In general, the following options are necessary for users to modify according to actual situations,

• database.mysql.username: the username of MySQL
• database.mysql.password: the user's password of MySQL
• database.mysql.database: the database used for X-LoRa in MySQL
• udp.port: the port for receiving UDP packets from LoRa Gateways(default value is 1700)
• http.port: the port of HTTP interfaces(default value is 3000)

Other configurations are free to change to fit the environments.
