i was unable to find a proper System V type startup script for Servoy application server, so I wrote my own (actually, pasted together bits and pieces from other scripts).
With this script you can start and stop the application server and query if it's running. Also you can use chkconfig to turn the service on/off. Runlevel changes should work nicely too.
One problem with the script is that there is no "nice" way of shutting down the application server from unix shell? Let's hope it is implemented soon. I'm just killing the processes. This could be disastrous, so the server should still be shut down from the administration console if possible.
All comments are welcome. Especially I wonder if using "kill" to shut down the server really can break something...
DISCLAIMER: Use the code with your own responsibility. Please understand what you're doing, take backups and and test everything before installing it on your production server.
Installation:
AS ROOT..
1) save the script below as /etc/init.d/servoy
2) edit the script to ensure all the variables are correct: SRVUSER = your system's user name to run servoy under, SERVOY_ROOT = servoy installation directory, SERVOY_EXEC = complete path to servoy startup script (servoy_server.sh)
3) edit the servoy_server.sh script to include user dir so the server can find the preferences file. Add "-Duser.dir=$HOME/servoy" just after the word "java".
4) make sure you have created a user account for servoy. Important: you shouldn't run any other processes than servoy application server under this user id.
5) try starting, stopping and restarting the server, like this:
- Code: Select all
# /etc/init.d/servoy start
Starting Servoy services: [ OK ]
# /etc/init.d/servoy restart
Shutting down Servoy services: [ OK ]
Starting Servoy services: [ OK ]
# /etc/init.d/servoy stop
Shutting down Servoy services: [ OK ]
# /etc/init.d/servoy status
application server is not running
.. and verify with your browser that the server really has started and stopped.
6) if everything seems to work you can now say chkconfig servoy on to install servoy as a service, that starts and stops automatically during runlevel changes (reboot, etc).
Here is the script:
- Code: Select all
#! /bin/sh
#
# System startup info for chkconfig
#
# chkconfig: 35 95 5
# description: Starts and stops the Servoy application server
#
# System startup script for the Servoy Application Server
# Verify SRVUSER, SERVOY_ROOT and SERVOY_SERVER and place in /etc/init.d
