Kurze Anleitung zur Installation von NFS Version 4 unter CentOS 7.
System
CentOS 7.1 in der Minimalinstallation
System aktualisieren
# yum check-updates
# yum update
NFS Server installieren
# yum -y install rpcbind nfs-utils nfs4-acl-tools libnfsidmap
rpcbind – setzt Ports dynamisch für RPC Dienste
NFS Verzeichnis erstellen
# mkdir -p /share
NFS ISO Export read write erlauben
# mcedit /etc/exports
/share *(rw) #all clients or ->
/share 192.168.0.0(rw) #only from 0.x net
NFS Berechtigung vergeben
# chmod -R 777 /export
NFS konfigurieren
NFSV4.1 Ports für moutd, statd und lockd werden nicht benötigt. Da sich die Ports nicht dynamisch ändern sollen, werden sie nun fest konfiguriert.
# mcedit /etc/sysconfig/nfs
LOCKD_TCPPORT=32803
LOCKD_UDPPORT=32769
RPCNFSDCOUNT=16
RPCMOUNTDOPTS=”-p 892″ #use always port 982
RPCRQUOTADOPTS=”-p 875″ #muss nicht
STATDARG=”-p 662 -o 2020″
GSS_USE_PROXY=”no”
NFS Firewall konfigurieren
NFS Service zur Firewall hinzufügen
# firewall-cmd –permanent –add-service=nfs
oder
# firewall-cmd –permanent –zone=public –add-service=nfs
# firewall-cmd –permanent –zone=public –add-service=mountd
# firewall-cmd –permanent –zone=public –add-service=rpc-bind
success
Firewall neu laden
# firewall-cmd –reload
success
NFS Dienste zur Bootzeit
# systemctl enable rpcbind
# systemctl enable nfs-server
# systemctl enable nfs-lock #no such file or directory bei mir
# systemctl enable nfs-idmapd
The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit’s
.wants/ or .requires/ directory.
2) A unit’s purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, …)

NFS Shares lokal prüfen
# showmount -e localhost / # showmount -e hostname
Export list for nfsserver.localdomain:
/shares 192.168.0.0/24
NFS Shares remote prüfen
# showmount -e nfsserver
Export list for nfsserver.localdomain:
/shares 192.168.0.0/24
NFS Client Share mounten
# mount -t nfs nfsserver:/export /mnt/nfs
