# ETL: Connecting to MySQL

> Connect MySQL databases to Integrate.io ETL for reading and writing data. Configure user permissions, firewall rules, and connection settings.

* Create a user and grant it minimum permissions required for Integrate.io ETL to read or write data from the database.
* Allow access from [Integrate.io ETL's IP addresses](/etl/integrateio-etls-ip-list/) to your MySQL database port (Refer to [this](/etl/allowing-integrateio-etl-access-to-my-server-behind-a-firewall/) article if you'd prefer to create an SSH tunnel or reverse SSH tunnel.)
