Step‑by‑Step Guide to Deploy UCloud’s Free USDP for Big Data

USDP Free Version Deployment Guide

UCloud recently released a free version of USDP for private deployment, supporting HDFS, Kudu, and Elasticsearch ecosystems. This guide shows how to prepare the environment, download resources, configure nodes, and install the platform.

1. Environment Preparation

Minimum deployment requires three nodes. Recommended configuration per node: 4 CPU cores, 8 GB memory, 80 GB system disk, 500 GB data disk, CentOS 7.2‑7.6. Nodes can be physical or virtual.

2. Resource Download

Download the package from US3 or Baidu Netdisk (extraction code: spp9). The main package usdp-01-master-privatization-free-1.0.0.0.tar.gz contains the following directories:

agent          – distributed client program
bin            – start/stop scripts
config         – configuration files
jmx_exporter   – process monitoring exporter
recommend      – deployment templates
repair         – initialization scripts and resources
repository     – big‑data service resources
scripts        – auxiliary scripts
server         – management server program
sql            – metadata initialization SQL
templated      – service configuration templates
verify         – certificate storage
versions       – version information

3. Deployment Steps

3.1 Environment Initialization

Edit repair.properties and repair-host-info.properties to specify YUM source host, NMAP, NTP, MySQL nodes, and other parameters. Example snippets are provided.

Run the one‑click initialization script:

cd /opt/usdp-srv/usdp/repair/sbin
bash repair.sh initAll
source /etc/profile

3.2 Start USDP Server

bin/start-udp-server.sh

3.3 Access Web UI

Open http://<server_ip>:80 in a browser, set the administrator password on first login, and upload the free‑edition license obtained from http://117.50.84.208:8002/licenseManagement/generate.

4. Appendix – Manual Environment Setup

If automatic initialization is not used, install required YUM packages, MySQL 5.7, JDK, adjust system limits, disable SELinux, firewalls, swap, configure SSH key‑less login, NTP, and other kernel settings as described.
