gFirefly 學習筆記 (一) - 了解 startmaster.py

起動gFirefly 流程

加載gfirefly, master.py

1. 執行 startmaster.py -> 執行master.py
2. 由config.json 讀取數服務器結構
3. 加載了gfirefly, gtwisted, flask
4. 起動master server
5. GlobalObject() 中加入 json_config, root (PBroot), webroot (flask)
6. 起動日志系統
7. 監聽各動返回數據的端口 (webport, rootport)
8. 使用cmd 起動 node 服務器
9. 執行appmain.py (查看下一篇文章︰)

cmd 的內容如下︰

python appmain.py chatserver config.json
