What is the default authentication plugin for MySQL?

What is a MySQL guide?

This guide is intended to serve as a troubleshooting resource and starting point as you diagnose your MySQL setup. We’ll go over some of the issues that many MySQL users encounter and provide guidance for troubleshooting specific problems. We will also include links to DigitalOcean tutorials and the official MySQL documentation that may be useful in certain cases.

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. To enable this, open up your mysqld.cnf file:

Can you access a database server remotely?

If you only plan to access the database server from one specific machine, you can grant that machine exclusive permission to connect to the database remotely with the following command. Make sure to replace remote_IP_address with the actual IP address of the machine you plan to connect with:

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.

Can you connect to MySQL database from IP address?

Alternatively, you can allow connections to your MySQL database from any IP address with the following command: Warning: This command will enable anyone to access your MySQL database. Do not run it if your database holds any sensitive data. Following this, try accessing your database remotely from another machine:

How to confirm a docker command?

To confirm the above statement, run any docker command at the end of this section (while testing) with the -l debug flag. This will print the exact command being executed on your local machine.

What is a docker command?

The docker command is nothing but the client application. The client and the daemon communicate via the docker API over a traditional Unix socket that you can find at /run/docker.sock or /var/run/docker.sock. The client asks the daemon to do something, or retrieve information, and the daemon does just that.

What does SSH do to a remote host?

When using the SSH protocol for remote docker access what happens is that the docker client actually runs an ssh command on the local host, with a hidden docker command (docker system dial-stdio) on the remote host, that establishes a connection to the remote's dockerd endpoint which is almost always /var/run/docker.sock, and forward the connection to the commands stdio.

What flag do you use to run a docker?

Alternatively, you can also use the -H flag like I've done here with the docker command

How to copy a public key to a remote server?

Use ssh-copy-id user@ip command to copy over the public key to the remote server.

Is SSH secure on Docker?

Friends at docker have already considered this. Using SSH for the in-between protocol, it is as secure as your SSH sessions are. More on this in later section of this tutorial.

Can Portainer be remotely accessed?

All can be done remotely. 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.
