Having previously shared a post about how to create a serverless reverse proxy using CloudFlare Workers, the long domain name (https://proxy1.51sec.workers.dev) created by this method is not suitable for sharing, so I was consider using my own domain name (https://proxy.51sec.org) to access it. Searched online, but about this piece of information is quite written unclear and difficult to start, so here to make a note for my own reference.

Redhat Openshift made a change from Openshift online 2 to online 3. Deadline is end of Sep 2017. My blog www.51sec.org which was hosted at Red Hat Openshift Online 2 environment for last a couple of years has been migrated from Redhat Openshift Platform to AWS Linux Free Tier a couple of days ago before deadline. At the beginning, migration process was easy and smooth since I am keeping same domain 51sec.org.

Also Wordpress plug-in "All-in-One WP Migration" helped a lot during this process. Whole blog was exported to a 120M package. Unfortunately I still got a problem when access www.51sec.org site later which is running on AWS Linux instance.

There are a couple of issues I found while migration or building new site. This post is a summary those issues I found
1. PHP is out of memory.
2. WordPress Site and Home URL Change
3. Change Upload file limitation 2M

You cannot copy content from 51sec.org.
