Sharepoint 2016 onpremise how to change central admin url domain?

Question

I Installed Sharepoint 2016 on premise in a Windows Server 2016, however the installation used the machine's name to generate the url, so currently when I open my Central Administration of Sharepoint I have a very unfriendly url like:

http://win-8si9e41b3h3

And everything is using this domain, so if I access to my sites I have http://win-8si9e41b3h3/sites/projects.

How can I change it to something like:

http://mydomain.com/everything-else

Thanks and Regards!!

Answer 1

Generally, the central admin URL would be with below format after installing the SharePoint:

http://machinename:portnumber

Here the port number will be the one that you have given during the installation.

The MSDN article says CA port number can be changed using the below PowerShell command:

Set-SPCentralAdministration -Port 8282(example - you can give your own number)

MSDN Source:

Set-SPCentralAdministration

You can try the above step.

And also we can change the central administration URL by other ways:

Answer 2

it is recommended that you need to create a separate web application (other than CA) for regular use. CA web application is back-end work and it is only provision on 1 server and if you have multi-server environment then it will not provision on other servers ( Web front ends).

what i recommend:

1. Create DNS Alias which point to the server or Load balancer
2. Create a Web Application in the Central admin and use the DNS in it
3. Create a root level site collection
4. Update the AAM via central admin

Lastly, in your case, you have to backup the existing Site collection and Restore it to new web application.
