Keep getting “Error establishing a database connection”

I’m having the same problem

I tried to run the install script after having done all the other steps of the 5-minute installation process. But when I try to run the wp-admin/install.php I keep getting the message “Error establishing a database connection”.

The db-name, username, pw and hostname in the wp-config file should be correct, I checked and double-checked it with my host.

Any ideas?
Thanks

I’m running wp on glassfish with quercus. After the first try everything went smooth and I was up and running in a few minutes. Then I decided to change my domain from my home to /opt/domains. Now wp won’t install and crashes after the enter your setting screen.
“Error establishing a database connection”

I can connect to the database fine with the info a enter. I checked the file permissions and they are RWX by the user running glassfish.

I reached the conclusion the problem isn’t connected to the database connection but the error message is misleading.

Any tips?

I’ve googled it, seems a lot of people have this error message when trying to install it and I haven’t found a clear solution. WordPress should really have a trouble shooting section dedicated to this error message.

Change the host name in the wp-config file from ‘localhost’ to the ip address 213.17X.XXX.XX (replace the X’s with the numbers of the IP address).

This worked for me.

I too was having this problem.

When I put the “echo (mysql_error());” line in wp-db.php as suggested in https://www.railshostinginfo.com/blog/2007/03/19/wordpress-installation-error-establishing-a-database-connection/, I got an error message to the effect that the Connector/J library could not be found.

When I added mysql-connector-java-5.1.7-bin.jar to WEB-INF/lib, the problem went away and wordpress is now working fine.

Hope this helps.

As straydog999 said, you just need to go on your wp-config.php file and when on dabase host, update with localhost (again) or put the address to the server.

This has worked for me a few times.

I’m having the same issue and not being all that technical am having a hard time understanding the solution given here. Can someone maybe paste the updated wp-db.php file here with the correct line oe lines added? Or maybe straydog can tell me how I determine the IP address I need to enter. Thanks!
