Pendahuluan
Network File System (NFS) merupakan salah satu layanan jaringan yang banyak digunakan. NFS memungkinkan client untuk menempelkan harddisk yang ada di jaringan.
Skenario
Dalam skenario ini kita akan menempelkan harddisk yang ada di linuxconfig.org (IP address 10.1.1.200) ke client IP address 10.1.1.100).
Persyaratan
Install NFS
apt-get install nfs-common nfs-kernel-server
Pastikan mesin kita mendukung NFS ketik
$ cat /proc/filesystems
keluar
nodev nfs nodev nfs4 nodev nfsd
NFS daemon harusnya mendengerkan port 2049 dan portmap pada port 111.
more /etc/services | grep 111
keluar
sunrpc 111/tcp portmapper # RPC 4.0 portmapper sunrpc 111/udp portmapper
more /etc/services | grep 2049
keluar
nfs 2049/tcp # Network File System nfs 2049/udp # Network File System
Cara lain untuk cek menggunakan
rpcinfo -p
keluar
program vers proto port 100000 2 tcp 111 portmapper 100000 2 udp 111 portmapper 100024 1 udp 56835 status 100024 1 tcp 53408 status 100021 1 udp 50903 nlockmgr 100021 3 udp 50903 nlockmgr 100021 4 udp 50903 nlockmgr 100021 1 tcp 36404 nlockmgr 100021 3 tcp 36404 nlockmgr 100021 4 tcp 36404 nlockmgr 100003 2 udp 2049 nfs 100003 3 udp 2049 nfs 100003 4 udp 2049 nfs 100003 2 tcp 2049 nfs 100003 3 tcp 2049 nfs 100003 4 tcp 2049 nfs
4. Server export file
All NFS server exports need to be defined in /etc/exports file. 4.1. Most common exports options
Here are the most common export techniques and options: /home/nfs/ 10.1.1.100(rw,sync) export /home/nfs directory for host with IP 10.1.1.100 with read, write permissions, and synchronized mode /home/nfs/ 10.1.1.0/24(ro,sync) export /home/nfs directory for network 10.1.1.0 netmask 255.255.255.0 with read only permissions and synchronized mode /home/nfs/ 10.1.1.100(rw,sync) 10.1.1.10(ro,sync) export /home/nfs directory for host with IP 10.1.1.100 with read, write permissions, synchronized mode, and also export /home/nfs directory for hosts with IP 10.1.1.10 with read only permissions and synchronized mode /home/nfs/ 10.1.1.100(rw,sync,no_root_squash) export /home/nfs directory for host with IP 10.1.1.100 with read, write permissions, synchronized mode and the remote root user will be treated as a root and will be able to change any file and directory. /home/nfs/ *(ro,sync) export /home/nfs directory for any host with a read only permission and synchronized mode /home/nfs/ *.linuxconfig.org(ro,sync) export /home/nfs directory for any host within linuxconfig.org domain with a read only permission and synchronized mode /home/nfs/ foobar(rw,sync) export /home/nfs directory for hostname foobar with read, write permissions and synchronized mode 4.2. Edit exports file
Open up your favorite text editor, for example, vim and edit /etc/exports file and add line /home/nfs/ *(ro,sync) to export /home/nfs directory for any host with read only permissions. edit NFS exports file
Be sure that the directory you export by NFS exists. You can also create a file inside the /home/nfs directory which will help you troubleshoot once you mount this file system remotely.
# touch /home/nfs/test_file
4.3. Restart NFS daemon
Once you edit /etc/exports file you need to restart NFS daemon to apply changes in the /etc/exports file. Depending on your Linux distribution, the restarting of NFS may differ. Debian users:
# /etc/init.d/nfs-kernel-server restart
Redhat users
# /etc/init.d/nfs restart
If you later decide to add more NFS exports to the /etc/exports file, you will need to either restart NFS daemon or run command exportfs:
# exportfs -ra
