MuServer is the set of programs that make the game run. Understanding each one's role is essential to configure and troubleshoot.

The MuServer components

ServiceFunction
ConnectServerReceives the player and lists available servers
JoinServerManages accounts and login
GameServerWhere the game actually happens (maps, monsters, drops)
DataServerBridges the GameServer and SQL
Nota: Startup order matters: usually DataServer/JoinServer first, then ConnectServer and finally the GameServer.

Step 1 — Point to the database

In the config files, set the SQL address, database name and the user created in the SQL tutorial.

Step 2 — Set IP and ports

Configure the ConnectServer IP (127.0.0.1 for tests) and each service's ports. Note them: you'll need them to open the firewall.

[ConnectServer]
ServerAddress = 127.0.0.1
Port = 44405

Step 3 — Adjust the server rates

This is where you define your server's "personality": EXP (leveling speed), Drop (item chance), Reset (level and bonus), Events (which are active).

Dica: For a new server, moderate rates retain players better than extreme ones. Very high EXP empties the content too fast.

Step 4 — Start and test

Start the services in the right order, connect with the client at 127.0.0.1, and validate login, character creation, drop and save.

Atenção: If the GameServer closes by itself when opening, check its log: it's almost always a DataServer/SQL connection failure or a port already in use.

Perguntas frequentes

What is ConnectServer?

It's the service that receives the player and directs them to the correct GameServer. It's the client's first point of contact with the server.

Can I have multiple GameServers?

Yes. Larger servers use subservers to spread the load, each with its own port, all connected to the same database.
