[alert] (EAI 2)Name or service not known: mod_unique_id: unable to find IPv4 address of

If httpd (apache) is not working, restart fail then you need to check for error log. Once I got the error as

"[alert] (EAI 2)Name or service not known: mod_unique_id: unable to find IPv4 address of "

In order to resolve this issue you will need to check /etc/hosts and make sure that the hostname entry is correct.

Example of correct hosts enty is as below :

 root@neptun [~]# cat /etc/hosts127.0.0.1               localhost.localdomain localhostYour server ip            server.domain.com serverroot@neptun [~]#

How can I retrieve the raw Apache access logs for my site?

You can retrieve the Raw Access Logs for your site(s) by logging in your cPanel and following the link "Raw Access Logs".

The Error log for your site is kept separately from the Access logs. It can be found by logging in Cpanel and following the link "Error Log"
