Introduction

Redis is a popular open-source database management system known for its high performance and diverse features, widely used in distributed systems. This article provides a detailed guide on how to install and configure Redis on Rocky Linux / CentOS 8, covering everything from basic installation to advanced configuration to ensure optimal performance and security.

What is Redis Server?

Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker from https://redis.io/

Install configure Redis on Rocky Linux / Centos 8

Step 1: Update your Rocky Linux/Centos 8 Server 

sudo dnf -y update

I will use remi release to install Redis module

  sudo dnf install -y https://rpms.remirepo.net/enterprise/remi-release-8.rpm

   sudo dnf module list redis

Enable redis 6

   sudo dnf module enable redis:remi-6.2 -y

In Redis Server.

   appendonly yes
   appendfilename "appendonly.aof"

  sudo systemctl restart redis

  $ redis-cli
  127.0.0.1:6379> auth devopsroles.com
  127.0.0.1:6379> INFO

Performing Redis Benchmarking against local redis to test its performance. For example, run the benchmark with 20 parallel connections

  $ redis-benchmark -h 127.0.0.1 -p 6379 -n 10000 -c 20 -a devopsroles.com

Conclusion

After completing these steps, you will have successfully installed and configured Redis on Rocky Linux / CentOS 8. Testing and benchmarking Redis ensures your system operates efficiently and reliably. With Redis, you can leverage powerful features to enhance performance and scale your applications. thank you for reading the huuphan.com page!
