Install and configure redis on Ubuntu 16.04
Administrator

install redis follow these steps:

  1. Set up a non-root user with sudo privileges
  2. Install build and test dependencies:
    sudo apt update
    sudo apt full-upgrade
    sudo apt install build-essential tcl
    
  3. Set up redis:
    1. Download latest copy via this link or with this
      curl -O http://download.redis.io/redis-stable.tar.gz
      
    2. Create a temporary folder for it in say your /home/username/redis-stable directory
    3. Move into created folder and extract it
      tar xzvf redis-stable.tar.gz
      
    4. Change into the folder cd redis-stable and build it with
      make
      make test
      sudo make install
      
  4. Configure redis:
    1. Create configuration directory:
      sudo mkdir /etc/redis
      
    2. Move sample redis configuration file:
      sudo cp /home/george/redis-stable/redis.conf /etc/redis
      
    3. Edit the file:
      sudo nano /etc/redis/redis.conf # or with any other text editor
      
    4. Make two changes there:
      supervised no to supervised systemd
      dir to dir /var/lib/redis # for persistent data dump
  5. Set up the systemd unit file:
    sudo nano /etc/systemd/system/redis.service
    

    Add the text:

    [Unit]
    Description=Redis In-Memory Data Store
    After=network.target
    
    [Service]
    User=redis
    Group=redis
    ExecStart=/usr/local/bin/redis-server /etc/redis/redis.conf
    ExecStop=/usr/local/bin/redis-cli shutdown
    Restart=always
    
    [Install]
    WantedBy=multi-user.target
    
  6. Set up redis user, groups and directories:

    create redis user and group with same ID but no home directory:

    sudo adduser --system --group --no-create-home redis   
    sudo mkdir /var/lib/redis   # create directory
    sudo chown redis:redis /var/lib/redis   # make redis own /var/lib/redis
    sudo chmod 770 /var/lib/redis   # adjust permission
    
  7. Test redis:
    1. Start redis service:
      sudo systemctl start redis
      
    2. Check status:
      systemctl status redis
      

      Result of status if started successfully:

      Output

    3. Test instance:
      1. Connect:
        redis-cli
        
      2. Test connectivity at prompt:
        127.0.0.1:6379> ping   # result PONG
        
      3. Check ability to set keys:
        127.0.0.1:6379 set test "It's working!"  # result ok
        
      4. Get the key just set:
        127.0.0.1:6379 get test  # result "It's working!"
        
      5. Exit redis:
        127.0.0.1:6379 exit
