How to install pdo driver in php docker image?
提问by k0pernikus
I am using as a base the php docker containerwith the tag:
我使用带有标签的php docker 容器作为基础：
php:5.6-apache
I linked it with a basic mysql:5.6image which I can reach at the host mysql. I created a DB, and filled a table with basic values.
我将它与mysql:5.6我可以在主机上访问的基本图像相关联mysql。我创建了一个数据库，并用基本值填充了一个表。
Yet trying to access my app, I get:
然而试图访问我的应用程序，我得到：
Fatal error: Uncaught exception 'PDOException' with message
could not find driver' in /var/www/html/index.php:30
Stack trace: #0 [internal function]:

#11 [internal function]: Phalcon\Mvc\Model\MetaData->_initialize(Object(Rev in /var/www/html/index.php on line 30
Hence, I thought that the php container was lacking the php-mysqlcomponent I installed via:
因此，我认为 php 容器缺少php-mysql我通过以下方式安装的组件：
apt-get install php5-mysql
I also added a mysql.ini at:
我还在以下位置添加了一个 mysql.ini：
cat /usr/local/etc/php/conf.d/mysql.ini
; configuration for php MySQL module
; priority=20
extension=pdo_mysql.so
If I echo phpinfo();dieit tells me that:
如果我echo phpinfo();die告诉我：
Additional .ini files parsed:
/usr/local/etc/php/conf.d/mysql.ini,
/usr/local/etc/php/conf.d/phalcon.ini
Yet still, the error persists.
然而，错误仍然存在。
Furthermore, when running:
此外，在运行时：
php -i|grep PDO
I get:
我得到：
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20131226/pdo_mysql.so' - /usr/local/lib/php/extensions/no-debug-non-zts-20131226/pdo_mysql.so: cannot open shared object file: No such file or directory in Unknown on line 0
PDO
PDO support => enabled
PDO drivers => sqlite
PDO Driver for SQLite 3.x => enabled
so it seems the mysql extension isn't even activated.
所以似乎 mysql 扩展甚至没有被激活。
What am I doing wrong?
我究竟做错了什么？

The official repository of PHP has a script called
docker-php-ext-installhttps://github.com/docker-library/php/tree/master/5.6
PHP 的官方仓库有一个脚本叫做
docker-php-ext-installhttps://github.com/docker-library/php/tree/master/5.6
You forgot to install the extension needed to run the PDO.
您忘记安装运行 PDO 所需的扩展。
Try do create a docker image like this:
尝试创建一个像这样的 docker 镜像：
FROM php:5.6-apache
# PHP extensions
RUN docker-php-ext-install pdo pdo_mysql pdo_pgsql
