Answer 1

try to add to /etc/rc.local this:

ruby /path/to/your/app/script/rails s -P /path/to/your/app/tmp/pids/server.pid -c /path/to/your/app/config.ru -d

But better to use passenger gem here with Nginx or Apache

It is easy to setup and easy to use

I've was getting the same error with RVM, ruby, and rails. My directory is /home/user/rails-project/ . Putting this in .bashrc allows me to use the "rvm" command:

source ~/.rvm/scripts/rvm

server$:which rails :

/home/user/.rvm/gems/ruby-2.2.1/bin/rails

The above shows the current rails bin.

So, the final command in rc.local is:

su user-c  "source ~/.rvm/scripts/rvm ; cd /home/user/rails-project/ ; /home/user/.rvm/gems/ruby-2.2.1/bin/rails s -d -e production"

You can use this code in rc.local to debug:

exec 2> /tmp/rc.local.log      # send stderr from rc.local to a log file
exec 1>&2                      # send stdout to the same log file
set -x                         # tell sh to display commands before execution

Use sudo service rc.local start for testing without a reboot.

I was able to accomplish this in the following way:

create a script "rails.run" with the following line to start the ruby on rails with the desired user and parameters:

sudo -H -u <username> bash -c '/home/username/.rbenv/versions/2.2.3/bin/ruby bin/rails server --port=3000 --binding=ip_address -d'

Then add the script in the rc.local file with a simple line such as:

/home/username/rails.run
