1、拉取mysql5.7镜像

耐心等待

docker pull mysql:5.7

2、宿主机中搭建mysql工作目录

mkdir -p /data/mysql/conf
mkdir -p /data/mysql/mysqldata
touch /data/mysql/conf/my.cnf

3、编写docker-compose.yml文件

cd /data/mysql
vim docker-compose.yml

写入以下内容

version: '3'
services:
  #服务名称,自定义
  mysql:
    build:
      context: .
    #镜像名称
    image: mysql:5.7
    #容器名称,自定义
    container_name: mysql
    restart: always
    #宿主机和容器端口映射
    ports:
      - '3306:3306'
    #宿主机和容器目录映射
    volumes:
      - /data/mysql/conf/my.cnf:/etc/my.cnf
      - /data/mysql/mysqldata:/var/lib/mysql
    command: [
          'mysqld',
          '--character-set-server=utf8mb4',
          '--collation-server=utf8mb4_unicode_ci',
        ]
    environment:
      #密码
      MYSQL_ROOT_PASSWORD: root
