Thanks #Ermin But lemme know is it mandatory to install apache.Actually im hosting in aws.So can we do this with out installing apache ?

You'll need a proxy server, for many different reason (such as port redirection from 8069 to 80/443 for example), but also for this purpose. This has nothing to do with AWS (we are also on AWS). There are several options for proxy servers: Apache, nginx are the most popular. Actually we are testing caddy server (www.caddyserver.com) because it seems to be quite easy and has inbuilt let's encrypt certification and automatic renewal. Please upvote my answer and check it as solved.

Can we solve it by editing in odoo-server.conf file ?

You might be able to achieve it without a proxy server by adding the proper host names in the host file together with the dbfilter parameter in the conf file (which is anyway needed, also if you deploy a proxy server). Check my amended answer.
