      Make a systemD script that is set to start after mongod.
      When the service is started, mongo won't be ready yet to take connections, causing the service to fail if it depends on that.

    Description

      I have the following systemD script for my software:

      [Unit]
      Description=LynxChan
      After=mongod.service
      Wants=mongod.service
       
      [Service]
      ExecStart=/usr/bin/lynxchan
      User=node
      StandardOutput=syslog
      Restart=on-abort
       
      [Install]
      WantedBy=multi-user.target
      

      See "After=mongod.service". Because of that, my software expects mongo to be ready to take connections when it is booted by this init script.
      However, for 3.4, mongo is not ready yet to take connections when my software runs.
      I just tested with 3.2 and everything works as expected, my service is always able to connect to mongo when the system boots.
