Error establishing a database connection

Hi,

Generally “Error Establishing Database Connection” error notification occurs for a obvious reason if any database configuration setting option values are not appropriately set.

And following are required parameters to look out for:
a) Database name
b) Database username
c) Database password
d) Database host

If all the above parameters are well set & confirmed then check if the database is set up properly & running or is their any issue from web hosting providers end.

Also to ensure things are correct with database, just create a blank plain PHP file & check if database connection works.

Hope this will help to sort out your issue.

Thanks.

Hi,

Database can be created using PHPMyAdmin, or any Mysql Client.

There is a nice description already posted on codex help guide. I am sharing a link for reference, and a help guide to setup a database before doing an installation:

If required please contact to your web hosting provider for an assistance over database setup.

Thanks.
