Apache's startup often sees such a warning
[root @ Eygle conf] # apachectl starthtpd: could Not Determine the Server's full qalified domain name, use 172.16.11.99 for servername
Just check it, I found a solution.
Your Box's Config Does Not Allow Apache To Find your Server's FQDN (Fully Qualified Domain Name). The reason is that Apache cannot find the server's FQDN (Fully Qualified Domain Name).
The simplest, modify httpd.conf file, increase:
Servername
My change is:
Servername www.eygle.com:80
It's normal to start again:
[root @ Eygle conf] # apachectl stop [root @ eye conf] # Apachectl Start
