Restore the Database

To restore the cloud database follow the steps listed in this topic.

Sometimes you’ll get this message on both startup and shutdown of the database: … where is actually your current directory, meaning if you run the command from , then the path in the output will be instead of . The message is completely benign and can be ignored.

To restore the database

Stop the CLC service.

systemctl stop eucalyptus-cloud.service

Remove traces of the old database.

rm -rf /var/lib/eucalyptus/db

Restore the cloud security credentials in the keys directory.

tar -xvf ~/eucalyptus-keydir.tgz -C /

Re-initialize the database structure.


Start the database manually.

su eucalyptus -s /bin/bash -c "/usr/bin/pg_ctl start -w \
-s -D/var/lib/eucalyptus/db/data -o '-h0.0.0.0/0 -p8777 -i'"

Restore the backup.

psql -U root -d postgres -p 8777 -h /var/lib/eucalyptus/db/data -f/root/eucalyptus_pg_dumpall-backup.sql

Stop the database manually.

su eucalyptus -s /bin/bash -c "/usr/bin/pg_ctl stop -D/var/lib/eucalyptus/db/data"

Start CLC service

If you are upgrading, skip this step (you don’t want to start the CLC service now because you haven’t restored the rest of the cloud data yet; starting the CLC appears in the installation steps, later).

systemctl start eucalyptus-cloud.service
