How to install Redis on Centos7

Introduction

Redis is an open source (BSD licensed), in-memory data structure store used as a database, cache, and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperlogs, geospatial indexes with radius queries and streams. Redis has built-in replication, Lua scripts, LRU evictions, transactions and different levels of disk durability, and provides high availability through Redis Sentinel and automatic partitioning using Redis Cluster.

What is redis?

Memory-based key-value database supports automatic/manual persistence.

Performance:

The following is the official benchmark-mark data:

The test was completed with 50 concurrent executions of 100,000 requests.

The value set and obtained is a 256-byte string.

Result: The reading speed is 110000 times/s and the writing speed is 81000 times/s

# -p Make sure the directory name exists, if not, create one

mkdir -p /home/software/redis

# -z: with gzip attribute, -x: decompression, -v: display all processes, -f: use the file name. Remember, this parameter is the last parameter, and can only be followed by the file name

tar zxvf redis-3.0.6.tar.gz

cd redis-3.0.6

# make is used for compilation. It reads instructions from the Makefile and then compiles

# make install is used for installation. It also reads instructions from the Makefile and installs it to the specified location. PREFIX selects the directory to be installed

make && make PREFIX=/home/software/redis install

Copy the configuration file and start

cd redis-5.0.5/

cp redis.conf /home/software/redis/bin
