4.3 Config setup for multiple servers across different VPS's

Initial Assumptions

Assume that:

• I have 2 VPS.

  • The first VPS public address is 199.222.32.3

  • The first VPS local IP is 123.456.78.9 (you can find this by opening a command prompt and using ipconfig)

  • The second VPS public address is 182.243.34.5

  • The second VPS local IP is 987.543.21.1 (you can find this by opening a command prompt and using ipconfig)

• My client version is 1.1.1 (i.e. I did not modify it through the client tools as explained in the next chapters)

• The database is placed inside the first VPS, and is named microvolts-db

• My database username is root

• My database password is stored in the environment variable named "MV_DB_PW" (inside the first VPS)

• My MariaDB runs on port 3305 (inside the first VPS)

• I do not have a website running (i.e. no admin panel)

• Both VPS allow incoming connections to all the ports below through firewall settings

• Both VPS allow incoming and outgoing connections from/to each other. Then, here's a simple setup for a VPS:

Initial setup

The first VPS must contain:

• The auth server executable.
• The main server for the first VPS executable.
• The cast server for the first VPS executable.
• The main server for the second VPS executable.

The second VPS must contain:

• Only the cast server.

To be sure of the setup in all VPS, just copy paste the emulator in all of them. But make sure that:

• Once "central" VPS runs the Auth server and all main servers (even those for other regions).
• Each VPS runs its own cast server.
• Basically: the central VPS runs the auth server, all main servers and its own cast server. All other VPS's run only their respective cast servers.
