如何在php docker映像中启用pdo_mysql [英] How to enable pdo_mysql in the php docker image

问题描述

我有一个基本的Dockerfile，其中包含以下内容:

I have a basic Dockerfile with the following in:

FROM php:7.1-apache
RUN apt-get update && docker-php-ext-install pdo_mysql
COPY . /var/www
EXPOSE 80

我有一个docker-compose.yml文件

I have a docker-compose.yml file

version: "3"
services:
  app:
    build: .
    ports:
      - "80:80"
    volumes:
      - .:/var/www
    depends_on:
      - mysql
  mysql:
    image: mysql:8
    ports:
      - "3306:3306"
    environment:
      MYSQL_DATABASE: "app"
      MYSQL_USER: "app"
      MYSQL_PASSWORD: "app"
      MYSQL_ROOT_PASSWORD: "test"

然后我在项目的根目录下运行docker build -t app . && docker-compose up.一切似乎都正确构建，但是在输出phpinfo时，我看不到mysql_pdo扩展名.

I then ran docker build -t app . && docker-compose up at the root of the project. Everything seems to build correctly, but when outputting phpinfo I don't see the mysql_pdo extension.

我缺少任何步骤吗?

推荐答案

我使用的docker文件是...

The docker file I use is...

FROM php:7.1-apache
COPY apache2.conf /etc/apache2
RUN docker-php-ext-install mysqli pdo pdo_mysql

请注意其中的mysqli和pdo，以允许PDO/mysql位.

Note the mysqli and pdo in there as well to allow the PDO/mysql bit.
