Register the Walrus Backend

This topic describes how to register the Walrus Backend service with the Cloud Controller (CLC).

Prerequisites

To register the Walrus Backend service with the Eucalyptus cloud

Note: This task is not necessary if you are using Riak CS instead of Walrus.

On the CLC host machine, run the following command:
```
euserv-register-service -t walrusbackend -h IP SVCINSTANCE
```
where:
- IP is the IP of the Walrus Backend you are registering with this CLC.
- SVCINSTANCE must be a unique name for the Walrus Backend service. We recommend that you use a short-hand name of the hostname or IP address of the machine, for example: walrus-HOSTNAME or walrus-IP_ADDRESS.
For example:
```
euserv-register-service -t walrusbackend -h 10.111.5.182 walrus-10.111.5.182
```
Copy the security credentials from the CLC to each machine running a Walrus Backend service. Run this command on the CLC host machine:
```
clcadmin-copy-keys HOST [HOST ...]
```
For example:
```
clcadmin-copy-keys 10.111.5.182
```
Verify that the Walrus Backend service is registered with the following command:
```
euserv-describe-services SVCINSTANCE
```

The registered Walrus Backend service is now ready for your cloud.
