创建并启动容器

docker run -p 3306:3306 --name mysql \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root(改为你想要设置的mysql密码) \
-d mysql:8.0.16

解决办法

需要加上-v /mydata/mysql/mysql-files:/var/lib/mysql-files ，用来对/var/lib/mysql-files 和宿主机的目录做映射

1.先停止容器

docker stop mysql(这里是容器名，或者容器id)

2.删除容器

docker rm mysql

3. 重新执行创建并启动容器的命令（）

docker run -p 3306:3306 --name mysql \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/etc/mysql \
-v /mydata/mysql/mysql-files:/var/lib/mysql-files \
-e MYSQL_ROOT_PASSWORD=root(改为你想要设置的mysql密码) \
-d mysql:8.0.16

4. 启动容器成功

MySQL 容器状态变为up
