This guide explains how to upgrade OnApp Cloud v4.3 to the v5.0 for the cloud where all servers are static.Follow the procedure listed below in the correct order to upgrade your cloud. All packages (Control Panel and Compute resources) must belong to the same major version to ensure the best performance of your cloud.

Important Notes


  1. You must be running the latest patch of OnApp 4.3 version to upgrade to 5.0 version. If you are using an earlier version, please upgrade to 4.3.first.
  2. Check the Activity Log in your OnApp CP dashboard if there are no transactions running in your cloud. If so, wait until all transactions are complete.
  3. Make sure no Control Panel files are open for editing under the root user account.

  4. If you are using a third-party billing platform, please ensure that this is compatible with OnApp 5.0 before proceeding with the upgrade! The latest WHMCS modules can be found here.

  5. If you are using WHMCS modules, make sure to update the PHP Wrapper after you update OnApp Cloud. Download the latest wrapper.

  6. Be aware that from now on, OnApp Licensing has a standalone client.Use only 443 port to connect from Control Panel to licensing server.
  7. We strongly recommend that you test all your custom scripts before upgrading your production environment.

  8. Be aware that OnApp does not support UEFI on static compute resources. You should disable UEFI on your compute resources before installing OnApp.

Upgrade Static Compute Resources


At first upgrade your static compute resources.

  1. Make sure your compute resource is visible and online in the Control Panel.

  2. Download and install the latest OnApp YUM repository file:

    bash#> rpm -Uvh http://rpm.repo.onapp.com/repo/onapp-repo-5.0.noarch.rpm
  3. Upgrade OnApp compute resource installer package:

    yum update onapp-hv-install
  4. Update your server OS components (if required):

    For XEN compute resource:

    bash# /onapp/onapp-hv-install/onapp-hv-xen-install.sh -y

    For KVM compute resource:

    bash# /onapp/onapp-hv-install/onapp-hv-kvm-install.sh -y
  5. Run compute resource installer:
    For XEN compute resource:

    bash# /onapp/onapp-hv-install/onapp-hv-xen-install.sh 

    For KVM compute resource:

    bash# /onapp/onapp-hv-install/onapp-hv-kvm-install.sh

    Reboot XEN compute resource, which is running on CentOS 6.x, after upgrade to 4.4.3 XEN version.

  6. Reboot static compute resources.

    For KVM compute resources only: the kernel package update is a part of "Upgrade Static Compute Resources" default procedure. So reboot is required, if kernel package was upgraded and customer is willing Compute Resource(s) running it (for security reason).

    If you do not have the /home/mq/onapp/messaging/credentials.yml file on your compute resources and you plan to deploy an Accelerator, run the following command on the CP server:

    • For all compute resources:

      rake hypervisor:messaging:configure


    • For certain compute resources only:

      rake hypervisor:messaging:configure['11.0.50.111 11.0.50.112']

      To perform the configuration for a number of compute resources, separate their IPs with a space.

      For information on manual configuration for Accelerator, refer to RabbitMQ Configuration for Accelerator.

Upgrade Static Backup Servers


After you upgraded static compute resources, proceed to static backup servers upgrade.

  1. Download the OnApp repository:

    bash#> rpm -Uvh http://rpm.repo.onapp.com/repo/onapp-repo-5.0.noarch.rpm
  2. Update the package:

    yum update onapp-bk-install
  3. Run the following script:

    bash#>/onapp/onapp-bk-install/onapp-bk-install.sh
  4. Update your server OS components (if required):

    bash#> /onapp/onapp-bk-install/onapp-bk-install.sh -y



Upgrade Control Panel Server



To upgrade your Control Panel server:

  1. If you are using a remote RabbiMQ server, make sure the onapp user on the Control Panel has SSH access to that remote server:

    su onapp
    ssh root@<ip addrees>


  2. Stop the Monit service:

    # service monit stop
  3. Run the following command from the CP server to stop the OnApp service:

    service onapp stop
  4. Download and install the latest OnApp YUM repository file:

    bash#> rpm -Uvh http://rpm.repo.onapp.com/repo/onapp-repo-5.0.noarch.rpm
  5. Upgrade OnApp Control Panel installer package:

    bash#> yum update onapp-cp-install


  6. Update your server OS components (if required):

    bash# /onapp/onapp-cp-install/onapp-cp-install.sh -y
  7. (Optional) If you need some custom Control Panel configuration, set the values before the installer script runs.

