I’m trying to migrate a MyBB instance and haven’t found a walk-through, so hopefully this can become one. I’m also new to Rails and Docker. So far I’ve installed the Discourse Docker image, launched a local MySQL server and populated it with the data from MyBB. The migration script only says it should be called like this: RAILS_ENV=production bundle exec ruby script/import_scripts/mybb.rb That assumes you have cloned the discourse repo itself (not the Docker). So you have to first mkdir /var/discourse.src git clone https://github.com/discourse/discourse.git /var/discourse.src cd /var/discourse.src You also need to run apt-get install bundler After that, I’m out of my depth. bundle install says “You are running an old version of bundler, please update by running: gem install bundler” but after I run gem install bundler (which gets bundler-1.8.2) and re-run bundle install, I get the same warning. Anyway, the blocker is Gem::InstallError: better_errors requires Ruby version >= 2.0.0. Do I just go ahead and install Ruby 2.1.5? How do I do that inside the Docker container? Is Discourse compatible with Ruby 2? If so, should the Docker image be updated? I gave a try to installing Ruby 2.1.5, but I still get the error about Ruby >= 2.0.0. being required: root@...:/var/discosrc# RAILS_ENV=production bundle exec ruby script/import_scripts/mybb.rb Could not find rake-10.4.2 in any of the sources Run `bundle install` to install missing gems. root@...:/var/discosrc# bundle install Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break this application for all non-root users on this machine.

@elberet, thanks for your help so far. I went for the second option - connecting from the Discourse machine to the MySQL server of the running forum (set to maintenance mode) after enabling port 3306 in the firewall and setting bind-address = 0.0.0.0 in /etc/mysql/my.cnf followed by a sudo service mysql restart. Here’s what I’ve done based on your advice: cd /var/discourse ./launcher enter app apt-get update apt-get install libmysqlclient-dev mc -y gem install mysql2 # mysql2-0.3.18 got installed su - discourse cd /var/www/discourse/script/import_scripts bundle install mcedit mybb.rb # make edits to the MySQL connection details RAILS_ENV=production ruby mybb.rb # no idea what "bundle exec" does To setup redirects from the old forum thread URLs to Discourse topics, see my other post: https://meta.discourse.org/t/redirecting-old-forum-urls-to-new-discourse-urls/20930/21?u=dandv

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 ` ' 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.

Guys, Anyone success migrate from mybb to discourse? i got this discourse@hn-app:/var/www/discourse/script/import_scripts$ RAILS_ENV=production ruby mybb.rb **Traceback** (most recent call last): 23: from mybb.rb:4:in ` ' 22: from /usr/local/lib/ruby/site_ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require' 21: from /usr/local/lib/ruby/site_ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require' 20: from /var/www/discourse/script/import_scripts/base.rb:16:in ` ' 19: from /var/www/discourse/script/import_scripts/base.rb:16:in `require_relative' 18: from /var/www/discourse/config/environment.rb:4:in ` ' 17: from /usr/local/lib/ruby/site_ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require' 16: from /usr/local/lib/ruby/site_ruby/2.6.0/rubygems/core_ext/kernel_require.rb:54:in `require' 15: from /var/www/discourse/config/application.rb:58:in ` ' 14: from /var/www/discourse/config/application.rb:59:in ` ' 13: from /var/www/discourse/config/application.rb:75:in ` ' 12: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.1/lib/active_support/dependencies.rb:280:in `require_dependency' 11: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.1/lib/active_support/dependencies.rb:368:in `depend_on' 10: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.1/lib/active_support/dependencies.rb:390:in `require_or_load' 9: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.1/lib/active_support/dependencies.rb:40:in `load_interlock' 8: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.1/lib/active_support/dependencies/interlock.rb:13:in `loading' 7: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.1/lib/active_support/concurrency/share_lock.rb:151:in `exclusive' 6: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.1/lib/active_support/dependencies/interlock.rb:14:in `block in loading' 5: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.1/lib/active_support/dependencies.rb:40:in `block in load_interlock' 4: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.1/lib/active_support/dependencies.rb:407:in `block in require_or_load' 3: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.1/lib/active_support/dependencies.rb:510:in `load_file' 2: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.1/lib/active_support/dependencies.rb:702:in `new_constants_in' 1: from /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.1/lib/active_support/dependencies.rb:511:in `block in load_file' /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activesupport-6.0.1/lib/active_support/dependencies.rb:511:in `load': **No such file to load -- lib/discourse.rb (** **LoadError** **)** Have no idea how to fix this
