This section describes how to upgrade from Abiquo 4.7.0 or above to the current Abiquo version. Please contact Abiquo Support for further information.

...

Prepare branding

• If you are upgrading from Abiquo 4.7.x, the new UI in Abiquo 5.0 requires new branding. See Abiquo branding guide

...

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

Stop platform services

Make snapshots and backups of all platform servers

The upgrade to Abiquo 5.2.x is a major upgrade with upgrades of third-party software packages that are critical platform dependencies

You MUST make snapshots of all servers in your platform before you upgrade to Abiquo 5.2.x.

...

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

1. Check that the Abiquo RabbitMQ queues are empty on the Abiquo Monolithic Server, Abiquo Server or Datanode server

   The number of messages in all queues must be 0.

   Code Block
   # rabbitmqctl list_queues messages name

   Code Block

   # rabbitmqctl list_queues messages name Listing queues ... 0 abiquo.am.notifications 0 abiquo.bpm.notifications 0 abiquo.datacenter.requests.ADatacenter.bpm 0 abiquo.datacenter.requests.ADatacenter.virtualfactory 0 abiquo.ha.tasks 0 abiquo.nodecollector.notifications 0 abiquo.pcrsync.messages 0 abiquo.pcrsync.parking-expect-no-consumers 0 abiquo.scheduler.fast.requests 0 abiquo.scheduler.requests 0 abiquo.scheduler.slow.requests 0 abiquo.tracer.traces 0 abiquo.virtualfactory.notifications 0 abiquo.virtualmachines.definitionsyncs 0 abiquo.vsm.eventsynk ...done.

2. On the V2V Server, check for any active conversions by checking for the V2V or Mechadora processes

   Code Block
   $ ps aux | grep v2v $ ps aux | grep mechadora

When user VM operations are blocked and all of the above checks show that no tasks are running, it is safe to halt the platform.

...

Back up the main platform elements

To perform a basic backup of the platform, run the following backups:

# On DB server, back up the Abiquo MySQL DBs
mysqldump --routines --triggers kinton            > kinton.sql-$(date +%Y%m%d_%H%M%S)
mysqldump --routines --triggers kinton_accounting > kinton_accounting.sql-$(date +%Y%m%d_%H%M%S)

# On the Monitoring server, back up Watchtower DB
mysqldump --routines --triggers watchtower            > watchtower.sql-$(date +%Y%m%d_%H%M%S)

# On the Abiquo API Server or UI server, back up the UI
tar cvfz /var/www/html/ui.tgz-$(date +%Y%m%d_%H%M%S) /var/www/html/ui

# If you are using SAML authentication with multiple IdPs, on ALL Abiquo API Servers, back up this file
cp 
/opt/abiquo/tomcat/webapps/api/WEB-INF/classes/springresources/security/saml/security-saml-generated-beans.xml /opt/abiquo/tomcat/webapps/api/WEB-INF/classes/springresources/security/saml/security-saml-generated-beans.xml-$(date
 +%Y%m%d_%H%M%S)

# On ALL servers, back up the /opt/abiquo folder
tar cvfz /opt/abiquo.tgz-$(date +%Y%m%d_%H%M%S) /opt/abiquo

# On Abiquo Monolithic or API Server, Remote Services, or Datanode, back up Redis
redis-cli save
cp -a /var/lib/redis /var/lib/redis-$(date +%Y%m%d_%H%M%S)

...

Disable old billing dashboards and delete last bills

In Abiquo 5.2, the billing dashboard feature is now in the core Abiquo platform.

If you are using the billing dashboard scripts from previous versions, disable them and delete last bills before you continue with the upgrade.

