I have a project to measure temperature and humidity information and then do useful things with it. Right now I need to get the Rails part of my app "stood up" on a server so that it's not constantly in development mode. At the very least I want the web service to be offered on the standard TCP port 80 so I can use HTTP protocol without a port number specifier. Gee, it would be kind of nice too if the service came alive when the server machine boots.
I have been using a procedure at PhusionPassenger.com (this one) but I've tripped over a few things and it didn't work out of the box. If you're looking for a procedure to stand up your Rails app on Passenger you might like to try that one first. It is from Passenger's creators after all. If that doesn't work straight out of the box you might want to try mine.
Disclaimers:
Before we start, we have a laundry list of settings we'll use. You'll likely have your own values for each of these. I'm documenting mine up front so you can tell what I'm doing later. We'll set most of this up as we go along.
I won't cover operating system installation or virtual host installation. It might be useful to you to connect to the machine remotely for this procedure. You can ignore this step if you're just going to use the console of a physical machine or the virtual screen of a virtual machine. If you have not already done so, install SSH.
So that you know the IP address to connect to you can run ifconfig:
Now on your development machine you can use SSH client from a bash prompt or use PuTTY on Windows. See: http://arduinoetcetera.blogspot.com.au/2017/04/the-raspberry-pi-basics.html Use certificate authentication to get rid of the need to log in.
Update the operating system. Run:
Verify server is running
Locate the socket file
BEGIN OPTIONAL
IMPORTANT: Log out and back in.
IMPORTANT: Log out and back in, again!
Install Bundler.
Create web application directory structure
Have a look at your application's code. I have an extra folder level in my code as I'm storing code for the Rails server and embedded devices that will interface with the server all in the same repository. When you clone into the 'code' folder you should see your Rails project there.
ASIDE: I get this warning about the PATH but when I check it using printenv it's right. Whatever. The second time I run the command I don't get a warning.
Drop back from the application user account to the administrator account.
Edit the rc.local file to make the Rails secret_key_base and database password available to the root user.
Add these two lines before 'exit 0'.
NOTE: If you're not familiar with nano you'll need to use your cursor keys to move the cursor down a row at a time until you get to just above 'exit 0'. You should then be able to copy the two lines below and paste them into the file.
Close the file saving changes (Ctrl-x then Y then Enter).
In your terminal window, go back up to the line where we previously performed a 'bundle exec rake secret'. Copy the entire text that was produced. Go back into the rc.local file using 'sudo nano /etc/rc.local', remove 'HexadecimalTextFromBundleExecRakeSecret' and paste instead what you just copied. While in the file, replace TheActualPasswordHere with the password for the application's DATABASE user account. If you have changed the names of the environment variables alter them too (See settings above near the top of this document). The edited file will look like this:
Exit saving changes again.
Print the rc.local file to the terminal.
Now copy and past the two export commands into the current terminal session.
NOTE: I found that if the Secret Key Base wraps around in the terminal display it won't paste in as a single command. You may need to widen your terminal and print the rc.local file out again.
You can verify these environment variables are now available to the current user.
Having checked that, we can now run the database migration.
Add the following two lines between the two export commands and the 'exit 0' at the end of the file. Of course you should modify them to suit your paths.
The completed rc.local file looks like this
Make the rc.local file executable.
Reboot the Passenger server.
Verify Passenger auto-starts. After the reboot, log back in to an SSH session or console. Check the passenger processes are running
Check your home page or an API view loads.
NOTE: To ensure rvmSecretKeyBase is not truncated, the terminal needs to be wide enough so that the rvmSecretKeyBase line is not wrapped.
That is all.

If you're looking for a procedure to stand up your Rails app on Passenger you might like to try that one first. It is from Passenger's creators after all. If that doesn't work straight out of the box you might want to try mine.
Disclaimers:
- All due respect to Phusion. This is not an attempt to republish their work. My own attempts to make their procedure work resulted in a complete re-write and so I thought it was deserving of a post.
- I've chosen to host on an old netbook which is not exposed to the Internet. I don't recommend you use this procedure and then connect the server to the Internet without first performing some rigorous system hardening.
- I've used a virtual machine (Parallels 11 on macOS Sierra) for the development of this procedure. This should not affect the outcome. Any machine physical or virtual should do as long as you can install Ubuntu 16.04.2 LTE Desktop or Server onto it.
Before we start, we have a laundry list of settings we'll use. You'll likely have your own values for each of these. I'm documenting mine up front so you can tell what I'm doing later. We'll set most of this up as we go along.

