Some of the labs available in the Cumulus Workbench include hosts in addition to the Cumulus Linux switches. You may be required to run VMware software on them. This article describes how to install ESXi and vCenter Server Appliance (VCSA).
You will install ESXi on server1 and server2, exit maintenance mode on both and then deploy a VCSA guest on server1.
To connect to the VCSA, you'll use OpenVPN from outside the Cumulus Workbench.
From the workbench, update the APT cache:
[email protected]:~$ sudo apt-get update
Install the ESXi operating system installer package:
[email protected]:~$ sudo apt-get install cldemo-wbench-osinstaller-vmwareesxi55
The package will:
- Set up a TFTP server on the workbench VM.
- Configure PXELinux to network boot the hosts.
- Extract the ESXi CD to the TFTP directory.
- Add a kickstart file to automate the ESXi installation.
ovftoolon the workbench VM.
To install ESXi on server1, run:
[email protected]:~$ sudo cwng-pxehelper -s server1 -o esxi55 -n
* Copied PXELinux config for server1 / 01-00-25-90-2c-bd-30 * Attempting IPMI (192.168.0.3) PXE first and reboot * Power is on, setting PXE boot and power cycling
Next, to install ESXi on server2, run:
[email protected]:~$ sudo cwng-pxehelper -s server2 -o esxi55 -n
* Copied PXELinux config for server1 / 01-00-25-90-2c-bd-36 * Attempting IPMI (192.168.0.4) PXE first and reboot * Power is on, setting PXE boot and power cycling
Once it's installed, the default username for ESXi is root and default password is password.
Exiting Maintenance Mode
After ESXi has been installed on the hosts, they will be left in maintenance mode. To exit this mode, SSH to each of the servers from the workbench VM and run the following commands:
[email protected]:~$ ssh [email protected]
~ # esxcli system maintenanceMode set --enable false
~ # exit [email protected]:~$
Repeat these commands for server2.
Installing a VCSA
From the workbench, you can deploy a vCentre Server Appliance (VCSA) easily.
ovftool, push the VCSA
ova file for the workbench mirror Web server to server1:
[email protected]:~$ ovftool --noSSLVerify --powerOn http://mirror.cwb.cumulusnetworks.com/vmware/vcsa-5.5.0.ova "vi://root:[email protected]/"
This starts the deployment:
Opening OVA source: http://mirror.cwb.cumulusnetworks.com/vmware/vcsa-5.5.0.ova
The manifest validates
Source is signed and the certificate validates
Opening VI target: vi://[email protected]:443/
Deploying to VI: vi://[email protected]:443/
Powering on VM: VMware-vCenter-Server-Appliance-126.96.36.19900-2183109_OVF10
Finding the IP Address of the New VCSA
Search the workbench
syslog to find the IP address of the new VCSA appliance:
[email protected]:~$ sudo grep -i 00:0c:29 /var/log/syslog
Oct 20 17:10:47 wbench-vm-406 dhcpd: DHCPREQUEST for 192.168.0.102 from 00:0c:29:a2:2b:59 via eth1
Oct 20 17:10:47 wbench-vm-406 dhcpd: DHCPACK on 192.168.0.102 to 00:0c:29:a2:2b:59 (localhost) via eth1
Oct 20 17:45:39 wbench dhcpd: DHCPDISCOVER from 00:0c:29:40:b1:2a via eth1
Oct 20 17:45:40 wbench dhcpd: DHCPOFFER on 192.168.0.103 to 00:0c:29:40:b1:2a (localhost) via eth1
Oct 20 17:45:40 wbench dhcpd: DHCPREQUEST for 192.168.0.103 (192.168.0.1) from 00:0c:29:40:b1:2a (localhost) via eth1
Oct 20 17:45:40 wbench dhcpd: DHCPACK on 192.168.0.103 to 00:0c:29:40:b1:2a (localhost) via eth1
192.168.0.103 has been allocated.
Note: The MAC address of the VCSA appliance will always include 00:0c:29, as that is the range assigned for VMware virtual machines.
Connecting to the Lab with OpenVPN(recommended)
To connect to the VCSA from outside the workbench, you need to establish a tunnel using OpenVPN.
First, you need to install OpenVPN on the workbench. To do so, run:
[email protected]:~$ sudo apt-get install cldemo-wbench-openvpn
At the end of the installation, a URL is displayed, showing the location from which you will download the OpenVPN client configuration files. Also displayed are the username and password required to authenticate with the download site.
Follow the instructions on how to set up your OpenVPN client in the Cumulus workbench.
Accessing the VCSA with OpenVPN
After connecting to the workbench using OpenVPN, point your Web browser at the IP discovered above in the syslog. Continuing with our example above, it is https://192.168.0.103:5480.
Enter the default VCSA credentials:
- Username: root
- Password: vmware
SSH access method
You can also use SSH port forwarding to access the workbench. You will need your workbench ssh port(this can be found in /var/www/wbench.json and replace the NNNN in the example) and the VCSA IP (as described above).
ssh -L 5480:192.168.0.100:5480 -L 9443:192.168.0.100:9443 -p NNNN [email protected]
Replace all instances of
https://192.168.0.103 in the following examples with
https://127.0.0.1. Use the same ports as in the examples.
Setting up the VCSA
By accepting the EULA, the VCSA installer runs through the initial setup; you can skip the customer experience program section. At the Configure Options section, choose the default settings and click Next.
After selecting the default settings it will skip the through the next sections. To complete the installation click Start.
This initiates the default installation of vCenter. When the installer finishes, you will see the finished status below. Click Close to exit the installer.
After the installer closes, the VCSA Summary page appears. From this page you can stop/start services and perform administrative tasks on the underlying vCenter appliance.
Logging into vCenter
To log in to vCenter, point your Web browser at the IP address discovered above in the following URL: https://192.168.0.103:9443/vsphere-client/
Enter the default vCenter credentials:
- Username: root
- Password: vmware
Once you are logged in, follow the wizard to begin adding data centers and hosts. You can also jump directly to the vCenter->Data center section.
Create a default data center into which you will assign the host servers.
Enter a name for the new data center or be creative and use the default like this example.
Once the data center is created, select it and then click Add a host.
The servers server1 and server2 are set up on the DNS server (192.168.0.1), so in the Host name or IP address field you can enter their hostnames, then click Next.
The login credentials are:
- Username: root
- Password: password
Install the host key for the servers by clicking Yes when you receive this security alert.
The next screen displays the host summary.
There are no license keys installed as this is a demonstration system. Choose No License Key and select Next.
You can optionally enable lockdown mode. In this example it is not enabled.
Select the data center and add the host to it. If you created multiple data centers, you can assign the hosts among any or all of them.
Once you are finished, review the summary. If you are satisfied, click Finish.
Repeat this section to add server2 to the inventory.
