Setting up WordPress

Hello,

I am relatively new to the whole back end side of things when it comes to setting up a site. I have done so using BlueHost and other hosting services.

At the moment, I am working on installing WordPress and getting set up on a “staging” site. The hosting is through a private party (not a BlueHost or anything just a company the client has been using for quite some time)

I logged in to the ftp using FileZilla and created a staging folder, downloaded and unzipped WordPress and uploaded it to the staging directory on the ftp. When I go to examplesite.com/staging I get a prompt to set up wp-config.php file.

I have entered the Database Name and login that was provided by the developer (it was the same info used to log in to the ftp) This did not work, I got an error saying it was unable to connect.

I contacted the developer and they suggested using localhost in the Database Host field. I did that and used the same login info and got a different screen that said, unable to set up wp-config.php file and that I have to do this manually.

I’m guessing I don’t have a localhost set up? Can anyone provide basic and clear step by step instructions or know what I’m doing wrong? I love learning this stuff but am a designer by trade so clear simple step by step is helpful. I have looked at many of the forum pages on here already for setting up a localhost but still have questions… Does this mean the site will be run on my personal computer? If I shut my computer off will the “staging” site go down?

Thank you in advance for any and all advice/help.
