docker 與 php、nginx、redis，memcached 連接被拒絕 111

Question

我有一個項目，其中包含 Yii2 + nginx + php + redis + 我想要的其他服務，以便每個 php、nginx、redis 位於單獨的容器服務等中...

這不起作用：從 Yii2（另一個容器）訪問 redis？

配置：

文件： /frontend/config/main.php

return [
    'components' => [
    'cache' => [
        'class' => 'yii\redis\Cache',
        'redis' => [
            'hostname' => '127.0.0.1',
            'port' => 6379,
            'database' => 1,
],

Database Exception – yii\db\Exception
Failed to open redis DB connection (tcp://127.0.0.1:6379, database=1): 111 - Connection refused
Error Info: Connection refused

它在本地機器上是 ubuntu 20.04； 我安裝了redis-cli； 我可以從這個 redis 客戶端訪問。

Answer 1

問題是您沒有在 redis 容器中公開端口，這意味着您的機器和其他容器都無法訪問它。 你還需要將它綁定到你的本地端口端口，這樣你就可以通過指向本地主機來訪問它。 您可以在docker 的文檔中進一步閱讀

 redis:
    build:
      context: ./
      dockerfile: ./docker/redis_data/redis.docker
    container_name: mredis
    restart: always
    expose:
      - 6379
    ports:
      - 6379:6379

注意6379端口綁定和暴露的區別*

Answer 2

將您的docker-compose.yml更改為

version: '3'

networks:
  myztt:
    driver: bridge
    ipam:
      config:
        - subnet: 172.18.0.0/16
          gateway: 172.18.0.1

services:
  nginx:
    restart: always
    container_name: mnginx
    build:
      context: ./
      dockerfile: ./docker/nginx/nginx.docker
    ports:
      - "80:80"
    networks:
      myztt:
        ipv4_address: 172.18.0.100
    volumes:
      - ./:/var/www/html/ztt.loc
  php-fpm:
    restart: always
    container_name: mphp
    build:
      context: ./
      dockerfile: ./docker/php/php-fpm.docker
    volumes:
      - ./:/var/www/html/ztt.loc
    networks:
      myztt:
        ipv4_address: 172.18.0.101
  redis:
    build:
      context: ./
      dockerfile: ./docker/redis_data/redis.docker
    container_name: mredis
    restart: always
    networks:
      myztt:
        ipv4_address: 172.18.0.103

並將文件中的連接 url 更改為172.18.0.103：/frontend/config/main.php

'cache' => [
            'class' => 'yii\redis\Cache',
            'redis' => [
                'hostname' => '172.18.0.103',
                'port' => 6379,
                'database' => 1,
            ],
        ],
