OpenSim on Gentoo Linux

OpenSim - The open source virtual world simulator

Annuna Technologies is participating in the OpenSim project - helping with the development of an Open Source Simulator.

• OpenSim entry at OpenMetaverse (OpenSL project)
• Open Grid Services - homepage of OGS project

Try it yourself

Just call your Second Life client with the following additional parameter:

 C:\Programme\SecondLife\SecondLife.exe -loginuri http://grid.annuna.net:7002/

For keeping things easy you should use the regular SL client and not the FirstLook viewer.

Simply use the following user information for login:

• Username: Annuna Testuser
• Password: letmein

OpenSim on Gentoo Linux

Installation

For compiliting and installing the OpenSim source you eventually need to pre-install some additional software packages. You also need a typical LAMP installation which will not be explained here.

 $ emerge dev-lang/mono
 $ emerge dev-dotnet/nant
 $ emerge dev-util/subversion

Copy the newest subversion tree containing the OpenSim source code to your local directory:

 $ cd
 $ svn co svn://opensecondlife.org/opensim/trunk opensim
 [...]
 Checked out revision 8624.
 $ mv opensim opensim_r8624

Release number 8624 is only an example. I usually use the release number for renaming the related directory. That way I can have several different releases on my harddisk.

 $ cd opensim_r8624
 $ ./runprebuild.sh
 [...]
 $ nant
 [...]

Configuration

The following files need to be configured or at least (when updating) copied from the old release directory tree to the newly created directories.

• opensim_rXXXX/bin/OpenSim.ini
• opensim_rXXXX/bin/LaunchSLClient.ini
• opensim_rXXXX/bin/mysql_connection.ini
• opensim_rXXXX/bin/Regions/Central_Plaza.xml (my opensim region is called 'Central Plaza')
• opensim_rXXXX/bin/UserServer_Config.xml
• opensim_rXXXX/bin/GridServer_Config.xml
• opensim_rXXXX/bin/AssetServer_Config.xml
• opensim_rXXXX/bin/InventoryServer_Config.xml
• opensim_rXXXX/bin/MessagingServer_Config.xml
• opensim_rXXXX/bin/OpenSim.db

A good help for automatically updating configuration files after updating the program system can be found here.

Startup

It is a good idea to use screen for starting all the different threads of the opensim package:

 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 MessagingServer -d -m mono OpenSim.Grid.MessagingServer.exe
 sleep 3
 screen -S OpenSim -d -m mono OpenSim.exe -gridmode=true