1. On the server where you were running the billing packages, remove the Cron jobs to run the billing scripts.

   Code Block
   # rm /etc/cron.d/abiquo-billing-ec2 # rm /etc/cron.d/abiquo-billing-arm

2. Delete the last bills from the previous version of the billing dashboards (from the kinton.billing_consolidation and kinton.billing_register tables). Remove the bills for Azure and Amazon providers, for the number of months covered by the abiquo.enterprise.property.billing.monthoffset property, which has a default value of 2 months. Later the new billing dashboards feature will regenerate these bills.

...

Stop platform services

This section describes how to stop platform services on all servers.

To stop platform services:

1. Stop the API on the API server or Monolithic server

   Code Block
   systemctl stop abiquo-tomcat

2. Stop the UI on the API server or Monolithic server or dedicated UI server

   Code Block
   systemctl stop httpd

3. StopRemote services server

   Code Block
   systemctl stop abiquo-tomcat

4. Stop the database on the Monolithic server or Database server or Datanode server.

   Code Block
   systemctl stop mariadb

   For a datanode configuration, you will also need to stop the Galera cluster. For more details, see Stop and start HA configuration

5. Stop RabbitMQ (on the monolithic server or API Server or Datanode)

   Code Block
   systemctl stop rabbitmq-server

6. V2V server -
   You do not need to stop anything because the BPM remote service is run on-demand only

7. Stop monitoring server

   Code Block
   systemctl stop abiquo-delorean systemctl stop abiquo-emmett systemctl stop kairosdb systemctl stop cassandra

8. On the monitoring server, check if Cassandra is really dead

   Code Block
   ps auwx | grep cassandra

   Get the process number for Cassandra (the first number in the output of the previous command), and kill it. In this example, Cassandra is process 12345.

   Code Block
   kill -9 12345

All processes on platform servers should now be halted.

...

Make snapshots and backups of all platform servers

The upgrade to Abiquo 5.2.x is a major upgrade with upgrades of third-party software packages that are critical platform dependencies

You MUST make snapshots of all servers in your platform before you upgrade to Abiquo 5.2.x.

...

Prepare yum repositories on all servers

• Check that you have the repository URL and credentials

• To upgrade to a version with a patch number of zero, for example, version 5.2.0

• OR To upgrade to a version with patch number that is not zero, for example, version 5.2.1, enable both repositories:

  Code Block
  yum-config-manager --enable abiquo-base yum-config-manager --enable abiquo-updates

• Optionally add your username and password to the Abiquo repos

  Code Block
  yum-config-manager --save --setopt=abiquo-*.username=MYUSERNAME yum-config-manager --save --setopt=abiquo-*.password=MYPASSWORD

Don't forget to use a backslash to escape any shell special characters. For more details, see https://www.oreilly.com/library/view/learning-the-bash/1565923472/ch01s09.html

• Clean yum and make cache

yum clean all && yum makecache

• If you did not make snapshots of all servers already, then do this now

...

Upgrade Datanode servers in HA

In a HA environment, RabbitMQ and MySQL may be together on a Datanode server.

Abiquo will upgrade to new versions of RabbitMQ and MySQL that require a manual upgrade path of dependencies.

1. Shut down the Galera cluster. See Stop and start HA configuration.

2. Remove the Erlang and Galera packages.

   Code Block
   yum remove erlang* galera yum clean all && yum makecache

3. Install new RabbitMQ and MariaDB server

   Code Block
   yum install rabbitmq-server MariaDB-server

   Before you confirm, check that the packages will be installed from the abiquo-base repository

   1. rabbitmq-server: 3.8.2.1

   2. MariaDB-server: 10.4.10.1

4. Upgrade Abiquo to 5.2.x

   Code Block
   yum update

   Before you confirm, check the following packages will be installed from the abiquo-base repository:

   1. jdk: 11.0.6u10

   2. redis: 5.0.7.1

5. Enable the new services

   Code Block
   systemctl enable mariadb systemctl enable rabbitmq-server

6. Edit the MySQL configuration to use the new version of Galera.

   The configuration file can be found at

   Code Block
   /etc/my.cnf.d/galera.cnf

   Change the wsrep_provider line to use the new version of Galera (in the galera-4 folder)

   Code Block
   wsrep_provider=/usr/lib64/galera-4/libgalera_smm.so

7. Start Galera, which will also start MySQL.

   Check the Galera state data.

