Instead of copying WP to the root, I modified the hppd.conf of apache and pointed the Documentroot to the installed WP. It worked perfectly in the first place. But when I activated network and copied the code to wp_config.php and .htaccess, an error 'The page isn't redirecting properly' was shown after refreshing the page.
The details of what I had done was posted in another post:

I have a few questions...
1. can I do what I did? That is, pointing the root to the installed directory instead of coping the files to the root and tried make multi-site work?
2. can I ractifiy the problem of 'The page isn't redirecting properly'?
3. if 2. is negative, should I reinstall WP?
I am new to linux and wp and I believe I must have do things wrong here or there. However, is there a very detail step by step guide where I can follow to install WP-MU?
Many thanks.
