Install page can not return successfully

Question is :
1.Why install page can’t return?
2.How can I see my homepage?

I install wordpress follow 5 minute totur,at the last setp ,when I pressed Install button, the page can not return,it just waited.(I had waited 8 hours but no result)So I didn’t get my password.
I googleed about this, maybe it can’t send email to my address.But I’m not sure.

I have tried many times, it can’t be installed successfully.
But in the db ,tables had been created.

I modify admin’s password in db,then access wp-admin/post.php published a test text.

I accessed http://localhost/wordpress in my browser,it just list the dirs and files for me.Click on the index.php will not help.

I’m a beginner of wordpress,so this is too difficult to me.
Thanks for your help
