連接似乎接受服務器端，但似乎被拒絕在我的python腳本

Question

我有一個python腳本我正在運行將文檔添加到遠程MongoDB數據庫的集合。該文件如下：

from pymongo import Connection 
ip = 'x.x.x.x' #edited out 

conn = Connection() 
db = conn['netmon'] 

users = db.users 
print 'number of users: ' + str(users.count()) 
if users.count() == 0: 
    print 'Please create a new account.' 
    t_user = raw_input('Username:') 
    users.insert({'username':unicode(t_user)}) 
conn.close() 

當我運行這個腳本時，我有一些有趣的行爲。在服務器日誌中，似乎連接被接受，查詢運行，然後關閉連接。

# Mongodb logs 
14:27:18 [initandlisten] connection accepted from 108.93.46.75:39558 #1 
14:27:18 [conn1] run command admin.$cmd { ismaster: 1 } 
14:27:18 [conn1] command admin.$cmd command: { ismaster: 1 } ntoreturn:1 reslen:71 0ms 
14:27:18 [conn1] run command netmon.$cmd { count: "users", fields: null, query: {} } 
14:27:18 [conn1] Accessing: netmon for the first time 
14:27:18 [conn1] command netmon.$cmd command: { count: "users", fields: null, query: {} } ntoreturn:1 reslen:58 10ms 
14:27:18 [conn1] end connection 108.93.46.75:39558 

但是，這是我從python腳本得到：

一些有用的信息： 遠程服務器上運行OpenVZ的車輛定位系統。我知道有與count（）和迭代器相關的兼容性問題，但我（假設）通過使用--smallfiles選項修復了它們，並將我的nssize限制爲100.我的防火牆在兩端都完全打開。

我也注意到，在錯誤，autoreconnect嘗試連接到本地主機，即使我指定了不同的IP地址。

Answer 1

你需要通過IP - conn = Connection(ip)
