This article will explain in detail how to build NFS under Linux. The quality of the article is high, so Xiaobian shares it with you as a reference. I hope you have a certain understanding of relevant knowledge after reading this article.

NFS stands for Network File System. NFS is a network protocol for file sharing between systems that allows users to access files shared on the network as if they were local files.

CentOS comes with NFS functionality

yum install -y nfs-utils rpcbind

This experimental platform: CentOS release 6.8 (Final) Server IP: 172.17.99.67 Customer IP: 172.17.99.61 I. Environment construction 1. Edit the configuration file/etc/exportsvim /etc/exports

/ane/data/LBLOGS 172.17.99.61(rw,sync,no_root_squash)

/ane/data/LPLOGS *(ro,sync)

#indicates that only 172.17.99.61 has read and write permissions LBLOGS, only read permissions LPLOGS

2. modify fixed port vim /etc/sysconfig/nfs

RQUOTAD_PORT=30001

LOCKD_TCPPORT=30002

LOCKD_UDPPORT=30002

MOUNTD_PORT=30003

STATD_PORT=30004

Second, build NFS1. Create nfs shared directory mkdir /ane/data/LBLOGS -p

mkdir /ane/data/LPLOGS -p

2. Start nfs service nfs start

service rpcbind start

3. showmount -e 172.17.99.131

clnt_create: RPC: Program not registered

#This error is caused by the wrong order of starting nfs application

4. restart nfs service nfs stop

service rpcbind stop

#must be started in the following order

service rpcbind start

service nfs start

5. Customer service inquiry showmount -e 172.17.99.67

Export list for 172.17.99.67:

/ane/data/LBLOGS 172.17.99.61(rw,sync,no_root_squash)

/ane/data/LPLOGS *(ro,sync)

6. mount -t www.example.com/ane/data/LBLOGS 172.17.99.67:/ane/data/LBLOGS

mount -t 172.17.99.67:/ane/data/LPLOGS /ane/data/LPLOGS

7. Check mount| grep nfs

172.17.99.67:/ane/data/LBLOGS on /ane/data/LBLOGS type nfs (ro,vers=4,addr=172.17.99.67,clientaddr=172.17.99.61)

172.17.99.67:/ane/data/LPLOGS/ on /ane/data/LPLOGS type nfs (rw,vers=4,addr=172.17.99.67,clientaddr=172.17.99.61)

III. Other nfs configurations 1. The requested URL/data/index.php was not found 172.17.99.131:/ane/data/YTLOGS/

mount.nfs: access denied by server while mounting 172.17.99.131:/ane/data/YTLOGS/

#Because of version issues

mount -o v3 172.17.99.131:/ane/data/YTLOGS/ /ane/data/YTLOGS/ #Specify the version to mount

2. On-demand automount (indirect mapping)#modify timeout for inactivity

vim /etc/sysconfig/autofs

TIMEOUT=300

Amend to

TIMEOUT=600

That is, the inactivity timeout was changed from 5 minutes to 10 minutes.

3. Install vim /etc/fstab

172.17.99.67:/ane/data/LPLOGS /ane/data/LPLOGS nfs defaults 0 0

4. Linux is a free-to-use and freely distributed UNIX-like operating system, is a POSIX-based multi-user, multi-task, multi-threaded and multi-CPU operating system, using Linux to run major Unix tools, applications and network protocols.
