使用Docker Compose在端口3307上运行MySQL

标签： mysql docker docker-compose prisma

我正在尝试在一台计算机上创建多个Prisma数据库服务。我无法使用Docker Compose在3306以外的端口上创建MySQL数据库。

docker-compose.yml 

version: '3'
services:
hackernews:
    image: prismagraphql/prisma:1.8
    restart: always
    ports:
    - "${CLIENT_PORT}:${INTERNAL_PORT}"
    environment:
    PRISMA_CONFIG: |
        port: $INTERNAL_PORT
        managementApiSecret: $PRISMA_MANAGEMENT_API_SECRET
        databases:
        default:
            connector: mysql
            host: mysql
            port: $SQL_INTERNAL_PORT
            user: root
            password: $SQL_PASSWORD
            migrations: true
mysql:
    image: mysql:5.7
    restart: always
    environment:
    MYSQL_ROOT_PASSWORD: $SQL_PASSWORD
    volumes:
    - ./custom/:/etc/mysql/conf.d/my.cnf
    - mysql:/var/lib/mysql
volumes:
mysql:

docker-compose.override.yml 

version: '3'
services:
mysql:
    expose:
    - "${SQL_INTERNAL_PORT}"
    ports:
    - "${SQL_CLIENT_PORT}:${SQL_INTERNAL_PORT}"

错误：

变量SQL_INTERNAL_PORT可能具有3307值。您需要将其更改为3306。

此外，您可以删除

    expose:
    - "${SQL_INTERNAL_PORT}"

行。 Mysql已经公开了3306端口。

所有进入集群的应用程序都使用内部端口（在mysql情况下为3306）。外部端口（在部分端口中）只需要外部字通信。

如果您想拥有多个数据库，则需要更改docker-compose，如下所示：

version: '3'
services:
hackernews:
    image: prismagraphql/prisma:1.8
    restart: always
    ports:
    - "${CLIENT_PORT}:${INTERNAL_PORT}"
    environment:
    PRISMA_CONFIG: |
        port: $INTERNAL_PORT
        managementApiSecret: $PRISMA_MANAGEMENT_API_SECRET
        databases:
        default:
            connector: mysql
            host: mysql_first
            port: 3306
            user: root
            password: $SQL_PASSWORD
            migrations: true
        second:
            connector: mysql
            host: mysql_second
            port: 3306
            user: root
            password: $SQL_PASSWORD
            migrations: true
mysql_first:
    image: mysql:5.7
    restart: always
    environment:
    MYSQL_ROOT_PASSWORD: $SQL_PASSWORD
    ports:
     - 3307:3306
    volumes:
    - ./custom/:/etc/mysql/conf.d/my.cnf
    - mysql:/var/lib/mysql

 mysql_second:
    image: mysql:5.7
    restart: always
    environment:
    ports:
     - 3308:3306
    MYSQL_ROOT_PASSWORD: $SQL_PASSWORD

我有同样的问题。我已经创建了这个docker-compose.yml，它可以完美运行。

为您的应用容器添加这些说明（在我的示例中为wordpress）：

environment:
  WORDPRESS_DB_HOST: db-wordpress

（db-wordpress是数据库名称容器）

为您的数据库容器添加以下说明：

container_name: db-wordpress
environment:
  VIRTUAL_PORT: 3307
expose:
  - 3307

您可以创建具有不同端口的任何数据库容器。只需更改虚拟并公开端口即可。对于您的应用程序，容器的数据库名称。

我希望能对某人有所帮助。

就我而言，直到添加MYSQL_TCP_PORT

，我才能更改Mysql端口而不是3306。

因此示例：

version: '3.8'

volumes:
  mysql_data:
    driver: local

services:
  mysql:
    image: mysql:5.7
    volumes:
      - mysql_data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: root
      MYSQL_DATABASE: keycloak
      MYSQL_USER: keycloak
      MYSQL_PASSWORD: password
      MYSQL_TCP_PORT: 3307
    ports:
    - 3307:3307
    expose:
      - 3307
  keycloak:
    image: quay.io/keycloak/keycloak:latest
    environment:
      DB_VENDOR: MYSQL
      DB_ADDR: mysql
      DB_DATABASE: keycloak
      DB_USER: keycloak
      DB_PASSWORD: password
      DB_PORT: 3307
      KEYCLOAK_USER: admin
      KEYCLOAK_PASSWORD: Pa55w0rd
      # Uncomment the line below if you want to specify JDBC parameters. The parameter below is just an example, and it shouldn't be used in production without knowledge. It is highly recommended that you read the MySQL JDBC driver documentation in order to use it.
      #JDBC_PARAMS: "connectTimeout=30000"
    ports:
      - 8040:8080
    depends_on:
      - mysql
