## Get Started
[](https://pigsty.io/docs/pgsql)
[](https://pigsty.io/docs/node)
[](https://ext.pigsty.io/#/rpm)
[](https://pigsty.io/docs/reference/compatibility/)
[](https://ext.pigsty.io/#/deb)
[](https://almalinux.org/)
[](https://almalinux.org/)
[](https://almalinux.org/)
[](https://almalinux.org/)
[**Prepare**](https://pigsty.io/docs/setup/prepare/) a fresh **x86_64** node that runs any [**compatible**](https://pigsty.io/docs/reference/compatibility/) **Linux** OS Distros, then [**Download**](https://pigsty.io/docs/setup/install/) **Pigsty** with:
```bash
curl -fsSL https://repo.pigsty.io/get | bash; cd ~/pigsty;
```
Next, [**bootstrap**](https://pigsty.io/docs/setup/offline/#bootstrap), [**configure**](https://pigsty.io/docs/setup/install#configure), and run the [**`install.yml`**](https://pigsty.io/docs/setup/install#install) playbook with an [**admin user**](https://pigsty.io/docs/setup/prepare/#admin-user) (**nopass** `ssh` & `sudo`):
```bash
./bootstrap; ./configure; ./install.yml;
```
Finally, you will get a pigsty singleton node [**ready**](https://pigsty.io/docs/setup/install/#interface), with Web service on port `80/443` and Postgres on port `5432`.
> Consider [**Minimal Installation**](https://pigsty.io/docs/setup/mini/) if you only want essential components for HA PostgreSQL.
Install with get script

## Architecture
Pigsty uses a [**modular**](https://pigsty.io/docs/concept/arch/) design. There are **4** **CORE** [**modules**](https://pigsty.io/docs/about/module/) available by default:
[](https://pigsty.io/docs/pgsql) Self-healing PostgreSQL HA cluster powered by Patroni, Pgbouncer, PgBackrest & HAProxy
[](https://pigsty.io/docs/infra) Nginx, Local Repo, DNSMasq, and the entire Prometheus & Grafana observability stack.
[](https://pigsty.io/docs/node) Init node name, repo, pkg, NTP, ssh, admin, tune, expose services, collect logs & metrics.
[](https://pigsty.io/docs/etcd) Etcd cluster is used as a reliable distributive configuration store by PostgreSQL HA Agents.
You can compose them freely in a declarative manner. `INFRA` & `NODE` will suffice for host monitoring.
`ETCD` and `PGSQL` are used for HA PG clusters; Installing them on multiple nodes automatically forms HA clusters.
The default [`install.yml`](https://github.com/Vonng/pigsty/blob/main/install.yml) playbook will install `INFRA`, `NODE`, `ETCD` & `PGSQL` on the current node.
Which gives you an out-of-the-box PostgreSQL singleton instance (`admin_ip:5432`) with everything ready.
[](https://pigsty.io/docs/concept/arch/)
The node can be used as an admin controller to deploy & monitor more nodes & clusters. For example, you can install these **4** **OPTIONAL** [extended modules](https://pigsty.io/docs/about/module/#extended-modules) for advanced use cases:
[](https://pigsty.io/docs/etcd) S3-compatible object storage service; used as an optional central backup server for `PGSQL`.
[](https://pigsty.io/docs/infra) Deploy Redis servers in standalone master-replica, sentinel, and native cluster mode.
[](https://pigsty.io/docs/ferret) Native support for FerretDB — adding MongoDB wire protocol compatibility to Postgres!
[](https://pigsty.io/docs/docker) Launch optional docker daemons to run other stateless parts besides Pigsty RDS.
Of course, you can deploy different kinds of HA **PostgreSQL** clusters on multiple nodes, as much as you want.
----------------
## PostgreSQL RDS
To deploy an additional 3-node HA Postgres cluster `pg-test`. Add the cluster [**definition**](https://github.com/Vonng/pigsty/blob/main/conf/sandbox/full.yml#L46) to the [**config inventory**](https://pigsty.io/docs/setup/config/):
```yaml
pg-test:
hosts:
10.10.10.11: { pg_seq: 1, pg_role: primary }
10.10.10.12: { pg_seq: 2, pg_role: replica }
10.10.10.13: { pg_seq: 3, pg_role: offline }
vars:
pg_cluster: pg-test
```
The default config file is [`pigsty.yml`](https://github.com/Vonng/pigsty/blob/main/pigsty.yml) under pigsty home, add the snippet above to the `all.children.pg-test`,
Then, create the cluster with built-in playbooks in one command:
```bash
bin/pgsql-add pg-test # init pg-test cluster
```
Example: Complex PostgreSQL Customization
This config file provides a detailed example of a complex PostgreSQL cluster `pg-meta` with multiple databases, users, and service definition:
```yaml

It will create a cluster with everything properly configured: [**High Availability**](https://pigsty.io/docs/concept/ha) powered by patroni & etcd; [**Point-In-Time-Recovery**](https://pigsty.io/docs/concept/pitr) powered by pgBackRest & optional MinIO / S3;
auto-routed, pooled [**Services & Access**](https://pigsty.io/docs/concept/svc#default-service) pooled by pgBouncer and exposed by haproxy; and out-of-the-box [**Monitoring**](https://pigsty.io/docs/pgsql/dashboard/) & alerting powered by the **`INFRA`** module.
[](https://pigsty.io/docs/concept/ha/)
The cluster keeps serving as long as **ANY** instance survives, with excellent fault-tolerance performance:
> [**RPO**](https://pigsty.io/docs/concept/ha#rpo) **= 0** on sync mode, **RPO < 1MB** on async mode; [**RTO**](https://pigsty.io/docs/concept/ha#rpo) **< 1s** on switchover, **RTO ≈ 15s** on failover.
----------------
## Customization
Pigsty is highly customizable, You can describe the entire database and infra deployment with **300+** [**parameters**](https://pigsty.io/docs/pgsql/conf/) in a single config file and materialize them with one command.
Example: Sandbox (4-node) with two PG cluster
The [`full.yml`](https://github.com/Vonng/pigsty/blob/main/conf/sandbox/full.yml) utilize four nodes to deploy two PostgreSQL clusters `pg-meta` and `pg-test`:
```yaml
pg-meta:
hosts: { 10.10.10.10: { pg_seq: 1, pg_role: primary } }
vars:
pg_cluster: pg-meta
pg_users:
- {name: dbuser_meta ,password: DBUser.Meta ,pgbouncer: true ,roles: [dbrole_admin] ,comment: pigsty admin user }
- {name: dbuser_view ,password: DBUser.Viewer ,pgbouncer: true ,roles: [dbrole_readonly] ,comment: read-only viewer for meta database }
pg_databases:
- {name: meta ,baseline: cmdb.sql ,comment: pigsty meta database ,schemas: [pigsty]}
pg_hba_rules:
- {user: dbuser_view , db: all ,addr: infra ,auth: pwd ,title: 'allow grafana dashboard access cmdb from infra nodes'}
pg_vip_enabled: true
pg_vip_address: 10.10.10.2/24
pg_vip_interface: eth1
# pgsql 3 node ha cluster: pg-test
pg-test:
hosts:
10.10.10.11: { pg_seq: 1, pg_role: primary } # primary instance, leader of cluster
10.10.10.12: { pg_seq: 2, pg_role: replica } # replica instance, follower of leader
10.10.10.13: { pg_seq: 3, pg_role: replica, pg_offline_query: true } # replica with offline access
vars:
pg_cluster: pg-test # define pgsql cluster name
pg_users: [{ name: test , password: test , pgbouncer: true , roles: [ dbrole_admin ] }]
pg_databases: [{ name: test }]
pg_vip_enabled: true
pg_vip_address: 10.10.10.3/24
pg_vip_interface: eth1
```
You can even deploy PostgreSQL with different major versions and kernel forks in the same deployment:
[](https://pigsty.io/img/pigsty/kernels.jpg)
Example: Security Setup & Delayed Replica
The following [`conf/demo/security.yml`](https://github.com/Vonng/pigsty/blob/main/conf/demo/security.yml) provision a 3-node [security](https://pigsty.io/docs/setup/security/) enhanced postgres cluster `pg-meta` with a delayed replica `pg-meta-delay`:
```yaml
pg-meta: # 3 instance postgres cluster `pg-meta`
hosts:
10.10.10.10: { pg_seq: 1, pg_role: primary }
10.10.10.11: { pg_seq: 2, pg_role: replica }
10.10.10.12: { pg_seq: 3, pg_role: replica , pg_offline_query: true }

