Offline Installation

Pigsty installs from Internet upstream by default, but some envs are isolated from the Internet. To address this, Pigsty supports offline installation using offline packages. Think of them as Linux-native Docker images.

Overview

Offline packages bundle all required RPM/DEB packages and dependencies; they are snapshots of the local APT/YUM repo after a normal installation.

In serious prod deployments, we strongly recommend using offline packages. They ensure all future nodes have consistent software versions with the existing env, and avoid online installation failures caused by upstream changes (quite common!), guaranteeing you can run it independently forever.

Offline Packages

We typically release offline packages for the following Linux distros, using the latest OS minor version.

If you use an OS from the list above (exact minor version match), we recommend using offline packages. Pigsty provides ready-to-use pre-made offline packages for these systems, freely downloadable from GitHub.

You can download matching assets from the GitHub release page. The MD5 checksums for the v4.3.0 offline packages are:

Using Offline Packages

Offline installation steps:

1. Download Pigsty offline package, place it at /tmp/pkg.tgz
2. Download Pigsty source package, extract and enter directory (assume extracted to home: cd ~/pigsty)
3. ./bootstrap, it will extract the package and configure using local repo (and install ansible from it offline)
4. ./configure -g -c rich, you can directly use the rich template configured for offline installation, or configure yourself
5. Run ./deploy.yml as usual—it will install everything from the local repo

If you want to use the already extracted and configured offline package in your own config, modify and ensure these settings:

• repo_enabled: Set to true, will build local software repo (explicitly disabled in most templates)
• node_repo_modules: Set to local, then all nodes in the env will install from the local software repo
  • In most templates, this is explicitly set to: node,infra,pgsql, i.e., install directly from these upstream repos.
  • Setting it to local will use the local software repo to install all packages, fastest, no interference from other repos.
  • If you want to use both local and upstream repos, you can add other repo module names too, e.g., local,node,infra,pgsql

The first parameter, if enabled, Pigsty will create a local software repo. The second parameter, if contains local, then all nodes in the env will use this local software repo. If it only contains local, then it becomes the sole repo for all nodes. If you still want to install other packages from other upstream repos, you can add other repo module names too, e.g., local,node,infra,pgsql.

Hybrid Installation Mode

If your environment has Internet access, there’s a hybrid approach that combines the advantages of offline and online installation. You can use the offline package as a base, and supplement missing packages online.

For example, if you’re using RockyLinux 9.6 but the official offline package is for RockyLinux 9.7. You can use the el9 offline package (though made for 9.7), then execute make repo-build before formal installation to re-download missing packages for 9.6. Pigsty will download the required increments from upstream repos.

Making Offline Packages

If your OS isn’t in the default list, you can make your own offline package with the built-in cache.yml playbook:

1. Find a node running the exact same OS version with Internet access
2. Use rich config template to perform online installation (configure -c rich)
3. cd ~/pigsty; ./cache.yml: make and fetch the offline package to ~/pigsty/dist/${version}/
4. Copy the offline package to the env without Internet access (ftp, scp, usb, etc.), extract and use via bootstrap

We offer paid services providing tested, pre-made offline packages for specific Linux major.minor versions (¥200).

Bootstrap

Pigsty relies on ansible to execute playbooks; this script is responsible for ensuring ansible is correctly installed in various ways.

./bootstrap       # Ensure ansible is correctly installed (if offline package exists, use offline installation and extract first)

Usually, you need to run this script in two cases:

• You didn’t install Pigsty via the installation script, but by downloading or git clone of the source package, so ansible isn’t installed.
• You’re preparing to install Pigsty via offline packages and need to use this script to install ansible from the offline package.

The bootstrap script will automatically detect if the offline package exists (-p to specify, default is /tmp/pkg.tgz). If it exists, it will extract and use it, then install ansible from it. If the offline package doesn’t exist, it will try to install ansible from the Internet. If that still fails, you’re on your own!

./bootstrap -k # or --keep
