I am trying to install October on a linux ubuntu vps with mysql using the Wizard. The installation fails at the "Create Admin Account" stage, with the following error is returned:

SQLSTATE[HY000] [1698] Access denied for user 'root'@'localhost' (SQL: select * from information_schema.tables where table_schema = database and table_name = migrations)

So, I assume the installation process is trying to access the database with the mysql root user. If this is the case, I am unsure why, as I have provided an existing mysql username and password with access to the database, and these are written into the database.php file.

Does anyone have any ideas?

The database.php file contains the following:

<?php

Did you add the database details into the installer or the file itself. If its into the file itself while doing the install (cant remember if there's validation there or not) but it may try and overwrite the database.php file.

Thanks for your response! No, the details were added via the installer forms. It's weird, I just can't get it to work. Since posting this, i have had the install say it worked, but when I try to access the admin area ('backend'), well there is no backend to access, despite having agreed to the installation defaults, and entered admin information. I have tried every permutation i can think of, to no avail.

Weird! Might be worth checking the config/cms.php file to make sure the 'backendUri' => '/backend', is set correctly. Also may be worth checking the app.php to see if the url is correct, just in case that may be stopping it.

This is an error I have gotten before on several installations. By simply pressing retry it always resolved itself. My guess was that it might be an issue that the database has to create too many tables in one go. Hope it is this easy for you to solve the problem as well.

I managed to overcome the problem SQLSTATE [HY000] [1698] Access denied for this 'root' @ 'localhost' user by installing using a theme. My problem is solved.
