Migrating from mybb

Possibly, we add importer features as we have paying business hosted customers to migrate – and we always open source those changes!

Good to hear that! Thanks, Jeff!

Just asking: any paying businesses migrating from MyBB right now? :wink:

Is there a guide for that right now?

It doesn’t look like it. It works like most of them, though, and I recently added code that allows you to configure most everything in environment variables (as well as support permalinks). You’ll need to add the mysql2 gem (and virtually every guide includes how to do that).

How i use import script? Our Mybb forum and Discourse is not on the same server. I think I could create Mybb database backup and run import script?

The usual method is to install a development environment, copy the database to the development server and run the script.

You might use this howto as an example:

Rather than configuring the script as that example suggests, just run it and it’ll tell you what environment variables to set.

I’ve problem in that step (I think its about bundle install):

RAILS_ENV=production ruby script/import_scripts/mybb.rb

After that command here is the error:

are you running the import script as discourse user? If not, you should su - discourse before attempting to run the rails r part.

Hello,

nobody can help me ?

Regards,

Try running the script from /var/www/discourse and not the script directory?

Thank you for your reply

so I have to copy past the mybb.ruby to /var/www/discourse before ?

I copy past mybb.rb in /var/www/discourse

but I have another issue

root@vps-app:/var/www/discourse# RAILS_ENV=production bundle exec ruby mybb.rb
Traceback (most recent call last):
        1: from mybb.rb:1:in `<main>'
mybb.rb:1:in `require': cannot load such file -- mysql2 (LoadError)
root@vps-app:/var/www/discourse#

You’ll need to install the gem. There are some #howto posts for other importers that you should use as a model. You should read those. There are dozens more tiny little things you’ll need to figure out.

If you need so by step help and have a budget my context info is in my profile.

Have no idea how to fix this

Try RAILS_ENV=production rails runner mybb.rb

Thanks for the answer, but i got this now

/usr/local/lib/ruby/gems/2.6.0/gems/activerecord-6.0.1/lib/active_record/connection_adapters/postgresql_adapter.rb:50:in ‘rescue in postgresql_connection': **FATAL: Peer authentication failed for user "discourse" (** **ActiveRecord::NoDatabaseError** **)**

After su into discourse user, i got

Please specify a valid ruby command or the path of a script to run.

Run 'rails runner -h' for help.

undefined local variable or method `mybb' for main:Object

The error is that your rails can’t connect to your postgres database. I would investigate why the discourse user cannot do that.
