Subdomain htaccess issue in Magento

问题

public_html/                    # www.domain.com
public_html/subdomain             # subdomain.domain.com
public_html/.htaccess
public_html/subdomain/.htaccess

I have a subdomain subdomain.domain.com

I have .htaccess file under public_html

This htaccess file contains this code:

Options -MultiViews

RewriteEngine On
RewriteBase /

ReWriteCond %{HTTP_HOST} ^subdomain\.domain\.com$
ReWriteCond %{REQUEST_URI} !^/subdomain/
ReWriteRule ^(.*)$ /subdomain/$1

I need to install magento inside subdomain folder

.htaccess file inside this folder is:

<IfModule mod_rewrite.c>

RewriteEngine on
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?/$1 [L,QSA]

</IfModule>

Magento Installed successfully, But I am facing a problem:

http://subdomain.domain.com/admin (this url works)

but when I hit http://subdomain.domain.com/index.php/admin its shows "No input file specified."

All internal URLs in admin are also throwing same error.

Please help me what wrong I put in my htaccess

Thanks in advance.
