Question

我正在运行一个python脚本，将文档添加到远程mongodb数据库的集合中。该文件如下：

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()

当我运行这个脚本时，我有一些有趣的行为。在服务器日志中，似乎接受连接，运行查询，然后关闭连接。

# 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

然而，这是我从python脚本得到的：

一些有用的信息：远程服务器是在OpenVZ上运行的VPS。我知道有与count（）和迭代器相关的兼容性问题，但我（假设）通过使用--smallfiles选项修复它们，并将我的nssize限制为100.我的防火墙两侧都完全打开。

我还注意到，在错误中，即使我指定了不同的IP地址，autoreconnect也会尝试连接到localhost。

Answer 1

您需要传递IP - conn = Connection(ip)

连接似乎在服务器端接受，但在我的python脚本中似乎被拒绝
