# OR use url
$ sling conns set MYSQL url="mysql://myuser:mypass@host.ip:3306/mydatabase?tls=skip-verify"

Environment Variable

export MYSQL='mysql://myuser:mypass@host.ip:3306/mydatabase?tls=skip-verify'

Sling Env File YAML

See here to learn more about the sling env.yaml file.

connections:

    user: <user>
    port: <port>
    database: <database>
    schema: <schema>
    password: <password>

  MYSQL_URL:
    url: "mysql://myuser:mypass@host.ip:3306/mydatabase?tls=skip-verify"

Database user creation

To allow Sling to access your database, we need to create a user with the proper privileges. Please follow the steps below:

  1. First you’ll need to login as a user with CREATE USER and GRANT OPTION privileges. Create a user sling (or whatever you prefer) by running :

    CREATE USER 'sling'@'%' IDENTIFIED BY '<password>';
  2. If you are planning to load data into this connection, you need to grant the following privileges to that user so we can create tables in schema sling:

    CREATE SCHEMA sling;
    GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER, CREATE TEMPORARY TABLES, CREATE VIEW ON sling.* TO 'sling'@'%';
  3. If you are planning to extract data from this connection, you need to give permission to read the tables you'd like Sling to extract.

    -- To give read access to all tables in a specific schema
    GRANT SELECT ON <schema_name>.* TO  'sling'@'%';

If you are facing issues connecting, please reach out to us at support@slingdata.io, on discord or open a Github Issue here.
