Remote Filesystem

Learn how to use nfs autofs and samba.

NFS :

NFS, which is an acronym for (Network File system) is a distributed file system protocol. NFS is server-client based, where the NFS server will be configured and clients can access files on the server over a network just as if they were on the server.

Step by step am going to show you how to use the nfs share. Assuming we want to share the directory /database from server 1 to server2 SERVER 1 : IP ; 192.168.222.131

1. systemctl enable --now nfs-server.service

2. systemctl status nfs-server.service

3. vim /etc/export >>/database 192.168.222.129(rw,sync,no_root_squash) save and quit

4. firewall-cmd --add-service={rpc-bind,nfs,mountd} --permanent

5. firewall-cmd --reload

6. exportfs -arv

Moving to SERVER 2 : IP; 192.168.222.129

1. systemctl enable --now nfs-server.service

2. systemctl status nfs-server.service

3. firewall-cmd --add-service={rpc-bind,nfs,mountd} --permanent

4. firewall-cmd --reload

5. showmount -e 192.168.222.131

6. mkdir /database-mp

7. echo "192.168.222.131:/database /database-mp nfs _netdev 0 0" >> /etc/fstab.

8. mount -a

Autofs :

Lazy load volumes when they are needed, not simply at boot-time with fstab.

• Install the autofs package

• /etc/auto.master defines the directory and mount options file ex: /data /etc/auto.data

• /etc/auto.data defines the sub-directory (within /data) and how to mount the thing ex: files -rw nfs.evilcorp.com:/data/files

• Start autofs service

• Automount when started will auto create /misc and /net, which it uses

• There are great examples in /etc/auto.misc

• Automount will auto unmount idle volumes
