NFS Deployment and optimization

1. Installation of nfs-utils and Rpcbind programs

Yum install-y nfs-utils Rpcbind

2. Edit Exports

Vim/etc/exports

/mnt 10.10.13.248 (Rw,sync)

3. Install Nfs-utils on the client and view shared information

[email protected] ~]# Yum install-y nfs-utils

[Email protected] ~]# showmount-e 10.10.13.247

return results

Export list for 10.10.13.247:

/mnt 10.10.13.248

4. Mount on Client

[Email protected] ~]# mount-t NFS 10.10.13.247:/mnt/opt

5. Change permissions for shared directories on the server side

[Email protected] ~]# chmod 777/mnt

6. Create a file on the client

Cd/opt

Vim 1.txt

Successfully created

7. Restrict users ' permissions to shared folders

Edit the configuration file on the server side

Vim/etc/exports

Revision changed to

/mnt 10.10.13.248 (rw,sync,all_squash,anonuid=502,anongid=502)

Reload the configuration file on the server after modification

Exportfs-arv or restart service-side NFS Service

Reload after the client unloads the disk to view shared file permissions

[Email protected] opt]# Umount 10.10.13.247:/mnt

Mount-t nfs-onolock,nfsvers=3 10.10.13.247:/mnt/opt

[Email protected] opt]# cd/opt

[Email protected] opt]# ls-l

You can see that the created file belongs to the main group and becomes river

-rw-r--r--. 1 River 6 May 11:10 3.txt

8, do not limit the root sharing permissions

Service-side edit config file changed to

/mnt 10.10.13.248 (Rw,sync,no_root_squash)

Reload the configuration file Exportfs-arv

After the client unloads the disk and reloads the file, it can be found that the file belongs to the master group and becomes root.

-rw-r--r--. 1 root root 7 May 11:23 4.tx
