Cluster: New BobSCEd Install Log

Scratch Space

Green color indicates something that still needs to be done.

Yum installed:

gcc.x86_64
for Ganglia:
- apr.x86_64 and apr-devel.x86_64
- libconfuse-2.5-4.el5.x86_64.rpm, libconfuse-devel-2.5-4.el5.x86_64.rpm (from Fedora repositories)
- expat-devel.x86_64

Install C3 tools from http://www.csm.ornl.gov/torc/C3/C3softwarepage.shtml

Downloaded full install rpm on bs0, installed with yum --nogpgcheck localinstall c3-4.0.1-1.noarch.rpm
- See C3 Tools README and C3 Tools INSTALL
- Put root's keys in the home directory and authorized itself, then copied that to the worker node image

Ganglia

On hopper, added the data_source line for bs0 to /usr/local/etc/gmetad.conf and restarted it with /usr/local/etc/rc.d/gmetad restart
Downloaded tar ball from http://sourceforge.net/projects/ganglia/
- See Ganglia README
- ./configure --prefix=/cluster
- It looks for the config in /etc/ganglia/gmond.conf, so I symlinked to there from /etc/cluster/gmond.conf
- Configured ACLs (see gmond man page)
- By default, iptables is running on the CentOS install and blocks hopper's Ganglia requests
  - For now, disabled iptables - needs to be further looked into

Shorewall, see /etc/shorewall/params for almost all of the important definitions
- Natting is done through /etc/shorewall/masq

DHCP relay, added to boot with chkconfig on, set for hopper (installed as part of dhcp yum package)
- See /etc/sysconfig/dhcrelay
- This means that a dhcp server is also installed, but it is not set to run and is not configured, either
- Hopper needs to have a static route added in order to have the responses return, these are in /etc/rc.conf:

static_routes="bs0"

route_bs0="192.168.0.1 159.28.234.200"
