Docker多个MYSQL容器
Docker新手在这里。
我想要实现的是除了一个nginx，一个PHP和一个PhpMyAdmin容器之外，还要用docker compose运行多个MySQL容器。
这是我的docker-compose.yml：
version: '3' services: server: build: context: ./ dockerfile: server.docker volumes: - ./:/var/www ports: - "8080:80" links: - app app: build: context: ./ dockerfile: app.docker volumes: - ./:/var/www links: - db_callcenter - db_forecast - db_logistics - db_products - db_rm - db_rma - db_settings - db_tasks - db_users db_callcenter: image: mysql:5.7 environment: - "MYSQL_ROOT_PASSWORD=secret" - "MYSQL_DATABASE=prj_callcenter" ports: - "33061:3306" volumes: - mysql_bkp:/var/lib/mysql db_forecast: image: mysql:5.7 environment: - "MYSQL_ROOT_PASSWORD=secret" - "MYSQL_DATABASE=prj_forecast" ports: - "33062:3306" volumes: - mysql_bkp:/var/lib/mysql db_logistics: image: mysql:5.7 environment: - "MYSQL_ROOT_PASSWORD=secret" - "MYSQL_DATABASE=prj_logistics" ports: - "33063:3306" volumes: - mysql_bkp:/var/lib/mysql db_products: image: mysql:5.7 environment: - "MYSQL_ROOT_PASSWORD=secret" - "MYSQL_DATABASE=prj_products" ports: - "33064:3306" volumes: - mysql_bkp:/var/lib/mysql db_rm: image: mysql:5.7 environment: - "MYSQL_ROOT_PASSWORD=secret" - "MYSQL_DATABASE=prj_rm" ports: - "33065:3306" volumes: - mysql_bkp:/var/lib/mysql db_rma: image: mysql:5.7 environment: - "MYSQL_ROOT_PASSWORD=secret" - "MYSQL_DATABASE=prj_rma" ports: - "33066:3306" volumes: - mysql_bkp:/var/lib/mysql db_settings: image: mysql:5.7 environment: - "MYSQL_ROOT_PASSWORD=secret" - "MYSQL_DATABASE=prj_settings" ports: - "33067:3306" volumes: - mysql_bkp:/var/lib/mysql db_tasks: image: mysql:5.7 environment: - "MYSQL_ROOT_PASSWORD=secret" - "MYSQL_DATABASE=prj_tasks" ports: - "33068:3306" volumes: - mysql_bkp:/var/lib/mysql db_users: image: mysql:5.7 environment: - "MYSQL_ROOT_PASSWORD=secret" - "MYSQL_DATABASE=prj_users" ports: - "33069:3306" volumes: - mysql_bkp:/var/lib/mysql pma: image: phpmyadmin/phpmyadmin environment: - "PMA_USER=root" - "PMA_PASSWORD=secret" ports: - "8001:80" links: - db_callcenter - db_forecast - db_logistics - db_products - db_rm - db_rma - db_settings - db_tasks - db_users volumes: mysql_bkp: 但是没有一个MySQL容器被创build。 当我运行dockerps我得到：
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 0228e9c8a267 phpmyadmin/phpmyadmin "/run.sh phpmyadmin" About a minute ago Up 30 seconds 0.0.0.0:8001->80/tcp prj_pma_1 e6c6b11905f1 prj_server "nginx -g 'daemon ..." 22 minutes ago Up 2 minutes 0.0.0.0:8080->80/tcp prj_server_1 2e7dd484c6e5 prj_app "docker-php-entryp..." 24 minutes ago Up 2 minutes 9000/tcp prj_app_1
更新：
docker日志显示：
Unable to lock ./ibdata1 error: 11
要么
InnoDB: Unsupported redo log format.
我不知道我在做什么错，或者我该如何开始debugging。 任何帮助将主要赞赏。
你不能有多个mysql进程共享相同的数据目录。 在你的撰写文件中，每个数据库容器都使用相同的mysql_bkp卷。 您将需要为每个容器创build一个卷，或者将mysqlconfiguration为使用/var/lib/mysql的唯一子目录来存储数据。
如果您只是从每个数据库服务中删除volumes:键，它们都将获得唯一的匿名卷（因为这是如何configurationmysql映像）。
或者，您可以为每个服务声明和装入一个单独的卷：
services: db_logistics: image: mysql:5.7 volumes: - mysql_bkp_logistics:/var/lib/mysql db_products: image: mysql:5.7 volumes: - mysql_bkp_products:/var/lib/mysql volumes: mysql_bkp_logistics: mysql_bkp_products:
等等。
