Can MySQL listen to local connections?

One of the more common problems that users run into when trying to set up a remote MySQL database is that their MySQL instance is only configured to listen for local connections. This is MySQL’s default setting, but it won’t work for a remote database setup since MySQL must be able to listen for an external IP address where the server can be reached.

Can you access a database server remotely?

Can a website and database be hosted on the same machine?

Many websites and applications start off with their web server and database backend hosted on the same machine. With time, though, a setup like this can become cumbersome and difficult to scale. A common solution is to separate these functions by setting up a remote database, allowing the server and database to grow at their own pace on their own machines.

Many monitoring tools, like Portainer, need access to the Docker API endpoint to monitor details like networks, running containers, etc. Normally to add a server to the endpoint list, you'd have to deploy a Portainer agent on the server first and bind some port from the container to the host.
