[Galaxy Kirin V10] [desktop] build NFS to realize disk sharing

Environmental Science ： Galaxy Unicorn V10 0710 desktop

Experimental scenario ： take A Mechanical sdb1 The disk is shared to the machine B,AB All kylin V10 0710 Desktop system

A machine IP：192.168.1.64

B machine IP：192.168.1.72

The first 1 Step ：

Mount the disk directory to the folder , If it is mounted, it can be ignored

# mkdir /home/arvin/ desktop / share      //arvin Is the actual user name , This path can be customized

# mount  /dev/sdb1  /home/arvin/ desktop / share

# chmod  -R  777  /home/arvin/ desktop / share

# lsblk

 # blkid  /dev/sdb1    // obtain UUID

# vim /etc/fstab   // write in fstab, It can start automatically , Add a line as shown in the figure below ,UUID Modify... According to the actual situation  

# mount  -a   // verification fstab File format , No error can be reported

The first 2 Step ： install

install nfs Related components , And open nfs service

# apt search nfs-kernel-server -y

# apt install rpcbind -y

# systemctl enable nfs-server.service

# systemctl enable rpcbind

The first 3 Step ： Configure sharing

# vim  /etc/exports

Add the following ：

/home/arvin/ desktop / share         192.168.1.0/24(rw,sync,no_subtree_check,crossmnt)

Pictured above ：/home/arvin/ desktop / share   Indicates the shared directory path ,192.168.1.0/24 Means that only 192.168.1.0 The machines in this network segment discover and share this directory , among 24 It's the subnet mask , If any host is allowed to access 192.168.1.0/24 Replace with *

# systemctl restart rpcbind

# systemctl restart nfs-server.service

# showmount -e localhost      // Verify whether the server configuration is successful

The first 4 Step ： Open the server （A machine ） Security center firewall

（ If you can turn off the firewall directly, you can skip this step , If there is no firewall closing function, please refer to this step ）

 # apt  install  ksc-defender  -y    // Press enter directly in the prompt pop-up box , Reopening the security center after installation has the function of closing the firewall

The first 5 Step ： Client side Settings

# showmount -e 192.168.1.64     // The following shows that the server can be found successfully nfs service

  Client create directory , And mount

# sudo mkdir /home/arvin/ desktop / share         // You can create a shared directory under the local desktop directory ,arvin Normal user name , Modify according to the time ,“ share ” For folder name , Customizable

# sudo chmod -R 777 /home/arvin/ desktop / share /

# sudo mount -t nfs 192.168.1.64:/data2 /home/arvin/ desktop / share /    

The first 6 Step ： Set up auto mount after power on

（ It is not recommended to write /etc/fstab, Prevent the client from failure of post due to abnormal server , It is suggested that /etc/rc.local）

# chmod 755 /etc/rc.local

# vim /etc/rc.local    // Add the following

sudo mount -t nfs 192.168.1.64:/home/arvin/ desktop / share    /home/arvin/ desktop / share

The first 7 Step ： Verify that the restart takes effect

# reboot     // Restart first A machine

# lsblk   // see sdb1 Whether the disk is powered on and mounted

# showmount -e localhost   // see nfs Startup and self startup

# reboot   // restart B machine

# showmount  -e  192.168.1.64

# df  -Th    // Check whether the mount realizes automatic startup

 

  Finally, on the desktops of both systems “ share ” Folder directory create file , See if you can see both sides at the same time
