[英]Python Flask mongoengine/pymongo: Connection refused on port 27018 of mongo
The error is:错误是:
pymongo.errors.ServerSelectionTimeoutError: localhost:27017: [Errno 111] Connection refused, Timeout: 30s, Topology Description: <TopologyDescription id: 601833aec47f2f6e0a5ca109, topology_type: Single, servers: [<ServerDescription ('localhost', 27017) server_type: Unknown, rtt: None, error=AutoReconnect('localhost:27017: [Errno 111] Connection refused')>]>
I created an image with docker with port 27018 .我使用端口为27018的 docker 创建了一个图像。 Like this:
像这样:
docker run --name test -e MONGODB_DATABASE=ms-content-test -e MONGODB_USER=ms-content-test -e MONGODB_PASS=ms-content-test **-p 27018:27017** -d mongo
On my config.py file for tests, I created the connection, like this:在用于测试的 config.py 文件中,我创建了连接,如下所示:
class TestingConfig:
TESTING = True
DEBUG = True
# Database Test
DB = os.environ.get('DB', 'ms-content-test')
USERNAME = os.environ.get('USERNAME', 'ms-content-test')
PASSWORD = os.environ.get('PASSWORD', 'ms-content-test')
HOST = os.environ.get('HOST', 'localhost')
PORT = int(os.environ.get('PORT', 27018))
MONGO_URI = 'mongodb://{username}:{password}@{host}:{port}/{database}'.format(
username=USERNAME,
password=PASSWORD,
host=HOST,
port=PORT,
database=DB
)
Now, when I try to test the application, the port 27018 is not working.现在,当我尝试测试应用程序时,端口27018无法正常工作。 Using the port 27017 , works normally.
使用端口27017 ,可以正常工作。 On MONGO_URI, I have already tried to pass some arguments like
authSource="admin"
or using pymongo variables to connect, but nothing works.在 MONGO_URI 上,我已经尝试过传递一些 arguments 之类的
authSource="admin"
或使用 pymongo 变量进行连接,但没有任何效果。
Internally is like the Mongodb is always forcing use the 27017 port.内部就像 Mongodb 总是强制使用27017端口。 This is the lib of mongoengine: https://github.com/MongoEngine/mongoengine/blob/master/mongoengine/connection.py
这是mongoengine的库: https://github.com/MongoEngine/mongoengine/blob/master/mongoengine/connection.py
Your docker run
command is incorrect.您的
docker run
命令不正确。 The format of the -p
argument is -p CONTAINER_PORT:HOST_PORT
. -p
参数的格式是-p CONTAINER_PORT:HOST_PORT
。
Your -p 27018:27017
argument is redirecting all request from port 27017 on your development machine to port 27018 on your docker container.您的
-p 27018:27017
参数将所有请求从开发机器上的端口 27017 重定向到 docker 容器上的端口 27018。
If you were trying to publish a range of ports you would have to have individual -p
arguments for each of them.如果您尝试发布一系列端口,则必须为每个端口设置单独的
-p
arguments。
