How to Install Redis on MacOS

Redis is an in-memory data structure store used as a database, cache, and message broker. It supports various data structures, including strings, hashes, lists, sets, sorted sets with range queries, bitmaps, HyperLogLogs, geospatial indexes, and streams.

Installing Redis on macOS can seem difficult if you are not familiar with the command line but this post will cover you through the process step-by-step to ensure a smooth setup.

Prerequisites

Before you begin to install Redis MacOS, ensure that you have the following prerequisites:

1. A MacOS system with administrative access.
2. Basic knowledge of terminal commands.
3. Homebrew installed on your system.

Installing Homebrew

Homebrew is a package manager for macOS that simplifies the installation of software. If you haven’t installed Homebrew yet, you can do so by executing the following command in your terminal:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

After running this command, follow the instructions to complete the Homebrew installation. You can verify that Homebrew is installed by typing:

brew --version

This should display the version of Homebrew installed on your system.

Installing Redis

With Homebrew installed, you can now proceed to Redis install MacOS. Run the following command in your terminal:

brew install redis

This command will download and install Redis and its dependencies. The installation process might take a few minutes.

Configure Redis

After MacOS install Redis, you need to configure it to start automatically whenever your system boots up. Run the following commands in your terminal:

brew services start redis

This command will set up Redis as a background service. You can check the status of Redis with:

brew services list

To stop Redis from running as a service, you can use:

brew services stop redis

Verify Redis

Once Redis is installed and configured verify that it is working correctly. You can do this by starting the Redis server and the Redis command-line interface.

First, start the Redis server:

redis-server

Open a new terminal window or tab, and in the new terminal, start the Redis CLI:

redis-cli

In the Redis CLI, you can now run a few commands to test the installation. For example:

set test "Hello, Redis!"
get test

You should see the output:

This indicates that Redis is working correctly on your system. Implement Redis as cache to increase your website speed faster.

Redis Configuration File

The Redis configuration file is located at /usr/local/etc/redis.conf. This file contains various settings that control the behavior of the Redis server. You can edit this file to change settings such as the default port, logging behavior, and more.

To edit the Redis configuration file, you can use a text editor like nano or vim:

nano /usr/local/etc/redis.conf

Make any necessary changes such as port number changing then save the file.

Advanced Configuration

For more advanced configuration, you might want to look into the following settings:

• By default, Redis saves data to disk periodically. You can configure how often it saves data by modifying the save directive in the configuration file. For example, save 900 1 means Redis will save data every 900 seconds if at least 1 key has changed.
• You can secure your Redis instance by setting a password. Add the requirepass YOUR_PASSWORD line to your configuration file.
• Redis binds to all interfaces by default. To restrict access to specific interfaces, modify the bind directive in the configuration file. For example, bind 127.0.0.1 will restrict access to localhost only.

Troubleshooting

If you encounter any issues during the installation or use of Redis, here are some common troubleshooting steps:

• Ensure that no other application is using the default Redis port 6379. You can change the port in the configuration file if needed.
• Make sure the Redis server is running and that your client is connecting to the correct port and IP address.
• you have the necessary permissions to install and run Redis.

Conclusion

Installing and configuring Redis on macOS is a straightforward process with Homebrew. With Redis up and running, you can use its powerful data structures and high performance for various applications, from caching to real-time analytics. By following the steps in this guide, you should have a fully functional Redis setup ready to use.
