pomelo原始碼分析 一

}

var pomelo = require('pomelo');

/** */
// route configures
// filter configures
});process.on('uncaughtexception', function(err) );

注意：在webstorm下除錯，可能因為工作目錄的設定原因會導致應用的執行路徑問題，導致無法讀取配置檔案，所以需要根據實際情況修改如下

var opt =

};

/**

* * @module
*//**
*//**
* initialize the server.
* *   - setup default configuration
* * @api private
*/  opts = opts || {};
this.loaded = ;
this.components = {};
this.settings = {};   // set，和get功能的容器
this.set('base', opts.base);  //設定伺服器的工作目錄
this.defaultconfiguration();  //根據配置檔案，載入master，monitor等伺服器
};

/**

* * @api private
*/  var args = utils.argsinfo(process.argv);
this.loadservers();  //載入伺服器配置資訊
this.loadconfig('master', this.getbase() + '/config/master.json'); //載入mater伺服器配置資訊
this.processargs(args); //根據啟動引數設定伺服器配置
this.configlogger();
};

utils.argsinfo(process.argv); 獲取系統啟動引數，我們不妨看看到底有哪些引數支援 

啟動game-server伺服器：>pomelo start [development | production] [--daemon]

/**

* setup enviroment.
* @api private
*/  this.set('env', args.env || process.env.node_env || 'development', true);
};

載入伺服器資訊，並且儲存在__servermap___記憶體下

/**

* load server info from configure file.
* * @api private
*/  this.loadconfig('servers', this.getbase() + '/config/servers.json');
var servers = this.get('servers');
var servermap = {}, slist, i, l, server;
for(var servertype in servers) ,,],
"chat":[,,
],"gate":[
]    },
"production":,,],
"chat":[,,
],"gate":[
]  }
}

工具函式，讀取json配置檔案，在這裡讀取的是master.json檔案

/**

* load configure json file to settings.
* * @param  key environment key
* @param  val environment value
* @return  for chaining, or the setting value
* */
var env = this.get('env');
val = require(val);
if (val[env]) 
this.set(key, val);
};

master.json

,

"production":
}

根據程序讀取配置好的引數，配置伺服器。

var servertype = args.servertype || 'master';

var serverid = args.serverid || this.get('master').id;

this.set('main', args.main, true);

this.set('servertype', servertype, true);

this.set('serverid', serverid, true);

if(servertype !== 'master') else

};專案的日誌配置

if(process.env.pomelo_logger !== 'off')

};log4js.json
