Installing the backend

The launcher server uses DotNet version 8.0. You need to install this software on your VPS. In addition, you need to deploy a MySQL database (MariaDB) and configure it.

Installing dotnet 8.0:

sudo apt update 
wget -q https://packages.microsoft.com/config/ubuntu/22.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt update
sudo apt install -y dotnet-sdk-8.0

Installing MySql:

apt update
sudo apt install mariadb-server 
sudo systemctl start mariadb.service
mysql 
CREATE USER 'launcher'@'%' IDENTIFIED BY 'YOUR PASSWORD';
GRANT ALL PRIVILEGES ON *.* TO 'launcher'@'%' WITH GRANT OPTION;
CREATE DATABASE launcher;

You may also need an nginx server if you don't have one:

apt install nginx
