3. Prevent cloud users from performing VM operations

...

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.

5. Back up the main platform elements

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

...

6. 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. Stop remote services server

   Code Block
   systemctl stop abiquo-tomcat

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

5. Stop monitoring server

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

6. 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.

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 WatchtowerMySQL DBDBs
mysqldump --routines --triggers watchtowerkinton            > watchtowerkinton.sql-$(date +%Y%m%d_%H%M%S)
mysqldump --routines --triggers kinton_accounting # On the Abiquo API Server or UI> kinton_accounting.sql-$(date +%Y%m%d_%H%M%S)

# On the Monitoring server, back up theWatchtower UIDB
tarmysqldump cvfz /var/www/html/ui.tgz---routines --triggers watchtower            > watchtower.sql-$(date +%Y%m%d_%H%M%S) /var/www/html/ui
