docker-compose部署Mysql8.0

docker-compose 部署mysql 8.x

编写docker-compose.yaml文件

version: '3.1'
services:
  db:
    image: mysql:8.0.20
    container_name: mysql
    restart: always
    environment:
      # 设置root密码
      MYSQL_ROOT_PASSWORD: Abcd1234
    command:
      --default-authentication-plugin=mysql_native_password
      --character-set-server=utf8mb4
      --collation-server=utf8mb4_general_ci
      --explicit_defaults_for_timestamp=true
      --lower_case_table_names=1
    ports:
      - 3306:3306
    volumes:
      - ./data/mysql:/var/lib/mysql # 挂载mysql数据卷
      - ./config/my.cnf:/etc/mysql/my.cnf # 挂载mysql my.cnf配置文件

创建文件 my.cnf

如果一开始没有这个文件可以从容器内部复制出来

# 启动一个容器
docker run --name mysql -itd mysql:2.0.20
# 复制容器内部my.cnf文件到宿主机的config文件夹下
docker cp mysql:/etc/mysql/my.cnf ./config/my.cnf

my.cnf
