1. On your RS server(s) uninstall Docker

   Code Block
   rpm -e --nodeps docker rpm -e --nodeps docker-client rpm -e --nodeps docker-common

2. If you have multiple instances of the NARS Remote Service in your datacenter, check on your RS servers for an NFS shared folder for the NARS results (with the Abiquo configuration 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)

3. Unmount the shared folder. You will remount it after the upgrade

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

...

9. Prepare yum repositories for 6.2 or 6.2.x

Check that you have the repository URL and credentials

...

1. Check that you have the repository URL and credentials

2. To upgrade to the latest version with a patch number that is not zero, for example, version 6.2.x, enable both repositories:

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

3. 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

4. Clean yum and make cache

   Code Block
   yum clean all && yum makecache

5. If you did not make snapshots of all servers already, then you could do this now.

...

10. Upgrade packages on ALL servers

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

1. Update all packages.

   Code Block
   yum clean all && yum makecache && yum update

   The MariaDB update requires a manual install. But first download and run the gpmigrator tool

2. If you earlier unmounted shared folders from your Remote Services server, mount this folder again (and any other folders!)

   Code Block
   language bash
   sudo mount -a

3. 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.

      For CentOS 7

      Code Block
      EC2_HOME=/opt/aws

...

...

11. Run the guest password migrator

1. Download and install the gpmigrator package

   Code Block
   yum localinstall http://user:passwd@mirror.abiquo.com/el7/6.2/os/x86_64/abiquo-gpmigrator-6.2.0-20240205_155724.el7.noarch.rpm

2. Run the tool to migrate the guest passwords of the current VMs to a new column that will be added in 6.2.0.

   1. The tool requires access to the kinton database and to the API Redis

   2. Usage:

      Code Block
      --jdbc-url VAL : Replace VAL with Kinton JDBC URL including user and password --output-file VAL : Replace VAL with the output file (by default: 'guestpasswords.sql') --redis-host VAL : Redis host to connect --redis-port N : Redis port to connect (by default: 6379)

      For example:

      Code Block
      java -jar gpmigrator.jar --jdbc-url="jdbc:mariadb://localhost:3306/kinton?user=root&password=root" --redis-host=localhost

3. Save the guestpasswords.sql file (or whatever you called it) to run after you update the Abiquo database

...

12. Upgrade MariaDB for Abiquo 6.2.0

1. On all database servers, including the Watchtower server, upgrade MariaDB

   Code Block
   rpm --nodeps -ev MariaDB-server-10.4.10-1.el7.centos.x86_64 yum install MariaDB-server service mariadb start # OR for datanode: galera_new_cluster mysql_upgrade

...

13. 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 database 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

   Clear the checksums and run the update again

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

4. For Abiquo 6.2.0, run the gpmigrator SQL file output (with the appropriate user and credentials)

   Code Block
   mysql kinton < guestpasswords.sql

5. To upgrade the Abiquo Watchtower database, for the monitoring appliance, run the command below:

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

...

...

14. Upgrade additional elements

For every version, on EVERY Remote Services servers, update the Redis database script with the new VM definitions.

...

1. On the Abiquo API Server, edit /opt/abiquo/tomcat/conf/Catalina/localhost/api.xml

2. The latest version of the file should contain new options as shown below.
   Update the file and/or variables marked with ${} for your environment.

   Code Block

   <Context> <Resource name="jdbc/abiquoDB" auth="Container" type="javax.sql.DataSource" factory="com.zaxxer.hikari.HikariJNDIFactory" dataSourceClassName="org.mariadb.jdbc.MariaDbDataSource" connectionTimeout="120000" maximumPoolSize="100" username="${server.database.username}" password="${server.database.password}" dataSource.url="jdbc:mariadb://${server.database.host}:${server.database.port}/kinton" /> </Context>

3. If you have a DB cluster, change the datasource.url to point to your Galera cluster.
   This will not affect the multi-master configuration of the cluster

   Code Block
   jdbc:mariadb:loadbalance://address=(host=${DBMAIN})(port=3306)(type=master), address=(host=${DBR1})(port=3306)(type=slave), address=(host=${DBR2})(port=3306)(type=slave)/kinton

4. On the Watchtower server, edit the emmett.conf and delorean.conf files at:

   Code Block
   /etc/abiquo/watchtower/delorean.conf /etc/abiquo/watchtower/emmett.conf

   1. From the connection details, remove jdbc:mysql: and replace with jdbc:mariadb:

   2. Add your Galera configuration if your monitoring DB is in a cluster

...

15. 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 and Changes to UI configuration
   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. Abiquo 6.2.0 updates Java and other packages, so restore your certificates. To do this, you can follow the steps at Update certificates in your Abiquo environment.

...

...

16. Start Abiquo server and services

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