Having trouble with database version installing Magento 2

[HolgerD]

Hi all, I'd like to install Magento 2 for some test purposes but during the installation the installer stops on Step 2: Add a Database.

I got the information "Sorry, but we support MySQL version 5.6.0 or later."

I tried to install Magento on "1blu.de" and on "campusspeicher.de" but both hoster don't support MySQL 5.6.x. I also raised a ticket but campusspeicher.de told me that they only support 5.5.x and there is no upgrade planned yet.

Is there a workaround to install Magento on this "old" MySQL version?

Thanks for you feedback

Sorry, there is no workaround. You need to have MySQL 5.6.0 or later.

Hello,

 Try to update the files (of Magento 2.0):

To make it install with MySql 5.5:
setup/src/Magento/Setup/Model/Installer.php
line 79

 const MYSQL_VERSION_REQUIRED = '5.5.0';//was 5.6.0

vendor/magento/framework/DB/Adapter/Pdo/Mysql.php
line 2122

                if (($indexData['TYPE'] == AdapterInterface::INDEX_TYPE_FULLTEXT)) {// && $this->isNdb($table)

lines 2356-2363

} elseif ($cDefault == Table::TIMESTAMP_INIT) {
// $cDefault = new \Zend_Db_Expr('CURRENT_TIMESTAMP');
$cDefault = false;
} elseif ($cDefault == Table::TIMESTAMP_UPDATE) {
// $cDefault = new \Zend_Db_Expr('0 ON UPDATE CURRENT_TIMESTAMP');
$cDefault = false;
} elseif ($cDefault == Table::TIMESTAMP_INIT_UPDATE) {
// $cDefault = new \Zend_Db_Expr('CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP');
$cDefault = false;

To hide the Advanced Search link because it does not work with this modification.

Rename the files:
vendor/magento/module-catalog-search/view/frontend/layout/catalogsearch_advanced_index__.xml
vendor/magento/module-catalog-search/view/frontend/layout/default__.xml

Do not use this for production website !

I wouldn't recommend trying to run Magento 2 with MySQL 5.5 even if the workaround is possible. 

Here's a discussion with the Magento 2 team about Magento 2 and MySQL 5.5:-
