An exploration into running multiple Ruby on Rails application each in its own subdirectory on the same virtual host.
There are two very simple RoR applications created by running:
rails new one --skip-yarn --skip-action-mailer --skip-active-record --skip-active-storage --skip-action-cable --skip-sprockets --skip-spring --skip-listen --skip-javascript --skip-bootsnap --skip-system-test
This is basically using all the “skips” documented in rails new -h, so the applications are really bare-bones.
To run the code, change the first two Defines in multi-rails.conf and include it to your Apache HTTP Server configuration. Then, start each RoR application from their own directories with this command:
rails s -b $PWD/tmp/sockets/server.sock
Open virtual host you configured in the browser and you should see you have two running Ruby on Rails applications on one virtual host.
