NFS file sharing for Linux

First, configure NFS sharing

Network File system

--Purpose: To provide the client with shared folders

--Protocol: NFS (TCP/UDP 2049) RPC (TCP/UDP 111)

Required Packages: Nfs-utils

System Services: Nfs-server

Building basic read-only NFS services

1. On the virtual machine Server0, detect if the nfs-utils is installed

[Email protected]/]# rpm-q nfs-utils

2. Modify the configuration file/etc/exports

[Email protected]/]# Mkdir/public

[Email protected]/]# echo Hehelele >/public/nsd.txt

[Email protected]/]# Vim/etc/exports

/public 172.25.0.0/24 (RO)

3. Restart Nfs-server service, set boot from

[Email protected]/]# systemctl restart Nfs-server

[Email protected]/]# Systemctl enable Nfs-server

4. Client access to the Nfs-server service

[Email protected]/]# Mkdir/mnt/nfs

[Email protected]/]# showmount-e 172.25.0.11

[Email protected]/]# Vim/etc/fstab

172.25.0.11:/public/mnt/nfs NFS _netdev 0 0

[Email protected]/]# mount-a

[Email protected]/]# Ls/mnt/nfs

If you need to read and write, you need to modify the configuration file on the server

Service side:

[Email protected]/]# Vim/etc/exports

/ABC 172.25.0.0/24 (Rw,no_root_squash) #不压榨客户端root权限

[Email protected]/]# systemctl restart Nfs-server

Normal User:

Client access to the service-side Nfs-server service,

The server will determine the permissions of the local user with the same UID as the client.
