How to point a registered domain on Public IP


I have a CentOS 7.

I have purchased a new domain name

I want to configure this domain name on my centOS 7 server

I have installed httpd on centos 7 and my site working fine as localhost but I want to open this site using purchased domain name.

Please help to configure domain name on centos 7.

I will deeply appreciate it.

Thank You

Hello "UncleSamCrazy",

Firstly the manual pages for httpd should indicate the location of the primary config files, man httpd

Typically the file is called httpd.conf and is normally located at /etc/httpd/conf indicates that the variable / environment variable used to store the domain is called ServerName
so simply substitute the entry in the file containing ServerName with ServerName simply substitute the .com with the appropriate value, i.e., etc. 80 here refers to the port no. that you will be serving the pages from, typically port 80

1. Always remember to take a backup copy of any config file before you amend it.
2. After modifying the config file remember to restart the httpd service

Hope that helps.

In addition to the above, you'll need to configure DNS such that points to the public IP address of your Web server. Do you have DNS servers set up to resolve your domain yet? If not, godaddy and others have DNS services you can use (I remember zoneedit having a free option back in the day, but it's been ages since I've looked).

You'll also need to make sure your firewall is configured to allow traffic on port 80 and port 443 (if using HTTPS) to the server.

I have done the httpd part as well as opening port 80, 443 in iptables and firewall.

I am facing problem in DNS part, I have a public IP and any one in this world can open my site using this public IP but it is difficult to give people public IP that's why I have purchased domain but how to point this purchased domain to my public IP.

Please help.

You don't need (or want) BIND.
Your registrar (where you got the domain name from) will host the DNS records.

Never is my vote, you only need BIND if you really want to run your own DNS server, which can cause lots of headaches from extra DNS problems you don't need. I've hosted public websites for some years without BIND, I use my registrar's DNS servers. They have a nice web-based DNS manager.

You use the DNS manager to add a DNS host record for your site, usually using the www host, pointing to your public IP address.

One more thing, you need to make sure your internet provider isn't blocking http traffic on your internet connection.

You might find it useful to read about "A" Records. Domain registrars are normally responsible for maintaining those.

Doug G gives good advice in post #8. In the US at least, most ISP's prohibit public-facing servers unless you are paying for a "business" connection; some enforce the prohibition more actively than others, usually by blocking port 80.
