How to Install Redis on centos

Redis is an open source , in-memory data structure store, used as a database, cache, and message broker. Redis provides data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and streams.

This tutorial explains how to install and configure Redis on a CentOS 7 server.

Prerequisites

Before starting with the tutorial, make sure you are logged in as a user with sudo privileges .

Installing Redis on CentOS 7

The installation is pretty straightforward, just follow the steps below:

1. Start by enabling the Remi repository by running the following commands in your SSH terminal:

   sudo yum install epel-release yum-utils sudo yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
   sudo yum-config-manager --enable remi

2. Install the Redis package by typing:

   sudo yum install redis

3. Once the installation is completed, start the Redis service and enable it to start automatically on boot with:

   sudo systemctl start redis
   sudo systemctl enable redis

   Created symlink from /etc/systemd/system/multi-user.target.wants/redis.service to /usr/lib/systemd/system/redis.service.

   To check the status of the service enter the following command:

   sudo systemctl status redis

   You should see something like the following:

   ● redis.service - Redis persistent key-value database
   Loaded: loaded (/usr/lib/systemd/system/redis.service; enabled; vendor preset: disabled)
   Drop-In: /etc/systemd/system/redis.service.d
           └─limit.conf
   Active: active (running) since Sat 2018-11-24 15:21:55 PST; 40s ago
   Main PID: 2157 (redis-server)
   CGroup: /system.slice/redis.service
           └─2157 /usr/bin/redis-server 127.0.0.1:6379Copy

Congratulations, at this point you have Redis installed and running on your CentOS 7 server.
