Set up Redis in-memory data store¶
Redis is an open source in-memory data structure store and key–value database with optional durability. It’s used as a backend for persistent cache implementation.
1 Install¶
2 Start¶
Since Redis is usually used in our web apps, we want it always running and started automatically after a reboot.
2.1 Start automatically (recommended)¶
2.1.1 If using MacOS with MacPorts¶
Execute on the command line:
sudo port load redis
This will start the server and set it up to start automatically after a reboot.
To stop the server and prevent it from running after a reboot, execute:
sudo port unload redis
2.1.2 If using macOS with Homebrew¶
Execute on the command line:
sudo brew services start redis
This will start the server and set it up to start automatically after a reboot.
To stop the server and prevent it from running after a reboot, execute:
sudo brew services stop redis
2.2 Start manually when needed¶
You can start the server manually by executing on the command line:
redis-server
The server will run in the foreground, and you can stop it when needed
with Control-C.
3 Test¶
To test if the Redis server is running, execute:
redis-cli ping
If correctly started, Redis should respond with PONG.
