creating a 2nd blog (config file) after one blog installed

I just upgraded to WP 2.1.3. I have one blog isntalled, where config.php file has db_name: “blog” (located at https://www.sfsro.com/blog). I want to upload to a 2nd folder a 2nd blogsite (say the name address will be https://www.sfsro.com/blog2).

Can someone help? The problem(s) for me is that in the PhpAdmin, the tables are prefixed wp_xxx even though the /blog Config file has db_name: “blog” (if you recall it says to add a prefix wp_ before each database for multiple blogs).

I think I am confusing these two “wp” prefixes when I want to add a second blog (/blog2), and do not know how to do this when the first blog is already installed WITHOUT a prefix (currently “blog” not “wp_blog” which would allow me to just name the 2nd config file in a new folder as db_name: “wp1_blog”).

Since the first blog db_name IS NOT currently “wp_blog” I feel like I cannot title the 2nd blog config db_name correctly if I put a new prefix “wp1_blog” (this would be for blog2). Do I go into the config file for my current blog (db_name: “blog”) and change it to db_name: “wp_blog”, then create a 2nd folder with a 2nd config file replacing “wp_blog” as the db_name with “wp1_blog”.

I want to have 2 installs of wordpress, /blog and /blog2) with 2 cofig files exactly the same EXCEPT the db_name(s) which would now be called “wp_blog” and “wp1_blog” respectively.

This should be simple, but I read over and over again, and the orig. instructions (as most people know, that say to change the prefix wp_, for example, are for some reason not clear to me)…I ask about this because I do not wish to mess up the tables in PhpAdmin by changing the original config. file db_name while NOT changing anything in the SQL db.

Can someone confirm or dispute these actions/tasks so I can know if I am heading in the right direction for having 2 installs on wordpress? Sorry for lots of text but I always appreciate when someone else writes out wordpress questions in everyday “newspaper” type language. Okay, thanks again for any help. I have read on these forums about the problems that can be encountered with multiple installs, but still cannot get past the initial setup questions to take a step toward 2 wp installs.
