Question

我正在尝试连接到mongoDB，但似乎无法联系到主机。

在mongoshell和pymongo中会出现此问题。在shell上我使用

mongo --ssl --sslAllowInvalidCertificates host:port/db -u user -p pass --sslCAFile ca.pem

我收到错误信息。

MongoDB shell version: 3.2.9
connecting to: host:port/db
2016-09-30T13:41:57.268-0300 W NETWORK  [thread1] Failed to connect to host_ip:port after 5000 milliseconds, giving up.
2016-09-30T13:41:57.323-0300 E QUERY    [thread1] Error: couldn't connect to server host:port, connection attempt failed :
connect@src/mongo/shell/mongo.js:231:14
@(connect):1:6

exception: connect failed

在pymongo上，我用下面的代码连接

Config = configparser.ConfigParser()
Config.read('configurations.cfg')
mongo_conf = Config['mongoDB_test']

connect = "mongodb://%s:%s@%s:%s/%s?ssl=true" \
    %(mongo_conf['user'],mongo_conf['pass'],mongo_conf['host'],mongo_conf['port'],mongo_conf['database'])
client = MongoClient(connect,ssl_ca_certs=mongo_conf['cert'])
db = client[mongo_conf['database']]

当我跑步时，我得到了这个

Traceback (most recent call last):
  File "test.py", line 24, in <module>
    db.test.insert_one(data)
  File "/home/jmpf13/repos/laura/dev_env/lib/python3.5/site-packages/pymongo/collection.py", line 627, in insert_one

我刚刚连接到mongoDB实例，我使用mongo shell将其部署到bluemix，其语法与您使用的类似，并且工作正常。

您的部署可能存在问题。在bluemix ui中，当您打开mongo服务时，“状态”指示器是否显示为绿色？

我要做的另一件事是尝试验证该端口上是否可以访问主机。例如，使用tcping之类的东西： 1000101

或者，如果在紧要关头，telnet到端口： tcping <host> <port> 对于后者，你会得到类似的东西：

telnet <host> <port>

如果其中任何一项失败，我会确保您的任何内容都无法阻止流量，然后在部署未正确配置或出现问题时伸出援助支持。

无法连接到bluemix上的compose.io mongoDB
