Plugin Setup

Download and Install the MySQL Player Data Bridge plugin.

Download MySQL Player Data Bridge

Download the MySQL Player Data Bridge plugin on SpigotMC .

Upload the file to the server using SCP, SFTP, or SSH. If using a hosting provider, you may be able to do this with the web interface.

The following command is an example using scp, replace the values as required.

• $HOME/Downloads/MysqlPlayerDataBridge-v4.11.0.jar: Path to the plugin file, verify it and the version number are correct.
• serveruser: User with SSH capabilities on the Minecraft server.
• 192.168.1.255: Hostname or IP address of the server.
• /tmp: Where to copy file, this guide will assume it is copied to the /tmp directory.
• -i $HOME/.ssh/path-to-private-key: Private key file to use for authentication.

Password Example

scp $HOME/Downloads/MysqlPlayerDataBridge-v4.11.0.jar [email protected]:/tmp

Private Key Example

scp $HOME/Downloads/MysqlPlayerDataBridge-v4.11.0.jar [email protected]:/tmp -i $HOME/.ssh/path-to-private-key

Install MySQL Player Data Bridge

On the Minecraft server, copy the plugin file to the plugins directory within the Minecraft server directory.

cp /tmp/MysqlPlayerDataBridge-v4.11.0.jar /opt/minecraft/server/plugins/

Modify the file permissions as required.

chown minecraft:minecraft /opt/minecraft/server/plugins/MysqlPlayerDataBridge-v4.11.0.jar

chmod 640 /opt/minecraft/server/plugins/MysqlPlayerDataBridge-v4.11.0.jar

Restart Minecraft to generate the configuration files for MySQL Player Data Bridge.

sudo systemctl stop minecraft && sudo systemctl start minecraft

Configure MPDB

Open the MPDB configuration file in an editor. The configuration file is well-commented and should be reviewed fully to get the most out of the plugin. Find the config.yml file in the plugins/MysqlPlayerDataBridge directory.

nano /opt/minecraft/server/plugins/MysqlPlayerDataBridge/config.yml

    #MySQL server address
    host: 127.0.0.1
    #MySQL server port (default 3306)
    port: 3306
    #Database name (NOTE! You need to create the database, then the plugin will create the tables.)
    databaseName: 'mpdb'
    #Tables names (the plugin will auto create them)
    TablesNames:
      #Inventory and Armor table name.
      inventoryTableName: 'mpdb_inventory'
      #Enderchest table name.
      enderchestTableName: 'mpdb_enderchest'
