SQLAlchemy connect through specific network interface
To connect to a database through a specific network interface using SQLAlchemy, you can specify the interface's IP address as the host parameter when creating the engine object.
Here's an example of how to create an engine object with a specific IP address:
pythonfrom sqlalchemy import create_engine
db_host = '192.168.0.10'
db_name = 'mydb'
db_user = 'myuser'
db_pass = 'mypassword'
engine = create_engine(f'mysql+pymysql://{db_user}:{db_pass}@{db_host}/{db_name}')
In this example, the db_host
variable contains the IP address of the network interface you want to use to connect to the database. The create_engine()
function is used to create an engine object for connecting to the database. The mysql+pymysql
specifies the database type and driver to use, and the db_user
, db_pass
, and db_name
variables contain the login credentials and database name.
By default, SQLAlchemy will use the network interface with the default route for outgoing traffic. If you want to use a different interface, you can specify the interface's IP address as the host parameter, as shown in the example above.
Note that this approach assumes that the network interface you want to use is configured correctly and has the appropriate permissions to access the database. You may need to configure your network settings and firewall rules to allow traffic through the specific interface.