   Code Block
   cat /var/lib/mysql/grastate.dat

   Find the server which is safe to bootstrap

   Code Block
   safte_to_bootstrap: 1

   Start Galera

   Code Block
   galera_new_cluster

   On the other servers in the cluster, start MariaDB

   Code Block
   systemctl start mariadb

   For more details see Stop and start HA configuration
   

8. Start RabbitMQ on all datanode servers

   Code Block
   systemctl start rabbitmq-server

9. Upgrade MySQL on all datanode servers

   Code Block
   mysql_upgrade

   The mysql_upgrade step may detect errors that trigger messages such as the following:

   Code Block
   kinton_accounting.ACCOUNT_PERIOD_USAGE_VW Error : Column count of mysql.proc is wrong. Expected 21, found 20. Created with MariaDB 100129, now running 100410. Please use mysql_upgrade to fix this error

   These messages are expected and this same mysql_upgrade process will automatically fix these errors in its next stages.

   Check that the mysql_upgrade process completes correctly.

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

11. Upgrade the Abiquo API databases. This script is available on the API Server.

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

    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.

...

Upgrade UI servers in HA

This step is for standalone UI servers only.

1. On each separate UI Server, upgrade Abiquo.

   Code Block
   yum clean all && yum makecache yum update

   This will update Abiquo to version 5.2.x.
   Remember to perform the UI configuration steps later in the upgrade before restarting the HTTP service.

...

Upgrade load balanced API servers in HA

This step is for API servers in an HA environment, where there is a separate datanode that contains the database and RabbitMQ.

1. On the API servers, upgrade Abiquo to 5.2.x

   Code Block
   yum update

   Before you confirm, check the following packages will be installed from the abiquo-base repository:

   1. jdk: 11.0.6u10

   2. redis: 5.0.7.1

2. Check versions of Java and Tomcat

   Check that the symbolic link to the latest version of Java points to Java 11

   Code Block
   # cd /usr/java # ll latest -> /usr/java/jdk-11.0.6+10

   Check that the correct Tomcat version will be used

   Code Block

   # cd /opt/abiquo/tomcat/bin # sh version.sh Using CATALINA_BASE: /opt/abiquo/tomcat Using CATALINA_HOME: /opt/abiquo/tomcat Using CATALINA_TMPDIR: /opt/abiquo/tomcat/temp Using JRE_HOME: /usr Using CLASSPATH: /opt/abiquo/tomcat/bin/bootstrap.jar:/opt/abiquo/tomcat/bin/tomcat-juli.jar NOTE: Picked up JDK_JAVA_OPTIONS: --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.rmi/sun.rmi.transport=ALL-UNNAMED Server version: Apache Tomcat/9.0.33 Server built: Mar 11 2020 09:31:38 UTC Server number: 9.0.33.0 OS Name: Linux OS Version: 3.10.0-1160.15.2.el7.x86_64 Architecture: amd64 JVM Version: 11.0.6+10 JVM Vendor: AdoptOpenJDK

   On the API Server in the JDK folder, check certificate migration for AM download. The API Server certificate should be listed for Java 11 with its FQDN. You may need to enter the storepass option to supply the password and you can use the alias option to search for the hostname or FQDN of your server

   Code Block
   # cd /usr/java/jdk-11.0.6+10/lib/security # keytool -list -keystore cacerts -alias (hostname or fqdn)

   For example

   Code Block
   sudo keytool -list -keystore cacerts -alias abiquo.example.com

3. On the API Servers, change file permissions so the Abiquo services can run as the tomcat user (not root) and allow access to the configuration files

   Code Block
   chown -R tomcat /opt/abiquo

...

