Install OpenSim 0.9.3.0 in Grid mode on Ubuntu 24.04

Nov 17, 2024

—

In this guide, I’ll walk you through configuring OpenSim 0.9.3.0 in grid mode on Ubuntu 24.04. For the database setup, we’ll use the user opensim with the password DB_Password. Feel free to customize these credentials as needed. Also, remember to replace domain.com with your actual domain name throughout the configuration.

Dependency Installation

Before installing OpenSim, you need to install .Net, MySQL, unzip and screen. Run the following commands:

sudo apt update
sudo apt dist-upgrade
sudo apt install libgdiplus dotnet-sdk-8.0 mysql-server unzip screen

MySQL configuration

Next, configure MySQL by editing the MySQL configuration file:

sudo nano /etc/mysql/my.cnf

Add the following lines after !includedir /etc/mysql/mysql.conf.d/:

[mysqld]
default_storage_engine = InnoDB
disable_log_bin
innodb_buffer_pool_size = 2G
innodb_log_file_size = 256M
innodb_log_buffer_size = 16M
innodb_flush_method = O_DIRECT
innodb_flush_log_at_trx_commit = 0
innodb_buffer_pool_instances = 2
default-authentication-plugin=mysql_native_password

Restart MySQL:

sudo service mysql restart
sudo mysql_secure_installation -u root -p

Database creation

Create the OpenSim database and user:

sudo mysql

Within the MySQL shell, run:

mysql> CREATE DATABASE opensim;
mysql> CREATE USER opensim IDENTIFIED BY 'DB_Password';
mysql> GRANT ALL PRIVILEGES ON opensim.* TO 'opensim';
mysql> FLUSH PRIVILEGES;

Verify the opensim account’s authentication method is mysql_native_password:

mysql> SELECT user,authentication_string,plugin,host FROM mysql.user;
mysql> \q

Download and Extract OpenSim

Download and unzip the latest OpenSim build:

cd ~
wget http://opensimulator.org/dist/opensim-0.9.3.0.zip
unzip opensim-0.9.3.0.zip

Grid configuration

Navigate to the configuration directory:

cd ~/opensim/bin
cp Robust.HG.ini.example Robust.HG.ini
cp config-include/GridCommon.ini.example config-include/GridCommon.ini
cp config-include/osslEnable.ini.example config-include/osslEnable.ini

Edit Robust.HG.ini:

nano -c ~/opensim/bin/Robust.HG.ini

Edit the lines 27 – 268 – 652 – 655 – 872
Uncomment 132 – 134 – 139 – 219 – 226 – 767

	[UserAgentService]
767		ShowUserDetailsInHGProfile = True
	
	[UserProfilesService]
872		Enabled = true

Launch Robust

Start the Robust server to check for errors:

dotnet ~/opensim/bin/Robust.dll -inifile=Robust.HG.ini

Create the first user in the Robust console:

R.O.B.U.S.T.# create user
First name [Default]: Ludo
Last name [User]: Davis
Password:
Email []:
User ID (enter for random) []:
Model name []:

Quit the Robust console:

R.O.B.U.S.T.# quit

Edit OpenSim.ini

Next, configure OpenSim.ini:

nano -c ~/opensim/bin/OpenSim.ini

Edit the lines: 53 – 1210 – 1225 – 1187 – 1248

Edit GridCommon.ini

Now, edit GridCommon.ini:

nano -c ~/opensim/bin/config-include/GridCommon.ini

Edit the line19
Uncomment 16 – 49

	[Hypergrid]
49		GatekeeperURI = "${Const|BaseURL}:${Const|PublicPort}"

Start the Servers

Start the Robust server in a detached screen session:

screen -dmS "Robust" dotnet Robust.dll -inifile=Robust.HG.ini

Then start OpenSim:

screen -dmS "OpenSim" dotnet OpenSim.dll

Accessing the Screen Sessions

To reconnect to your running servers, use:

screen -d -r Robust
screen -d -r OpenSim

To detach from the screen, always use Ctrl + A followed by D.

Firewall configuration

If you’re using UFW as your firewall, be sure to configure it to allow the necessary ports.
If you haven’t installed it, you can skip this step.

sudo ufw allow "OpenSSH"
sudo ufw allow 8002/tcp
sudo ufw allow 9000/tcp
sudo ufw allow 9000:9100/udp
sudo ufw enable

Conclusion

Your OpenSim grid should now be running smoothly! Feel free to reach out if you encounter any issues or have questions about the setup.

It says about posting domain as if looking for a web site address. What if there is no web site?

  You don’t need a website—just a domain name (DNS) that points to your IP.
  
  A domain makes it easier for people to find and remember you on the grid, rather than using a string of numbers. Plus, if you ever switch server providers and your IP changes, your domain stays the same!
