Installation of Redis under Windows is used

Summary

Redis is a key-value storage system. Similar to memcached, it supports storing more value types, including string (string), list (linked list), set (set), Zset (sorted set-ordered collection), and hash (hash type). These data 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 on this basis implements the Master-slave (Master-slave ...). 0. Preface

Because it is the first use, so it is installed and used under Windows, refer to a few blog, the following to organize

1. Installing Redis

Official website: http://redis.io/

Official download: Http://redis.io/download can download different versions as needed

Windows Edition: Https://github.com/MSOpenTech/redis

GitHub resources can be downloaded directly from the zip (this is for students who do not know the friendship tips)

After the download is complete, you can right-click on a hard drive such as D:\Redis\redis-2.6

Under D:\Redis\redis-2.6\bin\release There are two zip packages, one 32-bit, one 64-bit

Extract the D:\Redis\redis-2.6 root directory according to the number of bits in your Windows

2. Start Redis

Turn on the service after entering the Redis directory (note plus redis.conf)

redis-server.exe redis.conf

The Redis service shuts down automatically when this window is to be turned on and off

Redis will automatically save the data to the hard drive so the picture is that I have one more DB loaded from disk when I start the second time.

3. Test use

Also open a command line window into the Redis directory (note to modify your own IP)

redis-cli.exe -h 192.168.10.61 -p 6379

4.Java Development Kit Jedis

Jedis:http://www.oschina.net/p/jedis (Redis's official Preferred Java Development Kit)