Code
We need to make changes to the code base to prepare for deployment on Passenger in a stand-alone configuration. You might use sqlite or MySQL in development but we'll set up on MySQL for production. Best security practice has us using environment variables to store the most critical security variables; the "Secret Key Base" that secures sessions with the server and the password used to access the database.Gemfile
We modify the gemfile so that only Passenger is used to serve the app. Comment out other server options if they are present. Ensure "passenger" is present and not commented out. You will also need to include the mysql2 gem. This always gets me into trouble. The suffix I use currently is one I've found works for me at the moment. gem "passenger"
gem 'mysql2', '>= 0.3.18', '< 0.5'
# gem "unicorn"
# gem "thin"
# gem "puma"
Passenger config file
This file would not have been created by Rails. You need to create a new text file in the root of your Rails application named Passenger.json. Paste in the content below and alter the "user" value to suit your own setting. {
// Run the app in a production environment. The default value is "development".
"environment": "production",
// Run Passenger on port 80, the standard HTTP port.
"port": 80,
// Tell Passenger to daemonize into the background.
"daemonize": true,
// Tell Passenger to run the app as the given user. Only has effect
// if Passenger was started with root privileges.
"user": "conditionsuser"
}
Secrets
Ensure the secret_key_base definition is part of the production section of config/secrets.yml. Name the variable anything you like but keep the "rvm" prefix. This is required when we later use the "rvmsudo" command.
production:
secret_key_base: <%= ENV["rvmSecretKeyBase"] %>
Database
In config/database.yml ensure the production database configuration accesses an environment variable for the database password. Also, ensure the database name, database user name and socket have the correct values as seen above. Again, the environment variable can be named as you like but should start with "rvm".
production:
<<: *default
database: Conditions
username: conditionsUser
password: <%= ENV['rvmConditionsDatabaseUserPassword'] %>
socket: /run/mysqld/mysqld.sock
Repository Setup
To move the application's code onto the server we will pull from a code repository using git (Github, BitBucket, etc.) If your development code is not already in a git repository now's the time to set that up.
Push code
After making all of the above changes to the development code base, 'bundle install', commit and push your code.

Installing RVM to /usr/local/rvm/
Installation of RVM in /usr/local/rvm/ is almost complete:
* First you need to add all users that will be using rvm to 'rvm' group,
and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.
* To start using RVM you need to run `source /etc/profile.d/rvm.sh`
in all your open shell windows, in rare cases you need to reopen all shell windows.
# prawnhead,
#
# Thank you for using RVM!
# We sincerely hope that RVM helps to make your life easier and more enjoyable!!!

conditionsuser@ubuntu:/var/www/Conditions/code/ConditionsServer$ Set Default Ruby Version
As we have changed user context, we need to again set the default Ruby version for RVM to use.ASIDE: I get this warning about the PATH but when I check it using printenv it's right. Whatever. The second time I run the command I don't get a warning.
conditionsuser@ubuntu:/var/www/Conditions/code/ConditionsServer$ rvm use ruby-2.4.0
Warning! PATH is not properly set up, '/usr/local/rvm/gems/ruby-2.4.0/bin' is not at first place.
Usually this is caused by shell initialization files. Search for 'PATH=...' entries.
You can also re-add RVM to your profile by running: 'rvm get stable --auto-dotfiles'.
To fix it temporarily in this shell session run: 'rvm use ruby-2.4.0'.
To ignore this error add rvm_silence_path_mismatch_check_flag=1 to your ~/.rvmrc file.
Using /usr/local/rvm/gems/ruby-2.4.0
conditionsuser@ubuntu:/var/www/Conditions/code/ConditionsServer$ rvm use ruby-2.4.0

