一、下载mysql8镜像

docker pull mysql

二、创建mysql8配置文件

vi /etc/my.cnf #编辑MySQL配置文件

my.cnf文件内容

三、创建mysql容器

docker run -p 60306:3306 -e MYSQL_ROOT_PASSWORD=123 -v /etc/my.cnf:/etc/mysql/my.cnf:rw -v /etc/localtime:/etc/localtime:ro --name mysql8 --restart=always -dit mysql -p 60306:3306 #本机60306端口映射到容器3306端口 -e MYSQL_ROOT_PASSWORD=123 #设置MySQL的root用户密码 -v /etc/my.cnf:/etc/mysql/my.cnf:rw #本机的MySQL配置文件映射到容器的MySQL配置文件 -v /etc/localtime:/etc/localtime:ro #本机时间与数据库时间同步 --name mysql8 #设置容器别名 --restart=always #当重启Docker时会自动启动该容器 -dit mysql #后台运行并可控制台接入

四、进入mysql控制台

docker exec -it b6cfb244d0c0 bash #进入MySQL容器 mysql -uroot -p123 #进入MySQL控制台 ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456'; #修改root用户密码
