Objective

Public Cloud Databases allow you to focus on building and deploying cloud applications while OVHcloud takes care of the database infrastructure and maintenance in operational conditions.

This guide explains how to configure your MySQL instance to accept incoming connections.

Requirements

  • A Public Cloud project in your OVHcloud account
  • A MySQL database running on your OVHcloud Public Cloud Databases (this guide can help you to meet this requirement)

OVHcloud Control Panel Access


Instructions

Configure your MySQL instance to accept incoming connections

Before making a connection, we need to verify that our MySQL instance is correctly configured.

Click on Databases in the left-hand navigation bar and select your MySQL instance.

Step 1: Verify your user roles and password

Select the Users tab. Verify that you have a user with sufficient rights and a configured password. If you don't remember the user's password, you can either create a new user or regenerate the password of an existing user.

Be careful! By doing so you will need to update all the places where you already use this user/password pair.

This first user avnadmin is pre-configured during the service installation and comes with the following grants:

GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, RELOAD, PROCESS, REFERENCES, INDEX, ALTER, SHOW DATABASES, CREATE TEMPORARY TABLES, LOCK TABLES, EXECUTE, REPLICATION SLAVE, REPLICATION CLIENT, CREATE VIEW, SHOW VIEW, CREATE ROUTINE, ALTER ROUTINE, CREATE USER, EVENT, TRIGGER ON *.* TO "avnadmin"@"%" WITH GRANT OPTION

GRANT REPLICATION_APPLIER,ROLE_ADMIN ON *.* TO "avnadmin"@"%" WITH GRANT OPTION

User table

You can add more users by clicking on the button Add user.

Add user

Enter a username then click Create User.

You can delete a user or regenerate a password via the ... button in the Users & Roles table.

Step 2: Authorise incoming connections from the MySQL client

For security reasons the default network configuration doesn't allow any incoming connections. It is thus critical you authorise the suitable IP addresses in order to successfully access your database.

Fill in the IP address or CIDR block to whitelist and click the + button.

Add an IP

Validate the changes by clicking the Save changes button.

Add an IP

If you want to allow connections from the outside, you can enter the IP 0.0.0.0/0. Please use it carefully.
