Install the NetQ Cloud Appliance Cluster

This topic describes how to prepare your cluster of NetQ Cloud Appliances for installation of the NetQ software.

Inside each box that was shipped to you, you’ll find:

A Cumulus NetQ Cloud Appliance (a Supermicro SuperServer E300-9D)
Hardware accessories, such as power cables and rack mounting gear (note that network cables and optics ship separately)
Information regarding your order

For more detail about hardware specifications (including LED layouts and FRUs like the power supply or fans and accessories like included cables) or safety and environmental information, check out the appliance’s user manual.

Install Each Appliance

After you unbox the appliance:

Mount the appliance in the rack.
Connect it to power following the procedures described in your appliance's user manual.
Connect the Ethernet cable to the 1G management port (eno1).
Power on the appliance.

If your network runs DHCP, you can configure NetQ over the network. If DHCP is not enabled, then you configure the appliance using the console cable provided.

Configure the Password, Hostname and IP Address

Change the password and specify the hostname and IP address for each appliance before installing the NetQ software.

Log in to the appliance that will be your master node using the default login credentials:
- Username: cumulus
- Password: CumulusLinux!

Change the password using the passwd command:

cumulus@hostname:~$ passwd
Changing password for <user>.
(current) UNIX password:
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully

The default hostname for the NetQ Cloud Appliance is netq-appliance. Change the hostname to fit your naming conventions using the following command:
```
cumulus@hostname:~$ sudo hostnamectl set-hostname NEW_HOSTNAME
```
Identify the IP address.

The appliance contains two Ethernet ports. Port eno1, is dedicated for out-of-band management. This is where NetQ Agents should send the telemetry data collected from your monitored switches and hosts. By default, eno1 uses DHCPv4 to get its IP address. You can view the assigned IP address using the following command:
```
cumulus@hostname:~$ ip -4 -brief addr show eno1
eno1             UP             10.20.16.248/24
```
Alternately, you can configure the interface with a static IP address by editing the /etc/netplan/01-ethernet.yaml Ubuntu Netplan configuration file.

For example, to set your network interface eno1 to a static IP address of 192.168.1.222 with gateway 192.168.1.1 and DNS server as 8.8.8.8 and 8.8.4.4:
```
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
    version: 2
    renderer: networkd
    ethernets:
        eno1:
            dhcp4: no
            addresses: [192.168.1.222/24]
            gateway4: 192.168.1.1
            nameservers:
                addresses: [8.8.8.8,8.8.4.4]
```
Apply the settings.
```
cumulus@hostname:~$ sudo netplan apply
```
Repeat these steps for each of the worker node appliances.

Verify NetQ Software and Appliance Readiness

Now that the appliances are up and running, verify that the software is available and each appliance is ready for installation.

On the master NetQ Cloud Appliance, verify that the needed packages are present and of the correct release, version 2.4.1 and update 26 or later.

cumulus@hostname:~$ dpkg -l | grep netq
ii  netq-agent   2.4.1-ub18.04u26~1581351889.c5ec3e5 amd64   Cumulus NetQ Telemetry Agent for Ubuntu
ii  netq-apps    2.4.1-ub18.04u26~1581351889.c5ec3e5 amd64   Cumulus NetQ Fabric Validation Application for Ubuntu

Verify the installation images are present and of the correct release, version 2.4.1.

cumulus@hostname:~$ cd /mnt/installables/
cumulus@hostname:/mnt/installables$ ls
NetQ-2.4.1-opta.tgz  netq-bootstrap-2.4.1.tgz

Verify the master NetQ Cloud Appliance is ready for installation. Fix any errors indicated before installing the NetQ software.
```
cumulus@hostname:~$ sudo opta-check-cloud
```
Run the Bootstrap CLI. Be sure to replace the eno1 interface used in this example with the interface or IP address on the appliance used to listen for NetQ Agents.
```
cumulus@:~$ netq bootstrap master interface eno1 tarball /mnt/installables/netq-bootstrap-2.4.1.tgz
```
Allow about five to ten minutes for this to complete, and only then continue to the next step.
If this step fails for any reason, you can run netq bootstrap reset and then try again.
If you have changed the IP address or hostname of the NetQ Cloud Appliance after this step, you need to re-register this address with NetQ as follows:

Reset the appliance.
```
cumulus@hostname:~$ netq bootstrap reset
```
Re-run the Bootstrap CLI on the appliance. This example uses interface eno1. Replace this with your updated IP address, hostname or interface using the interface or ip-addr option.
```
cumulus@:~$ netq bootstrap master interface eno1 tarball /mnt/installables/netq-bootstrap-2.4.1.tgz
```

On one of your worker NetQ Cloud Appliances, verify that the needed packages are present and of the correct release, version 2.4.1 and update 26 or later.

cumulus@hostname:~$ dpkg -l | grep netq
ii  netq-agent   2.4.1-ub18.04u26~1581351889.c5ec3e5 amd64   Cumulus NetQ Telemetry Agent for Ubuntu
ii  netq-apps    2.4.1-ub18.04u26~1581351889.c5ec3e5 amd64   Cumulus NetQ Fabric Validation Application for Ubuntu

Configure the IP address, hostname, and password using the same steps as as for the master node. Refer to Configure the Password, Hostname, and IP Address.

Make a note of the private IP addresses you assign to the master and worker nodes. They are needed for the later installation steps.

Verify that the needed packages are present and of the correct release, version 2.4.1 and update 26 or later.

cumulus@hostname:~$ dpkg -l | grep netq
ii  netq-agent   2.4.1-ub18.04u26~1581351889.c5ec3e5 amd64   Cumulus NetQ Telemetry Agent for Ubuntu
ii  netq-apps    2.4.1-ub18.04u26~1581351889.c5ec3e5 amd64   Cumulus NetQ Fabric Validation Application for Ubuntu

Verify that the needed files are present and of the correct release.

cumulus@hostname:~$ cd /mnt/installables/
cumulus@hostname:/mnt/installables$ ls
NetQ-2.4.1-opta.tgz  netq-bootstrap-2.4.1.tgz

Verify the platform is ready for installation. Fix any errors indicated before installing the NetQ software.
```
cumulus@hostname:~$ sudo opta-check-cloud
```
Run the Bootstrap CLI on the worker node.
```
cumulus@:~$ netq bootstrap worker tarball /mnt/installables/netq-bootstrap-2.4.1.tgz master-ip <master-ip> [password <text-password>]
```
Allow about five to ten minutes for this to complete, and only then continue to the next step.
If this step fails for any reason, you can run netq bootstrap reset on the new worker node and then try again.
Repeat Steps 5-10 for each additional worker NetQ Cloud Appliance.

The final step is to install and activate the Cumulus NetQ software on each appliance in your cluster. You can do this using the Admin UI or the CLI.

Click the installation and activation method you want to use to complete installation:

Use the Admin UI (recommended)
Use the CLI

Install the NetQ Cloud Appliance Cluster

Install Each Appliance

Configure the Password, Hostname and IP Address
