Question

我试图迁移使用Symfony 3.3.12制作的API，该API使用具有基于MariaDb MariaDB 10.0.24的Amazon RDS的数据库安装在AWS上

在我的日志上获取：

好吧，我看不到，或者我不了解有关的信息。

但是我正在调查，并且看到Syfony 3.3 Doctrine manual谈到了这个问题，进一步的搜索显示MariaDB 10.2.7及更高版本存在问题。

好吧，我在原始API上将MariaDb降级为相同版本：

好吧，我编辑了app/config/config.yml，尝试使用5.6和5.2（这是mysql -Version的逻辑值返回

# Doctrine Configuration
doctrine:
    dbal:
        driver:   pdo_mysql
        host:     "%database_host%"
        port:     "%database_port%"
        dbname:   "%database_name%"
        user:     "%database_user%"
        password: "%database_password%"
        server_version: 5.6
        charset:  UTF8

壳

mysql -Version
mysql  Ver 15.1 Distrib 10.0.35-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

配置中的凭据正确无误，并尝试使用端口3306，主机到localhost的其他版本...

parameters:
    database_host: 127.0.0.1
    database_port: null
    database_name: c1farid
    database_user: c1fariduser
    database_password: CorrectPassWorD

更简单。

bin/console cache:clear --env=prod
// Clearing the cache for the prod environment with debug false


[OK] Cache for the "prod" environment (debug=false) was successfully cleared.

不做任何修改，只有我忘记了Exception Doctrine \ DBAL \ DBALException中的 stupid 消息错误。

从AWS / RDS Maria DB 10.0迁移Symfony 3.3.12失败：DBALException
