Administering the MySQL server

WARNING Whether hosted via Docker or directly on a machine, the MySQL server needs to be administered properly. Please refer to an appropriate reference to administer the server safely and efficiently.

How to use

Using docker-compose

The simplest and the recommended way to configure and run a MySQL server with Docker is to use the Docker compose. Once you have docker and docker-compose installed on your system (the one on which you'd want to run the MySQL server), copy this docker-compose.yml to a folder, and run docker-compose up -d to start the MySQL server. Here is a series of commands to run in the terminal to achieve this:

$ mkdir mysql-docker
$ cd mysql-docker
$ wget
$ sudo docker-compose up -d

This will start the MySQL server mapped to localhost's port 3306, and any MySQL data will be stored in the direction ./data, on if you followed the above instructions, mysql-docker/data directory.

By default the database sets up user root with password simple (refer to below on how to change this at the startup). You can access your locally running MySQL server using mysql client. On Ubuntu system, you can obtain this by installing apt package mysql-client as follows:

$ sudo apt-get install mysql-client

Once mysql client is installed, you can access the running server:

$ mysql -h -u root -p
Enter password: [type in your password here: default is "simple"]

Read on to find out the details about the content of the docker-compose.yml and how you can customize it to fit your needs.

What's in docker-compose.yml?

The content of the docker-compose.yml is rather simple:

version: '2'
    image: datajoint/mysql
      - "3306:3306"
      - MYSQL_ROOT_PASSWORD=simple
      - ./data:/var/lib/mysql

Let's step through the parts you might want to customize. The line


configures the default password. If you would like to use something else, you can modify this prior to starting your server with docker-compose up.

The lines:

  - ./data:/var/lib/mysql

maps the local directory ./data to the /var/lib/mysql inside the container where MySQL stores all of its data by default.

WARNING: If you decide map volume /var/lib/mysql (like in the example), then settings for your MySQL server will persist across separate Docker mysql instances. In particular, this means that the MYSQL_ROOT_PASSWORD setting will be used only when the very first mysql Docker container is created. To change the root password on an alredy created mysql Docker instance, access the database via mysql client as root and run:

$ mysql -h -u root -p
Enter password: [type in your old password]

mysql > SET PASSWORD FOR root = PASSWORD('your_new_password');

replacing the 'your_new_password' with your new desired password surrounded by quotes (').
