There is very little changes in the Vagrantfile. DB2 installation is done via db2_install.sh

• Vagrantfile has a line for private network, it uses DHCP for assigning IP address, you can update it to suit your needs

Steps

• Download v11.1_linuxx64_expc.tar.gz from IBM DB2
  • Make sure update the name of db2 installation file in db2_install.sh
• Place the installation package at the same dir as db2_install.sh
• On host system, cd db2 then run vagrant up
• SSH into vagrant box using vagrant ssh
• We need to disable SELINUX or set it to permissive mode otherwise DB2 installation will show error. So switch to root with sudo su -, then run sed -i "s/SELINUX=enforcing.*/SELINUX=permissive/g" /etc/selinux/config; reboot, this will change selinux to permissive mode and reboot the system to make change to SELINUX take effect
• Once the system is come back up, run sudo sh /vagrant/db2_install.sh, this will install db2 and db2 dependences
  • db2 username: db2inst1
  • password: passw0rd
• Switch to db2inst1 user with su - db2inst1, then run db2start will start the db2
