我使用带有标签的php docker容器作为基础:
php:5.6-apache
我将它与mysql:5.6可以在主机上找到的基本图像链接在一起mysql。我创建了一个数据库,并用基本值填充了表。
mysql:5.6
mysql
但是尝试访问我的应用程序,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]: PDO->__construct('mysql:host=mysq...', 'root', 'root', Array) #1 [internal function]: Phalcon\Db\Adapter\Pdo->connect(Array) #2 /var/www/html/index.php(30): Phalcon\Db\Adapter\Pdo-__construct(Array) #3 [internal function]: {closure}() #4 [internal function]: Phalcon\Di\Service->resolve(NULL, Object(Phalcon\Di\FactoryDefault)) #5 [internal function]: Phalcon\Di->get('db', NULL) #6 [internal function]: Phalcon\Di->getShared('db') #7 [internal function]: Phalcon\Mvc\Model\Manager->_getConnection(Object(Reviews), NULL) #8 [internal function]: Phalcon\Mvc\Model\Manager->getReadConnection(Object(Reviews)) #9 [internal function]: Phalcon\Mvc\Model->getReadConnection() #10 [internal function]: Phalcon\Mvc\Model\MetaData\Strategy\Introspection->getMetaData(Object(Reviews), Object(Phalcon\Di\FactoryDefault)) #11 [internal function]: Phalcon\Mvc\Model\MetaData->_initialize(Object(Rev in /var/www/html/index.php on line 30
因此,我认为php容器缺少php-mysql通过以下方式安装的组件:
php-mysql
apt-get install php5-mysql
我还在以下位置添加了mysql.ini:
cat /usr/local/etc/php/conf.d/mysql.ini ; configuration for php MySQL module ; priority=20 extension=pdo_mysql.so
如果我echo phpinfo();die告诉我:
echo phpinfo();die
Additional .ini files parsed: /usr/local/etc/php/conf.d/mysql.ini, /usr/local/etc/php/conf.d/phalcon.ini
但是,错误仍然存在。
此外,在运行时:
php -i|grep PDO
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
所以看来mysql扩展甚至没有被激活。
我究竟做错了什么?
PHP的官方存储库具有一个名为https://github.com/docker- library/php/tree/master/5.6的脚本docker-php-ext-install
docker-php-ext-install
您忘记安装运行PDO所需的扩展。
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
