CHAPTER 8

Upgrade Instruction from 4.2.x

This section will guide you from CloudStack 4.2.x to CloudStack 4.5.

If you run into any issues during upgrades, please feel free to ask questions on [email protected] or

Warning: Depreciation of realhostip.com DNS and SSL certiﬁcate

The realhostip.com dynamic DNS resolution service is being retired this summer. In advance of that, CloudStack

4.3 and later no longer uses realhostip.com DNS domains or SSL certiﬁcates to encrypt Console Proxy or ﬁle copy

communications.

Any steps that are hypervisor-speciﬁc will be called out with a note.

We recommend reading through this section once or twice before beginning your upgrade procedure, and working

through it on a test system before working on a production system.

Note: The following upgrade instructions should be performed regardless of hypervisor type.

Upgrade Steps:

1. Install new System-VM templates

2. Backup CloudStack database (MySQL)

3. Upgrade CloudStack management server(s)

4. Update hypervisors speciﬁc dependencies

5. Restart System-VMs and Virtual-Routers

8.1 Packages repository

Most users of CloudStack manage the installation and upgrades of CloudStack with one of Linux’s predominant

package systems, RPM or APT. This guide assumes you’ll be using RPM and Yum (for Red Hat Enterprise Linux or

CentOS), or APT and Debian packages (for Ubuntu).

Create RPM or Debian packages (as appropriate) and a repository from the 4.5 source, or check the Apache Cloud-

Stack downloads page at http://cloudstack.apache.org/downloads.html for package repositories supplied by commu-

nity members. You will need them for Management Server Ubuntu or Management Server CentOS/RHEL and Hyper-

visor: KVM hosts upgrade.

Instructions for creating packages from the CloudStack source are in the CloudStack Installation Guide.
