CentOS 上的 MariaDB docker 容器无法启动

我有以下docker-compose：

version: "2"
services:
  webserver:
    image: orsolin/docker-php-5.3-apache
    environment:
      ALLOW_OVERRIDE: "true"
      HTTP_PROXY: "${HTTP_PROXY}"
      HTTPS_PROXY: "${HTTPS_PROXY}"
      NO_PROXY: "${NO_PROXY}"
    ports:
      - "8000:80"
    depends_on:
      - db
    volumes:
      - ./app:/var/www/html/

  db:
    image: centos/mariadb-102-centos7
    restart: always
    volumes:
      - ./mysql:/var/lib/mysql/:rw
    environment:
      MYSQL_ROOT_PASSWORD: *redacted*
      MYSQL_USER: *redacted*
      MYSQL_PASSWORD: *redacted*
      MYSQL_DATABASE: *redacted*
      HTTP_PROXY: "${HTTP_PROXY}"
      HTTPS_PROXY: "${HTTPS_PROXY}"
      NO_PROXY: "${NO_PROXY}"
    ports:
      - "8889:3306"

  adminer:
    image: adminer
    restart: always
    environment:
      ADMINER_DEFAULT_DB_DRIVER: mysql
      ADMINER_DEFAULT_DB_HOST: mariadb
      ADMINER_DEFAULT_DB_NAME: adminer
      ADMINER_DESIGN: nette
      ADMINER_PLUGINS: tables-filter tinymce
      HTTP_PROXY: "${HTTP_PROXY}"
      HTTPS_PROXY: "${HTTPS_PROXY}"
      NO_PROXY: "${NO_PROXY}"
    ports:
      - "8282:8080"

运行 docker-compose up -d 后，容器继续重新启动，运行时我可以看到以下内容docker logs --tail 50 --follow --timestamps 01e2489d4526

这是docker ps输出：CONTAINER ID IMAGE

我该如何解决这个问题，记住我也需要能够从其他容器连接到 mariadb 容器？

谢谢

答案1

启用 SELinux 后，容器的卷应放置在 的子目录中/var/lib/docker/volumes。主目录中的卷将具有不允许 Docker 容器访问的 SELinux 上下文。

答案2

您需要关闭容器，./mysql/mysql.sock从主机中删除它，然后重新启动它。由于某种原因，那里已经有一个套接字文件，需要将其删除才能正确启动服务。

答案3

错误很明显，您要么停止其他 mysql 服务，要么更改配置文件中的端口：

[mysqld]

端口= 1234
