Configuring Regions
From OpenSimulator
Contents[hide] |
OpenSimulator 0.7 and later
By default, regions are configured in a file named Regions.ini in the bin/Regions directory. If you started a completely fresh installation of OpenSim, it will ask you a series of questions to set up your first region.
Here's an example of a Regions.ini file
[Big Fat Region] RegionUUID = 5ce85740-6460-43d3-ba4c-29207b010072 Location = 1000,1000 InternalAddress = 0.0.0.0 InternalPort = 9000 AllowAlternatePorts = False ExternalHostName = 192.168.1.2
This is a list of settings that must be present for a region to operate. When you start OpenSimulator for the first time without an existing Regions.ini file, you'll be asked for an entry for each setting in order to set up your initial region. For more details, see Configuration#Running OpenSimulator for the first time.
If you want to add another region you can
- enter another section in Regions.ini
- create another separate .ini file in bin/Regions
- create an old format OpenSimulator xml file (these still work with current OpenSim)
- or use the create region command on the region console (I don't recommend this since it seems to be a bit buggy).
Here's an example where a second region has been added to Regions.ini
[Big Fat Region] RegionUUID = 5ce85740-6460-43d3-ba4c-29207b010072 Location = 1000,1000 InternalAddress = 0.0.0.0 InternalPort = 9000 AllowAlternatePorts = False ExternalHostName = 192.168.1.2 [Greek Wedding] RegionUUID = 5c445740-6460-43d3-ba4c-444444445555 Location = 1000,1001 InternalAddress = 0.0.0.0 InternalPort = 9001 AllowAlternatePorts = False ExternalHostName = 192.168.1.2
As you can see, the Second region is named Greek Wedding and has a different UUID. It has a different location (1000,1001) and a different InternalPort (9001). Other than that, the details are the same.
To create a new UUID you can either tweak an existing one by hand (e.g. by changing one character so that the new one is in the range [0-9][A-F] or a generator can be found at uuidgen webpage. On Unix, you can also use the uuidgen command.
As well as the critical entries above, there are some additional optional ones that can change the properties of a region. These are
Other Tasks
Configuring Multiple Regions on a Single Server Instance
To configure multiple regions on one server (i.e. a 4x4 server), edit the Regions.ini file to include multiples of the single entry already there. Make sure the RegionUUID and InternalPort are different on each one, or it won't work. To load individual OAR files into each region, use the 'change region [regionname]' command and then 'load oar [oar-location]'.
Loading from the web
OpenSim.exe can read the region definitions from the web using the following settings :
[Startup] region_info_source = "web" regionload_webserver_url = "http://example.com/regions.xml";
The following format has been reported to work with OpenSimulator 0.8.* :
<Nini> <Section Name="My region Name"> <Key Name="RegionUUID" Value="4208aa66-ce9b-4f49-a4da-06a27d95f001" /> <Key Name="Location" Value="7000,7000" /> <Key Name="InternalAddress" Value="0.0.0.0" /> <Key Name="InternalPort" Value="9016" /> <Key Name="AllowAlternatePorts" Value="False" /> <Key Name="ExternalHostName" Value="mygrid.org" /> <Key Name="MaxPrims" Value="15000" /> <Key Name="MaxAgents" Value="40" /> <Key Name="RegionType" Value="0" /> <Key Name="SizeX" Value="256" /> <Key Name="SizeY" Value="256" /> <Key Name="MaptileStaticUUID" Value="00000000-0000-0000-0000-000000000000" /> </Section> </Nini>
OpenSimulator 0.6.7 to OpenSimulator 0.6.9
By default, regions are configured in a file named Regions.ini in the bin/Regions directory. If you started a completely fresh installation of OpenSim, it will ask you a series of questions to set up your first region.
Here's an example of a Regions.ini
[Big Fat Region] RegionUUID = 5ce85740-6460-43d3-ba4c-29207b010072 Location = 1000,1000 InternalAddress = 0.0.0.0 InternalPort = 9000 AllowAlternatePorts = False ExternalHostName = 192.168.1.2 MasterAvatarFirstName = Justin MasterAvatarLastName = Clark-Casey MasterAvatarSandboxPassword = yeahokay
This is the list describing the relation between the entries in Regions.ini and the questions during setup. For detail about each question, see Configuration#Running OpenSimulator for the first time.
If you want to add another region you can
- enter another section in Regions.ini
- create another separate .ini file in bin/Regions
- create an old format OpenSimulator xml file (these still work with OpenSimulator 0.6.7)
- or use the create region command on the region console (I don't recommend this since it seems to be a bit buggy in 0.6.7).
Here's an example where a second region has been added to Regions.ini
[Big Fat Region] RegionUUID = 5ce85740-6460-43d3-ba4c-29207b010072 Location = 1000,1000 InternalAddress = 0.0.0.0 InternalPort = 9000 AllowAlternatePorts = False ExternalHostName = 192.168.1.2 MasterAvatarFirstName = Justin MasterAvatarLastName = Clark-Casey MasterAvatarSandboxPassword = yeahokay [Greek Wedding] RegionUUID = 5c445740-6460-43d3-ba4c-444444445555 Location = 1000,1001 InternalAddress = 0.0.0.0 InternalPort = 9001 AllowAlternatePorts = False ExternalHostName = 192.168.1.2 MasterAvatarFirstName = Justin MasterAvatarLastName = Clark-Casey MasterAvatarSandboxPassword = yeahokay
As you can see, the Second region is named Greek Wedding and has a different UUID. It has a different location (1000,1001) and a different InternalPort (9001). Other than that, the details are the same.
To create a new UUID you can either tweak an existing one by hand (e.g. by changing one character so that the new one is in the range [0-9][A-F] or a generator can be found at uidgen webpage. On Unix, you can also use the uuidgen command.
OpenSimulator 0.6.6 and earlier
For running multiple regions on the same box, you simply make multiple copies of the 'default.xml' file inside the bin/Regions/ directory. You can do this by typing create region at the OpenSimulator command prompt, using the script make.php in share/regions, or you can generate the files by hand.
If you want to create the files by hand:
- first copy the default.xml file in the bin/Regions directory, and name them anything you want (I name mine region.x.y.xml, where region is the name of the region, and x and y are the grid coords.)
- Open each xml file and edit the uuid (a generator can be found at uuidgen webpage or on unix, use the uuidgen command), region name, x & y positions, and internal IP port.
IMPORTANT! Regardless of the method you use to create your new region, the UUID, name, and grid coordinates must be unique for each region on a grid. The port assignment must be unique for each region that is running on a particular machine. The internal IP address and external host name must be the same for all regions.
Note that sim_location_x and sim_location_y should be adjacent integers if you want your regions to be adjacent, so you can run back and forth between them. IMPORTANT: THESE GRID COORDINATES ARE NOT IN METERS. THEY ARE SIM POSITIONS. (1000, 1000) is next to (1001,1000), (1000, 1001), and so forth. 1256, 2000, 2048 and similar values are not adjacent to 1000, they are very far away, so you would not see your sims from one another.
Once you have 2 or more xml files in the bin/Regions folder, running a single copy of OpenSim.exe will start up all of your sims! If you come across any errors, there is most likely an error in your xml files.
