Prepare the Configuration File

Complete the following steps to upgrade to Eucalyptus 3.2.2 on CentOS 6 or RHEL 6.

Important

You should already have the repositories installed for euca2ools, EPEL, and ELRepo from your 3.1.x installation. If you do not have these installed, refer to the installation instructions to find out how to add these to your machines.

The steps in this section should be performed on all machines with Eucalyptus installed.

Remove any hand-written repository files for earlier versions of Eucalyptus and Euca2ools from /etc/yum.repos.d.
Install the new Eucalyptus release package on each host that will run a Eucalyptus component:
```
yum install http://downloads.eucalyptus.com/software/eucalyptus/3.2/centos/6/x86_64/eucalyptus-release-3.2.noarch.rpm
```
If you have a Eucalyptus subscription, you will have received a package that grants you access to VMware and SAN components. If you wish to use either of these components, install this package on each host that will run a Eucalyptus component with this command:
```
yum install eucalyptus-enterprise-release-3.2*.noarch.rpm
```
