How to move Dualshield to another machine on Linux

On the existing machine

• Stop services

sudo /etc/init.d/dualshield stop
sudo /etc/init.d/dualsql stop

• Create a working directory

mkdir dualshield-files

• Enter the working directory

cd dualshield-files

• Compress the whole installation folder

sudo tar -C /opt -czf dualshield.tar.gz dualshield

• Copy service scripts

cp /etc/init.d/dualshield .
cp /etc/init.d/dualsql .

• Copy all files to the new machine

scp -r /path/to/dualshield-files someuser@remote.server:/somepath/

On the new machine

cd dualshield-files

• Extract dualshield folder

sudo tar -xzvf dualshield.tar.gz -C /opt/

• Copy service script

sudo useradd -g dualshield -s /sbin/nologin dualshield

• Change dualshield directory owner

sudo chown -R dualshield:dualshield /opt/dualshield

• Add host file entries
  (replace dualshield.fqdn.com with your actual dualshield fqdn)

sudo echo "127.0.0.1    dualshield.fqdn.com" >> /etc/hosts
sudo echo "127.0.0.1    $(hostname)" >> /etc/hosts

• Register services

# if you are on RHEL, CentOS, Fedora, Rocky etc
sudo /sbin/chkconfig --add dualshield
sudo /sbin/chkconfig --add dualsql

# if you are on ubuntu, debian etc
sudo update-rc.d dualshield defaults 89
sudo update-rc.d dualsql defaults 88
