如何使用docker-php-ext-install安装扩展模块？

2017-03-10 by dongnan

目标

为 php 容器安装 pdo_mysql扩展模块。

问题描述

Uncaught error with message [db.WindConnection.init] could not find driver The server encountered an internal error and failed to process your request. Please try again later. If this error is temporary, reloading the page might resolve the problem. If you are able to contact the administrator report this error message.(http://www.windframework.com/)

环境

php-5.6 on Docker 1.13 on CentOS 7.3
phpwind 9.0

错误原因

检查容器

docker exec -ti ywwd-php php -m | grep -i 'mysql'
mysqlnd

php-5.6 为 PHP官方维护的 docker 镜像，php团队为保持轻量级的镜像，默认没有安装 pdo_mysql模块，所以需要为 php 安装 pdo_mysql扩展模块。

解决方法

进入容器

docker exec -ti ywwd-php /bin/bash

使用官方提供的工具安装扩展模块

docker-php-ext-install pdo_mysql

验证模块

php -m | grep -i 'mysql'
mysql
pdo_mysql

扩展

php5 定制 Dockerfile

软件: php-fpm:5.6 + nginx
