# Alternative Install Options
|
||||
|
||||
Here lie some alternative installation options for Discourse. They're not the
|
||||
recommended way of doing things, hence they're a bit out of the way.
|
||||
|
||||
Oh, and dragons. Lots of dragons.

||||
|
||||
## Web Server Alternative: apache2
|
||||
|
||||
If you instead want to use apache2 to serve the static pages:
|
||||
|
||||
# Run these commands as your normal login (e.g. "michael")
|
||||
# If you don't have apache2 yet
|
||||
sudo apt-get install apache2
|
||||
|
||||
# Edit your site details in a new apache2 config file
|

# Build and install ruby
|
||||
rvm install 2.0.0
|
||||
gem install bundler
|
||||
|
||||
When creating the `discourse` user, add him/her/it to the RVM group:
|
||||
|
||||
# Run these commands as your normal login (e.g. "michael")
|
||||
sudo adduser discourse rvm
|
||||
|
||||
RVM will be located in `/usr/local/rvm` directory instead of `/home/discourse/.rvm`, so update the crontab line respectively.

## What kind of hardware do you have?
|
||||
|
||||
- We *strongly* recommend 2GB of memory minimum if you don't want to deal with swap partitions during the install.
|
||||
- We recommend at least a dual core CPU.
|
||||
- Recommended minimum configuration is:
|
||||
- 2GiB of RAM
|
||||
- 2GiB of swap
|
||||
- 2 processor cores
|
||||
- With 2GB of memory and dual cores, you can run two instances of the thin
|
||||
server (`NUM_WEBS=2`)
|
||||

1 GB of memory and a single core CPU are the minimums for a steady state, running Discourse forum -- but it's simpler to just throw a bit more hardware at the problem if you can, particularly during the install.

# 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/clockworkd.clock.output
|
||||
# log/clockworkd.clock.pid
|
||||
# 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:
|
||||
|
||||
pg_dump --no-owner -U user_name -W database_name
|
||||
|
||||
Copy it over to the new server
|
||||
|
||||
Run as discourse user:
|
||||
|
||||
* createdb discourse_prod
|
||||
* psql discourse_prod
|
||||
* \i discourse_dump_from_old_server.sql
|
||||
|
||||
On oldserver:
|
||||
|
||||
* rsync -avz -e ssh public newserver:public
|
||||
|
||||

Are you having trouble setting up Discourse? Here are some basic things to
|
||||
check before reaching out to the community for help:
|
||||
|
||||
|
||||
1. Are you running Ruby 1.9.3 or later?
|
||||
|
||||
Discourse is designed for Ruby 1.9.3 or later. You can check your version by
|
||||
typing `ruby -v` and checking the response.
|
||||
typing `ruby -v` (as the discourse user) and checking the response for
|
||||
something like:
|
||||
|
||||
`ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-linux]`
|
||||
|
||||
|
||||
2. Are you on Postgres 9.1 or later with HSTORE enabled?
|
||||
1. Are you on Postgres 9.1 or later with HSTORE enabled?
|
||||
|
||||
You can check your postgres version by typing `psql --version`. To see if hstore is

|

|
||||
3. Have you run `bundle install`?
|
||||
1. Have you run `bundle install`?
|
||||
|
||||
We frequently update our dependencies to newer versions. It is a good idea to run
|
||||
`bundle install` every time you check out Discourse, especially if it's been a while.

|

|

4. Did you run `bundle update`?
|
||||
1. Did you run `bundle update`?
|
||||
|
||||
Don't. Running `bundle update` will download gem versions that we haven't tested with.
|
||||
The Gemfile.lock has the gem versions that Discourse currently uses, so `bundle install`
|
||||
will work. If you ran update, then you should uninstall the gems, run
|
||||
`git checkout -- Gemfile.lock` and then run `bundle install`.
|
||||
Don't. Running `bundle update` will download gem versions that we haven't
|
||||
tested with. The Gemfile.lock has the gem versions that Discourse currently
|
||||
uses, so `bundle install` will work. If you ran update, then you should
|
||||
uninstall the gems, run `git checkout -- Gemfile.lock` and then run `bundle
|
||||
install`.

5. Have you migrated your database?

Our schema changes fairly frequently. After checking out the source code, you should

run `rake db:migrate`

1. Do the tests pass?
|

|

6. Have you added the seed data?
|
||||
If you are having other problems, it's useful to know if the test suite
|
||||
passes. You can run it by first using `rake db:test:prepare` and then `rake
|
||||
spec`. If you experience any failures, that's a bad sign! Our master branch
|
||||
should *always* pass every test.
|
||||
|
||||
We depend on some basic seed data being present in the database. You should run
|
||||
`rake db:seed_fu` to keep your database in sync.
|
||||
1. Have you updated host_names in your database.yml?
|
||||
|
||||
If links in emails have localhost in them, then you are still using the
|
||||
default `host_names` value in database.yml. Update it to use your site's host
|
||||
name(s).

Some common situations:
|

|

**Problem:** `ActiveRecord::StatementInvalid (PG::Error: ERROR: column X does not exist`
|
||||
**Solution**: run `db:migrate` task to apply migrations to the database
