Check any customisations and integrations +#. Upload the |sysvm64-version| System VM template if not already using it. +#. Confirm Java 17 is the default Java version +#. Stop all running management servers +#. Backup CloudStack database (MySQL) +#. Upgrade 1st CloudStack management server +#. Update hypervisors specific dependencies +#. Restart 1st management server +#. Check that your upgraded environment works as expected +#. Upgrade and restart the remaining management servers + + +.. include:: _customisation_warnings.rst + +.. include:: _sysvm_templates.rst + +.. include:: _java_version.rst + +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 |release| source, or check the Apache CloudStack downloads page at +http://cloudstack.apache.org/downloads.html +for package repositories supplied by community members. You will need +them for :ref:`ubuntu414` or :ref:`kvm414` hosts upgrade. + +Instructions for creating packages from the CloudStack source are in the +`CloudStack Installation Guide`_. + +Database Preparation +-------------------- + +Backup current database + +#. Stop your management server or servers. Run this on all management + server hosts: + + .. parsed-literal:: + + $ sudo service cloudstack-management stop + +#. If you are running a usage server or usage servers, stop those as well: + + .. parsed-literal:: + + $ sudo service cloudstack-usage stop + +#. Make a backup of your MySQL database. If you run into any issues or + need to roll back the upgrade, this will assist in debugging or + restoring your existing environment. You'll be prompted for your + password. + + .. parsed-literal:: + + $ mysqldump -u root -p -R cloud > cloud-backup_$(date +%Y-%m-%d-%H%M%S) + $ mysqldump -u root -p cloud_usage > cloud_usage-backup_$(date +%Y-%m-%d-%H%M%S) + + +.. _ubuntu414: +.. _apt-repo414: + +Management Server +----------------- + +Ubuntu +###### + +If you are using Ubuntu, follow this procedure to upgrade your packages. If +not, skip to step :ref:`rhel414`. + +.. note:: + **Community Packages:** This section assumes you're using the community + supplied packages for CloudStack. If you've created your own packages and + APT repository, substitute your own URL for the ones used in these examples. + +The first order of business will be to change the sources list for +each system with CloudStack packages. This means all management +servers, and any hosts that have the KVM agent (no changes should +be necessary for hosts that are running VMware or Xen.) + +Edit your ``/etc/apt/sources.list.d/cloudstack.list`` file on +any systems that have CloudStack packages installed to points to version |version| + +This file should have one line, which contains: + +.. parsed-literal:: + + deb http://download.cloudstack.org/ubuntu bionic |version| + +Setup the public key for the above repository: + +.. parsed-literal:: + + wget -qO - http://download.cloudstack.org/release.asc | sudo apt-key add - + +#. Now update your apt package list: + + .. parsed-literal:: + + $ sudo apt-get update + +#. Now that you have the repository configured, it's time to upgrade + the ``cloudstack-management`` package. + + .. parsed-literal:: + + $ sudo apt-get upgrade cloudstack-management Review Comment: @weizhouapache this is to upgrade existing cloudstack management with newer version, upgrade is fine here? install also work the same way or re-installs it (can overwrite any config files)? -- This is an automated message from the Apache Git Service.
