docker启动mysql报错Can't read dir of '/etc/mysql/conf.d/'

执行命令：

docker run -p 3306:3306 --privileged=true 
-v /mysql/data:/var/lib/mysql 
-v /mysql/log:/var/log/mysql 
-v /mysql/conf:/etc/mysql
-e MYSQL_ROOT_PASSWORD=1234 
--name=mysql-server -d mysql:8.0

错误信息：

 [ERROR] [Entrypoint]: mysqld failed while attempting to check config
        command was: mysqld --verbose --help --log-bin-index=/tmp/tmp.6VZosksth2
        mysqld: Can't read dir of '/etc/mysql/conf.d/' (OS errno 2 - No such file or directory)
mysqld: [ERROR] Stopped processing the 'includedir' directive in file /etc/my.cnf at line 36.
mysqld: [ERROR] Fatal error in defaults handling. Program aborted!

从上面报错信息可以看出 mysqld: Can't read dir of '/etc/mysql/conf.d/' （无法读取/etc/mysql/conf.d/目录）。这样就知道原因了，mysql找不到conf.d目录。所以启动容器时指定到conf.d目录

修改命令：

docker run -p 3306:3306 --privileged=true 
-v /mysql/data:/var/lib/mysql 
-v /mysql/log:/var/log/mysql 
-v /mysql/conf:/etc/mysql/conf.d 
-e MYSQL_ROOT_PASSWORD=1234 --name=mysql-server -d mysql:8.0
