```
rpm -q libselinux-python
```
- Install dependencies device-mapper-libs, conntrack, sshpass, Check the download link for dependencies. Installation command is as follows:
```
rpm -ivh <package name>
```
- Manually modify the VERSION_ID="7" in the os-release file.
```
vi /etc/os-release
```
Refer to Creating OS Package Offline Package to start creating the offline package.
Download the addon offline package, you can download the latest version from the download center (optional).

Set up the cluster configuration file clusterConfig.yaml, you can obtain this file under the offline package offline/sample and modify it as needed. The reference configuration is:

apiVersion: provision.daocloud.io/v1alpha3
kind: ClusterConfig
metadata:
  creationTimestamp: null
spec:
  clusterName: my-cluster
  masterNodes:
    - nodeName: "master1"
      ip: 10.6.135.199
      ansibleUser: "root"
      ansiblePass: "dangerous@2024"
  workerNodes: []
  osRepos:
    type: none # (1)!
  imagesAndCharts:
    type: builtin
  binaries:
    type: builtin
  loadBalancer:
    type: NodePort
  fullPackagePath: /home/offline

Change to none.

Start installing DCE 5.0.
```
./dce5-installer cluster-create -m ./sample/manifest.yaml -c ./sample/clusterConfig.yaml
```
Note

You can check more parameters by using ./dce5-installer --help:
- -z Minimal installation
- -c Specify the cluster configuration file, not required when exposing the console using NodePort
- -d Enable debug mode
- --serial Specify all installation tasks to be executed serially
