Prevent cloud users from performing VM operations

1. In the UI in the Infrastructure view, select each physical machine and click Disable
2. Using the API, set the state of each physical machine to DISABLED

...

Check for operations in progress on the platform

Before you shut down the platform servers you should check that no operations are in progress.

...

Back up the main platform elements

...

Stop platform services

...

Make snapshots and backups of all platform servers

This is a major upgrade, so we recommend that you make a snapshot and/or a backup of your platform servers.

...

Prepare yum repositories for 6.0 or 6.0.x or 6.1 or 6.1.x

Prepare yum repositories for 6.0.x or 6.1.x

...

Upgrade packages on ALL servers

These instructions are for monolithic, distributed, and HA environments.

1. Check in your RS server(s) if there is an NFS shared folder for the NARS results (related to the system property abiquo.nars.async.fileresults.path):

   Code Block
   language bash
   $ mount | grep -i "nfs\|results" | grep -v sunrpc 10.60.37.87:/abq-pro-nfs on /opt/abiquo/results-nars type nfs4 (rw,nosuid,nodev,noexec,relatime,sync,vers=4.1,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=10.60.37.77,local_lock=none,addr=10.60.37.87,user)

   
   

2. Unmount the previous shared folder if you have it mounted:

   Code Block
   language bash
   sudo umount /opt/abiquo/results-nars

   
   

3. Update Abiquo packages:

   Code Block
   yum clean all && yum makecache && yum update 'abiquo-*'

   
   

4. Mount again the shared folder from the second step.

   Code Block
   language bash
   sudo mount -a

   
   

5. The Abiquo services must run as the tomcat user (not root), so set the required permissions and enforce the use of the package configuration files.
   If you have a MONOLITHIC SERVER do all of the following steps on the Monolithic server

   1. On Abiquo server and remote services

      Code Block
      chown -R tomcat /opt/abiquo

      
      

   2. On the remote services with appliance manager and the V2V server (i.e. servers that mount the NFS repository)

      Code Block
      chown -R tomcat /opt/vm_repository chmod -R a+r /opt/vm_repository

      
      

   3. On the V2V server, check the /etc/sysconfig/abiquo/ec2-api-tools file exists.
      The file must contain the following configuration. If the file does not exist, create it and add this configuration.

      Code Block
      title For CentOS 7
      EC2_HOME=/opt/aws

      
      

Update the Abiquo databases

1. Check that your hostname is in your DNS or in your /etc/hosts file

2. Upgrade the Abiquo API databases

   Code Block
   abiquo-db [-h DB hostname] [-P DB port] [-u user] [-p password] update

   
   

3. If the Liquibase update fails with a message similar to the following: 

   Code Block
   Liquibase update Failed: Validation Failed: 1 change sets check sum src/X.X.X-XX/kinton-X.X.X.xml::ABICLOUDPREMIUM-XXXX-XxxxxxxxXXxXxxxxxxXxxxxx::XXXXXXXXX is now: 7:ee2fa6e058ec76c7abf801567898917d For more information, use the --logLevel flag

   Do the following steps

   1. Clear the database checksums

      Code Block
      abiquo-db clearCheckSums

      
      

   2. Retry the above abiquo-db update command.

4. To upgrade the Abiquo Watchtower database, on the monitoring appliance, run the command below:

   Code Block
   watchtower-db [-h DB hostname] [-P DB port] [-u user] [-p password] update

   
   

5. Reporting: The Abiquo reports server now runs with JasperReports v7.8.0

...

Upgrade additional elements

By default, you will find the upgrade scripts (e.g. for Redis definitions) on the Abiquo Server under the folder: /usr/share/doc/abiquo-redis/redis/

For each upgrade step, run the Redis database script to remove old VSM definitions, which can be found in the 4.2.3 subfolder

On remote services server:

...

# cd /usr/share/doc/abiquo-redis/redis/
# bash ./4.2.3/00-old-vsm-definitions.sh

 If you have custom billing queries, please update them now.

Configure Abiquo after the upgrade

1. Before you start the Abiquo tomcat server, add Abiquo configuration properties to the abiquo.properties file.
   By default the abiquo.properties file is found in the /opt/abiquo/config/ folder.
   See Changes to Abiquo configuration properties

2. Configure the user interface. The default UI location is /var/www/html/ui.
   Optional: Add custom labels and translations in the lang_xx_XX_custom.json files in the lang folder
   Add custom configuration to client-config-custom.json. See Configure Abiquo UI
   If your API is not in the same domain as the UI, set the API endpoint pointing to your Abiquo API server:

   Code Block
   { "config.endpoint": "http://myAPIserver/api" }

   
   

3. SAML: If you are using SAML with multiple IDPs, restore the configuration as described at Restore SAML security beans after upgrade.

4. Start Abiquo server and services
