Docker:在Windows主机上MariaDB/MySQL启动失败

Question

我正在尝试使用官方的mariadb docker图像以及php-fpm和nginx来运行我的Symfony 2应用程序.

我们的想法是将所有db文件保存在已安装的文件夹中.虽然在Mac OS上它工作得很好 - 在Windows机器上我每次MariaDB尝试启动时都会收到错误.奇怪的是,它实际上能够创建一些文件 - 我可以看到ibdata1文件,但它的大小是0字节.还有两个带有几KB数据的aria_log文件,这意味着mysql实际上可以在那里写入.

• 我正在使用docker for windows 1.12.2 beta.但也试过稳定的.
• 我正在存储项目的Windows磁盘是共享的(通过Docker for Windows UI的"共享驱动器"部分)
• dir是100%可写的,因为nginx甚至mysql本身都可以将它们的日志放在那里
• 正如日志所暗示的那样,我完全没有"磁盘空间不足"

这是我的docker-compose文件:

version: '2'
services:
db:
    image: mariadb
    ports:
        - "3306:3306"
    environment:
        MYSQL_ROOT_PASSWORD: root
        MYSQL_DATABASE: test
        MYSQL_USER: root
        MYSQL_PASSWORD: root
    volumes:
        - ./docker-runtime/mysql:/var/lib/mysql
php:
    build: ./docker/php-fpm
    volumes:
        - ./:/var/www/symfony
        - ./docker-runtime/logs/symfony:/var/www/symfony/app/logs
    links:
        - db
nginx:
    build: ./docker/nginx
    ports:
        - "80:80"
    links:
        - php
    volumes_from:
        - php
    volumes:
        - ./docker-runtime/logs/nginx/:/var/log/nginx

以下是我做的日志所说的内容docker-compose up:

db_1     | 2016-10-18 13:14:06 7f79eed7f7c0 InnoDB: Error: Write to file ./ibdata1 failed at offset 0.

If you tried to add new data files to the system tablespace, and it failed here, you should now edit innodb_data_file_path in my.cnf back to what it was, and remove the new ibdata files InnoDB created in this failed attempt. InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!

我真的很感激这个问题的任何想法,因为我现在正在把我的头发拉出来

Answer 1

您需要在启动 MariaDB 时添加此选项（在 DockerfileCMD或docker -compose 中command:）：

--innodb-flush-method=fsync

它记录在这里：https : //github.com/docker-library/mariadb/issues/95

如果它没有帮助，还添加--innodb-use-native-aio=0.
Windows 和 Mac OS X 不支持异步 I/O：https :

Answer 2

可能您有权限问题。要丢弃，请将您的docker-compose.yml更改为使用命名卷：

version: '2'
services:
db:
    image: mariadb
    ports:
        - "3306:3306"
    environment:
        MYSQL_ROOT_PASSWORD: root
        MYSQL_DATABASE: test
        MYSQL_USER: root
        MYSQL_PASSWORD: root
    volumes:
        - mysql:/var/lib/mysql
php:
    build: ./docker/php-fpm
    volumes:
        - ./:/var/www/symfony
        - ./docker-runtime/logs/symfony:/var/www/symfony/app/logs
    links:
        - db
nginx:
    build: ./docker/nginx
    ports:
        - "80:80"
    links:
        - php
    volumes_from:
        - php
    volumes:
        - ./docker-runtime/logs/nginx/:/var/log/nginx
volumes:
  mysql:

尝试查看mysql错误是否消失。
