Add roll on an existing server

이미 설치된 Cluster 에 Roll을 추가하는 방법입니다.
아래 설명은 Area51 매뉴얼이지만,, 대부분의 roll cd에 적용 가능합니다.

2.2. On an Existing Server

The area51 Roll may also be added onto an existing server (or frontend). For sake of discussion, assume that you have an iso image of the roll called area51.iso. The following procedure will install the Roll, and after the server reboots the Roll should be fully installed and configured.

$ su - root

# rocks add roll area51.iso

# rocks enable roll area51

# cd /export/rocks/install

# rocks create distro

# rocks run roll area51 | bash

# init 6