Upgrade remote services servers

These steps are for remote services servers in a distributed or HA environment.

Upgrade EVERY remote services server with these steps.

1. On the remote services servers, upgrade Abiquo to 5.2.x

   Code Block
   yum update

   Before you confirm, check the following packages will be installed from the abiquo-base repository:

   1. jdk: 11.0.6u10

   2. redis: 5.0.7.1

2. After the update, check versions of Java and Tomcat

   Check that the symbolic link to the latest version of Java points to Java 11

   Code Block
   # cd /usr/java # ll latest -> /usr/java/jdk-11.0.6+10

   Check that the correct Tomcat version will be used

   Code Block

   # cd /opt/abiquo/tomcat/bin # sh version.sh Using CATALINA_BASE: /opt/abiquo/tomcat Using CATALINA_HOME: /opt/abiquo/tomcat Using CATALINA_TMPDIR: /opt/abiquo/tomcat/temp Using JRE_HOME: /usr Using CLASSPATH: /opt/abiquo/tomcat/bin/bootstrap.jar:/opt/abiquo/tomcat/bin/tomcat-juli.jar NOTE: Picked up JDK_JAVA_OPTIONS: --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.rmi/sun.rmi.transport=ALL-UNNAMED Server version: Apache Tomcat/9.0.33 Server built: Mar 11 2020 09:31:38 UTC Server number: 9.0.33.0 OS Name: Linux OS Version: 3.10.0-1160.15.2.el7.x86_64 Architecture: amd64 JVM Version: 11.0.6+10 JVM Vendor: AdoptOpenJDK

   On the remote services server in the JDK folder, check certificate migration to allow AM download

   The API server certificate should be listed for Java 11 with its FQDN. You may need to enter the storepass option to supply the password and you can use the alias option to search for the hostname or FQDN of your server

   Code Block
   # cd /usr/java/jdk-11.0.6+10/lib/security # keytool -list -keystore cacerts -alias (hostname or fqdn)

   For example

   Code Block
   sudo keytool -list -keystore cacerts -alias abiquo.example.com

3. On all remote services servers using SSL

   Edit the Tomcat server configuration file:

   Code Block
   /opt/abiquo/tomcat/conf/server.xml

   Find the location of the certificate files for Java 8

   Code Block
   keystoreFile="/usr/java/default/jre/lib/security/cacerts"

   Change it to the location for Java 11 (e.g. remove "/jre")

   Code Block
   keystoreFile="/usr/java/default/lib/security/cacerts"

Upgrade Remote Services servers

Upgrade Monitoring server

2. On all remote services servers, change file owners to tomcat user

   Code Block
   chown -R tomcat /opt/abiquo

3. On the remote services with appliance manager and the V2V server (i.e. servers that mount the NFS repository), change file owners to Tomcat user

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

   
   

...

Upgrade monitoring server

This step is for Watchtower monitoring servers in all installations.

1. To continue using Java 8 (for Cassandra), remove the JDK through the package manager.
   If you use yum, it will be delete all the dependencies and you will have to reinstall them

   Code Block
   rpm -e --nodeps jdk

2. Check the jdk to install is version 8

   Code Block
   rpm -qa | grep jdk

3. Check that Java is correctly installed:

   1. If you execute this command and get that error, please execute the command from the next bullet:

      Code Block
      $ java -bash: java: command not found

   2. Fix it by executing this command, then selecting the option
      "java-1.8.0-openjdk.x86_64 (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.292.b10-1.el7_9.x86_64/jre/bin/java)":

      Code Block
      $ sudo alternatives --config java There are 3 programs which provide 'java'. Selection Command ----------------------------------------------- 1 /usr/java/jdk1.8.0_144/bin/java + 2 /usr/java/jdk-11.0.6+10/bin/java * 3 java-1.8.0-openjdk.x86_64 (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.292.b10-1.el7_9.x86_64/jre/bin/java) Enter to keep the current selection[+], or type selection number: 3

