Editing CODA Setup (section)

====STEP 8: NFS (Export the file systems from jlabdaq to jlabvme)====

i.	Open a new shell (terminal)

ii.	$ su

iii.	$ <root password>

iv.	# vi /etc/exports

<span style="color:green">'''Link:''' [[Setup Files#Exports File|Exports File]]</span>

<span style="color:blue">'''Hint:''' This is a CNU network configuration.</span> 

v.	Edit this file by adding these lines:

    1.	/home 137.155.2.0/255.255.255.0(rw,sync,no_root_squash)
    2.	/usr/local/coda 137.155.2.0/255.255.255.0(rw,sync,no_root_squash)
    3.	/usr/lib/jvm 137.155.2.0/255.255.255.0(rw,sync,no_root_squash)

vi.	Save and exit the file

vii.	<span style="color:blue">'''Hint:''' start NFS while super user</span> 

viii.	# /sbin/chkconfig --levels 345 nfs on

ix.	Check if NFS is on: # /sbin/chkconfig --list nfs status

x.	# /etc/init.d/nfs start

xi.	# exit

xii.	ssh into jlabvme: $ ssh root@jlabvme

xiii.	# vi /etc/fstab

<span style="color:green">'''Link:''' [[Setup Files#fstab File|fstab File]]</span>

xiv.	Add these lines in preparation for mounting

    1.    jlabdaq:/home                 /daqhome           nfs            rw,sync       0 0
    2.    jlabdaq:/usr/local/coda      /usr/local/coda    nfs            defaults       0 0
    3.    jlabdaq:/usr/lib/jvm       /usr/lib/jvm         nfs            defaults       0 0

xv.	Make the directories that were specified above

    1.    # mkdir /daqhome
    2.    # mkdir /usr/local/coda
    3.    # mkdir /usr/lib/jvm

xvi.	# mount –a

xvii.	Proper sourcing in jlabvme

    1.    Create a new environment variable file on jlabvme that has the NFS mounted directories. (We named ours coda_Luter345)  
    2.    <span style="color:green">'''Link:''' [[Setup Files#Environment Variables On jlabvme (coda_Luter345)|Environment Variables On jlabvme (coda_Luter345)]]</span>
    3.    Once the the environment variables are set, they must be sourced
    4.    Create a new script that sources coda_Luter345 (We named ours setLuter345.sh)
    5.    <span style="color:green">'''Link:''' [[Setup Files#setLuter345.sh|setLuter345.sh]]</span>
