创建启动容器
docker run --restart=always -d -v /home/app/mysql/conf.d/my.cnf:/etc/mysql/my.cnf -v /home/app/mysql/logs:/logs -v /home/app/mysql/data/mysql:/var/lib/mysql -p 3306:3306 --name mysql -e MYSQL_ROOT_PASSWORD=123456 mysql:8.0.18
参数解释
--restart=always -> 开机启动容器,容器异常自动重启
-d -> 以守护进程的方式启动容器
-v /home/app/mysql/conf.d/my.cnf:/etc/mysql/my.cnf -> 映射配置文件
-v /home/app/mysql/logs:/logs -> 映射日志
-v /home/app/mysql/data/mysql:/var/lib/mysql -> 映射数据
-p 3306:3306 -> 绑定宿主机端口
--name mysql -> 指定容器名称
-e MYSQL_ROOT_PASSWORD=123456 -> 写入配置root密码
最终结果
