Tapestry

h1. Installing the Tapestry application

The recommended ruby stack for Tapestry is Ruby Enterprise Edition (1.8.7), installed via rvm.

Install rvm:

  curl -L https://get.rvm.io | sudo bash -s stable

Install ree 1.8.7

  sudo rvm install ree

Install rails.

 sudo gem install rails

sudo gem install passenger

sudo /usr/local/bin/passenger-install-apache2-module

Add stuff (as provided by passenger-install) to your conf.d/passenger.conf

<pre>

LoadModule passenger_module /usr/local/lib/ruby/gems/1.8/gems/passenger-3.0.9/ext/apache2/mod_passenger.so

PassengerRoot /usr/local/lib/ruby/gems/1.8/gems/passenger-3.0.9

PassengerRuby /usr/local/bin/ruby

RackEnv "development"

</pre>

Install some prerequisites for gems.

 sudo apt-get install libxslt-dev libxml2-dev

Check out git repo from git@git.clinicalfuture.com:tapestry.git to somewhere -- say, /var/www/tapestry.example.org

Then execute:

 sudo bundle install

Point a virtualhost to the @public@ dir in your git repo

<pre>

<VirtualHost *:80>

   ServerName tapestry.example.org

   DocumentRoot /var/www/tapestry.example.org/public

   <Directory /var/www/tapestry.example.org/public>

         AllowOverride all

         Options -MultiViews

   </Directory>

   Alias /warehouse /warehouse

   <Directory /warehouse>

         Options None

         AllowOverride None

         Order allow,deny

         allow from all

   </Directory>

</VirtualHost>

</pre>

Copy @config/database.example@ to @config/database.yml@ and edit to suit. Make sure to select mysql as the database server.  Generate a password using @pwgen 12 1@ or @head -c12345 /dev/urandom|md5sum|head -c12;echo@.  For example:

 development:

  adapter: mysql

  server: localhost

  database: mypg

  username: mypg

  password: c16fbe415d29

  timeout: 5000

Copy @config/environments/development.rb.sample@ to @config/environments/development.rb@ and edit to suit.  In particular the ROOT_URL (you may skip the "http://" prefix):

 ROOT_URL = 'your.vhost.name'

Set up the database:

 rake db:setup

rake db:schema:load

Set up data directory (replace USERNAME with the user who owns the GIT directory this code is in, and ROOT_URL matching the one above):

 sudo mkdir -p /data/ROOT_URL

sudo chown -R USERNAME:USERNAME /data/ROOT_URL

After you do a git pull, you'll probably want to do

  rake db:migrate

to bring your database up to the latest release.

If the Gemfile has changed, you will also have to run

  sudo bundle install

Set up cron jobs -- for example, @/etc/cron.d/tapestry-get-blog-feed@

 PATH=/usr/local/bin:/usr/bin:/bin

0 * * * * www-data cd /var/www/my-dev.personalgenomes.org/current/script && ./get-blog-feed.rb development http://blog.personalgenomes.org/feed/

To enable large uploads with warehouse storage:

* @sudo apt-get install runit fuse-utils@

* @sudo mkdir -p /etc/service/whmount/log/main@

* Set up supervised whmount service:

<pre>

sudo tee /etc/service/whmount/run <<EOF >/dev/null

#!/bin/sh

modprobe fuse

mkdir -p /warehouse

chown www-data:www-data /warehouse

sudo -u www-data fusermount -u /warehouse

exec sudo -u www-data whmount --no-detach / /warehouse

EOF

sudo tee /etc/service/whmount/log/run <<EOF >/dev/null

#!/bin/sh

exec svlogd -tt main

EOF

</pre>

* Make sure config/environments/development.rb matches your Apache and filesystem mount points:

<pre>

  WAREHOUSE_WEB_ROOT = "/warehouse" # Apache alias pointing to whmount target

  WAREHOUSE_FS_ROOT = "/warehouse" # whmount target

</pre>
