Location in the network disk（Ubuntu 18.04）：iManager部署包/软件工具包/NFS Server离线安装包/nfs-server-offline-ubuntu-18.04.zip

NFS Server Installation Steps

Here we take CentOS system as an example. The installation method of Ubuntu system is similar. If you already have an NFS server, you can skip this step.

Unzip nfs-server-offline-centos-7.5.zip on your local computer to get the supermap-nfs-server folder;
Copy the supermap-nfs-server folder to any machine, and then follow the following commands:

Enter the supermap-nfs-server folder:
```
cd supermap-nfs-server
```
Execute the installation script:
```
sudo chmod +x install.sh && ./install.sh
```
The installation is complete as shown in the figure below.

Storage location of nfs after installation: /opt/nfs_data

You can verify whether the nfs installation is successful by:
```
mkdir test
mount -t nfs <ip>:/opt/nfs_data test

Parameter Description:
<ip> is the IP address of the machine where the NFS Server is located
```
After executing the above command, you can enter the “test” directory and create a file. For example, use the following command: vim test.txt. You can enter any character to save and exit: press the keyboard Esc key, enter “:wq” in the command line and press Enter. Then enter the /opt/nfs_data directory and use the following command: ll or ls -l. If the following figure is displayed, it means that the NFS Server is successfully installed.

Non-root users can verify whether the nfs installation is successful by the following method:
```
service nfs status
```
The result is as follows: The installation is successful:

If NFS Server, Ceph and other storage environments cannot be used, you can also install Longhorn。
