What if I failed to log in to the CVM database? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

There may be many reasons for the failure to log in to the CVM database. For example, there may be problems on the database server, which can be detected by following the steps below.

1. The connection mode is incorrect

Check the connection mode. The CVM and the database instance must be in the same virtual private cloud and can only be connected through the CVM.

two。 Full number of connections

Check whether the number of connections, CPU utilization and other indicators are normal through the resource monitoring feature of the database service. If the upper limit is reached, you need to restart the database, disconnect the instance, or upgrade the database specification.

3. Instance status exception

Such as restart stuck, database system failure, instance is locked and so on. Try to restart the feature. If you can't solve the problem, you can contact the service provider for after-sales technical support.

If the database failure is caused by a client problem, you can check it from the following aspects.

1. Security policy of the server

For the Windows platform, check that Windows's security policy opens the database port. For Linux platforms, you can use iptables to check the release of firewalls and ports.

3. Application configuration error

The common ones are misspelling of connection address, misconfiguration of port parameters and misconfiguration of connection parameters of JDBC.

3. Wrong user name or password

If an error similar to the following occurs when connecting to the database, check whether the user name or password of the CVM is correct.

This is the answer to how to solve the problem of failed login to the CVM database. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
