listening for all communication on the well-known IP addresses for the internal and external network.

When a secondary CSN joins the internal network, it registers with the primary CSN via a privileged

SSH channel using the primary root password entered during the initial configuration process. This

allows the primary to sync needed information to the secondary, specifically the Primary's Backup

Manifest UUID. The secondary CSN provides redundancy for all services on the primary CSN in the

event of a disaster and also provides scalability for incoming SCSP requests to the SCSP Proxy.

2.3. Installation Steps

The CSN distribution is available as a collection of RPM packages that are installed with a shell

script. The packages and their dependencies must be installed as the 'root' user from an attached

monitor and keyboard with at least one NIC connected to the external network using the following

steps. Please reference the Upgrade section for additional steps required for upgrading the

software:

1. Copy the distributed zip file to your Cluster Services Node and unzip it into the directory of your

choice. The following example command would unzip the version of the software which was

previously copied to the /tmp/csninstall directory:

$ sudo su -

# cd /tmp/csninstall

# unzip caringo-csn-2.0.0.zip

Note

The full zip name may include additional descriptive labeling related to versions or

distribution channel depending on how the CSN software release is delivered.

2. Install the CSN by running the self-extracting script from the directory location where the shell

script was unzipped. For instance, continuing the example above from the /tmp/csninstall

directory:

# cd caringo-csn-2.0.0

# ./caringo-csn-bundle-install.sh

This command will initiate installation of the CSN and its dependent packages. When the

installation is complete, the following prompt will display:

Would you like to proceed with CSN network configuration? (yes/no):

Answer 'yes' to proceed with configuring the CSN. If you answer 'no', you may return to the

configuration screen at a later time by running the command: /opt/caringo/csn/bin/

firstcsnboot.

If you run the configuration at a later time, it must still be from an attached monitor and keyboard.

After installing the CSN, you will automatically be prompted to enter some minimal configuration

data to configure the server on the overall network. Network settings are central to all CSN

services and should be planned with care in advance by an administrator knowledgeable about the

environment. The initial configuration process is only required once after the initial installation. Any

necessary subsequent updates to the initial configuration parameters can be made from the CSN

Console.
