In order to do the backup, we need to find the local directory on the host where the data exists as well as the internal IP that the container is using so the xtrabackup container can reach it.

#Starting mysql database server mysqld docker mysql password

Mysql: Using a password on the command line interface can be insecure. ~]# docker exec -it mysql1 mysql -u root -ppassword -e 'Select * from dockertest.t1' ~]# docker psĬONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMESĭ5d980ee01d5 mysql/mysql-server:5.7.22 '/entrypoint.sh my.' 19 hours ago Up 2 minutes (healthy) 0.0.0.0:3306->3306/tcp, 33060/tcp mysql1 In short, you would get a simple container like this if you were to run ‘docker run -p 3307:3306 –name=mysql1 -e MYSQL_ROOT_PASSWORD=password -d mysql/mysql-server:5.7.22’. It should also be noted that the container is leveraging Docker internal networking via the Docker interface and did not have a volume mount specified for the data directory when it was created with Docker run, thus forcing Docker to create one for us in a location of its choosing. You’ll see I have a container instance running 5.7.22 that contains a small set of sample data and has an exposed and mapped port. So let’s get started and see how this works.įirst, let’s have a look at the instance that we want to back up.

This can be extra handy for you if you’re a Windows user, as Docker is the only way to get xtrabackup running in Windows currently. Additionally, we’re trying to think with containers here, so I wanted to make sure that not only would I be taking a backup of the Docker container MySQL instance, but I would do it with another Docker container running xtrabackup.

#Starting mysql database server mysqld docker mysql how to

There is a fair bit of documentation on how to handle this logically (mysqldump / mydumper) as this is a simple task to perform as long as you can connect to the database instance, so I wanted to approach physical backups using the very common xtrabackup tool. I would venture to say that backups are probably among the most important tasks we take on with database administration, so it’s important to know how to do this for Docker MySQL instances. Part of that was exploring common administrative tasks.

If you use Django, here is what you need to put in the settings.pyĭATABASES = įrom now, you can connect to your MySQL anytime you want.In a previous post I had mentioned that I was doing a bit of digging into Docker in order to get a better grasp of the technology.

Create user and database for the connectionĬREATE DATABASE databaseName CREATE USER IDENTIFIED BY '123456' GRANT ALL PRIVILEGES ON databaseName.* TO FLUSH PRIVILEGES QUIT.

# Through host mysql -host 127.0.0.1 -P 3306 -protocol=tcp -u root -p # Through container docker exec -ti mysql-server bash mysql -u root -p

You can access the MySQL through your host.mysqld -default-authentication-plugin=mysql_native_password It is because the newer version of MySQL uses caching_sha2_password instead of mysql_native_password. Then you can add the parameter below when running the container. Unable to load authentication plugin 'caching_sha2_password'. If you cannot connect to MySQL from another docker and got this error:.

p 12345:3306 # This is one method to check for the port on MAC OS netstat -vanp tcp | grep 3306 If yes, you can change the port to a different one.

Please check if there other application that listens on port 3306 on your host machine.

Here is the command: docker run -d -p 3306:3306 -name=mysql-server -env='MYSQL_ROOT_PASSWORD=123456' mysql # This runs on a detached mode # Open port 3306:3306 # Name of the server: mysql-server # root password: 123456 # Container is created from mysql image The host can communicate with the database inside the container. So the Django Rest API locates on my host machine - I will move it to a container shortly. It just happens that I want to create a MySQL server for my Django Rest API.
