[Bug]: Can not contact with database(MySQL, PostgreSQL and MariaSQL, what all of if giving)

[12dc32d]

Is there an existing issue for the same bug?

• I have checked the existing issues.

Branch name

Can't connect to MySQL server on '127.0.0.1' ([Errno 111] Connection refused)

Commit ID

none

Other environment information

Windows wsl CentOS7

Actual behavior

I can connect to MySQL, PostgreSQL, and MariaSQL normally in the terminal and other database operation software (I have tried all of them).
However, I cannot connect to the local database using the database name, user name, host, and password in the ragflow Agent.

I turned off the firewall and confirmed that all three databases are running in Task Manager and can be operated normally in the terminal and visualization tool.
The error is:
Can't connect to MySQL server on '127.0.0.1' ([Errno 111] Connection refused).

Of course, I also tried using "localhost" as the host, but the error message was:
Can't connect to MySQL server on 'localhost' ([Errno 111] Connection refused).

This is my input:
Database type
MariaSQL

Database
ragflow

User name
root

Host
127.0.0.1

Port
3306

Password

---

Expected behavior

Connect to the database after entering the correct parameters

Steps to reproduce

When creating a workflow in the agent, you cannot connect to any of the local databases MySQL, PostgreSQL, or MariaSQL when using a database connection.

Check conf/service_conf.yaml, make sure all the host in that configuration file can be accessible through the network that hosts RAGFlow.

Do you run RAGFlow by docker container or what?
If it is, 127.0.0.1 is a wrong IP for other services deployed on the same host.

Thank you very much for your reply, it is very useful to me. I have read many articles and blogs about how to use docker in the past, but I didn't use it correctly.
Is it possible to integrate the workflow (especially the agent) started by docker on the web page into a separate application? I packaged it directly on dockerhub but failed.
