通过docker-compose快速搭建数据库，并且修改相关字符集为utf8mb4

vi docker-compose.yml
version: ‘2‘
services:
mysql:
  image: mysql:5.7.22
#image: byh-registry:5000/mysql:v5.7.22
  restart: always
  container_name: mysql_zw
  volumes:
    - ./mysql:/var/lib/mysql
    - ./conf:/etc/mysql
    - /etc/localtime:/etc/localtime

  environment:
    - TZ=Asia/Shanghai
    - MYSQL_ROOT_PASSWORD=123456
  ports:
    - 13506:3306
  #network_mode: ‘host‘

#数据库删减版配置文件

vi ./conf/my.cnf

[mysql]
default-character-set = utf8mb4
[client]
default-character-set = utf8mb4
[mysqld]
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
datadir = /var/lib/mysql
symbolic-links=0
character-set-server = utf8mb4

#sql模块修改
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

#允许最大传输文件大小
max_allowed_packet = 1G
