What Should I Do If an Error Is Reported Indicating an Incorrect Username or Password During Link Creation but They Are Correct Indeed?

Symptom

During the creation of a MySQL link, an error is reported indicating an incorrect username or password, but they are correct indeed. With the same configuration, a data link can be successfully created on ROMA.

Fault Analysis

The MySQL database has a whitelist. Test the link from a MySQL client on another ECS that can communicate with the current ECS through the intranet.

Solution

The MySQL account is not authorized to use the CDM cluster. The MySQL database needs to authorize the IP address of the CDM cluster.
