NFS服務部署

NFS：Network File System，網絡文件系統，主要用來實現網絡文件共享。 

---------------------server

1、創建共享目錄
[root@server /]# mkdir /home/TestNFS

2、創建文件
[root@server /]# cd /home/TestNFS/
[root@server TestNFS]# touch test.txt

3、修改exports，配置nsf提供的文件共享目錄
[root@server home]# vim /etc/exports

[root@server home]# cat /etc/exports
/home/TestNFS/ 192.168.0.104(rw,async,no_root_squash)

[root@server home]# exportfs -rv
exporting 192.168.0.104:/home/TestNFS


---------------------client

1、查看NFS服務器是否允許本機鏈接對應的共享目錄
[root@client1 /]# showmount -e 192.168.0.104
Export list for 192.168.0.104:
/home/TestNFS 192.168.0.104

2、創建本地掛載點
[root@client1 /]# cd /home/dana
[root@client1 home]# mkdir nfs
[root@client1 home]# ls
dana  nfs

3、掛載共享目錄
[root@client1 home]# mount 192.168.0.104:/home/TestNFS nfs
mount.nfs: access denied by server while mounting 192.168.0.104:/home/TestNFS

報錯：mount.nfs: access denied by server while mounting 192.168.0.104:/home/TestNFS

原因：NFS服務啟動，所使用的端口要求小于1024，而當前虛擬機采用NAT的方式，其網絡地址端口轉換的時候，一般都是大于1024的，需要禁止secure選項，即添加insecure。

[root@server /]# cat /var/log/messages | grep mount
……
Jan 14 22:59:46 localhost rpc.mountd[13367]: refused mount request from 192.168.0.104 for /home/TestNFS (/home/TestNFS): illegal port 37636

處理方法：server端修改exports
[root@server /]# vim /etc/exports
[root@server /]# cat /etc/exports
/home/TestNFS/ 192.168.0.104(insecure,rw,async,no_root_squash)
[root@server /]# exportfs -rv
exporting 192.168.0.104:/home/TestNFS

4、重新掛載共享目錄

[root@client1 home]# mount 192.168.0.104:/home/TestNFS nfs

root@client ~]# mount
……
nfsd on /proc/fs/nfsd type nfsd (rw)
192.168.0.104:/home/TestNFS on /home/nfs type nfs (rw,vers=4,addr=192.168.0.104,clientaddr=172.16.71.129)

5、查看文件
[root@client1 home]# cd nfs
[root@client1 nfs]# ls
test.txt
