How to solve the mysql module not found issue?

1. docker container prune -f # clean up exited containers
2. docker run --name lina -p 3306:3306 -e MYSQL_ROOT_PASSWORD=lina -d mysql # set username(root) password:lina, 3306:3306 used as communication docker machine and your host machine, 3306:3306 mysql by default TCP port.
3. docker ps # verify if the docker container is running.
4. docker exec -it fa9 /bin/bash # -i is interactive -t means console, 'fa9' is from docker ps, you must lookup this in docker ps first, fa9 is a prefix of the docker container ID you will enter the docker container after step 4, it appears you loggin another machine.
5. mysql --user root --database mysql --password # use mysql in the container to logon my sql server in the container
