Enabling RSH on Compute Nodes

1. SSH 및 RSH 접속 확인

icluster] # ssh compute-0-0

Rocks Compute Node

Rocks 6.0 (Mamba)

Profile built 00:32 06-Jun-2012

Kickstarted 02:28 03-Jul-2012

compute-0-0] # exit

icluster] # rsh compute-0-0

compute-0-0.local: Connection refused

2. 노드 RSH 서버 설정

2.1 Enabling RSH on Compute Nodes(All nodes)

icluster] # rocks set appliance attr compute rsh true 

icluster] # rocks list appliance attr | grep rsh

compute:                 rsh                  true

2.2 Enabling RSH on Compute Nodes(compute-0-0)

icluster] # rocks set host attr compute-0-0 rsh true 

icluster] # rocks list host attr compute-0-0 | grep -w rsh

compute-0-0: rsh                               true                         A

3. rsh server 추가 설치 및 설정

icluster] # yum install --enablerepo=base rsh-server

icluster] # cd /export/rocks/install/contrib/6.0/x86_64/RPMS/

icluster] # cp /var/cache/yum/base/packages/* .

icluster] # ls

rsh-server-0.17-60.el6.x86_64.rpm

icluster] # cd /export/rocks/install/site-profiles/6.0/nodes/

icluster] # cp skeleton.xml extend-compute.xml

icluster] # vi extend-compute.xml

<package>rsh-server</package>

icluster] cd /export/rocks/install

icluster] rocks create distro

4. Reinstall all your compute nodes
