Running Redis on Ubuntu 20.04

  • Install Redis via apt tool.

    sudo apt update
    sudo apt install redis-server
  • Checking that the Redis service is running:

    sudo systemctl status redis

    If it is running without errors, the output will be like:

    ● redis-server.service - Advanced key-value store
        Loaded: loaded (/lib/systemd/system/redis-server.service; enabled; vendor preset: enable>
        Active: active (running) since Fri 2020-08-07 16:02:26 CST; 6min ago
        Process: 8982 ExecStart=/usr/bin/redis-server /etc/redis/redis.conf (code=exited, status=>
      Main PID: 8983 (redis-server)
          Tasks: 4 (limit: 3713)
        Memory: 2.9M
        CGroup: /system.slice/redis-server.service
                └─8983 /usr/bin/redis-server
  • Connect to the server using redis-cli, the Redis command line interface:

  • Test connection with the ping command:> ping
    PONG> set hello world
    OK> get hello
  • To shutdown the Redis server

    Using redis-cli command to shutdown a Redis server is a relatively elegant way, this will save the data into RDB snapshot before the server shutdown, so you can get data back after the server rebooted.

    redis-cli shutdown [save|nosave]

    You will see the log of Redis outputs:

    $ redis-cli shutdown
    # the Redis server log output
    74902:M 11 Oct 2020 19:10:06.457 # User requested shutdown...
    74902:M 11 Oct 2020 19:10:06.458 * Saving the final RDB snapshot before exiting.
    74902:M 11 Oct 2020 19:10:06.460 * DB saved on disk
    74902:M 11 Oct 2020 19:10:06.460 # Redis is now ready to exit, bye bye...

Start, Stop and disable a system service in Ubuntu system

$ systemctl start redis
$ systemctl stop redis
$ systemctl restart redis

# Enable/disable the redis service at boot
$ systemctl enable redis
$ systemctl disable redis

Running Redis on MacOS

  • Install Redis via brew: brew install redis
  • To start a Redis server:
    • Option 1. Run Redis server as service process:

      brew services start redis
      brew services stop redis
      brew services restart redis
    • Option 2. Run a Redis server and let output shows on terminal:


      To shutdown a Redis server with redis-cli:

      redis-cli shutdown

Deploy Redis in Docker

Pull the Redis image from Docker Hub, start a Redis instance based on Alpine Linux in background, and start listening TCP port 6379:

docker run -d --rm --name redis -p 6379:6379 redis:alpine

Test Redis through telnet command:

telnet 6379

The outputs will be like:

Connected to
Escape character is '^]'.

Note: Exit telnet interface by type in quit command.

And the Redis server is ready to go, test the connection by Redis ping command:


Stop the instance:

docker container stop redis
