I have three test sites on the go right now, and it's really easy to do. The basic idea is that you can use the same database, but create a unique set of tables for your test site.
Yes, you will have to have another folder to install WordPress into, but all you need to do is copy over the
wp-config.php file from your existing site, and make one edit, and then run the
install.php script, and you're good to go.
- Create a new folder for your test site, and upload all of the WordPress files into it as you did for your first site.
- Copy the
wp-config.php file from your first site and paste it into your new folder.
wp-config.php and change the line that reads
$table_prefix = 'wp_';' to give your new test site it"s own unique table structure. For example, change the
test_ and then save your changes. You can keep the same DB Name, DB User, and DB Password as well as the DB Host. Don't change any of that.
- Now, navigate to your new folder via your browser, just as you did in the first site, and go to
wp-admin/install.php and run it.
- A new blog will be created as before, and you are ready to go mad with it.
If you're not sure about the instructions, just post back and I'll clarify things for you. You are doing everything exactly the same as when you installed the first blog, except for putting the files into a new folder and changing the default table prefix.
