Sep 04 17:28:47 rhel7 httpd[2303]: AH00557: httpd: apr_sockaddr_info_get() failed for rhel7


Solution:

In this case the rhel7 is the actual hostname for this system. To fix the above error message :

# echo 'ServerName 127.0.0.1' >> /etc/httpd/conf/httpd.conf

and restart your apache webserver daemon httpd to apply changes:

# service httpd restart
