Install Ruby on Rails and Redmine on DS210+

I mentioned it in my manual for (trying) installing Redmine on a DS106j, the 32MB are to few.

As we got a new DS210+ with 512MB RAM and a 1 GHz CPU there was a new chance to get Redmine up and running - and it works!

pre-requirements

install Ruby on Rails

As you have ipkg up and running, you can simply use the following command to install ruby: 

ipkg install rubygems

Additionally (maybe it is not necessary) install zlib: 

ipkg install zlib

Now install Rails in Version 2.3.5 to be fit most Redmine pre-requirements (this step will take ca. 30 Minutes even on the shiny new DS210+ so imagine that on the DS106j): 

gem install rails -v 2.3.5

install Redmine

Use phpMyAdmin to create a database redmine and optionally a MySQL-user redmine with the rights to access it.

install ruby-mysql 

wget http://github.com/downloads/tmtm/ruby-mysql/ruby-mysql-2.9.3-beta.tar.gz
tar -xzvf ruby-mysql-2.9.3-beta.tar.gz
cd ruby-mysql-2.9.2-beta 
ruby setup.rb

create a folder in /volume1 for the redmine service: 

cd /volume1
mkdir rubyapps
cd rubyapps

download redmin (We have used the 0.9.5 because we had some strange errors with the newest 1.0.1 redmine): 

wget http://rubyforge.org/frs/download.php/71421/redmine-0.9.5.tar.gz

extract it: 

tar -xzvf redmine-0.9.5.tar.gz

create a symbolic link to the folder (for easier access later): 

ln -s redmine-0.9.5 redmine

change the rights of the folder to the user redmine: 

chown redmine:1000 redmine-0.9.5 -R

configure Redmine

login as user redmine: 

su redmine

change to folder config in redmine and create database.yml 

cd /volume1/rubyapps/redmine/config
cp database.yml.example database.yml

edit the database.yml 

nano database.yml

change: 

production:
adapter: mysql
database: redmine <= created in MySQL
host: localhost
username: redmine <= created in MySQL
password: my_password <= set for the user redmine n MySQL


in folder config run following command: 

RAILS_ENV=production rake initializers/session_store.rb

Job done!

start Redmine Service

change to root folder of redmine installation: 

cd /volume1/rubyapps/redmine

And start the service: 

ruby script/server webrick -e production

You can now use your browser and surf to: 

http://synolgyIP:3000

start stop script for automatically start service on boot

create the file S97redmine.sh in /usr/syno/etc.defaults/rc.d/ and make it runnable.

Following content (correct the paths!): 

#!/bin/sh
case "$1" in
     start)
     /opt/bin/ruby /volume1/rubyapps/redmine/script/server webrick -d -e production 
     ;;
     stop)
     killall ruby
     ;;
     restart)
     $0 stop
     sleep 1
     $0 start
     ;;
     *)
     echo “usage: $0 { start | stop | restart}” >&2
     exit 1
     ;;
     esac


Make it runnable: 

chmod 755 S97redmine.sh

And here is the annoying point

as you have created the system user redmine and changed the folder rights to this user, you may wish to start the deamon as this user, to avoid root to be the files owner. I first thought of using su, so changing the line /opt/bin/ruby to: 

/bin/su redmine -c "/opt/bin/ruby /volume1/rubyapps/redmine/script/server webrick -d -e production"

This doesn't work. So I tried to use sudo - installed it with ipkg install sudo and changed the line to: 

/opt/bin/sudo -u redmine /opt/bin/ruby /volume1/rubyapps/redmine/script/server webrick -d -e production

This also doesn't work.

My assumption is that the -d to start it as a deamon, prevents the service to be run as a different user than root.

So i tried to run it without the -d and fork it away with the & 

/opt/bin/sudo -u redmine /opt/bin/ruby /volume1/rubyapps/redmine/script/server webrick -e production &

Also doesn't work.
