Linux system installs mysql5.7 image and creates container

1 Pull the official mysql5.7 image

docker pull mysql:5.7

2. Create a mysql container

Create a mapping directory of mysql locally

mkdir -p /root/mysql/data /root/mysql/logs /root/mysql/conf

Create a *.cnf file in /root/mysql/conf (call it whatever)

touch my.cnf

Create a container, map data, logs, and configuration files to the machine

docker run -p 3306:3306 --name mysql -v /root/mysql/conf:/etc/mysql/conf.d -v /root/mysql/logs:/logs -v /root/mysql/data:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7

-d: run the container in the background

-p maps the port of the container to the port of the machine

-v mount host directory to container's directory

-e set parameters

3 Start the mysql container

docker start mysql

Check whether there are data files in the /root/mysql/data directory

ls
