Create a MySQL container in Docker and establish connections with other containers . And implement the persistent preservation of data .

• pull mysql images :

    docker pull mysql:5.5.60
  

  or you can simply run

    ./build-image.sh
  

• in this project , we use ./mysql/conf and ./mysql/data to save data from docker mysql .

  so , plz rm the content in data , and do not remove the mysqld.conf file in ./mysql/conf

• start mysql :

    docker-compose up -d mysql     
  

• stop mysql :

    docker-compose down
