Important:
To avoid performance degradation of the cluster, an external load balancer is recommended
for clusters with four or more nodes.
After installing an initial node, use this procedure to create a cluster of Avaya Aura
®
Web Gateway
nodes. You can also use this procedure to add nodes to an existing cluster at a later time.
Before you begin
• Install an initial Avaya Aura
®
Web Gateway node. For more information, see
on page 64.
• Enable the virtual IP configuration on the initial node if you are using the internal load
balancer for the cluster.
• Configure the front-end FQDN on the initial node to match the FQDN assigned to the load
balancer. If you need to update the front-end FQDN on the initial node, use the configuration
utility.
• Deploy an OVA on the same network as the initial node for each additional node required.
For more information, see
on page 43.
Procedure
1. Open the Linux shell using your Linux administrator account credentials.
The Linux administrator account is created during the deployment process.
2. To install the Avaya Aura
®
Web Gateway, run the following command:
app install
When you run the
app install
command without specifying a build, then the system
automatically picks up the current build in
opt/Avaya
. If you do specify a build by running
app install csa-<version>.bin
, then the system looks for that build first in your
current working directory and then in
opt/Avaya
.
The system displays the installation screen.
Important:
During the installation, do not resize the screen or the SSH console.
3. Select
Cluster Configuration
and do the following:
a. Set the
Initial cluster node
option to
n
(no).
b. Ensure that
Local Node IP address
is set to the IP address of the current node.
c. Set
Cluster seed node
to the IP address of the initial node.
d. Set
User ID (UID) of product user on seed node
to the user ID of the Linux
administrator that was used to install the initial Avaya Aura
®
Web Gateway node.
The default value is 4000.
To determine the required UID, open the Linux shell on the initial node using your
administrator credentials and then run the following command:
id -u <adminuser>
