Launch your Amazon RDS Dashboard.\n\n2. In the **Navigation Drawer** , click **Parameter Groups**.\n\n3. Click **Create Parameter Group** . The **Create Parameter Group** page appears.\n\n4. Use the following table to populate the fields of this page:\n\n5. Click **Create**.\n\n6. Select the checkbox to the left of your newly created parameter group.\n\n7. Under **Parameter group actions** , click **Edit**.\n\n8. Set the following parameter values:\n\n - For **GTID-based** replication:\n\n - For **binlog-based** replication:\n\n9. Click **Save Changes**.\n\nAssign the parameter group to the database instance\n---------------------------------------------------\n\n1. Launch your Amazon RDS Dashboard.\n\n2. In the **Navigation Drawer** , click **Databases**, and then select your database instance.\n\n3. From the **Instance Actions** menu, select **Modify** . The **Modify DB Instance** dialog appears.\n\n4. In the **Additional configuration** section, select the database cluster parameter group that you [created](#create-a-parameter-group-aurora).\n\n5. Set the **Backup retention period** to **7 days**.\n\n6. Click **Continue**.\n\n7. In the **Scheduling of Modifications** pane, select the **Apply immediately** option.\n\nSet the binary log retention period\n-----------------------------------\n\n1. Enter the following MySQL command:\n\n ```sql\n call mysql.rds_set_configuration('binlog retention hours', 168);\n ```\n | You're entering this command because you want to ensure proper replication by configuring your system to retain binary logs for a minimum of 7 days (or 168 hours).\n2. Restart your MySQL server so that the changes you made can take effect.\n\nCreate a Datastream user\n------------------------\n\n1. Create a Datastream user:\n\n ```sql\n CREATE USER 'datastream'@'%' IDENTIFIED BY '\u003cvar translate=\"no\"\u003eYOUR_PASSWORD\u003c/var\u003e';\n ```\n2. Grant the following privileges to them:\n\n ```sql\n GRANT REPLICATION SLAVE, SELECT, REPLICATION CLIENT ON *.* TO 'datastream'@'%';\n GRANT EXECUTE ON PROCEDURE mysql.rds_show_configuration TO 'datastream'@'%';\n FLUSH PRIVILEGES;\n ```\n\nWhat's next\n-----------\n\n- Learn more about how Datastream works with [MySQL sources](/datastream/docs/sources-mysql)."]]
