httpd: apr_sockaddr_info_get() failed for "hostname"

I found error, when I have installed mod_ssl

Starting httpd: httpd: apr_sockaddr_info_get() failed for NGERI

How to fix,

edit /etc/hosts

In the end, add line

127.0.0.1 <hostname> localhost.localdomain

So In my case, I add

127.0.0.1 NGERI localhost.localdomain

Just that. Save, andrestart httpd.
