Installation of MySQL and configuration of Opensim.ini

Download MySQL from http://www.mysql.com. The community version (free version) is available in the download section. Running the setup is straightforward.

Once MySQL is up-and-running you have to create a database. I called mine Opensim (original name, isn’t it?). No tables have to be defined in this database, but verify that the user used to connect to the database has the correct rights.

Next you have to edit the Edit the mysql_connection.ini file. Put in the connection information.

The last step is to edit the Opensim.ini file. This is described at http://opensimulator.org/wiki/Mysql-config

The configuration settings for MySQL are available at http://opensimulator.org/wiki/OpenSim_Database_support

Installation on MS SQL is described at http://metaversebuilders.wordpress.com/2008/06/23/opensim-installation-part-two/ and a tutorial to download and install mySQL is available at http://www.virtualwhite.com/?p=13

Using OpenSim Standalone Mode

Once downloaded and installed OpenSim, just start the executable Opensim.exe , in the /bin/ directory. You have to answer several questions (see http://opensimulator.org/wiki/OpenSim_Configuration for more information) the first time you start Opensim. This information is stored in the Opensim.ini file, which you can always change later.

Once opensim is started, you can log from any PC with the Secondlife Viewer. But first you need to change the firewall settings. Open Port 9000. if you plan to run OpenSim in Grid Mode, you also have to open port 8002.

Control Panel

Next you have to create an new icon on your desktop that launches second life with several parameters:

Secondlife icon

“C:\Program Files\SecondLife\SecondLife.exe” -set SystemLanguage en-us -loginuri http://x.x.x.x:9000/ -loginpage http://x.x.x.x:9000/?method=login, where x.x.x.x is the IP address of the computer that runs OpenSim.exe

Hardware configuration

To install OpenSim, I did a clean install of Windows 2008 SP1 on a Intel Pentium 4 3.2 Ghz with 2Gb of RAM. Because I don’t have enough (physical) space or spare monitor, I access the PC with remote desktop.

I am not the first one that tries to install OpenSim on a Windows 2008 OS: Check http://www.youtube.com/watch?v=6hFYCTKRbGM

Downloading OpenSim

philkerr — Sun, 10 Aug 2008 10:17:43 +0000

The main website for OpenSim is http://www.opensimulator.org. I choose to install a compiled version, which is available at http://opensim.be/build/

I just had to unzip it and place it in an directory, \program files\opensim\opensim-0.5.8\ in my case.

This blog will describe all my opensim activities. OpenSim is an open source version of Second Life. When Linden Lab has made the SecondLife viewer open source, people have reverse engineered given the knowledge acquired for the SecondLife viewer.
