Milestone 7.1 Ansibilizing centOS - absentee-neptune/SYS-480 GitHub Wiki

Deploying centOS 1-3

• Using cloner.ps1 and cloner.json from Milestone 6, deploy three linked clones of centOS.7.base on the BLUE8_LAN network
• links to files:
  • cloner.ps1
  • cloner.json

Getting the IP Addresses

• Using the getIP() function created in utility.ps1, get the IPs of the deployed centOS systems, and put them in an Ansible file under [centos_server]. This is so that, using ansible, we can check the connection by pinging the three systems.
  • command to ping systems using Ansible:
    • ansible centos_server -m ping -i ansible_provision_7.txt -u deployer --ask-pass
• links to files:
  • utility.ps1
  • ansible_provision_7.txt

Checking the DHCP Leases

• ssh into fw-blue8 to review the DHCP service:
  • show dhcp server statistics
  • show dhcp server leases

Ansible Scripts

Make sure the apropriate IP addresses are added to the Ansible Provisioning files for the appropriate connection

• Two Ansible Scripts are to be created:
  • One to push the public key of xubuntu-wan to the deployed centOS machines to allow password-less log-ins
    • push-public-key.yml
    • ansible_provision_7.txt
    • command to use the script:
      • ansible-playbook -i ./ansible_provision_7.txt -u deployer -K --ask-pass push-public-key.yml
  • Another to change the network settings of the deployed centOS machines to static IP addresses using the proper configurations
    • ifcfg-script.j2
    • centos-networking.yml
    • ansible_provision_7_networking.txt
    • command to use the script:
      • ansible-playbook -i ./ansible_provision_7_networking.txt -u deployer -K --ask-pass centos-networking.yml
