Example:

Nfs server: 172.16.100.1

Client: 172.16.100.3

1. Create a mount point and mount it on the client:

S#vim / etc/exports

/ data 172.16.100.3 Compact 16 (rw)

/ read 172.16.100.3 Compact 16 (ro)

C#mount-t nfs 172.16.100.1:/data / sqld/mdata

C#showmount-a 172.16.100.1

C#showmount-e 172.16.100.1

C#showmount-d 172.16.100.1

two。 Re-export without restarting the service

S#S#vim / etc/exports

/ data 172.16.100.3 Compact 16 (rw)

# / read 172.16.100.3 Universe 16 (ro)

S#exprotnfs-rav re-export

C#showmount-e 172.16.100.1

3. Qualify export attributes

The authentication of nfs is based on the uid and gid of the account.

S#id hadoop

Uid=502 gid=502

S#setfacl-m u:hadoop:rwx / read

S#su-hadoop

S$cd / data

S$touch a.hadoop

C#groupadd-g 502 openstack

C#useradd-u 502-g 502 openstack

S#exportfs-ra

C#mount-t nfs 172.16.100.1:/data / sqld/mdata

C#ll / sqld/mdata

A.hadoop openstack openstack

C#su-openstackl

C$cd / sqld/mdata

C$touch b.openstack

S#ll / read

At this point, you will find that the main group of b.openstack is hadoop.

S#useradd-u 510 nfstest

S#cd / data

S#touch c.nfstest

S#chown nfstest:nfstest c.nfstest

S#vim / etc/exprots

/ data 172.16.100.3 Compact 16 (rw,all_squash,anonuid=510,nanogid=510) qualified export attributes

# / read 172.16.100.3 Universe 16 (ro)

S#exportfs-rav

C#umount / sqld/mdata

C#mount-t nfs 172.16.100.1:/data / sqld/mdata

C#ll / sqld/mdata

4. Client boot mount:

C#vim / etc/fstab

172.16.100.1:/data / sqld/mdata nfs defaults,_netdev 00

5. The server process uses a fixed port:

S#vim / etc/sysconfig/nfs

MOUNTD_PORT=892

RQUOTAD_PROT=875

LOCKD_TCPPORT=32083

LOCKD_UDPPORT=32769
