# Configure incoming connections of a Public Cloud Databases for MySQL service
## 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](https://www.ovhcloud.com/de/public-cloud/) in your OVHcloud account
- A MySQL database running on your OVHcloud Public Cloud Databases ([this guide](/de/guides/public-cloud/databases/getting-started.md) can help you to meet this requirement)
***
### OVHcloud Control Panel Access
- **Direct link:** Public Cloud Projects
- **Navigation path:** Public Cloud > Select your project
***
## 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.
:::warning
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:
```sql
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 clicking on the button `Add user
`.
Enter a username then click `Create User
`.
:::info
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
:::warning
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.
Validate the changes by clicking the `Save changes
` button.
:::info
If you want to allow connections from the outside, you can enter the IP 0.0.0.0/0. Please use it carefully.
:::
#### Collect required information
Select the `Dashboard
` tab to find the required login credentials in the `Connection information`
section.
Select the `Databases
` tab to get the database name.
Select the `Users
` tab to get the username.
