How to set up network storage (such as NFS) on Linux
Introduction:
NFS (Network File System) is a protocol that allows files to be shared on the network. It allows multiple Linux servers to share files over the network, providing efficient file access and data sharing. This article will introduce how to set up NFS on Linux to build network storage.
Step 1: Install NFS server software
First you need to install NFS server software on the server. On most Linux distributions, it can be installed through a package manager. Taking Ubuntu as an example, you can install it with the following command:
sudo apt-get install nfs-kernel-server
Step 2: Create a shared directory
Next, we need to select a directory as the shared directory. You can select an existing directory or create a new one. Taking the new directory as an example, you can use the following command to create a directory named nfs_share:
sudo mkdir /nfs_share
Step 3: Configure the NFS server
Before configuring the NFS server, we need to edit/ etc/exports
file to specify the shared directory and access permissions. Open the terminal and enter the following command to edit the /etc/exports
file:
sudo nano /etc/exports
In the open file, add the following content:
/nfs_share *(rw,sync,no_root_squash,no_subtree_check)
hererw
means allowing read and write permissions, sync
means synchronous writing, no_root_squash
means allowing root user access, no_subtree_check
means turning off subdirectory checking. If you need to restrict access, you can adjust this as needed.
Save and close the file.
Step 4: Reload the configuration
After the configuration is completed, you need to reload the NFS server configuration. Enter the following command in the terminal:
sudo exportfs -r
Step 5: Start the NFS server
Enter the following command to start the NFS server:
sudo systemctl start nfs-server
Step 6: Configure the NFS client
NFS client software also needs to be installed on the client. Taking Ubuntu as an example, you can install it through the following command:
sudo apt-get install nfs-common
Step 7: Mount the NFS shared directory
On the client, use the following command to mount the NFS shared directory:
sudo mount server_ip:/nfs_share /mnt
Here server_ip
is the IP address of the NFS server, /nfs_share
is the path to the shared directory, and /mnt
is the path to the mount point. Other suitable mount points can be selected as needed.
Step 8: Test the NFS share
On the client, use the following command to test whether the NFS share is normal:
cd /mnt touch testfile
If no error message appears, it means the NFS share The configuration has been successful.
Note:
/etc/fstab
file. Summary:
NFS is a very convenient and efficient network storage solution that can share files between Linux servers. This article describes the steps to set up NFS on Linux and provides corresponding code examples. Hope this article helps you!
