Created GNIS page for integrating new servers/VMs into samba environment.

New page

Basic steps for adding a system to our samba environment. Currently configured for CentOS and similar systems.

==Install Process==
*Useful link with additional information: http://wiki.eri.ucsb.edu/sysadm/Yum#Autofs:

If you have trouble accessing repos, check DNS at /etc/resolve.conf
[root@server ~]# yum install autofs nfs-utils -y

===/etc/auto.*===
[root@server ~]# vib /etc/auto.master
Copy the last two lines found in ubu's auto.master and add them to the bottom of the "new" server's auto.master
/- /etc/auto.eri --timeout=300
/home /etc/auto.home --timeout=300
Copy over the /etc/auto.eri and /etc/auto.home from ubu
[root@server ~]# scp root@ubu:/etc/auto.eri /etc/
[root@server ~]# scp root@ubu:/etc/auto.home /etc/
[root@server ~]# modprobe nfsd
[root@server ~]# service rpcbind start
[root@server ~]# service nfslock start # May or may not be needed
[root@server ~]# service netfs start
[root@server ~]# service autofs start

===/etc/exports===
On ubu, add the IP for the "new" server to the listings in /etc/exports:
*make sure it's got the no_root_squash flag included
*mimic other entries in that file
*Place entry in numerical order, be careful because ORDER MATTERS (you can bust all sorts of stuff/systems at this point given all the systems that depend on NFS exports from ubu/rain. Rules in that file are met in order - if a rule is met it drops out, so you need to put the '''no_root_squash''' entries at the beginning in case a wild-card type entry not allowing no_root_squash comes up so it doesn't override what you're trying to do).

Re-export the stuff from ubu
[root@ubu ~]# exportfs -farv #The flush and reexport cleans up local tables and such better, leaving less likelihood if residual issues.

===Pull Script===
Back on the "new" server, GNIS is completed using a custom ERI script to pull the automounts over.
[root@server etc]# /home/sysadm/bin/pull-conf.C6-now 2
backin up and updating /etc/passwd omitting 1st 2 lines...
backin up and updating /etc/shadow omitting 1st 2 lines...
backin up and updating /etc/group omitting 1st 2 lines...
backin up and updating /etc/gshadow omitting 1st 2 lines...

==Notes==
*Currently working on finding a solution for auto-mounting in Ubuntu. Can't use the ERI pull-conf.C6 script because the /etc files are too different in Ubuntu (was set up for Red Hat/CentOS and Ubuntu doesn't have a "root", etc) [[User:Libby|Libby]] 13:22, 17 March 2015 (PDT)
