only two purpos
1. Installing RedisRedis does not have an official version of Windows, but the Microsoft Open Technology team (Microsoft Open Tech Group) develops and maintains this Win64 version.I downloaded this version of 3.0: https://github.com/MicrosoftArchive/redis/releasesDownload and then unzip. I unzip here to the D packing directory:1.1 Start the Redis server terminal

number of a node is 6379, then it communicates with other nodes with a port number of 16379. The communication between nodes uses a special binary protocol.For the client, the entire cluster is considered to be a whole, and the client can connect to any node to operate, just as with a single Redis instance, when the client
