From June 2015, the development of Redis was sponsored by Redis Labs, while from May 2013 to June 2015, its development was sponsored by Pivotal. Until May 2013, its development was sponsored by VMware. According to the monthly ranking website DB-Engines.com, Redis is the most popular key-value pair storage database.

Redis has the following characteristics:

1.Redis supports the persistence of data. It can keep the data in memory on disk and can be loaded and used again when rebooting without causing data loss.

2.Redis supports mapping between five different data structure types, including data of simple key/value types, as well as storage of data structures such as list,set,zset,hash

3.Redis supports data backup in master-slave mode

Redis has the following functions:

1. Memory storage and persistence: redis supports writing data in memory to the hard disk asynchronously, which persists without affecting the continuation of service.

Redis installation

The installation of Redis for Windows is very simple on the whole, and there are many tutorials on the Internet. Considering that most of the usage scenarios of Redis are on Linux, I will not introduce the installation of Windows here. Friends can search on their own if they are interested. Let's take a look at how to install Redis on Linux.

Environment:

CentOS7

Redis4.0.8

1. First download Redis, download address https://redis.io/, download redis-4.0.8.tar.gz and put it in our Linux directory / opt

Under the 2./opt directory, decompress the file and decompress the command: tar-zxvf redis-4.0.8.tar.gz, as follows:

3. After the decompression, the folder: redis-4.0.8 appears, and go to this directory: cd redis-4.0.8

4. Execute the make command in the redis-4.0.8 directory to compile

5. If you continue to execute make install to install after the make is completed

OK, at this point, our redis is installed successfully.

6. Before we start, we need to make a simple configuration: modify the redis.conf file, change the daemonize no in it to yes, and let the service start in the background, as follows:

7. Start, start redis with the redis-server redis.conf command, as follows:

8. test
