Dreamhost runs Debian GNU/Linux lenny 5.0.8. You will need to create a new domain or subdomain with Ruby on Rails enabled.
Per Dreamhost policy you are not permitted to run persistent processes on shared hosting plans. This has been verified with Dreamhost Support staff. Persistent processes are only permitted on Dreamhost PS plans.
This means especially network daemons (redis-server) are against the Terms of Service. (DreamHost Policy Bot on 16/09/11)
"Firstly, we reserve the right to kill any user process on a shared server without warning or prior notification at our discretion." We don't just do this capriciously though! We do this if the process is in any way adversely affecting the smooth functioning of your shared server.
- I'm going to ask them if these 3 specific processes (redis-server, resque, websocket_server) can be run (j4v4m4n)
- We can still do it asynchronously, whenever you want to sync, ssh into your shell and run redis-server and resque, login to your pod, do your things, kill those processes and logout from shell. Yeah, not a great way to run, but you get to keep your data.
- There is an option in config/application.yml to run in single process mode, that way we don't have to depend on resque
You need to create a new database for diaspora from dreamhost panel. Bundler
To install Bundler, run the following:
$ gem install bundler
To install Redis follow these steps (you can skip this step if you are going to use single_process_mode):
$ wget http://redis.googlecode.com/files/redis-2.4.5.tar.gz $ tar -zxvf redis-2.4.5.tar.gz $ cd redis-2.4.5 $ cd src; make PREFIX=$HOME/redis $ make PREFIX=$HOME/redis install $ nohup $HOME/redis/bin/redis-server &
Follow remaining steps from main installation article. Just check the notes below for dreamhost specific quirks. Notes
Run these commands from diapsora code directory - $HOME/
To run bundle use ~/.gems/bin/bundle
Note: sqlite3 gem won't work if you don't provide '--without development' option. Also you have to remove lines containing sqlite3 from Gemfile and Gemfile.lock.
$ ~/.gems/bin/bundle install --path vendor/bundle_gems --without development
There is an old version of rack installed by default which conflicts with diapsora
Hack: You have to change rack version to 1.2.1 in Gemfile.lock to make it work, but then it does not work properly.
Change ca_file in config/application.yml (remember dreamhost runs debian)
Invoke all rake commands via budle exec
$ RAILS_ENV=production ~/.gems/bin/bundle exec rake db:migrate
Passenger equivalent to restart is
$ touch tmp/restart.txt
Starting resque (you can skip this step if you are going to use single_process_mode)
$ RAILS_ENV=production QUEUE=* nohup ~/.gems/bin/bundle exec rake resque:work &
Script for starting basic services (script/dreamhost)
Note: See top of this page about restrictions about running background processes. Edit config/application.yml and under production change single_process_mode: true
production: <<: *defaults single_process_mode: true
or if you still want to go with background processes, create script/dreamhost and make it executable (chmod +x script/dreamhost)
nohup ~/.gems/bin/bundle exec ~/redis/bin/redis-server & sleep 10 RAILS_ENV=production QUEUE=* nohup ~/.gems/bin/bundle exec rake resque:work & sleep 10
Note: Currently we get an internal server error if we have websocket_server running, so don't run it. I don't know if it has something to do with older rack version (j4v4m4n)
