Introduction

Different users have different concerns. If you encounter problems, you are welcome to check the FAQ, submit an Issue, or ask the Community for help.

Beginners

Beginners can visit the Pigsty demo site: http://demo.pigsty.cc for a quick glance.

There are several data applications that are built upon Pigsty to illustrate this distribution: pglog, covid, isd, dbeng, worktime.

You can also deploy SaaS software with docker and get production-grade durability with an external pigsty database.

Developer

Developers are more concerned about the fastest way to download, install and access the database, please refer to Installation.

Pigsty aims at simplicity: you can launch pigsty on fresh CentOS 7.8 nodes with one command without Internet Access.

Pigsty provides Vagrant & Terraform templates for pulling up 4 VMs with one click to deploy a sandbox on a local x86 laptop/PC or cloud. Users can also prepare VMs, cloud VMs, or physical machines for the standard deployment process.

The user can access database service through connstr, and perform essential operation tasks with SOP.

For a deeper understanding of Pigsty’s design and architecture, you can refer to the concept chapter.
