Solution for some problems

  • port conflicts

Modify configuration in './game-server/config/server.json':

{
  "development": {
    "connector": [
    {"id": "connector-server-1", "host": "127.0.0.1", "port": 3150, "clientPort": 3010, "frontend": true},
    {"id": "connector-server-2", "host": "127.0.0.1", "port": 3151, "clientPort":3011, "frontend": true}
    ],
  "area": [
    {"id": "area-server-1", "host": "127.0.0.1", "port": 3250, "area": 1},
    {"id": "area-server-2", "host": "127.0.0.1", "port": 3251, "area": 2},
    {"id": "area-server-3", "host": "127.0.0.1", "port": 3252, "area": 3}
  ],
  "chat": [{"id":"chat-server-1","host":"127.0.0.1","port":3450}],
  "path": [{"id": "path-server-1", "host": "127.0.0.1", "port": 3550}],
  "auth": [{"id": "auth-server-1", "host": "127.0.0.1", "port": 3650}],
  "gate": [{"id": "gate-server-1", "host": "127.0.0.1", "clientPort": 3014, "frontend": true}]
 },
  "production": { }
}

This file regulates the servers configuration information, such as serverType, serverId, host, port etc. The configuration information in production is similar with development, and the frontend is the flag for frontend server.

Also you can modify configuration of '/web-server/public/js/config/config.js':

IMAGE_URL: "http://pomelo.netease.com/art/",
GATE_HOST: window.location.hostname,
GATE_PORT: 3014

This is the most common configuration for web server. You can get static resources like images by IMAGE_URL. GATE_HOST is the access of websocket request which gets the connectorId from gate server and connects to connector server. GATE_PORT is the port of gate server.

Details for configurations

  • ./game-server/config/master.json

This file is about master server configuration, including serverId, host etc both in development and production. The master server is responsible for starting and closing other servers, and also in charge of monitoring state information of them.

  • ./game-server/config/servers.json

The configuration information for area, connector and status server in all environments. The connector server has websocket port parameter because it needs to communicate with clients through websocket.

  • ./shared/config/mysql.json

The database configuration information. You should modify the configuration parameters after installing lordofpomelo in development environment.

  • ./web-server/public/js/config/config.js

This is the most common configuration composed of IMAGE_URL, GATE_HOST and GATE_PORT for web server.

Supplementary for login

Not only can you create a new account, but also use account of github, google, facebook, twitter and sina weibo after authorized to access to lordofpomelo. Of course, you should get the authority and modify the configuration parameters locating in './web-server/config/oauth.json'.

Something went wrong with that request. Please try again.
