This article mainly introduces how to set up the NFS server and mount the mount command in linux. It is very detailed and has a certain reference value. Interested friends must read it!

For example, there are three machines now.

A:10.100.100.1

B:10.100.100.2

C:10.100.100.3

B and C should mount A's / app/data folder to their own / app/buckup folder.

1. NFS server settings (mount source)

Edit the / etc/exports file on machine A, which is used to configure allowable mount configuration files

Rw: read and write permissions

Ro: read-only permission

No_root_squash: if the user who logs in to the NFS host is root, the user has root permission

Root_squash: if the user who logs in to the NFS host is root, the user right will be limited to anonymous user nobody

All_squash: regardless of the permissions of the user who logs in to the NFS host, it will be reset to anonymous user nobody.

Anonuid: all users who log in to the NFS host are set to the specified user id. This ID must exist in / etc/passwd.

Anongid: same as anonuid, but just become group ID!

Sync: data is synchronously written to memory.

Async: the data will be temporarily stored in memory and will not be directly written to the hard disk.

Insecure: unauthorized access from this machine is allowed.

Then you need to write in the / etc/exports file of A:

Exportfs

Command

If we modify / etc/exports after starting NFS, we can use the exportfs command to make the changes take effect immediately, which is in the following format:

Exportfs [- aruv]

-a: all mount or unmount / etc/exports content

-r: revisit the directory shared in mount / etc/exports

-u: umount directory

-v: in export, output the detailed information to the screen.

Second, the operation of NFS client:

1. Install nfs and rpcbind services like the server

two。 Mount using the monut command

Mount 10.100.100.1:/app/data / app/backup
