CentOS 上的 MariaDB docker 容器無法啟動

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"

執行 docker-compose up -d 後，容器不斷重啟，執行時可以看到以下內容docker logs --tail 50 --follow --timestamps 01e2489d4526

這是docker ps輸出：CONTAINER ID IMAGE

   COMMAND                  CREATED             STATUS                         PORTS                    NAMES

我將如何解決這個問題，記住我還需要能夠從其他容器連接到 mariadb 容器？

謝謝

啟用 SELinux 後，容器的捲應放置在/var/lib/docker/volumes. 主目錄中的捲將具有不允許 Docker 容器訪問它們的 SELinux 上下文。

您需要關閉容器，./mysql/mysql.sock從主機中刪除並重新啟動它。出於某種原因，那裡已經有一個套接字文件，需要將其刪除才能正確啟動服務。
