Automate Grid Startup

Windows

Create a batch file to start up your grid, e.g. startGrid.bat ;

 @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
:: If you run a 64-bit Windows, with OpenSim as a 32-bit
:: application, substitute with %PROGRAMFILES(X86)%

Echo Starting User Server...
start "UserServer" /MIN /D "%PROGRAMFILES%\OpenSim" OpenSim.Grid.UserServer.exe
sleep 5
Echo Starting Grid Server...
start "GridServer" /MIN /D "%PROGRAMFILES%\OpenSim" OpenSim.Grid.GridServer.exe
sleep 5
Echo Starting Asset Server...
start "AssetServer" /MIN /D "%PROGRAMFILES%\OpenSim" OpenSim.Grid.AssetServer.exe
sleep 5
Echo Starting Inventory Server...
start "InventoryServer" /MIN /D "%PROGRAMFILES%\OpenSim" OpenSim.Grid.InventoryServer.exe
sleep 5
Echo Starting Messaging Server...
start "MessagingServer" /MIN /D "%PROGRAMFILES%\OpenSim" OpenSim.Grid.MessagingServer.exe
sleep 5
Echo Starting Region Server...
start "RegionServer" /MIN /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

For /F "Usebackq" %%i In (`Tasklist ^| Find /C "OpenSim"`) Do If /I %%i EQU 0 Echo There are no OpenSimulator processes running. Nothing to stop.. & Goto END

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)

Simulator Watchdog

Watches the simulator process under Linux

Adding an entry to call a simple script to check the process table can restart regions that crash to the command line. Here User_talk:BlueWall is a script to accomplish this with a sample cron entry for one minute intervals. While it will not fix 100% of the crashes, it will get most cases, and help keep the grid healthy. If you have questions, you can usually find me on irc.freenode.net #opensim or #osgrid

Automate Updates

Linux (CentOS-5)

This script will save your settings, grab the latest release of OpenSim, build OpenSim, and restore your settings to the new release. It creates the new release in a new directory allowing you to revert to the previous release by just changing the 'current' link to point to whichever release you want to run.

This script assumes you are using the SVN release number as the OpenSim directory with a link called 'current' pointing to it. So, you might, for example, have a directory called '/home/opensim/7577' and a link 'current -> 7577'. This script also uses a save folder for moving settings from the old release to the new.

You will also want to compare the 'OpenSim.ini' and the 'OpenSim.ini.example' by hand after running this update script. There are often changes in this file needed for the new release. The 'diff -bB' command helps a lot in this comparison.

#!/bin/bash -x

CWD=`pwd`
MWD="/home/opensim"  # Main Working Directory (change appropriately)
SAVEDIR="$MWD/save"  # Save Directory

if [ ! -d $SAVEDIR ]; then mkdir $SAVEDIR; fi
if [ ! -d $SAVEDIR/Regions ]; then mkdir $SAVEDIR/Regions; fi
if [ ! -d $SAVEDIR/DataSnapshot ]; then mkdir $SAVEDIR/DataSnapshot; fi

cd $MWD

# Save current settings
cp current/bin/estate_settings.xml $SAVEDIR
cp current/bin/*.db $SAVEDIR
cp current/bin/ImageService.dll $SAVEDIR
cp current/bin/OpenSim.ini $SAVEDIR
cp current/bin/LaunchSLClient.ini $SAVEDIR
cp current/bin/Regions/*xml $SAVEDIR/Regions/
cp current/bin/DataSnapshot/*xml $SAVEDIR/DataSnapshot/

# Get fresh copy of OpenSim
REV=`svn info http://opensimulator.org/svn/opensim/trunk | fgrep Revision | awk '{print $2}'`
svn -r $REV co http://opensimulator.org/svn/opensim/trunk $REV
# Repoint the 'current' link to the new release
rm current
ln -s $REV current
cd current
# Build OpenSim
./runprebuild.sh
nant
cd bin

# Restore settings
if ![ -d ./DataSnapshot ]; then mkdir ./DataSnapshot; fi
cp $SAVEDIR/estate_settings.xml .
cp $SAVEDIR/*.db .
cp $SAVEDIR/ImageService.dll .
cp $SAVEDIR/OpenSim.ini .
cp $SAVEDIR/LaunchSLClient.ini .
cp $SAVEDIR/Regions/*.xml Regions/
cp $SAVEDIR/DataSnapshot/*.xml DataSnapshot/

cd $CWD
