Installation

Install Pigsty with 4 steps: Prepare, Download, Configure and Install. Also check offline if you don’t have internet access.

Short Version

Prepare a fresh x86_64/aarch64 node that runs any compatible Linux OS Distros, then Download Pigsty with:

curl -fsSL https://repo.pigsty.io/get | bash; cd ~/pigsty;

You can run the optional bootstrap and configure to install ansible and generate pigsty.yml config file.

Next, run the install.yml playbook with an admin user (nopass ssh & sudo):

./bootstrap; ./configure; ./install.yml;

• bootstrap: OPTIONAL, make sure ansible is installed, and use offline package /tmp/pkg.tgz if applicable
• configure: OPTIONAL, recommend & generate pigsty.yml config according to your env.
• install.yml: REQUIRED, install Pigsty modules according to your config file.

It may take several minutes to complete the installation according to your network speed and hardware spec.

After that, you will get a pigsty singleton node ready, with Web service on port 80/443 and Postgres on port 5432.

BTW: If you feel Pigsty is too complicated, you can consider the Slim Installation, which only installs the necessary components for HA PostgreSQL clusters.

Example: Singleton Installation on RockyLinux 9.3:

Prepare

Check Preparation for a complete guide of resource preparation.

Pigsty support the Linux kernel and x86_64/aarch64 arch. It can run on any nodes: physical machine, bare metal, virtual machines, or VM-like containers, but a static IPv4 address is required. The minimum spec is 1C1G. It is recommended to use bare metals or VMs with at least 2C4G. There’s no upper limit, and node param will be auto-tuned.

We recommend using fresh RockyLinux 8.10 / 9.4 or Ubuntu 22.04 as underlying operating systems. For a complete list of supported operating systems, please refer to Compatibility.

Public key ssh access to localhost and NOPASSWD sudo privilege is required to perform the installation, Try not using the root user. If you wish to manage more nodes, these nodes needs to be ssh / sudo accessible via your current admin node & admin user.

Pigsty relies on Ansible to execute playbooks. you have to install ansible and jmespath packages fist before install procedure. This can be done with the following command, or through the bootstrap procedure, especially when you don’t have internet access.

• Install Ansible
• EL 8 / 9
• EL 7
• Debian / Ubuntu
• MacOS

sudo dnf install -y ansible python3.12-jmespath python3-cryptography

sudo yum install -y ansible   # EL7 does not need to install jmespath explicitly

sudo apt install -y ansible python3-jmespath

brew install ansible

To install a specific version, pass the version string as the first parameter:

curl -fsSL https://repo.pigsty.io/get | bash -s v3.1.0; cd ~/pigsty

You can also use git to download the Pigsty source. Please make sure to check out a specific version before using.

git clone https://github.com/Vonng/pigsty; cd pigsty; git checkout v3.1.0

Configure

configure will create a pigsty.yml config file according to your env. This procedure is OPTIONAL if you know how to configure pigsty manually. There are many config tempalte for your reference.

./configure # interactive-wizard, ask for IP address
./configure [-i|--ip <ipaddr>]                     # give primary IP & config mode
            [-c|--conf <conf>]                     # specify config template (relative to conf/ dir without .yml suffix)
            [-v|--version <ver>]                   # specify PostgreSQL major version (13,14,15,16,17)
            [-r|--region <default|china|europe>]   # choose upstream repo region
            [-n|--non-interactive]                 # skip interactive wizard
            [-x|--proxy]                           # write proxy env to config 

$ ./configure

proceed with ./install.yml

• -i|--ip: Replace IP address placeholder 10.10.10.10 with your primary ipv4 address of current node.
• -c|--conf: Generate config from config templates according to this parameter
• -v|--version: Specify PostgreSQL major version (13|14|15|16|17)
• -r|--region: Set upstream repo mirror according to region (default|china|europe)
• -n|--non-interactive: skip interactive wizard and using default/arg values
• -x|--proxy: write current proxy env to the config proxy_env (http_proxy/HTTP_PROXY, HTTPS_PROXY, ALL_PROXY, NO_PROXY)

When -n|--non-interactive is specified, you have to specify a primary IP address with -i|--ip <ipaddr> in case of multiple IP address, since there’s no default value for primary IP address in this case.

If your machine’s network interface have multiple IP addresses, you’ll need to explicitly specify a primary IP address for the current node using -i|--ip <ipaddr>, or provide it during interactive inquiry. The address should be a static IP address, and you should avoid using any public IP addresses.

You can check and modify the generated config file ~/pigsty/pigsty.yml before installation.

Install

Run the install.yml playbook to perform a full installation on current node

./install.yml    # install everything in one-pass

[vagrant@meta pigsty]$ ./install.yml

It’s a standard ansible playbook, you can have fine-grained control with ansible options:

• -l: limit execution targets
• -t: limit execution tasks
• -e: passing extra args
• -i: use another config
• …

Interface

Once installed, you’ll have four core modules PGSQL, INFRA, NODE, and ETCD the current node.

The PGSQL provides a PostgreSQL singleton which can be accessed via:

• Default Users
• dbuser_dba
• dbuser_meta
• dbuser_view

psql postgres://dbuser_dba:[email protected]/meta     # DBA / superuser (via IP)

psql postgres://dbuser_meta:[email protected]/meta   # business admin, read / write / ddl

psql postgres://dbuser_view:DBUser.View@pg-meta/meta       # read-only user

The INFRA module gives you an entire modern observability stack, exposed by Nginx on (80 / 443):

There are several services are exposed by Nginx (configured by infra_portal):

Grafana Dashboards (g.pigsty, port 3000) credentials, user: admin / pass: pigsty

You can access these web UI directly via IP + port. While the common best practice would be access them through Nginx and distinguish via domain names. You’ll need configure DNS records, or use the local static records (/etc/hosts) for that.

<your_public_ip_address>  h.pigsty a.pigsty p.pigsty g.pigsty

http://g.pigsty ️-> http://10.10.10.10:80 (nginx) -> http://10.10.10.10:3000 (grafana)

More

You can deploy & monitor more clusters with pigsty: add more nodes to pigsty.yml and run corresponding playbooks:

bin/node-add   pg-test      # init 3 nodes of cluster pg-test
bin/pgsql-add  pg-test      # init HA PGSQL Cluster pg-test
bin/redis-add  redis-ms     # init redis cluster redis-ms

Remember that most modules require the NODE module installed first. Check modules for detail
