二 解决步骤

图示解析

1.通过命令查询日志文件地址
docker inspect --format '{{.LogPath}}' 容器ID
2.通过cat命令 读取日志文件
cat 日志地址
通过日志内容,可以看出主要是不能读取'/etc/mysql/conf.d/目录
修改之前的容器启动命令
-v /mydata/mysql/conf:/etc/mysql 修改为-v /mydata/mysql/conf:/etc/mysql/conf.d

docker run --name mysql -d  -p 3306:3306 
 -v /mydata/mysql/log:/var/log/mysql 
-v /mydata/mysql/data:/var/lib/mysql 
-v /mydata/mysql/conf:/etc/mysql/conf.d  
-e MYSQL_ROOT_PASSWORD=123456  mysql

重新执行命令就可以启动成功了。
