NFS Limited Export attribute instance, etc.

Instance:

Server for NFS: 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 172.16.100.3/16 (rw)

/read 172.16.100.3/16 (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

2. Do not restart the service re-export

S#s#vim/etc/exports

/data 172.16.100.3/16 (rw)

#/read 172.16.100.3/16 (RO)

S#exprotnfs-rav re-export

C#SHOWMOUNT-E 172.16.100.1

3. Qualifying Export Properties

Authorization for 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, we find that the genus B.openstack belong to Hadoop.

S#useradd-u 510 Nfstest

S#cd/data

S#touch C.nfstest

S#chown nfstest:nfstest C.nfstest

S#vim/etc/exprots

/data 172.16.100.3/16 (rw,all_squash,anonuid=510,nanogid=510) qualifying export Properties

#/read 172.16.100.3/16 (RO)

S#exportfs-rav

C#umount/sqld/mdata

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

C#ll/sqld/mdata

4. Mount the client:

C#vim/etc/fstab

172.16.100.1:/data/sqld/mdata NFS Defaults,_rnetdev 0 0

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
