docker上的Wordpress不运行

wordpress docker docker-compose

docker上的Wordpress不运行,wordpress,docker,docker-compose,Wordpress,Docker,Docker Compose,这是我的docker-compose.yml version: '2' services: wordpress: image: wordpress ports: - "8080:80" environment: WORDPRESS_DB_PASSWORD: example db: image: mysql:5.7 environment: MYSQL_ROOT_PASSWORD: example 服务正常运行，

这是我的docker-compose.yml

version: '2'
services:
  wordpress:
    image: wordpress
    ports:
      - "8080:80"
    environment:
      WORDPRESS_DB_PASSWORD: example
  db:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: example

服务正常运行，但几秒钟后，wordpress容器停止

这是我的docker日志wordpress容器：

links:
   - db:mysql

为什么会发生这种情况？

您是否在撰写文件wordpress服务中设置了DB主机（以及其他所需的MySql属性）（而不是帖子中显示的密码）？e、 g:

特别是“主机”值，在您的设置中应该是

db

。你不必做任何链接，尽管添加链接是个好主意

depends_on:
  - db

到您的wordpress服务块，它将设置在wordpress容器之前启动db容器的依赖顺序。（一个

links

属性也可以做同样的事情，但要尽量保持简单。）

注:

默认情况下，Compose为您的应用程序设置单个网络。每个服务的容器加入默认网络，并且是可由该网络上的其他容器访问，并可由它们的主机名与容器名称相同

链接允许您定义服务使用的额外别名可从其他服务访问。不需要它们来启用要通信的服务-默认情况下，任何服务都可以到达任何其他服务以该服务的名称提供服务

除非您真正了解自己在做什么，否则我不会在网络上乱搞，因为在大多数情况下，默认设置都可以正常工作。如果您有一些特殊情况，您可以在以后对其进行优化。

我没有使用yml，但有相同的日志，这不起作用

docker run -dP --link elated_yonath -e WORDPRESS_DB_USER=libik -e WORDPRESS_DB_PASSWORD=prdik wordpress

但后来我发现，我必须添加：mysql到链接容器中

docker run -dP --link elated_yonath:mysql -e WORDPRESS_DB_USER=libik -e WORDPRESS_DB_PASSWORD=prdik wordpress

现在它开始了。

解决方案：

记住将mysql容器链接到wordpress容器：

links:
   - db:mysql

像这样：

version: '2'
services:
  wordpress:
    image: wordpress
    ports:
      - "8080:80"
    links:
      - db:mysql
    environment:
      WORDPRESS_DB_PASSWORD: example
  db:
    image: mysql:5.7
    environment:
      MYSQL_ROOT_PASSWORD: example

这个重要的细节没有在

上提到，这对我来说很有效，因为我没有足够的声誉去投票。安瑟，我复制到这里：

取决于：
-分贝

这只是确保数据库容器在

wordpress

容器之前已完全加载。您需要告诉docker从

wordpress

容器链接

db

容器，以按名称引用它

docker compose

在引擎盖下所做的是获取ip docker提供的

db

容器，并向

wordpress

容器添加一个

/etc/hosts

条目，以便您可以按名称引用它

因此，请尝试将此添加到wordpress部分

链接：
-分贝

将这些添加到“db:”下为我解决了这个问题

    command: --default-authentication-plugin=mysql_native_password
    restart: always

如前所述，您应该添加

depends_on:
  - db

但在这之后，我仍然收到关于连接问题的消息。只有这个明确的问题——第二个选择：

networks:
    local:

这就解决了错误

主机别名在这里很重要：(
