Linux – Migrating from physical Red Hat to EC2 virtualised CentOS/other

amazon ec2centoslinuxredhatSecurity

I am migrating a classic LAMP application from Red Hat 5.3 to EC2, and cannot find a CentOS 5.3 image in the community to meet my needs. I don't have time to roll my own AMI. Creating my own repo and updating Amazon's stock Fedora 8 has so far proved difficult, and I am concerned that using it as a base will expose security holes, although the kernel has been updated to 2.6.21.7-2.

Can anybody recommend a RHEL5.3 binary compatible AMI?
If not, where is the information on backported security fixes to the Fedora 8 repo? I was under the impression it had reached EOL.

The idea of running Fedora 8 in production is abhorrent to me – can anybody explain why it's offered by Amazon and whether it's suitably patched?

How about using the Amazon AMI?

The first thing to do in this situation is to use the -v option to ssh, so you can see what types of authentication is tried and what the result is. Does that help enlighten the situation?

In your update to your question, you mention "on another local Ubuntu". Have you copied over the ssh private key to the other machine?

Ok i figured out. I created a file CentOs.repo (/etc/yum.repos.d/CentOs.repo) with the following contents :

[CentOS-Base]
name=CentOS-Base
mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=os
gpgcheck=1
enabled=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

name=CentOS-Updates
mirrorlist=http://mirrorlist.centos.org/?release=5&arch=$basearch&repo=updates
gpgcheck=1
enabled=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
