remove Apache 2 Test Page and show my current website. I don't know how to do it, the process as below.
For more detail, please contact me.
So how can I make the Apache test page go away?
Simple open your /var/www/[login to view URL] file and modify it or delete file (though it might trigger new error). Under Red Hat Enterprise Linux/CentOS/Fedora Core, rename or delete a file /etc/httpd/conf.d/[login to view URL] to make sure you do not see Apache test page.
You may now add content to the directory /var/www/html/. Note that until you do so, people visiting your website will see default page and not your content. To prevent this page from ever being used, follow the instructions in the file /etc/httpd/conf.d/welcome.conf.
