How to Install Redis on Fedora 36/35/34/33/32

3 min readSep 18, 2022

Welcome to our tutorial on how to Install Redis on Fedora 36/35/34/33/32. Redis is an open-source in-memory data store with optional persistent writes to disk. You can use Redis as a message broker, database or for caching. It supports strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperloglogs, geospatial indexes, and other data structures.

For Ubuntu:

How to Install Redis on Ubuntu / Debian

Install Redis on Fedora 36/35/34/33/32

Follow the steps below to install Redis on Fedora36/35/34/33/32. You can choose to do a clustered setup or a single instance installation. This installation is for a single instance but I’ll cover Redis cluster setup in my next article.

Step 1: Update Fedora system

Start the installation by ensuring your system is up to date.

sudo dnf -y update

Step 2: Install Redis on Fedora36/35/34/33/32

Once your system is updated, install Redis on Fedora by running the command:

sudo dnf -y install redis

Step 3: Start Redis Service

Once the package is installed, start and enable Redis service to start on boot

sudo systemctl enable --now redis

Step 4: Configure Redis Server on Fedora

We will consider few Redis standard configurations

Enable Listen on all interfaces

By default, Redis service listens on 127.0.0.1. Allow the service to listen on all network interfaces if you need remote clients to connect to it.

Open the file /etc/redis.conf with your favorite text editor

sudo vim /etc/redis.conf

Then change line 66 bind 127.0.0.1 to below:

bind 0.0.0.0

Configure Redis Authentication

Configure Redis Authentication for clients to require AUTH before processing any other commands.

requirepass

Example:

requirepass oobaiY8

Set Persistent Store for Recovery

Set persistence mode by changing the appendonlyvalue to yes

appendonly yes

appendfilename "appendonly.aof"

Restart redis service after making the changes

sudo systemctl restart redis

If you have an active firewalld service, allow port 6379

sudo firewall-cmd --add-port=6379/tcp --permanenent

sudo firewall-cmd --reload

Check redis service status:

$ sudo systemctl status redis

● 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 Mon 2019-05-06 22:10:56 EAT; 12s ago

    Tasks: 4 (limit: 2323)

   Memory: 1.6M

   CGroup: /system.slice/redis.service

           └─4744 /usr/bin/redis-server 127.0.0.1:6379



May 06 22:10:56 localhost.localdomain systemd[1]: Starting Redis persistent key-value database...

May 06 22:10:56 localhost.localdomain systemd[1]: Started Redis persistent key-value database.

Also verify the listen address:

$ sudo ss -tunelp | grep 6379

tcp LISTEN 0 128 *:6379  *:*  users:(("redis-server",pid=28163,fd=4)) uid:995 ino:305

Step 5: Connect to Redis

Confirm that you can connect to redis locally:

$ redis-cli

127.0.0.1:6379>

Test authenticate:

127.0.0.1:6379> AUTH 

OK

You should receive OK in the output. If you input a wrong password, Authentication should fail:

127.0.0.1:6379> AUTH WrongPassword 

(error) ERR invalid password

Check redis information.

127.0.0.1:6379>  INFO

This will output a long list of data. You can limit the output by passing Section as an argument. E.g.

127.0.0.1:6379> INFO Server

Step 6: Perform Redis Benchmarking

Run the benchmark with 20 parallel connections, for a total of 100k requests, against local redis to test its performance.

$ redis-benchmark -h 127.0.0.1 -p 6379 -n 100000 -c 20

................................................

====== LRANGE_600 (first 600 elements) ======

  10000 requests completed in 0.15 seconds

  15 parallel clients

  keep alive: 1



100.00% <= 0 milliseconds

67114.09 requests per second



====== MSET (10 keys) ======
