eucalyptus.html

CentOS 5.5 Mini Cloud using Eucalyptus,Based on,EucalyptusInstallationCentos_v2.0. I'll walk through my own version. This will be a singlesystem at first but hopefully grow to at least a two node system. It doesn't take much to makexen/kvm happy any HT enabled machine from the LGA775's and up.

Now like I noted earlier, I'm cramming allot into one node for now, though I may split the control halfonto my Ubuntu box.. So some of this will be the same as the Euca docs other bits will be different.This writeup though will go from start to finish the most features possible plus a few guest imagesimported and created from scratch.

export VERSION=2.0.2

Depending on your base install this list will be larger or smaller.. First lets make sure somethings areinstalled. This install actually had the kvm and virtualizaiton groups installed already. However theEuca folks have some specific recommendations soo..

Complete!

Before going further do yourself a favor and update!

]# yum -y upgrade

Now per the docs were going to disable a few things on Xen..

sed --in-place 's/#(xend-http-server no)/(xend-http-server yes)/'/etc/xen/xend-config.sxpsed --in-place 's/#(xend-address localhost)/(xend-address localhost)/'/etc/xen/xend-config.sxp/etc/init.d/xend restart

Also we need to make a few security changes, system-config-security-tui can help or just modify thefiles and reboot..SELinux, (really we all need to learn how to make SELinux work for us but I'm with the Euca folksdisable it for now.)

]# grep disable /etc/sysconfig/selinux# disabled - SELinux is fully disabled.SELINUX=disabled

And firewall, for peets sake just make em all the same.. If you really want each one to be different itsup to you.

]# egrep "8443|8773|8774|9001|8775" /etc/sysconfig/iptables-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8443 -jACCEPT-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8773 -jACCEPT-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8774 -jACCEPT-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 9001 -jACCEPT-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8775 -jACCEPT

Now here they say use export version.. I say write the darn version into the repo file..

]# cat /etc/yum.repos.d/euca.repo[euca]name=Eucalyptusbaseurl=http://www.eucalyptussoftware.com/downloads/repo/eucalyptus/2.0.2/yum

/centos/enabled=1

Now again I divert from the doc, just because you install it doesn't mean it must be enabled.. Mynodes will have everything but only one will be configured as a lead node.

yum install eucalyptus-cloud eucalyptus-cc eucalyptus-walrus eucalyptus-sceucalyptus-nc --nogpgcheck

Ok,For now my node controller is an Ubuntu machine for this first attempt I'm going to just try the defaultpackages..

# apt-get install eucalyptus-cc eucalyptus-cloud# sudo apt-get install bittorrent-gui bittorrent

This should trigger a rather large installation including all of the suggested packages from Euca'sdocs. Also apt/dpkgconf will ask alot of configuration questions..(I'll go over them later in a reinstall) Igave it a range from 100-150 of my local sub-net..

On the node you will also need this in both cases it was not installed by default and in the case ofCentOS the quickest repository with it was rpmforge..

rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpmyum install bittorrent

I'll pick this backup / finish it shortly.. publishing it for now..
