Server on Ubuntu x86
Moved server-setup.sh script down into directory with Sinatra server code.
I used VMWare workstation (easy install) to create a VM based on the ubuntu-12.04.1-desktop-amd64 ISO image.
In the VM settings, check the Network Adapter connection type. This may have defaulted to NAT. Set it to Bridged (but don't need to check the Replicate physical network connection state option). This makes the VM-based server visible to client systems on the LAN.
After the initial OS installation, do the following in a terminal:
sudo apt-get update
sudo apt-get install git
Also need to increase open files limit (ulimit -n) for Neo4j. Edit /etc/security/limits.conf and add lines like this, replacing 'userid' with the userid you will use to run the Napkin server:
userid hard nofile 40000
userid soft nofile 40000
Reboot the system after editing the limits.conf file for the changes to take effect.
Get the Server JRE download from the Oracle Java site.
cd ~
mkdir java
cd java
tar xvf server-jre-7u45-linux-x64.tar.gz
cd ~
mkdir jruby
cd jruby
wget -O jruby-bin-1.7.9.tar.gz 'http://jruby.org.s3.amazonaws.com/downloads/1.7.9/jruby-bin-1.7.9.tar.gz'
tar xvf jruby-bin-1.7.9.tar.gz
cd ~
mkdir neo4j
cd neo4j
wget -O neo4j-community-2.0.0.tgz 'http://download.neo4j.org/artifact?edition=community&version=2.0.0&distribution=tarball'
tar xvf neo4j-community-2.0.0.tgz
Next, clone the napkin code from github:
cd ~
git clone https://github.com/cjdaly/napkin.git
Now add java, neo4j and jruby to the path, and confirm each one gives a reasonable version/status message.
source ~/napkin/server/sinatra/server-setup.sh
Install gems used by Napkin:
gem install --no-rdoc --no-ri rest-client sinatra json kramdown
cd ~/napkin/server/sinatra
source server-setup.sh
./napkin.sh -start systems/ubuntu-x86
tail -f napkin.log
./napkin.sh -status
./napkin.sh -stop
