猫鼬超时不适用

Question

我想增加mongoose的连接超时，因为我的MongoDB需要一些时间来启动。

// I have also tried
// var mongooseOptions = { replset: { socketOptions: { connectTimeoutMS : config.mongodb.dbTimeout }}};
var mongooseOptions = { server: { socketOptions: { connectTimeoutMS: config.mongodb.dbTimeout }}};
logger.info('Establishing connection to MongoDB... (Timeout is ' + config.mongodb.dbTimeout + ')');
mongoose.connect(config.mongodb.uri, mongooseOptions, function (error) {
    if (error) {
        logger.error('Connection to MongoDB failed: ' + error);
        return;
    }
    ...

但是没有应用超时，它立即失败：

2015-04-24T10:43:10.156Z - info: Establishing connection to MongoDB... (Timeout is 300000)
2015-04-24T10:43:10.275Z - error: Connection to MongoDB failed: MongoError: connect ECONNREFUSED

编辑：我正在使用Mongoose 4.0.1
