Deploy DCE 5.0 Enterprise on UOS V20 (1020a)¶

This page introduces how to deploy DCE 5.0 on UOS V20(1020a). Installer v0.6.0 and higher versions support this deployment method.

Prerequisites¶

• Read Deployment Architecture in advance to confirm this deployment mode.
• Read Deployment Requirements in advance to confirm whether the network, hardware, and ports meet the requirements.
• Read Preparation in advance to confirm machine resources and pre-check.

Offline installation¶

1. Since the installer depends on python, you need to install python3.6 on the tinder machine first.

   # download dependencies
   dnf install -y --downloadonly --downloaddir=rpm/python36
   
   # start the installation
   rpm -ivh python3-pip-9.0.3-18.uelc20.01.noarch.rpm python3-setuptools-39.2.0-7.uelc20.2.noarch.rpm python36-3.6.8-2.module+uelc20+36 +6174170c.x86_64.rpm
   

2. Download the full mode offline package, you can download the latest version in Download Center.

   CPU Architecture	Version	Download URL
   AMD64	v0.17.0	https://qiniu-download-public.daocloud.io/DaoCloud_Enterprise/dce5/offline-v0.17.0-amd64.tar

   Unzip the offline package after downloading:

   curl -LO https://qiniu-download-public.daocloud.io/DaoCloud_Enterprise/dce5/offline-v0.17.0-amd64.tar
   tar -xvf offline-v0.17.0-amd64.tar
   

3. Download the UnionTech Server V20 1020a ISO image.

   curl -LO https://cdimage-download.chinauos.com/uniontechos-server-20-1020a-amd64.iso
   

4. Make the os-pkgs-uos-20.tar.gz file.

   Download the production script

   curl -Lo ./build.sh https://raw.githubusercontent.com/kubean-io/kubean/main/build/os-packages/others/uos_v20/build.sh
   chmod +x build.sh
   

   Run the script to generate os-pkgs-uos-20.tar.gz file:

   ./build.sh
   

5. Download the addon offline package, you can download the latest version in Download Center (optional)

6. Edit clusterConfig.yaml, which can be obtained under the offline package offline/sample and modified as needed. The sample configuration is for your reference:

   apiVersion: provision.daocloud.io/v1alpha3
   kind: ClusterConfig
   metadata:
   spec:
     clusterName: my-cluster
     masterNodes:
       - nodeName: "g-master1"
         ip: 10.5.14.XX
         ansibleUser: "root"
         ansiblePass: "XXXX"
     fullPackagePath: "/home/offline"
     osRepos:
       type: builtin
       isoPath: "/home/uniontechos-server-20-1020a-amd64.iso" ## directory of ISO
       osPackagePath: "/home/os-pkgs-uos-20.tar.gz" ## directory of os-pkgs
     imagesAndCharts:
       type: builtin
     addonPackage:
       path: "/home/addon-offline-full-package-v0.5.3-alpha2-amd64.tar.gz" ## directory of addon
     binaries:
       type: builtin
   

7. Start the installation of DCE 5.0.

   ./dce5-installer cluster-create -m ./sample/manifest.yaml -c ./sample/clusterConfig.yaml
   

   Note

   Some parameters are introduced, and more parameters can be viewed through ./dce5-installer --help:

   • -z minimal install
   • -c specifies the cluster configuration file, and does not need to specify -c when using NodePort to expose the console
   • -d enable debug mode
   • --serial specifies that all installation tasks are executed serially

8. After the installation is complete, the command line will prompt that the installation is successful. Congratulations! Now you can use the default account and password (admin/changeme) to explore the new DCE 5.0 through the URL prompted on the screen!

   

   Success