    -u MYSQL_USERMySQL user. Default is 'root'


    REDIS_*Options are useful if Redis Server is already installed and configured.
    --redis-host=REDIS_HOST


    IP address/FQDN where Redis Server runs.
    The Redis Server will be installed and configured on the current box if localhost/127.0.0.1 or box's public IP address (listed in SNMP_TRAP_IPS) is specified.
    If local Redis, it will serve as well on the unix socket '/tmp/redis.sock'.
    Default value is 127.0.0.1.
     --redis-bind[=REDIS_BIND]The IP address for Redis Server to serve connections (to listen). The option is not mandatory.
    --redis-port=REDIS_PORTRedis Server listen port.
    Defaults are:
    0 - if local server
    6379 - if remote server
    --redis-passwd[=REDIS_PASSWD]Redis Server password to authentificate.
    Random password is generated if the option's argument isn't specified.
    By default no password is used for local Redis.
    --redis-sock[=REDIS_SOCK]Path to the Redis Server's socket. Used if local server only.
    Default is /tmp/redis.sock. The socket is unset if the option's argument is not specified.


    ADMIN_*Options are used to configure OnApp Control Panel administrator data.
    Please note, that these options are for NEW INSTALL only and not for upgrade
     -P ADMIN_PASSWDCP administrator password
    -F ADMIN_FIRSTNAMECP administrator first name
    -L ADMIN_LASTNAMECP administrator last name
    -E ADMIN_EMAILCP administrator e-mail


      --rbthost   RBT_HOST  IP address/FQDN where RabbitMQ Server runs. The RabbitMQ will be installed and configured on the current box if localhost/127.0.0.1 or box's public IP address (enlisted in SNMP_TRAP_IPS) Default values are 127.0.0.1.
    VCD_*Options are usefull if vCloud/RabbitMQ are already installed and configured.
    --vcdlogin  VCD_LOGINRabbitMQ/vCloud user. Default value is 'rbtvcd'.
    --vcdpasswd VCD_PASSWDRabbitMQ/vCloud user password. The random password is generated if isn't specified.

    --ha-installProceed with Control Panel and High Availability components installation
    --rake RAKE_TASKSList of OnApp Control Panel rake tasks (separated with space) to run at the very end of install or upgrade.
    -v ONAPP_VERSIONInstall custom OnApp CP version
    -i SNMP_TRAP_IPS

    IP addresses separated with coma for snmp to trap

    The '-i' option has higher priority than 'on_app.yml'/'onapp-cp.conf' files.
    In case of the Control Panel upgrade with the '-i' option the snmp address will be overwritten in the 'on_app.yml'/'onapp-cp.conf' files.

    During the Control Panel upgrade without the '-i' option the 'on_app.yml' file has higher priority than the 'onapp-cp.conf' file.
    In this case the snmp address will be taken from the 'on_app.yml' file and the 'onapp-cp.conf' file will be overwritten.


    -c CONFIG_FILECustom installer configuration file. Otherwise, preinstalled one is used.
    -yupdate OS packages (except of OnApp provided) on the box with 'yum update'.
    -aDo not be interactive. Process with automatic installation. Please note, this will continue OnApp Control Panel install/upgrade even if there is transaction currently running.
    -tAdd to the database and download Base Templates. For new installs only. If this option is not used, then only the following mandatory System Templates will be added by default during fresh install: OnApp CDN Appliance; Load Balancer Virtual Appliance; Application Server Appliance.
    --noservices

    Do not start OnApp services: monit, onapp and httpd
    Please note, crond and all OnApp's cron tasks remain running. They could be disabled by stopping crond service manually for your own risk.

    -Ddo not make database dump, and make sure it is disabled in the cron and not running at the moment
    -hprint this info

    You may wish to reboot your Control Panel server to take advantage of a new kernel if it is installed. It is not required immediately as a part of the upgrade process though.

    Customers running vCloud integration pay attention that upgrade process can take some time, as vCloud and OnApp synchronization is running along with OnApp upgrade.


    Perform the following steps if you plan to deploy Accelerator. Otherwise skip.


  9. If you plan to configure an Accelerator, run the following command:

    • For all compute resources:

      rake hypervisor:messaging:configure
    • For certain compute resources only:

      rake hypervisor:messaging:configure['11.0.50.111 11.0.50.112']

      To perform the configuration for a number of compute resources, separate their IPs with a space.

    The command above runs on compute resources that are online. If some compute resources are offline, you should run the command again when they are online.

    The rabbitmq_host parameter in the on_app.yml file should contain the real IP address of the server with RabbitMQ installed. The rabbitmq_host parameter should not be set to 'localhost' or '127.0.0.1'.

    The server with RabbitMQ installed should be available from the compute resources.



    For information on manual configuration for Accelerator, refer to RabbitMQ Configuration for Accelerator.

If you face the problem with viewing the maps on VS/Smart/Application server creation wizard (Locations step), refer to the Add Google Map API Key document.
