4store-service: a script to start, stop and restart 4store

4s-service-setup.sh

# Setup for usage in Mac OSX (assuming you are using 4store.app from your /Applications folder)
curl -L https://raw.github.com/gist/4211360/81143f15fd6f9a3defcd38b6c24a922f3fc731ac/gistfile1.sh -o 4s-service
chmod +x 4s-service
mv 4s-service /Applications/4store.app/Contents/MacOS/bin
# Add the following to your (zsh|bash)rc path (this makes it so you don't have to run 4store.app):
# export PATH=/Applications/4store.app/Contents/MacOS/bin:$PATH
# You can also do this for custom installs of 4store, just replace the /Applications path with your own
# THE SCRIPT WILL NOT WORK WITHOUT 4s-backend, 4s-httpd, etc IN YOUR PATH

# Defaults:
PORT=9000
KB=test

# Invoke 4s-service as follows:
4s-service start
4s-service start -p 8080 # custom port
4s-service start -k demo # custom knowledgebase
4s-service start -p 8080 -k demo
4s-service stop
4s-service restart # restarts running kbs/httpds with custom options

# Linux startup script for 4store
# chkconfig: 2345 99 20
# description: Run an 4store backend and sparql http server
# processname: 4store
#
# To install, configure this file as needed and copy
# to /etc/rc.d/init.d as 4store. Then use "# /sbin/chkconfig 4store reset"

# Based on Michael Grove's script for 4store-api:
# https://github.com/mhgrove/4Store-API

# This script is incredibly naive.
# 1) Only tested on OSX Mountain Lion
# 2) For restarting, it inspects running processes and then
#    attempts to run the same ones again.
# 3) It relies on sorting alphabetically to run 4s-backend before 4s-httpd.
#    It does this in an attempt to preserve custom settings:
#       IE 4s-service -p 8080 -k demo
# 4) It will also kill every instance of backend and httpd that is running.
