1the usage scenario of NFS service

The working principle of 2Det NFS service

1) the client passes the command to the NFS server for execution

2) client-to-server delivery is based on the underlying TCP/IP protocol and RPC process

3) rpc.nfst determines whether the client has nfs link permission, and rpc.mount determines whether the nfs client has authentication permission.

Portmap is a random port table formed by running rpc services

Note: you must first run RPC to run NFS

3. Install the NFS service server

Yum search nfs to view software packages for nfs services

Yum-y install nfs-utils

Rpcinfo-p View portmap

Rpcbind port: 111,

Nfs ports: randomly generated

4, profile

/ etc/exports

Rw: read and write permissions

Ro: read-only permission

Sync: see data written to memory and hard disk at the same time to ensure data security

All_squash: no matter what user the client accesses, the server is implied as an anonymous user

Anonuid,anongid: indicates that you can specify users (ordinary users) to access

5. Start the server

Systemctl start rpcbind nfs

Systemctl status rpcbind nfs

Showmount-e test

6. Nfs is installed on the client

Yum-y install nfs-utils

7, start

Systemctl start rpcbind

Showmount-e 172.16.1.31

8, mount

Mount-t nfs 172.16.1.31:/data / data (Mount the shared directory data of 172.16.1.31 to the client / data in nfs format

At this point, any data written on the client / data is shared under the server / data.

9, exercises:

Power on and mount automatically
