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.

...

9. 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 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)

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 the shared folder from the second step again.

   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.

      For CentOS 7

      Code Block
      EC2_HOME=/opt/aws

...

10. Run the guest password migrator

1. Download and install the guestpasswordmigrator package

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/kintonuser=root&password=root" --redis-host=localhost

3. Save the guestpasswords.sql file and run it after you update the database with abiquo-db.
