Question

我创建了一个docker compose文件来运行mysql docker容器并使用数据库脚本初始化数据库。

启动容器时，出现以下错误。

account-service-db_1  | Initializing database
account-service-db_1  | mysqld: Can't create/write to file '/var/lib/mysql/is_writable' (OS errno 13 - Permission denied)

经过研究，许多人建议在撰写文件中添加用户：“ 1000：50”将解决该问题。但是在添加后，我也遇到相同的错误。

请在下面找到我的docker-compose文件

version: '3.7'

services:
 account-service-db:
    user: "1000:50"
    image: mysql
    environment:
      - MYSQL_DATABASE=account-service
      - MYSQL_USER=mysqluser
      - MYSQL_PASSWORD=mysqlpassword
      - MYSQL_ROOT_PASSWORD=mysqlpassword
    volumes:
      - "/Users/admin/dockerfiles/docker-swarm-account-service-mysql-demo/scripts/:/docker-entrypoint-initdb.d/"
      - "/Users/admin/dockerfiles/docker-swarm-account-service-mysql-demo/account:/var/lib/mysql" 
    ports:
      - "3306:3306"

    deploy:
     replicas: 1
     placement:
      constraints:
       - node.labels.mysql.node == true
     restart_policy:
      condition: on-failure
      delay: 10s
      #max-attempts: 3

我正在Mac机器上执行上述方案。给卷和脚本文件夹提供所有必要的权限后，请帮助我为什么它会如此显示。

问题似乎出在您的account文件夹中。它可能已经在使用中或已损坏。创建一个新文件夹并进行测试。

从撰写文件的环境值中删除双引号。

如果正在安装的主机上的文件夹没有所需的写权限：

SSH到您的主机/节点
chmod -R a+rwx /path/to/account/folder

mysql docker容器未启动，mysqld：无法创建/写入文件'/ var / lib / mysql / is_writable'（OS errno 13-权限被拒绝）
