# Discourse Migration Guide
|
|
|
|
|
|
|
|
|
|
## Install new server
|
|
|
|
|
|
|
|
|
|
Complete a fresh install of Discourse on the new server, following the official guide, except for the initial database population (rake db:migrate).
|
|
|
|
|
|
|
|
|
|
## Review old server
|
|
|
|
|
|
|
|
|
|
On old server, run `git status` and review changes to the tree. For example:
|
|
|
|
|
|
|
|
|
|
# On branch master
|
|
|
|
|
# Changes not staged for commit:
|
|
|
|
|
# (use "git add <file>..." to update what will be committed)
|
|
|
|
|
# (use "git checkout -- <file>..." to discard changes in working directory)
|
|
|
|
|
#
|
|
|
|
|
# modified: app/assets/javascripts/external/Markdown.Editor.js
|
|
|
|
|
# modified: app/views/layouts/application.html.erb
|
|
|
|
|
# modified: config/application.rb
|
|
|
|
|
#
|
|
|
|
|
# Untracked files:
|
|
|
|
|
# (use "git add <file>..." to include in what will be committed)
|
|
|
|
|
#
|
|
|
|
|
# app/views/layouts/application.html.erb.bitnami
|
|
|
|
|
# config/environments/production.rb
|
|
|
|
|
# log/sidekiq.pid
|
|
|
|
|
# vendor/gems/active_model_serializers/
|
|
|
|
|
# vendor/gems/fast_blank/
|
|
|
|
|
# vendor/gems/message_bus/
|
|
|
|
|
# vendor/gems/redis-rack-cache/
|
|
|
|
|
# vendor/gems/sprockets/
|
|
|
|
|
# vendor/gems/vestal_versions/
|
|
|
|
|
|
|
|
|
|
### Review for changes
|
|
|
|
|
|
|
|
|
|
Review each of the changed files for changes that need to be manually moved over
|
|
|
|
|
|
|
|
|
|
* Ignore all files under vendor/gems
|
|
|
|
|
* Ignore files under log/
|
|
|
|
|
|
|
|
|
|
Check your config/environments/production.rb, config/discourse.pill,
|
|
|
|
|
config/database.yml (as per the upgrade instructions)
|
|
|
|
|
|
|
|
|
|
## Move DB
|
|
|
|
|
|
|
|
|
|
Take DB dump with:
|
|
|
|
|
|
2014-01-30 13:55:43 -05:00
|
|
|
pg_dump --no-owner -U user_name -W database_name > backup_file_name.sql
|
2013-07-21 03:42:07 -04:00
|
|
|
|
|
|
|
|
Copy it over to the new server
|
|
|
|
|
|
|
|
|
|
Run as discourse user:
|
2014-01-30 13:55:43 -05:00
|
|
|
```
|
|
|
|
|
createdb discourse_prod
|
|
|
|
|
psql discourse_prod
|
2014-01-30 14:04:24 -05:00
|
|
|
\i backup_file_name.sql
|
2014-01-30 13:55:43 -05:00
|
|
|
```
|
2013-07-21 03:42:07 -04:00
|
|
|
On oldserver:
|
|
|
|
|
|
2014-01-30 13:55:43 -05:00
|
|
|
`rsync -avz -e ssh public newserver:public`
|
2013-07-21 03:42:07 -04:00
|
|
|
|
2014-01-30 13:55:43 -05:00
|
|
|
On the new server:
|
|
|
|
|
```
|
2013-07-21 03:42:07 -04:00
|
|
|
bundle install --without test --deployment
|
|
|
|
|
RUBY_GC_MALLOC_LIMIT=90000000 RAILS_ENV=production rake db:migrate
|
|
|
|
|
RUBY_GC_MALLOC_LIMIT=90000000 RAILS_ENV=production rake assets:precompile
|
|
|
|
|
RUBY_GC_MALLOC_LIMIT=90000000 RAILS_ENV=production rake posts:rebake
|
2014-01-30 13:55:43 -05:00
|
|
|
```
|
|
|
|
|
If the `rake db:migrate` step fails, you might have to run it twice.
