#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
 
<PublicIP for EC2> www.example.net

How? Was the WordPress initial settings screen displayed?

Go to wordpress install page http://www.example.net/wp-admin/install.php

After this, set up WordPress, set up DNS settings correctly for production, and set up EC2 security groups appropriately.

Don’t forget to restore your PC’s hosts settings.
