Learn how to configure your MySQL instance to accept incoming connections.
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.
Requirements
- A Public Cloud project in your OVHcloud account
- Access to the OVHcloud Control Panel
- A MySQL database running on your OVHcloud Cloud Databases (this guide can help you to meet this requirement)
Instructions
Configure your MySQL instance to accept incoming connections
Before establishing a connection, we must verify that our MySQL instance is properly configured.
Log in to your OVHcloud Control Panel and select your MySQL instance via the Public Cloud and Databases menus.
Step 1: Verify your user roles and password
Select the Users tab. Verify that you have a user 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.
NOTE: 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
You can add more users by selecting the Users tab and clicking the + Add user button.
Enter a username, then click Create User →.
You can delete a user or regenerate a password via the more options ... button in the Users & Roles table.
Step 2: Authorize incoming connections from the MySQL client
NOTE: For security reasons, the default network configuration doesn't allow any incoming connections. It is thus critical that you authorize suitable IP addresses to successfully access your database.
In this step, select the Configuration tab. IP addresses must be authorized here before they can connect to your database.
Enter an IP and a description, then click the "add" + button.
Click the Save changes button when you have added all the IPs you wish to authorize.
You can edit and retract database access via the more options ... button in the IP table.
If you want to allow connections from the outside, you can enter the IP 0.0.0.0/0. Please use it carefully.