4. As for the Abiquo DB steps, remove Galera, which will also remove MariaDB

   Code Block
   yum remove galera

5. Clean yum and make cache

   Code Block
   yum clean all && yum makecache

6. Install MariaDB

   Code Block
   yum install MariaDB-server

7. Update Abiquo

   Code Block
   yum update

8. Check that the Java package is now "javajdk" to use Java 1.8.0u144 with Cassandra:

   Code Block
   # rpm -qa 'javajdk*' javajdk-1.8.0u144-6691.el7.x86_64

9. If you have a HA datanode that runs the watchtower database, skip directly to Step 10 to update watchtower database

10. Enable and start the services that were reinstalled

    Code Block
    systemctl enable mariadb systemctl start mariadb

11. Upgrade MySQL

    Code Block
    mysql_upgrade

    The mysql_upgrade step may detect errors that trigger messages such as the following message (note: this example is from the Abiquo database server).

    Code Block
    kinton_accounting.ACCOUNT_PERIOD_USAGE_VW Error : Column count of mysql.proc is wrong. Expected 21, found 20. Created with MariaDB 100129, now running 100410. Please use mysql_upgrade to fix this error

    These messages are expected and this same mysql_upgrade process will automatically fix these errors in its next stages.

    Check that the mysql_upgrade process completes correctly.

12. Update the Abiquo Watchtower database

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

13. Edit the file /opt/kairosdb/conf/kairosdb.properties to update the name of the following variable and to remove the port from it:

    1. Remove the line kairosdb.datastore.cassandra.host_list=192.168.888.999:9160.
       And add this line kairosdb.datastore.cassandra.cql_host_list=192.168.888.999.
       Please note the new cql_ prefix for host_list

    2. Add kairosdb.datastore.cassandra.datapoint_ttl = 15768000 (ref: Internal JIRA SUP-333):

14. Edit the file /etc/cassandra/conf/cassandra.yml OR /etc/cassandra/default.conf/cassandra.yaml (whichever exists) to remove a variable:

    1. Remove the line starting with kairosdb.datastore.cassandra.datapoint_ttl and save and close the file.

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. Reporting changes: To upgrade the Abiquo Reports database for the upgrade to Abiquo 4.7.x+, contact Abiquo Support for the file and procedure.

...

Start Abiquo servers and services

To start the Abiquo platform servers and services, do these steps:

1. On the Abiquo server, restart the HTTP daemon to refresh the user interface files, and bring up the Tomcat server.

   Code Block
   service httpd start service abiquo-tomcat start

2. On the Remote services server, start the Tomcat server

   Code Block
   service abiquo-tomcat start

3. On the Monitoring server do these steps.

   1. In the file /opt/kairosdb/conf/kairosdb.properties check that you have the cql_host_list variable (with no port, and not the host_list variable):

      1. For example, kairosdb.datastore.cassandra.cql_host_list=192.168.888.999.

   2. Check that you have kairosdb.datastore.cassandra.datapoint_ttl = 15768000

   3. Check that the following line is not in your Cassandra configuration
      (/etc/cassandra/conf/cassandra.yml OR /etc/cassandra/default.conf/cassandra.yaml):

      1. Remove the line starting with kairosdb.datastore.cassandra.datapoint_ttl

4. On the Monitoring server, start the Cassandra service

   Code Block
   sudo service cassandra start

5. WAIT about 5 minutes until the service is up and running

6. Start the KairosDB service

   Code Block
   sudo service kairosdb start

7. Start the other services in this order

   Code Block
   sudo service abiquo-emmett start sudo service abiquo-delorean start

8. On the V2V server: restart the Tomcat server:

   Code Block
   service abiquo-tomcat restart

9. In Abiquo, re-enable the physical machines!

10. Clear your browser cache to prevent glitches in the UI
