Changing a BlueMind Server's IP Address

This page describes how to change a BlueMind server's IP address.

Caution

This description is deliberately minimal as it is reserved to experienced administrators who are familiar with the sensitive operations performed.

Procedure​

  • Stop BlueMind using the command:
bmctl stop
  • Start postgresql:
systemctl start postgresql
  • Update the server's network configuration with the new IP address
  • Edit the file /etc/bm/bm.ini, replacing the address of the "host" and "hz-member-address" parameters with the new IP address
  • Update the database information with the following command line:
sudo -u postgres -i psql -h localhost -U bj -d bj -W -c "update t_server set ip = '<new_ip>' where ip = '<old_ip>';"
sudo -u postgres -i psql -h localhost -U bj -d bj -W -c "update t_systemconf set configuration = configuration || hstore('host','<new_ip>') || hstore('hz-member-address', '<new_ip>');"

Where:

  • <old_ip> is the previous IP

  • <new_ip> is the new IP

Note: if prompted for a password, type "bj"

  • Edit the /var/backups/bluemind folder structure, renaming the folder /var/backups/bluemind/dp_spool/rsync/<old_ip> with the new IP address
  • Restart BlueMind and the node using the following commands:
bmctl start
systemctl restart bm-node
  • Log into the administration panel superadministrator admin0
  • Go to Security > Manage firewall and click "Save" to force re-generate BlueMind's firewall rules
  • Go to System Management > Manage Messaging System, click "Execute" to regenerate the postfix mail routing table
  • Go to System Management > System Configuration > Mail and replace the old IP address in the field "My networks" by the new address of the address range you want to keep as open relay. Click "Save".
  • Reconfigure tick using the following command:
kapacitor list tasks |  awk '{print $1}' | grep -v ID | xargs -I {} kapacitor delete tasks {}
bm-cli tick reconfigure
