How to run multiple server instances at the same time?

[thaalesalves]

Hello! This question is self-explicative;

Everytime I try to run more than one instance at the same time, the main instance stops working... the database gets corrupted, so I have to make the server all over again, room by room, group by group; Even changing the ports (query, FTP and voice ports), it happens...
does anyone know how to help me?

You need to
1) Use different database for every instance

ts3db_mysql.ini
[config]
host=localhost
port=3306
username=root
password=password
database=ts3
socket=

You can use command line parameter dbpluginparameter=......./ts3-server.mysql.instance1 (read howto about dbpluginparameter) pointing to different files for each instance
2) Have a license that allows you running multiple instances (it is PAID licence)

You also could use the machine_id.

machine_id (<empty>)
  Optional name of this server process to identify a group of servers with
  the same ID. This can be useful when running multiple TeamSpeak 3 Server
  instances on the same database. Please note that we strongly recommend that
  you do NOT run multiple server instances on the same SQLite database.
  Default: The server instance will not use a machine ID.
