Redis introduction and Linux installation Redis

Introduction to Redis

Redis is an open source, advanced key-value store and a suitable solution for building high-performance, scalable web applications.

Redis has three main features that make it superior to other key-value data storage systems-

Redis keeps its database completely in memory and uses only disk for persistence.
Compared with other key-value data storage, Redis has a relatively rich set of data types.
Redis can copy data to any number of slaves.

Redis installation

Redis is developed based on C language, so you need to install C language environment

Enter the command in linux: yum install gcc-c ++

If prompted to download, enter y

Sign of successful installation

Put the downloaded redis compressed package (.tar.gz file) into the linux system, I put it in the / usr / local / software directory

Go to the directory where the compressed package is located and unzip the file to the / opt / modules directory. The difference between opt and usr is the location of opt to store large service software, so install redis to this directory
tar -zxvf redis-3.2. 5 .tar.gz -C / opt / modules

After the secret conversion is successful, a bin directory will appear in the installation directory

Enter the bin directory

Start redis-server

Sign of successful startup

Set up backend startup

Directly execute redis-server and start the front end. Once the client window is closed, this service will close the client, and no other commands can be executed in the client window

So you need to set up the back-end startup, start redis-server through the configuration file

File: The location is where the installation package was unzipped: redis.config

Set redis.conf configuration

The default is 127.0.0.0 modified to its own hostname name or ip name
