MySQL is a fast, multi-threaded, multi-user, and robust SQL database server. It is intended for mission-critical, heavy-load production systems and mass-deployed software.


Raspberry Pi computer supports 64-bit instructions since version 3 release, but operation system Raspberry Pi OS (previously called Raspbian) is 32-bit system. To get real 64-bit computer you should install 64-bit Ubuntu or now there is opportunity to use Raspberry Pi 64-bit beta version. Run an example application and confirm your Pi 3 docker instances are accessible from anywhere in the network. [email protected]: $ docker run -d -p 8081:8081 resin/rpi-google-coder. Once the container is pulled and started, confirm that it's running. [email protected]: $ docker ps. CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 3a163325ba16.

  • Hi, in this post we will install Docker on Raspberry Pi and Portainer to manage our container using any web browser from another computer. Docker ables to us to install/uninstall tons of softwares with a simple command.
  • Part 1: Getting the most from Raspberry Pi 4, whose concrete scope is to integrate a M.2 SSD physical disk with a 64 bits operating system running the Raspberry Pi, that provides 4Gb RAM. Part 2: Installing Docker in Raspberry Pi 4, that focuses in development methodology and shows the process to prepare a Docker ready development environment.

To install MySQL, run the following command from a terminal prompt:

Once the installation is complete, the MySQL server should be started automatically. You can quickly check its current status via systemd:

The network status of the MySQL service can also be checked by running the ss command at the terminal prompt:

When you run this command, you should see something similar to the following:

If the server is not running correctly, you can type the following command to start it:

A good starting point for troubleshooting problems is the systemd journal, which can be accessed at the terminal prompt with this command:


You can edit the files in /etc/mysql/ to configure the basic settings – log file, port number, etc. For example, to configure MySQL to listen for connections from network hosts, in the file /etc/mysql/mysql.conf.d/mysqld.cnf, change the bind-address directive to the server’s IP address:


Replace with the appropriate address, which can be determined via ip address show.

After making a configuration change, the MySQL daemon will need to be restarted:

Database Engines

Whilst the default configuration of MySQL provided by the Ubuntu packages is perfectly functional and performs well there are things you may wish to consider before you proceed.

MySQL is designed to allow data to be stored in different ways. These methods are referred to as either database or storage engines. There are two main engines that you’ll be interested in: InnoDB and MyISAM. Storage engines are transparent to the end user. MySQL will handle things differently under the surface, but regardless of which storage engine is in use, you will interact with the database in the same way.

Each engine has its own advantages and disadvantages.

While it is possible, and may be advantageous to mix and match database engines on a table level, doing so reduces the effectiveness of the performance tuning you can do as you’ll be splitting the resources between two engines instead of dedicating them to one.

  • MyISAM is the older of the two. It can be faster than InnoDB under certain circumstances and favours a read only workload. Some web applications have been tuned around MyISAM (though that’s not to imply that they will slow under InnoDB). MyISAM also supports the FULLTEXT data type, which allows very fast searches of large quantities of text data. However MyISAM is only capable of locking an entire table for writing. This means only one process can update a table at a time. As any application that uses the table scales this may prove to be a hindrance. It also lacks journaling, which makes it harder for data to be recovered after a crash. The following link provides some points for consideration about using MyISAM on a production database.

  • InnoDB is a more modern database engine, designed to be ACID compliant which guarantees database transactions are processed reliably. Write locking can occur on a row level basis within a table. That means multiple updates can occur on a single table simultaneously. Data caching is also handled in memory within the database engine, allowing caching on a more efficient row level basis rather than file block. To meet ACID compliance all transactions are journaled independently of the main tables. This allows for much more reliable data recovery as data consistency can be checked.

As of MySQL 5.5 InnoDB is the default engine, and is highly recommended over MyISAM unless you have specific need for features unique to the engine.

Advanced configuration

Creating a tuned configuration

There are a number of parameters that can be adjusted within MySQL’s configuration files that will allow you to improve the performance of the server over time.

