$netstat –tuanp (default port is 5432)

If yes, stop it:

# /etc/init.d/postgresql stop

config metedataserver:

# config-gfarm –p 5432 (-t : check configuration before do it truly)

Create shared secret key for Admin account in home directory(this case:/home/dodo/):

$ gfkey –f –p 31536000

Create an account for communication between server node and file node in security:

#adduser –gecos ‘Gfarm gfsd’ _gfarmfs --force-badname

(password is null)

Create a shared secret key for _gfarmfs user in home directory:

# su _gfarmfs

$ gfkey –f –p 31536000

Config File Node

Create an account for communication between server node and file node in security.

#adduser –gecos ‘Gfarm gfsd’ _gfarmfs --force-badname

(password is must)

Copy the shared secret keys for Admin account from MD Node to the same home directory in SD Node.

Copy the shared secret keys for _ gfarmfs account from MD Node to the same home directory in SD Node.

Copy the file etc/gfarm2.conf from MD Node to the same directory in SD Node.

$config-gfsd (-t for check the configuration before doing truely)

Using admin_user of GFarm on Server Node to register File Node

$su dodo

$ gfhost -c -a i386-centos3.8-linux -p 600 -n 2 kent

Then change to root user and setup gfsd service

#/etc/init.d/gfsd start