pg_cluster: pg-meta
pg_conf: crit.yml

You can deploy different kinds of PostgreSQL instance such as primary, replica, offline, delayed, sync standby, etc.,
and customize with scene-optimize [**templates**](https://github.com/Vonng/pigsty/tree/dev/conf), pre-defined [**stacks**](https://pigsty.io/docs/pgext/usage/stack) and all **345** [**extensions**](https://ext.pigsty.io/#/list).
[](https://ext.pigsty.io/)
You can define [**Users**](https://pigsty.io/docs/pgsql/user/), [**Databases**](https://pigsty.io/docs/pgsql/db/), [**Service**](https://pigsty.io/docs/pgsql/svc/), [**HBAs**](https://pigsty.io/docs/pgsql/hba/) and other entities in code and provision them in one pass.
You can even replace the vanilla [**`PostgreSQL`**](https://pigsty.io/docs/pgsql) [**Kernel**](https://pigsty.io/docs/kernel/) with other forks as an in-place replacement: [**`Babelfish`**](https://pigsty.io/docs/kernel/babelfish/) for MSSQL compatibility,
[**`IvorySQL`**](https://pigsty.io/docs/kernel/ivorysql) and [**`PolarDB`**](https://pigsty.io/docs/kernel/polardb/) for ORACLE compatibility:

You can also wrap existing kernel with add-ons: horizontal sharding with [**`CITUS`**](https://pigsty.io/docs/kernel/citus/),
serving MongoDB wire protocol with [**`FERRET`**](https://pigsty.io/docs/ferret/), or self-hosting firebase alternative with [**`SUPABASE`**](https://pigsty.io/docs/kernel/supabase/):
