创建mysql 映射文件

my.cfg如下

[client]
default-character-set=utf8mb4[mysql]
default-character-set=utf8mb4[mysqld]
#服务端口号 默认3306
port=3306datadir = /usr/local/docker/mysql/datainit_connect='SET NAMES utf8mb4'
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci# 最大连接数
max_connections=200# 连接失败的最大次数。防止有人从该主机试图攻击数据库系统
max_connect_errors=20# 创建新表时将使用的默认存储引擎
default-storage-engine=INNODB

启动mysql容器

-e MYSQL_ROOT_PASSWORD=root123456 指定数据库密码

docker run -p 3306:3306 --name mysql --privileged=true -v /usr/local/docker/mysql/log:/var/log/mysql -v /usr/local/docker/mysql/data:/var/lib/mysql -v /usr/local/docker/mysql/conf:/etc/mysql/conf.d -e MYSQL_ROOT_PASSWORD=root123456 -itd 镜像id

进入容器

进入容器执行刷新权限等sql

-- 修改访问主机以及密码
ALTER USER 'root'@'%' IDENTIFIED BY 'root123456';-- 刷新权限
FLUSH PRIVILEGES;
