Create/Start/Configure MySQL container

Create a mysql container named mysql-8.0.27-container based on the image mysql:8.0.27, and set the root user passwordFor ******** (remember to map port 3306 to port 3306 of the host):

$ docker run--restart=always--privileged=true--name mysql-8.0.27-container-e MYSQL_ROOT_PASSWORD=********-p 3306:3306-dmysql:8.0.27

If you need to mount the data volume (/var/lib/mysql) and configuration file (/etc/mysql/conf.d) to the data of the host hard diskVolume (/home/muyao/mysql) and (/home/muyao/conf), you need to use -v to map the following parameters, only the data volume is mapped here.Complete command:

$ docker run --name mysql-8.0.27-container -e MYSQL_ROOT_PASSWORD=******** -v /home/muyao/mysql:/var/lib/mysql -p 3306:3306 -d mysql:8.0.27

Startup successful!

Enter the container and run the mysql command to enable remote permissions and refresh permissions:

$ docker exec -it mysql-8.0.27-container bash$ mysql -u root -p> grant all privileges on *.* to [email protected]'%' with grant option;> flush privileges;

Execute the above command.

Execution result.It can be seen that the host of root should become %, that is, all ips are allowed.

Connection Test

Use the db plugin NoSQL of vscode to test the connection, which is successful.(Stepping on the pit: The mapping of 3306 was not done at the beginning, resulting in no successful connection.)
