I'm following this tutorial to set up a Rails server, but when I try to start the unicorn application server I encounter this error:
$ sudo service unicorn_appname start
Job for unicorn_appname.service failed because the control process exited with error code. See "systemctl status unicorn_appname.service" and "journalctl -xe" for details.
More details:
$ systemctl status unicorn_appname.service
● unicorn_appname.service - LSB: starts the unicorn app server

I tried typing these error messages on google but none gave any helpful results, and I'm kind of stuck now because I'm a total beginner with Rails and setting up web servers in general. Any tips?
As it was pointed out in the comments the problem was in this line:
/etc/init.d/unicorn_appname: 30: cd: can't cd to /home/deploy/appname
In the tutorial there is a file called /etc/init.d/unicorn_appname and I forgot to replace the user of the author (deploy) by mine. Later I encountered another problem. Same immediate output, different answer by systemctl but it all came down to this line:
bundler: command not found: unicorn
I solved it by installing the dependencies of my project globally:
sudo bundle install
I don't know if this is the best option and I still don't know if the overall system will work as a whole because I haven't configued nginx yet but I had no error messages from the command sudo service unicorn_appname start. Other answers are welcomed.
