.│ .env│ docker-compose.yml│└─mysql ├─config │ my.cnf │ └─data

mysql directory data for the data directory, mysql data table, binary log files here. The env file contains variables that can be referenced in the docker-compose.yml file as ${variable_name}.

Of course, you can also put mysql directory to other places, here figure a convenient, directly placed in the yml file peer directory.

.env file

MYSQL_ROOT_PASSWORD=rootMYSQL_ROOT_HOST=%MYSQL_DIR=./ mysql

MySQL configuration file my.cnf

[mysqld]character-set-server=utf8mb4default-time-zone='+8:00'innodb_rollback_on_timeout='ON'max_connections=500innodb_lock_wait_timeout=500

This file can be omitted if the default configuration is used.

docker-compose.yml

version: '3'services: mysql-db: container_name: mysql-docker #Specify the name of the container image: mysql:8.0 #Specify mirror and version ports: - "3306:3306" environment: MYSQL_ROOT_PASSWORD: ${MYSQL_ROOT_PASSWORD} MYSQL_ROOT_HOST: ${MYSQL_ROOT_HOST} volumes: - "${MYSQL_DIR}/data:/var/lib/mysql" #Mount data directory- "${MYSQL_DIR}/config:/etc/mysql/conf.d" #Mount configuration file directory

Environment variable

MYSQL_ROOT_PASSWORD: This unexplained, root password. MYSQL_USER, MYSQL_PASSWORD: These two variables are optional and create a new user with superuser privileges on the database specified by the MYSQL_DATABASE variable. MYSQL_DATABASE: Specifies a database to be created at container startup. MYSQL_ALLOW_EMPTY_PASSWORD: Set to yes to allow root user passwords to be blank. MYSQL_RANDOM_ROOT_PASSWORD: Set to yes to generate a random password for root at container startup, and the password appears in the standard output stream (GENERATED ROOT PASSWORD: ...). MYSQL_ONETIME_PASSWORD: Literally means one-time password, set for root user, password must be changed after first login (only supports version 5.6 and above).

run containers

Execute in docker-compose.yml directory:

> docker-compose up

If you want to run in the background, use docker-compose up -d.

Stop container:

> docker-compose down

If running foreground, use Ctrl + C to stop. Both methods delete containers after stopping, and the next time you start, you must use the up command.

Stop without deleting containers:

> docker-compose stop

After stopping with stop, start again with start command.
