Automate Grid Startup

Windows

@Echo OFF

For /F "Usebackq" %%i In (`Tasklist ^| Find /C "OpenSim"`) Do If /I %%i GTR 0 Echo There are %%i OpenSimulator processes running already. I quit! & Goto END

:: %PROGRAMFILES% expands to your normal application path
:: On an English system this is normally C:\Program Files

Echo Starting User Server...
start "UserServer" /D "%PROGRAMFILES%\OpenSim" OpenSim.Grid.UserServer.exe
sleep 5
Echo Starting Grid Server...
start "GridServer" /D "%PROGRAMFILES%\OpenSim" OpenSim.Grid.GridServer.exe
sleep 5
Echo Starting Asset Server...
start "AssetServer" /D "%PROGRAMFILES%\OpenSim" OpenSim.Grid.AssetServer.exe
sleep 5
Echo Starting Inventory Server...
start "InventoryServer" /D "%PROGRAMFILES%\OpenSim" OpenSim.Grid.InventoryServer.exe
sleep 5
Echo Starting Region Server...
start "RegionServer" /D "%PROGRAMFILES%\OpenSim" OpenSim.exe -gridmode=true

:END

PS! Check that you have sleep command installed, I'm unsure if all Windows versions have that.
If sleep is not installed one can use a localhost ping instead to replace "sleep 3".

PING -n 4 127.0.0.1>nul

This knowledgebase article describes how to add a batch file to startup of Windows (before logon).
http://support.microsoft.com/kb/q243486/
Note that you have to start all applications and answer the configuration questions once before adding it to any startup.

If you start the server before logon then there will be no window to close if you want to shut down the server, so you can create a "StopGrid.BAT" with:

taskkill /FI "IMAGENAME eq OpenSim.*"
sleep 3
taskkill /FI "IMAGENAME eq OpenSim.*"
sleep 3
taskkill /F /FI "IMAGENAME eq OpenSim.*"

Or a more advanced batch that shut server processes down in the opposite order as recommended in the manual.

@Echo OFF

Linux/Mac OS X

You can use this startup script

• Use Screen Command

Use the screen command to automate startup

• Setup screen command and setup shell file

Linux install:

apt-get install screen (ubuntu)
pacman -S screen (archlinux)

Mac OS X: Download either MacPorts, http://www.macports.org/, or Fink, http://www.finkproject.org/ to download *nix packages MacPorts

sudo port install screen

Fink

Need command line for Fink.

• Create file runsim.sh

#!/bin/sh
cd opensim/bin
sleep 3
screen -S UserServer -d -m  mono OpenSim.Grid.UserServer.exe
sleep 3
screen -S GridServer -d -m mono OpenSim.Grid.GridServer.exe
sleep 3
screen -S AssetServer -d -m mono OpenSim.Grid.AssetServer.exe
sleep 3
screen -S InventoryServer -d -m mono OpenSim.Grid.InventoryServer.exe
sleep 3
screen -S OpenSim -d -m mono OpenSim.exe -gridmode=true

Startup and access servers

./runsim.sh

If you have permission issues

chmod 755 runsim.sh

To see a list of the servers in screen:

screen -ls or screen -list

Output will look like the following:

There are screens on:
     8419.OpenSim  (Detached)
     8403.InventoryServer  (Detached)
     8378.AssetServer  (Detached)
     8360.GridServer  (Detached)
     8347.UserServer  (Detached)

To access server

screen -r 8419.OpenSim
screen -r 8403.InventoryServer
etc.

To exit screen, leaving server running, and to return to shell

ctrl-a d

Shutdown Servers

Either manually access each sceen

screen -r 8419.OpenSim
shutdown

Or use

killall mono

Or

for i in `ps afxu | grep -i "mono.*OpenSim" | grep -v grep | awk {'print $2'}`; do kill $i; done

Or to shut down each session clean, make a stop script, stopgrid.sh

#!/bin/bash
screen -S InventoryServer -X eval "stuff shutdown^M"
sleep 5
screen -S AssetServer -X eval "stuff shutdown^M"
sleep 5
screen -S GridServer -X eval "stuff shutdown^M"
sleep 5
screen -S UserServer -X eval "stuff shutdown^M"

This depends on the screen NAME to be the same as in the startup script described above! --Suz 01:42, 18 May 2008 (PDT)
