今天利用docker容器创建mysql8.0的时候(window系统)，指定了本地宿主机器的一个目录为容器mysql的datadir目录，发现创建失败了。

创建命令：

$ docker run -d --name mysql81 -v /e/container/mysql/mysql81/datadir:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -p 33081:3306 mysql

错误提示：

$ docker logs mysql81

2019-01-26T03:05:42.832609Z 1 [ERROR] [MY-012981] [InnoDB] Cannot continue operation.

解决办法：

docker run -u 1000:50 -d --name mysql81 -v /e/container/mysql/mysql81/datadir:/var/lib/mysql -e MYSQL_ROOT_PASSWORD=123456 -p 33081:3306 mysql --innodb-use-native-aio=0

参数：

-u 表示运行实例的用户，这里的 1000:50 表示的是docker这个用户

–innodb-use-native-aio=0 为MySQL的参数，作用是启用异步操作功能，提高MySQL性能

注意：

上面使用了docker运行了mysql实例，则如果进入到容器内部进行一些其它需要高级权限的操作的话，如apt update则会提示权限不足的情况。
