NFS就像是windows的網方一樣,
NFS client可以藉由掛載的方式使用NFS Server上的空間.
以下指令請使用root權限 或 sudo來執行
Server安裝
yum install -y nfs-utils nfs-utils-lib
建立一個分享的目錄+開啟權限
mkdir /var/sharedNFS
chmod -R 777 /var/sharedNFS
編輯設定檔->哪個目錄要分享與相關權限
vi /etc/exports
/var/sharedNFS 192.168.30.31(rw,sync,no_root_squash,no_subtree_check)
/var/sharedNFS 192.168.30.32(rw,sync,no_root_squash,no_subtree_check)
每次修改exports都要執行下面的指令
exportfs -a
關閉防火牆 (我懶了,直接關掉)
service iptables stop
chkconfig iptables off
如果要加入規則,請參考
https://mcdee.com.au/tutorial-configure-iptables-for-nfs-server-on-centos-6/ or
設定服務啟動
chkconfig nfs on
service rpcbind start
service nfs start
Client安裝
yum install -y nfs-utils nfs-utils-lib
永久建立掛載的目標目錄
mkdir -p /mnt/nfs/sharedNFS
掛載
mount 192.168.30.11:/var/sharedNFS /mnt/nfs/sharedNFS
檢查磁碟,便可知是否有掛載成功
df -h
192.168.30.11:/var/sharedNFS 3.9G 659M 3.0G 18% /mnt/nfs/sharedNFS
mount
/dev/mapper/vg_template-lv_root on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
/dev/sda1 on /boot type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
192.168.30.11:/var/sharedNFS on /mnt/nfs/sharedNFS type nfs (rw,vers=4,addr=192.168.30.11,clientaddr=192.168.30.32)
確保重開機後還是掛載狀態,在fstab加入一行(如果是server重啟,還是得手動掛載,所以推薦另一個作法,參考使用動態載入 autofs )
vi /etc/fstab
192.168.30.11:/var/sharedNFS /mnt/nfs/sharedNFS nfs auto,noatime,nolock,bg,nfsvers=3,intr,tcp,actimeo=1800 0 0
測試的話就在client寫個檔看看就知道囉
