Hello everyone,
Everything was going well with the Magento 2.1.0 development.
I started with Centos 6.7 and then upgraded to 6.8 for Magento 2.1.0.
I made a mistake of entering chmod -R 777 /var on the SSH terminal and ever since then I have been getting. This /var is from root, not magento2/var.
"There has been an error processing your request" message, with
Warning: SessionHandler::read(): open(/var/lib/php/session/sess_1ta198b5mgb0q8gk27b3kq2gh1, O_RDWR) failed: Permission denied (13) in /var/www/html/magento2/vendor/magento/framework/Session/SaveHandler/Native.php on line 22
The Error log record number: 482217899148, shows:

I have reset the /var folder to 755, then set magento2, magento2/var, magento2/pub to 777 and then magento2/pub to 755, but I am still receiving permission errors.
What can I do to revert back to the original Centos 6.8 directory/file permission settings so that I can retrieve the site I am working on? I've tried reindexing, flushing the cache and even resetting all the folders and files permissions to what it should be (I have another server with a replicated environment).
It seems like it's a simple permission setting but I can't figure it out for the life of me.
Thank you in advance for your help.

Solved! Go to Solution.
Panic subsides...
It was a rather simple permission error.
sudo chmod 777 /var/lib/php/session/
It solved the problem for both Magento and PhpMyAdmin!

I have also noticed that I am not able to access phpmyadmin...
phpMyAdmin - Error
Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly. Also ensure that cookies are enabled in your browser.
Any help in resolving this issue is greatly appreciated.