conditionsuser@ubuntu:/var/www/Conditions/code/ConditionsServer$ Generate Secret
We need to generate a high entropy hexadecimal string for Rails to use in securing sessions. Run the following command, we'll come back in a minute to copy-paste this value into a file we'll open. conditionsuser@ubuntu:/var/www/Conditions/code/ConditionsServer$ bundle exec rake secret
b52ca24cc75b75b7bbc707fa311f5978b225593f5d16d33cf0e5292b89f7f3159cac253ee81dccb4efb6efc1dd1e1949b0613b44529b7b5fd170c6d7244e93f7
conditionsuser@ubuntu:/var/www/Conditions/code/ConditionsServer$
Edit rc.local
Commands in rc.local are executed under the root user when the system starts. When we define our environment variables here they are available when the system boots so it can start our application automatically.Drop back from the application user account to the administrator account.
conditionsuser@ubuntu:/var/www/Conditions/code/ConditionsServer$ exit
logout
prawnhead@ubuntu:/var/www/Conditions/code/ConditionsServer$
Edit the rc.local file to make the Rails secret_key_base and database password available to the root user.
prawnhead@ubuntu:/var/www/Conditions/code/ConditionsServer$ sudo nano /etc/rc.local
[sudo] password for prawnhead:
Add these two lines before 'exit 0'.
NOTE: If you're not familiar with nano you'll need to use your cursor keys to move the cursor down a row at a time until you get to just above 'exit 0'. You should then be able to copy the two lines below and paste them into the file.
export rvmSecretKeyBase=HexadecimalTextFromBundleExecRakeSecret
export rvmConditionsDatabaseUserPassword=TheActualPasswordHere
Close the file saving changes (Ctrl-x then Y then Enter).
In your terminal window, go back up to the line where we previously performed a 'bundle exec rake secret'. Copy the entire text that was produced. Go back into the rc.local file using 'sudo nano /etc/rc.local', remove 'HexadecimalTextFromBundleExecRakeSecret' and paste instead what you just copied. While in the file, replace TheActualPasswordHere with the password for the application's DATABASE user account. If you have changed the names of the environment variables alter them too (See settings above near the top of this document). The edited file will look like this:
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
export rvmSecretKeyBase=b52ca24cc75b75b7bbc707fa311f5978b225593f5d16d33cf0e5292b89f7f3159cac253ee81dccb4efb6efc1dd1e1949b0613b44529b7b
5fd170c6d7244e93f7
export rvmConditionsDatabaseUserPassword=6Thur5day
exit 0
Exit saving changes again.
Perform Database Migration
We need to run the database migrations. Until now we haven't had an environment variable to hold the database password. However, the one we've created is only accessible to the root account as the system boots. So we can use those environment variables now to do the database migrations, we just need to execute them in the context of the current user's session.Print the rc.local file to the terminal.
prawnhead@ubuntu:/var/www/Conditions/code/ConditionsServer$ more /etc/rc.local
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
export rvmSecretKeyBase=b52ca24cc75b75b7bbc707fa311f5978b225593f5d16d33cf0e5292b89f7f3159cac253ee81dccb4efb6efc1dd1e1949b0613b44529b7b
5fd170c6d7244e93f7
export rvmConditionsDatabaseUserPassword=6Thur5day
exit 0
prawnhead@ubuntu:/var/www/Conditions/code/ConditionsServer$
Now copy and past the two export commands into the current terminal session.
NOTE: I found that if the Secret Key Base wraps around in the terminal display it won't paste in as a single command. You may need to widen your terminal and print the rc.local file out again.
prawnhead@ubuntu:/var/www/Conditions/code/ConditionsServer$ export rvmSecretKeyBase=b52ca24cc75b75b7bbc707fa311f5978b225593f5d16d33cf0e5292b89f7f3159cac253ee81dccb4efb6efc1dd1e1949b0613b44529b7b5fd170c6d7244e93f7
prawnhead@ubuntu:/var/www/Conditions/code/ConditionsServer$ export rvmConditionsDatabaseUserPassword=6Thur5day
prawnhead@ubuntu:/var/www/Conditions/code/ConditionsServer$
You can verify these environment variables are now available to the current user.

You should now be able to hit your app using a web browser and just the IP address of the Passenger server (eg. http://10.211.55.15). If, like me, your app is a REST API, you will have to hit one of the views (eg. http://10.211.55.15/stations.json) prawnhead@ubuntu:/var/www/Conditions/code/ConditionsServer$ curl http://10.211.55.15/stations.json

prawnhead@ubuntu:/var/www/Conditions/code/ConditionsServer$ Application Auto-Start
To make the application start automatically when the system boots we only need to make two changes to the rc.local file.Locate your rvm-exec file and copy the path.
prawnhead@ubuntu:/var/www/Conditions/code/ConditionsServer$ which rvm-exec
/usr/local/rvm/bin/rvm-exec
prawnhead@ubuntu:/var/www/Conditions/code/ConditionsServer$ Edit rc.local
prawnhead@ubuntu:/var/www/Conditions/code/ConditionsServer$ sudo nano /etc/rc.local
[sudo] password for prawnhead:
Add the following two lines between the two export commands and the 'exit 0' at the end of the file. Of course you should modify them to suit your paths.
cd /var/www/Conditions/code/ConditionsServer
/usr/local/rvm/bin/rvm-exec ruby-2.4.0 bundle exec passenger start
The completed rc.local file looks like this
prawnhead@ubuntu:/var/www/Conditions/code/ConditionsServer$ more /etc/rc.local
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other

Set the Ruby version
conditionsuser@ubuntu:/var/www/Conditions/code$ rvm use ruby-2.4.0
Warning! PATH is not properly set up, '/usr/local/rvm/gems/ruby-2.4.0/bin' is not at first place.
Usually this is caused by shell initialization files. Search for 'PATH=...' entries.
You can also re-add RVM to your profile by running: 'rvm get stable --auto-dotfiles'.
To fix it temporarily in this shell session run: 'rvm use ruby-2.4.0'.
To ignore this error add rvm_silence_path_mismatch_check_flag=1 to your ~/.rvmrc file.
