Rails 7 support?

lunarcreative

Can I use ruby 3 and rails 7 on opalstack? I have an app written already on this version and I need to host it.
I've seen that there is support for ruby 2.6.5 by default.

Ok, I've found this: https://community.opalstack.com/d/273-howto-run-old-or-new-rails-apps-with-rvm-nginx-and-passenger
I will try to follow and will update here if all good

lunarcreative We're working on our Rails 7 installer at this time and should have it ready soon.

In the meantime the rvm solution is a good workaround.

lunarcreative

Yes, I need to run it today😃 I will gladly test rails7 installer when its ready.
Are version of the gem in the instruction accurate for rails 7 / ruby 3.0.0 ? (rack-cache / passenger/ nginx) or should i opt for some newer versions of them?

sean

lunarcreative the versions used in the post are just an example. If you're trying to run the latest of everything then feel try to give it a try.

So I think I'm almost there, but unfortunately not an nginx expert. I got following error:

2022/01/09 15:53:36 [error] 109869#0: *1 directory index of "/home/ebetecos/apps/harda_new/myproject/public/" is forbidden, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "hardanew.lunarcreative.opalstacked.com"
2022/01/09 15:53:37 [error] 109869#0: *2 directory index of "/home/ebetecos/apps/harda_new/myproject/public/" is forbidden, client: 127.0.0.1, server: localhost, request: "GET / HTTP/1.1", host: "hardanew.lunarcreative.opalstacked.com"

And public dir is:
drwxrwxr-x

Maybe I have some simple config issue, if not I will try to dig this more.

Ok, quick update, I've added to nginx conf server section:
passenger_enabled on;
And now i have issues with sqlite, that I will try to fix🙂

@sean
I've managed to run rails, but have issue with sqlite3 versions:
Your version of SQLite (3.7.17) is too old. Active Record supports SQLite >= 3.8.
Is it possible to upgrade it on my user? Or should i go for postgres or mysql? Its simple project and i don't have strong db preference tbh

sean

lunarcreative There's a newer sqlite available on the server but you need to configure your app's environment to use it.

For Nginx + Passenger you'll need to change this line in nginx.conf...

env               LD_LIBRARY_PATH=/opt/lib;

... to this:

env               LD_LIBRARY_PATH=/usr/sqlite330/lib:/opt/lib;

Instructions for using the different types of DB services with your Rails app are available at: Using Databases with Ruby on Rails

Ok, App is up and runinng. I will wrap app all config nginx and gem version I've used and will post here for others
