Install and configure redis on Ubuntu 16.04

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
      ● redis.service - Redis Server
       Loaded: loaded (/etc/systemd/system/redis.service; enabled; vendor preset: enabled)

                └─3124 /usr/local/bin/redis-server 127.0.0.1:6379
      

   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
         

      6. Restart redis and then re-run steps 1, 4, and 5:

         sudo systemctl restart redis
         

8. Enable redis to start at boot:

   sudo systemctl enable redis
