Fix the HTTPD “Name or service not known” problem

Resolve error name or service not known

Once you have set up a new domain you will be faced with this error when starting the apache web server:

[Thu May 14 12:38:13.857474 2020] [core:error] [pid 363:tid 140015465703168]
(EAI 2)Name or service not known: AH00547: Could not resolve  name {} -- ignoring!

All this even if the domain you have configured is apparently correct.

    DocumentRoot "/opt/httpd/htdocs/yourapp"
    ErrorLog "logs/error_log"
    ErrorDocument 404 /

The solution is located under one of the server configurations:


In it, the new domain created to be recognized by the Apache web server must be registered.
Once this is done, simply restart the server again and the error will disappear:

httpd -k restart

That’s all.
