Prerequisites

The server on which you install the EasyYitian migration tool must meet the following conditions:

It must be a Linux server with an x86 architecture.
Docker must be installed. For more information, see Install and use Docker and Docker Compose.

Install EasyYitian

Log on to the Linux server where you want to install the EasyYitian migration tool.
Download the Docker image for EasyYitian.

Important
If the server cannot access the Internet, download the image on another server and then upload it to this server.
```
wget https://help-static-aliyun-doc.aliyuncs.com/file-manage-files/zh-CN/20231024/ohqx/easyyitian_1.0.0.tar
```
Load the Docker image for EasyYitian.
```
sudo docker load -i easyyitian_1.0.0.tar
```
When a message similar to the following one is returned, the Docker image is loaded successfully.
View the Docker image ID.
```
sudo docker images
```
The value in the IMAGE ID column is the image ID.
Start the easyyitian service.
```
sudo docker run -itd -p <port>:8000 -v </path/to/local/volume>:/app/workspace --name easyyitian <imageId>
```
Important
- Replace <port> with an actual port number, such as 8000. You must open this port in the security group.
- Replace </path/to/local/volume> with the path of the local volume that you want to mount, such as /home/user.
- Replace <imageId> with the image ID that you obtained in step 4.
When a message similar to the following one is returned, the easyyitian service is started successfully.
