Magento 2.1.0 install error

[caleb_van wingerden1]

Hi,

I am using Plesk 12.5.30 on a VPS server with Centos 6.8 using PHP 7.0.27. When I try to install magento 2.1.0 I get the following error:

I already tried this 'solution': http://devdocs.magento.com/guides/v2.2/install-gde/trouble/php/tshoot_session.html but it wouldn't work.

I hope someone can help me with this.

Hi @caleb_van wingerden1,

If you are storing sessions in var folder, please try to give 777 permission to it and check.

I gave the var folder 777 permission using: chmod -R 777 /var/

After that I tried to install magento with Plesk, but I get the same error.

The error you are facing is for Session handler of PHP configuration.

in your php.ini file you need to enable session.save_handler.

you can enable it by uncommenting line - session.save_handler.

So un comment session.save_handler parameter of php.ini file and give its  value like .

session.save_handler = files

For more details magento 2 itself given good guideline to resolve this issue , here is the link - http://devdocs.magento.com/guides/v2.2/install-gde/trouble/php/tshoot_session.html

This is my current php.ini file. I think I don't have to change anything according that solution, but the error is still there.
