Migration from Fedora to CentOS - centos

I did go through some articles about migrating to CentOS but not specifically from Fedora to CentOS. I'd like to know the steps and measures to follow

I don't think there is a migration path from CentOS to Fedora or vise versa. even though both systems share the same codebase CentOS is way older than Fedora. I used to be a distro hopper way back, but I kept the /home directory in a different drive so I could install any distro I wanted and keep my data and configuration files intact. You should consider doing the same.

how to install bind 9.9.8 or higher on CentOS 5.8

I am running a web server based on CentOS 5.8 and I need to upgrade my version of bind to make it PCI compliant. I'm currently running bind 9.3.6 and I need to have bind 9.9.8 or higher. I've tried yum update bind but apparently I already have the latest version according to yum. I did some Googling and I found an RPM file bind-9.10.2-1.el5.i686.rpm which looks like it would work but i don't know if it should try installing it or not. I think I would need bind-devel and bind-libs which I can get from the same site. Am I better off compiling from source? I know CentOS 5 is old but I'm trying to avoid reinstalling the whole server.
Installing binary rpm's from later versions of CentOS is unlikely to work: there are many changes since CentOS5.
Rebuilding a src.rpm locally is one way to see what issues there are.
Meanwhile, upgrading to CentOS6 (at least: CentOS7 uses systemd which takes some study) is often not a whole lot more effort than retrofitting something like bind, and will have other efficiencies. YMMV, everyone's does.

RHEL vagrantbox (or alternative)

I've been searching for vagrant box for RedHat linux for a week ended up to nothing. Possibly because RedHat, especially the Enterprise Linux, is under commercial used rather than open-sourced.
I've been trying to learn my ways around JBoss with a RedHat Enterprise Linux distribution via Vagrant. Is there a box already present or should I result to alternative box then install and configure JBoss almost similar with RHEL?
Indeed RHEL is not distributed, you need to register with Red Hat to get access to their distribution.
You can use another Red Hat based distribution and it will work almost the same.
the most famous are probably centos as well as Oracle Linux.
You can find those boxes on :
vagrant atlas : https://atlas.hashicorp.com/boxes/search?utf8=%E2%9C%93&sort=&provider=&q=centos
http://www.vagrantbox.es/ has a few boxes that match your need

Update Centos Machine 5.10 to 6.5

I want to update my dedicate Centos Machine, which installed WHM. I want to know that if I do update the OS, there any changes on WHM. Like any default Setting changed? or any other Problems.
So please suggest me that right way of update Centos without any problems, because many websites hosted on this Server.
Thanks
Pankaj Gupta
Pankaj, because there are many changes in a major CentOS release you cannot upgrade from 5.10 to 6.5. You need to put together a migration plan. First install CentOS 6.5 on another server, configure httpd and php/passenger/whichever and test that each hosted website is working properly. Then you can reinstall and reconfigure everything.
Give CentOS 7 a try.
Upgrading is not possible and even if you try around doing some search you will end up wasting lot of time by fixing the dependency related errors etc. So its always better and safe to do a fresh install of CentOS 6.5 and then migrate the sites.

How to host the OpenStreetMap Locally

I want to host the OSM (OpenStreetMap) locally. I need the basic idea what are required for hosting the OSM and how the task can be done in a step wise manner. I have to host it in Windows7 environment.
Any kind of help will be useful.
switch2osm contains detailed instructions and requirements for setting up a OSM server. If you have a Windows system then better set up a Linux VM inside it.
A bit too old but I will just put it here for someone who is searching for the same thing.
An exact instance of OpenStreetMap can be hosted locally by following the installation guide of OpenStreetMap.
Quoting from the Link:
"These instructions are designed for setting up The Rails Port for development and testing. If you want to deploy the software for your own project, then see the notes at the end.
You can install the software directly on your machine, which is the traditional and probably best-supported approach. However, there is an alternative which may be easier: Vagrant. This installs the software into a virtual machine, which makes it easier to get a consistent development environment and may avoid installation difficulties. For Vagrant instructions, see VAGRANT.md.
These instructions are based on Ubuntu 12.04 LTS, which is the platform used by the OSMF servers. The instructions also work, with only minor amendments, for all other current Ubuntu releases, Fedora and MacOSX
We don't recommend attempting to develop or deploy this software on Windows. If you need to use Windows, then try developing this software using Ubuntu in a virtual machine, or use Vagrant."
