Magento ce 2.3.5 installation fails - DDL statements are not allowed in transactions

Trying to install Magento 2.3.5 CE (wit sample data) on Mac Mojave / Apache 2.4.34 / MySQL 8.0.18

 

Installation gets stuck showing some DDL statements errors. I tried several times to redo this using new databases created in MySQL. but similar errors.

 

Option i chose to install.. default + Magento_SampleData

Re: Magento ce 2.3.5 installation fails - DDL statements are not allowed in transactions

That maybe a solution.. 

create a db_schema.xml file under Vendor/ModuleName/etc

 

  1. But why should we create a new xml file?
  2. Does the product work/install out-of-the-box without such changes to core modules?
  3. Not sure if this is mention din the installation notes?

Hi @surenkonathala 

MySQL version 8.0 is not recommended by Magento doc, it is tested with MySQL 5.6, 5.7.

More more info:

https://devdocs.magento.com/guides/v2.3/install-gde/system-requirements-tech.html

I hope it will help you!
