找不到我的MongoDB存储文件的位置

Question

这个问题我大概花了一整天的时间。我找不到我的MongoDB存储数据的位置。它不在user/data/db中。我运行了ps-xa | grep mongod，它不在列出的任何目录中。当我启动mongodb并执行show dbs时，我得到一个空数据库的列表。不知道硬盘在哪里。在这一点上，我不知道发生了什么。我正在运行的代码来自另一个网站，并且正在运行。它显示元素被插入到数据库中。我尝试了我所知道的一切，但没有任何效果。代码如下：

auth1 = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth1.set_access_token(access_token, access_token_secret)

class StreamListener(tweepy.StreamListener):
    def on_status(self, tweet):
        print tweet.text

    def on_error(self, status_code):
        print 'Error: ' + repr(status_code)
        return False

    def on_data(self, data):
        print 'Ok! Inserting Data.'
        from pymongo import MongoClient
        client = MongoClient()
        client = MongoClient('localhost', 27017)
        db = client.test
        test_id = db.twittertest.insert(json.loads(data))

l = StreamListener()
streamer = tweepy.Stream(auth=auth1, listener=l)
streamer.sample()

根据您使用的*ix，考虑尝试lsof-p或fuser。在

$ sudo lsof -p $$
