如何用教义2创建数据库？

【问题标题】：How to create database with doctrine2?如何用教义2创建数据库？

【问题描述】：

我已经通过 docker 设置了一个新的开发环境。我有一个 symfony2 (2.6) 应用程序，所以我想使用 app/console doctrine 方法初始化 mysql 数据库。

在运行时

$ php app/console doctrine:database:create --if-not-exists

我收到此错误消息：

  [Doctrine\DBAL\Exception\ConnectionException]                                                
  An exception occured in driver: SQLSTATE[42000] [1049] Unknown database 'local_api'  

  [Doctrine\DBAL\Driver\PDOException]                          
  SQLSTATE[42000] [1049] Unknown database 'local_api'

  [PDOException]                                               
  SQLSTATE[42000] [1049] Unknown database 'local_api'

mysql数据库确实不存在。我想首先创建。这是怎么回事？

我找到了bug report for the doctrine/doctrine-bundle，但我们已经在使用固定版本 1.5。

我也找到了symfony2.6 issue，不过升级 symfony2 到 2.7.5 后还是一样。

我知道当我将 direclty 连接到我的 mysql 数据库并运行 CREATE DATABASE local_api 时我可以创建它们，但我希望我的工作流程能够通过学说 2。

只是为了绝对确定该问题与我运行的数据库设置无关：

$ mysql --host=10.10.10.10 --user=foo --password=bar 
mysql> CREATE DATABASE local_api;
Query OK, 1 row affected (0.00 sec)
mysql> Bye
$ php app/console doctrine:database:create --if-not-exists
Database `local_api` for connection named default already exists. Skipped.

然后我可以使用删除数据库

php app/console doctrine:database:drop --force

但由于上述错误，重新创建它再次失败。

尝试通过以下方式清除缓存时也会发生此错误：

./app/console cache:clear

所以这似乎与 symfony2 如何初始化整个数据库堆栈有关。

详细的错误消息如下所示：

【问题讨论】：

  • 好像是an issue in symfony2.6，我需要查一下
  • 刚刚更新到 symfony2.7.5，问题依旧。
  • 刚刚测试，它按预期工作：第一次运行：Created database "project" for connection named default 第二次运行：Database "project" for connection named default already exists. Skipped.
  • 您的用户是否有足够的权限来创建数据库？
  • @lxg 当我直接在 mysql 上创建数据库时，我使用与 symfony2 应用程序相同的凭据，所以是的。

【解决方案1】：

如果您仍然想使用最新版本的doctrine/dbal，您只需在dbal 配置中指定server_version：

doctrine:
    dbal:
        default_connection: default
        connections:
            default:
                dbname:         local_api
                user:           root
                password:       null
                host:           localhost
                driver:         pdo_mysql
                server_version: '5.5' # your database server version here

我无法告诉你为什么他们没有设置默认的 server_version，但这里是关于它的讨论 https://github.com/doctrine/DoctrineBundle/issues/351

由于您使用的是 mysql 数据库，因此查看 server_version 的方法如下：

mysql --version

> mysql  Ver 14.14 Distrib 5.5.44, for debian-linux-gnu (x86_64) using readline 6.3

我们看到当前的 Distrib 是5.5。

当然我建议你在parameters.yml中设置这个值。

【讨论】：

  • server_version 也解决了我的应用程序问题。感谢发帖。
  • 嗨，这解决了我的问题。但是你能解释一下为什么这会奏效吗？我以前从来没有用过这个。发生了什么变化？为什么我需要提供我的 mysql 数据库版本，这没有任何意义？提前致谢！
【解决方案2】：

原来是doctrine/dbal组件中的回归。

我在composer.json 中需要"doctrine/dbal":"2.4.*。

然后它工作正常：

$ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)                                                
  - Removing doctrine/dbal (v2.5.2)
  - Installing doctrine/dbal (v2.4.4)
    Downloading: 100% 

$ php app/console doctrine:database:create
Created database for connection named `local_api`

The issue is known，目前还在等待解决。

【讨论】：

    【解决方案3】：

    老实说，我不知道为什么生成数据库会失败。但是，您也可以手动创建数据库并在命令行上授予所需用户权限，然后让 Doctrine 填充数据库：

    首先，创建数据库并授予权限：

    CREATE DATABASE whatever;
GRANT ALL ON whatever.* TO user@localhost IDENTIFIED BY 'pAsSwOrD';

    然后，让 Doctrine 建立数据库：

    app/console doctrine:schema:update --force --complete

    或者，或者，让 Doctrine 转储它将执行的 SQL 命令：

    app/console doctrine:schema:update --dump-sql --complete

    【讨论】：

    • 我在问题中指出我可以使用mysql客户端创建数据库。我认为这是解决问题的方法，但不是解决方案。
