Summary Key Takeaways The key takeaways for this exercise are: Exercise 6: Preparing the RHOS setup to install PLUMgrid Overview Before PLUMgrid configuration and packages can be added to a running Redhat OpenStack Cloud some additional modification needs to take place, this include changing the MTU of the network interfaces that connect to the Fabric network (pgmgmt) to 1580, setting SELinux to permissive and stopping the puppet agent Step by step guidance Estimated time to complete this lab: 10 minutes. Page 25

1. SSH or Console to the rhos-controller VM, login with root/plumgrid Run this commands: setenforce 0 Edit the SELinux config

network, edit the ifcfg-eth1 file and add MTU=1580 to the file vi /etc/sysconfig/network-scripts/ifcfg-eth0 Note make sure you

systemctl stop puppet Verify that the MTU change is reflected by running Ifconfig eth0 2.

26 1. SSH or Console to the rhos-controller VM, login with root/plumgrid Run this commands: setenforce 0 Edit the SELinux config file and change the SELINUX value to: permissive vi /etc/selinux/config Change the MTU size of the NIC connected to the pgmgmt network, edit the ifcfg-eth1 file and add MTU=1580 to the file vi /etc/sysconfig/network-scripts/ifcfg-eth0 Note make sure you are changing the correct network interface Restart the network service: systemctl restart network Stop the puppet agent systemctl stop puppet Verify that the MTU change is reflected by running Ifconfig eth0 2. Repeat the same process for the rhos-compute1 node. Note the rhos-compute1 node has 2 network interfaces, we only need to change the one connected to the pgmgmt network Page 26

The lcm VM image has been preloaded to the infrastructure host and can be found at /home/images From your desktop open Virtual Machine Manager and create a new VM 2. Name the VM lcm and use Import existing disk image option Click Forward 3. Browse to /home/images and locate the lcm.qcow2 image and click on it. Set OS Type to: Linux Version: RHEL 6 Click Froward Page 28

Wait for the VM to boot up, once you get the login prompt login in with User: root Password: plumgrid Edit

29 4. Set the Memory (RAM) to 2048 MB and CPUs to: 2 Click Forward 5. Click on Advanced Options and change the selected network to: pgmgmt Click Finish 6. Wait for the VM to boot up, once you get the login prompt login in with User: root Password: plumgrid Edit the network setting by running this command: vi /etc/sysconfig/network-scripts/ifcfg-eth0 Use these values: IPADDR= GATEWAY= DNS1= Page 29

30 7. Save and exit the file. Restart network service by running this command: service network restart Check internet connectivity and name resolution by pinging ping Change the host file by running this command: vi /etc/hosts Delete the 2 lines starting with ::1 and 33.x, add a new line: lcm.mycloud.local lcm Your file should look like this: Edit the hostname by running this command: vi /etc/sysconfig/network Change the hostname to: HOSTNAME=lcm.mycloud.local 8. Reboot the VM and log back in once the VM is up. 9. Update the packages on the VM by running this command: yum update When the upgrade process is complete reboot the VM and log back in once the VM is up. Page 30

31 10. Run this command to start the LCM installer: bash /opt/pg/var/www/files/lvm-installer.sh The LCM Installer wizard will start and will ask you some questions, use these answers: Enter customer name: Customer1 Enter site name: Site1 Is this a RHOS setup? (default [yes]): yes Enter RHEL-OSP Installer IP address: Enter RHEL-OSP Installer admin password: plumgrid The installer will kick off the installation process and you will see a lot on lines running on the screen, this can take 4-5 minutes to complete. The LCM Installer will create a repo site that is used to store PLUMgrid packages, check if the repo is create by opening a new browser windows and navigating to: you should see something like this: 11. LCM Setup in complete. 12. Summary Key Takeaways NOTES The key takeaways for this exercise are: Page 31

38 Exercise 9: Post Setup configurations and initial testing Overview In this exercise will run few port installation configurations and testing of the system. Step by step guidance Estimated time to complete this lab: xx minutes. Step Action 1. PLUMgrid must be in sync with Neutron DB, to make sure this is working OK we will need to delete the default security groups that was present before PLUMgrid was added, not to worry, OpenStack will re-create these groups immediately. To do that follow these steps 2. SSH to the rhos-controller VM, log in as root/plumgrid Run this command: source keystonerc_admin This will load the admin credentials that will be used by the OpenStack CLI client Run this command: neutron security-group-delete `neutron security-group-list grep default cut -f 2 -d' '` 3. Switch to the RHOS Dashboard, login ad admin/plumgrid Click on Project and then click on Access and Security 4. For the Default Security Group click on Manage Rules Page 38

Step Action 5. Click on Add Rule, Add a new rule will the following parameters Rule: All ICMP Direction: Ingress Remote: CIDR CIDR: 0.0.0.0/0 Click Add 6.

Switch Back to the PLUMgrid Management Console, Click on Virtual Domain View and refresh the browser windows, you should see a new Virtual domain created and a new (Still blank)

39 Step Action 5. Click on Add Rule, Add a new rule will the following parameters Rule: All ICMP Direction: Ingress Remote: CIDR CIDR: /0 Click Add 6. If the rule is added successfully than add another rule with the following parameters: Rule: All ICMP Direction: Egress Remote: CIDR CIDR: /0 7. Switch Back to the PLUMgrid Management Console, Click on Virtual Domain View and refresh the browser windows, you should see a new Virtual domain created and a new (Still blank) Neutron-based topology This is an indication that the DB s are in sync 8. Creating an External (Provider) Network - Switch back to RHOS Dashboard and Click on Admin and then click on Networks 9. Click on +Create Network Page 39

40 Step Action 10. Add a New Network using these parameters: Name: External_Network Project: Admin Admin State: Checked External Network: Checked Click Create Network 11. Click on the newly created network and then click on +Create Subnet, Add the new Subnet with these values: Name: External Subnet Network Address: /24 IP Version: IPv4 Gateway IP: Click Next Enable DHCP: Uncheck Allocation pool: , DNS Name Server: Click Create Page 40
