Is it possible to reinstall httpd service or changig hostname

In httpd.conf, search for "ServerName". It's usually commented out by default. Just uncomment it and fill it in. Make sure you also have the name/ip combo set in /etc/hosts.

but does http://localhost work?

http://localhost also not working it displays blank page in web browser

I check the server name it is not in commented,It is fine and I check /etc/hosts also that also contains the name/ip combo set.
everything is ok then why this problem is coming?

When you do
Try making the "ServerName" 127.0.0.1 and see if that works.

This doesn't look correct
There shouldn't be a leading dot in '.localdomain' AFAIK...

Problem solved
When HTTPD is try to start that time it was unable to provide valid ssl certificate.SSL not get the correct certificate.
Why it is happen because my cmos battery is ended due to this my system date is differant than current date so ssl certificate not valid which is provided by httpd.
So I change my cmos battery and set my system date with current date and I make ssl certificate checking off by editing in ssl file.
and my HTTPD service get start normally.