Many of the parameters can be adjusted with the existing database, however some may affect the data layout and thus need more care to apply.

First, if you have existing data, you will need to carry out a mysqldump and reload:

This will then prompt you for the root password before creating a copy of the data. It is advisable to make sure there are no other users or processes using the database whilst this takes place. Depending on how much data you’ve got in your database, this may take a while. You won’t see anything on the screen during this process.

Once the dump has been completed, shut down MySQL:

It’s also a good idea to backup the original configuration:

Next, make any desired configuration changes.

Then delete and re-initialise the database space and make sure ownership is correct before restarting MySQL:

The final step is re-importation of your data by piping your SQL commands to the database.

For large data imports, the ‘Pipe Viewer’ utility can be useful to track import progress. Ignore any ETA times produced by pv, they’re based on the average time taken to handle each row of the file, but the speed of inserting can vary wildly from row to row with mysqldumps:

Once that is complete all is good to go!


This is not necessary for all my.cnf changes. Most of the variables you may wish to change to improve performance are adjustable even whilst the server is running. As with anything, make sure to have a good backup copy of config files and data before making changes.

MySQL Tuner

MySQL Tuner connects to a running MySQL instance and offer configuration suggestions to optimize the database for your workload. The longer the server has been running, the better the advice mysqltuner can provide. In a production environment, consider waiting for at least 24 hours before running the tool. You can install mysqltuner from the Ubuntu repositories:

Then once its been installed, run:

and wait for its final report. The top section provides general information about the database server, and the bottom section provides tuning suggestions to alter in your my.cnf. Most of these can be altered live on the server without restarting; look through the official MySQL documentation (link in Resources section) for the relevant variables to change in production. The following example is part of a report from a production database showing potential benefits from increasing the query cache:

It goes without saying that performance optimization strategies vary from application to application. So for example, what works best for Wordpress might not be the best for Drupal or Joomla. Performance can be dependent on the types of queries, use of indexes, how efficient the database design is and so on. You may find it useful to spend some time searching for database tuning tips based on what applications you’re using. Once you’ve reached the point of diminishing returns from database configuration adjustments, look to the application itself for improvements, or invest in more powerful hardware and/or scaling up the database environment.

I will continue to refer to the OS as Raspbian because (1) that’s what they named it when first released and (2) it still says that on the operating sytem. Therefore the name has stuck and still sticks.

Here are the steps to install Docker and the Portainer container that provides your Docker installation with a simple, web-based dashboard.

Update 64-bit Raspbian:

Install Docker from the Docker website:

Add the pi account to the docker user group so that you can execute docker commands without sudo:

Log back in and test Docker by installing and running the following container.

The container will run and tell you it was successful with additional information about Docker and its OS.

To be honest, I haven’t tried the recommendation about running the Ubuntu container, as I don’t know if it there is an ARM Ubuntu container (there is ARM Ubuntu, however) and if it will select the right container if there is such a container.

Install the next two containers. The first is a very simple http container.

Navigate to http://localhost with Chromium and you’ll see this:
Now add the dashboard container that implements Portainer for ARM.


Navigate to http://localhost:9000/ and create an admin password for the admin account. Once that is accomplished, you’ll see something very similar to this:

You’ll note that only two containers are listed, not three. That’s because earlier I removed the “Hello World” container. Here’s a detailed listing of the containers.

To manage any of the containers, you select that container’s checkbox. That enables all of the possible action buttons at the top of the page. Finally, here’s a check of the entire system.


The engine overview is a cleaner view of what you can get from the command line. It’s also a validation that the dashboard container is seeing everything it’s supposed to see.

If you want any container to restart after a re-boot, then you need to modify the container’s restart policy. Otherwise, on reboot, no containers are running. For example

where he container ID can be found with a docker ps from the command line. You can set restart to always from the command line with the docker run command as well.

It’s a limitation to this application I don’t like. I’m looking for something more comprehensive, or else, (shudder) I fork the application and “fix” it myself.
