Migrating from Windows to Linux - Database Error

Postby ss32 » 25. March 2015 20:46

I'm new to XAMPP and need to migrate an old page from Windows to Linux. I have a fresh install and all of the demos work fine. When I move the contents of the htdocs folder over from the Windows install I get a 403 Error when loading localhost, which I fixed by changing permissions of htdocs to 755. Now I'm getting an error "Error establishing a database connection" and not sure where to go from here. Here are the permissions for /opt/lamp

Its not a question of file permissions, you have to apply some valid MySQL User Data and password. You must look into the PHP source code and find out, which data is required.

When you say which data is required, what specifically do you mean? I have no experience with MySQL before this. When I go to localhost/phpmyadmin I see a list of users, would it be one of these that needs to be granted access? Edit: Is there a speicifc php file that might have the relevant information?

If you have no experience, you cannot solve this. You have to know PHP and PHP MySQL API and must apply a valid User and password for mysql connect, this is quite impossible without any experience.

This is very common practice, but i have not the faintest idea about your software project.

Or I could learn how to do this right now.

Surely there is a standard file structure; the configuration files can't vary that much. If it helps, here are the contents of /opt/lampp/htdocs
