Edite / etc / exports no lado do servidor e escreva o seguinte diretório compartilhado (recursos)

[root@abc123 ~]# cat  /etc/exports
/home/lee/nfs 2.1.1.*(rw,async,no_root_squash)
/data  2.1.1.*(rw)

Efetivo imediatamente

[root@abc123 ~]# exportfs -arv
exporting 2.1.1.*:/data
exporting 2.1.1.*:/home/lee/nfs

1. Instalação

 yum install nfs-utils

Veja o diretório de recursos disponíveis

[root@nfs16 ~]# showmount -e 2.1.1.123
Export list for 2.1.1.123:
/data         2.1.1.*
/home/lee/nfs 2.1.1.*

Monte usando o seguinte comando

mount -t nfs 2.1.1.123:/data /xuexi

Verifique se a montagem foi bem-sucedida

[root@nfs16 ~]# df -h

Verifique se você pode adicionar, excluir, verificar e modificar

[root@nfs16 ~]# echo 1223 >> /xuexi/123.txt
[root@nfs16 ~]# cat /xuexi/123.txt 
1223
1223
[root@nfs16 ~]# rm -rf /xuexi/123.txt 
[root@nfs16 ~]# ll /xuexi/123.txt
ls: 无法访问'/xuexi/123.txt': No such file or directory

Montagem permanente + montagem automática
vim / etc / fstab na inicialização

[root@nfs16 ~]# tail -n 1 /etc/fstab 
2.1.1.123:/data      /xuegoddate     nfs    defaults       0 0

Da seguinte forma:

insira mount -a

[root@nfs16 ~]# mount -a
[root@nfs16 ~]# df -h
