Post je na engleskom posto sam ga napisao za LinuxQuestions forume. Gledacu da sto pre prepravim na srpski.
Originalni post: http://www.linuxquestions.org/questions/fedora-35/about-nfs-automount-814184/#post4003950Primer je radjen na CentOS 5.5 i serveru i klijentu.
I will explain in details how to create NFS4 Server to be used with Automount (autofs) clients.
Server:
Special folder where you will mount/export all of your folders can be placed where ever you want.
My setup has 6 subfolders to export so I will not change anything. You use as much folders you need.Create /nfs4exports with subfolders:
etc, extra, home, ostalo, usr, var.[code]mkdir /nfs4exports; mkdir /nfs4exports/extra; mkdir /nfs4exports/home; mkdir /nfs4exports/etc
mkdir /nfs4exports/ostalo; mkdir /nfs4exports/usr; mkdir /nfs4exports/var[/code]
Put in /etc/fstab:
[code]/extra /nfs4exports/extra bind bind 0 0
/ostalo /nfs4exports/ostalo bind bind 0 0
/etc /nfs4exports/system/etc bind bind 0 0
/home /nfs4exports/system/home bind bind 0 0
/var /nfs4exports/system/var bind bind 0 0
/usr /nfs4exports/system/usr bind bind 0 0[/code]Put in /etc/exports:
[code]/nfs4exports ccc.vvv.219.88/255.255.255.248(rw,fsid=0,sync,no_root_squash,no_subtree_check)
/nfs4exports/extra ccc.vvv.219.88/255.255.255.248(rw,no_subtree_check,nohide,sync,no_root_squash)
/nfs4exports/ostalo ccc.vvv.219.88/255.255.255.248(rw,no_subtree_check,nohide,sync,no_root_squash)
/nfs4exports/system/etc ccc.vvv.219.88/255.255.255.248(rw,no_subtree_check,nohide,sync,no_root_squash)
/nfs4exports/system/home ccc.vvv.219.88/255.255.255.248(rw,no_subtree_check,nohide,sync,no_root_squash)
/nfs4exports/system/usr ccc.vvv.219.88/255.255.255.248(rw,no_subtree_check,nohide,sync,no_root_squash)
/nfs4exports/system/var ccc.vvv.219.88/255.255.255.248(rw,no_subtree_check,nohide,sync,no_root_squash) 192.168.219.0/24(rw,no_subtree_check,nohide,sync,no_root_squash) xx.yyy.208.130(rw,no_subtree_check,nohide,sync)
[/code]
You might want to change some of the options, like “no_root_squash”. Research and decide for your self.
“ccc.vvv” and “xx.yyy” are part of my public IP’sPut in /etc/sysconfig/nfs:
[code]LOCKD_TCPPORT=32803
# UDP port rpc.lockd should listen on.
LOCKD_UDPPORT=32769
RPCNFSDARGS=”-N 2 -N 3″
MOUNTD_PORT=892
STATD_PORT=662
# Outgoing port statd should used. The default is port
# is random
STATD_OUTGOING_PORT=2020
# Specify callout program
[/code]
So you can leave open only ports 32803,32769,892,662,2020 in your firewall. I leave them open only for those selected IP’s./etc/idmapd.conf:
[code][General]Verbosity = 0
Pipefs-Directory = /var/lib/nfs/rpc_pipefs
Domain =[Mapping]
Nobody-User =
Nobody-Group =[Translation]
Method = nsswitch[/code]Domain is necessary to be same on both Server and Clients, user can be left alone.
You MUST have your hostnames sorted out, Server MUST know on what IP he can find the Client that tries to access him. I use DNS Server for that.The last thing is to restart some services. I believe only “nfs” and “portmap” should be restarted:
[code]service portmap restart; service nfs restart[/code]
Client:
To test is NFS4 server is exporting folders and to what IP’s:
test : showmount -eAdd this to /etc/auto.master:
[code]/autofsmounts/kancelarija /etc/auto.kancelarija –timeout=10[/code]“kancelarija” is hostname of my NFS server. “/autofsmounts” is where I chose to place my autofs folders and then create symlinks to the place I want to directly access those folders.
“ccc.vvv.219.92” is IP of my NFS server.Create /etc/auto.kancelarija with:
[code]etc -fstype=nfs4,rw,proto=tcp ccc.vvv.219.92:/etc
extra -fstype=nfs4,rw,proto=tcp ccc.vvv.219.92:/extra
home -fstype=nfs4,rw,proto=tcp ccc.vvv.219.92:/home
ostalo -fstype=nfs4,rw,proto=tcp ccc.vvv.219.92:/ostalo
usr -fstype=nfs4,rw,proto=tcp ccc.vvv.219.92:/usr
var -fstype=nfs4,rw,proto=tcp ccc.vvv.219.92:/var
[/code]/etc/idmapd.conf:
[code][General]Verbosity = 0
Pipefs-Directory = /var/lib/nfs/rpc_pipefs
Domain =[Mapping]
Nobody-User =
Nobody-Group =[Translation]
Method = nsswitch[/code]Create folder /autofsmounts/kancelarija
[code]mkdir /autofsmounts/kancelarija[/code]
then restart autofs (as root):
[code]service autofs restart[/code]Create folder /kancelarija
[code]mkdir /kancelarija[/code]and inside place symlinks for:
/autofsmounts/kancelarija/etc
/autofsmounts/kancelarija/extra
/autofsmounts/kancelarija/home
/autofsmounts/kancelarija/ostalo
/autofsmounts/kancelarija/usr
/autofsmounts/kancelarija/varby first entering those folders so they would show inside “/autofsmounts/kancelarija/” folder. If not use, they will timeout in 10 seconds (in my example)
[code]cd /autofsmounts/kancelarija/
cd etc; ln -s /autofsmounts/kancelarija/etc /kancelarija/; cd ..
cd extra; ln -s /autofsmounts/kancelarija/extra /kancelarija/; cd ..
cd home; ln -s /autofsmounts/kancelarija/home /kancelarija/; cd ..
cd ostalo; ln -s /autofsmounts/kancelarija/ostalo /kancelarija/; cd ..
cd usr; ln -s /autofsmounts/kancelarija/usr /kancelarija/; cd ..
cd var; ln -s /autofsmounts/kancelarija/var /kancelarija/; cd ..[/code]I hope I have not made any mistakes. If I have, please point them out to me so i can fixed them.
