The whole story is based on Ubuntu 18.04 LTS, for different system you need to adapt accordingly

  1. Download binary from - in my case it is mercure_X.X.X_Linux_x86_64.tar.gz
  2. move it to /usr/sbin
  3. generate jwt keys
    • ssh-keygen -t rsa -b 4096 -m PEM -f jwt.key
    • openssl rsa -in jwt.key -pubout -outform PEM -out jwt.key.pub
    • move them to /etc/mercure
  4. create mercure.yaml config file in /etc/mercure
    • with just one entry addr: 127.0.0.1:3333
  5. first run try:
    • JWT_KEY=`cat jwt.key.pub` /usr/sbin/mercure - should start the server with message similar to this INFO[0000] Mercure started addr="127.0.0.1:3333" protocol=http
  6. create /etc/systemd/system/mercure.service with below content 
         [Unit]
     Description=Mercure.Rocks service
     After=network.target
     StartLimitBurst=5
     StartLimitIntervalSec=33

     [Service]
     Type=simple
     WorkingDirectory=/tmp
     Environment=JWT_KEY=`cat jwt.key.pub`
     ExecStart=/usr/sbin/mercure
     StandardOutput=file:/var/log/mercure.log
     StandardError=file:/var/log/mercure.log
     Restart=always
     RestartSec=5

     [Install]
     WantedBy=multi-user.target
  7. run sudo systemctl daemon-reload
  8. run sudo systemctl enable mercure.service
  9. run sudo systemctl start mercure.service
  10. and to see if it is working run sudo systemctl status mercure
