Module: NODE

Tune nodes into the desired state and monitor it, manage node, vip haproxy, and exporters.

Configuration | Administration | Playbook | Dashboard | Parameter


Concept

Node is an abstraction of hardware resources, which can be bare metal, virtual machines, or even k8s pods.

There are different types of nodes in Pigsty:

The admin node is usually overlapped with the infra node, if there’s more than one infra node, the first one is often used as the default admin node, and the rest of the infra nodes can be used as backup admin nodes.

Common Node

You can manage nodes with Pigsty, and install modules on them. The node.yml playbook will adjust the node to desired state.

Some services will be added to all nodes by default:

Component Port Description Status
Node Exporter 9100 Node Monitoring Metrics Exporter Enabled
HAProxy Admin 9101 HAProxy admin page Enabled
Promtail 9080 Log collecting agent Enabled
Docker Daemon 9323 Enable Container Service Disabled
Keepalived - Manage Node Cluster L2 VIP Disabled
Keepalived Exporter 9650 Monitoring Keepalived Status Disabled

Docker & Keepalived are optional components, enabled when required.

ADMIN Node

There is one and only one admin node in a pigsty deployment, which is specified by admin_ip. It is set to the local primary IP during configure.

The node will have ssh / sudo access to all other nodes, which is critical; ensure it’s fully secured.

INFRA Node

A pigsty deployment may have one or more infra nodes, usually 2 ~ 3, in a large production environment.

The infra group specifies infra nodes in the inventory. And infra nodes will have INFRA module installed (DNS, Nginx, Prometheus, Grafana, etc…),

The admin node is also the default and first infra node, and infra nodes can be used as ‘backup’ admin nodes.

Component Port Domain Description
Nginx 80 h.pigsty Web Service Portal (YUM/APT Repo)
AlertManager 9093 a.pigsty Alert Aggregation and delivery
Prometheus 9090 p.pigsty Monitoring Time Series Database
Grafana 3000 g.pigsty Visualization Platform

PushGateway 9091 - Collect One-Time Job Metrics
BlackboxExporter 9115 - Blackbox Probing
Dnsmasq 53 - DNS Server
Chronyd 123 - NTP Time Server
PostgreSQL 5432 - Pigsty CMDB & default database
Ansible - - Run playbooks

PGSQL Node

The node with PGSQL module installed is called a PGSQL node. The node and pg instance is 1:1 deployed. And node instance can be borrowed from corresponding pg instances with node_id_from_pg.

Component Port Description Status
Postgres 5432 Pigsty CMDB Enabled

Configuration

Each node has identity parameters that are configured through the parameters in <cluster>.hosts and <cluster>.vars.

Pigsty uses IP as a unique identifier for database nodes. This IP must be the IP that the database instance listens to and serves externally, But it would be inappropriate to use a public IP address!

This is very important. The IP is the inventory_hostname of the host in the inventory, which is reflected as the key in the <cluster>.hosts object.

You can use ansible_* parameters to overwrite ssh behavior, e.g. connect via domain name / alias, but the primary IPv4 is still the core identity of the node.

nodename and node_cluster are not mandatory; nodename will use the node’s current hostname by default, while node_cluster will use the fixed default value: nodes.

If node_id_from_pg is enabled, the node will borrow PGSQL identity and use it as Node’s identity, i.e. node_cluster is set to pg_cluster if applicable, and nodename is set to ${pg_cluster}-${pg_seq}. If nodename_overwrite is enabled, node’s hostname will be overwritten by nodename

Pigsty labels a node with identity parameters in the monitoring system. Which maps nodename to ins, and node_cluster into cls.

Name Type Level Necessity Comment
inventory_hostname ip - Required Node IP
nodename string I Optional Node Name
node_cluster string C Optional Node cluster name

The following cluster config declares a three-node node cluster:

node-test:
  hosts:
    10.10.10.11: { nodename: node-test-1 }
    10.10.10.12: { nodename: node-test-2 }
    10.10.10.13: { nodename: node-test-3 }
  vars:
    node_cluster: node-test

Default values:

#nodename:           # [INSTANCE] # node instance identity, use hostname if missing, optional
node_cluster: nodes   # [CLUSTER] # node cluster identity, use 'nodes' if missing, optional
nodename_overwrite: true          # overwrite node's hostname with nodename?
nodename_exchange: false          # exchange nodename among play hosts?
node_id_from_pg: true             # use postgres identity as node identity if applicable?

Administration

Here are some common administration tasks for NODE module.


Add Node

To add a node into Pigsty, you need to have nopass ssh/sudo access to the node

# ./node.yml -l <cls|ip|group>        # the underlying playbook
# bin/node-add <selector|ip...>       # add cluster/node to pigsty
bin/node-add node-test                # init node cluster 'node-test'
bin/node-add 10.10.10.10              # init node '10.10.10.10'

Remove Node

To remove a node from Pigsty, you can use the following:

# ./node-rm.yml -l <cls|ip|group>    # the underlying playbook
# bin/node-rm <selector|ip...>       # remove node from pigsty:
bin/node-rm node-test                # remove node cluster 'node-test'
bin/node-rm 10.10.10.10              # remove node '10.10.10.10'

Create Admin

If the current user does not have nopass ssh/sudo access to the node, you can use another admin user to bootstrap the node:

node.yml -t node_admin -k -K -e ansible_user=<another admin>   # input ssh/sudo password for another admin 

Bind VIP

You can bind an optional L2 VIP on a node cluster with vip_enabled.

proxy:
  hosts:
    10.10.10.29: { nodename: proxy-1 } 
    10.10.10.30: { nodename: proxy-2 } # , vip_role: master }
  vars:
    node_cluster: proxy
    vip_enabled: true
    vip_vrid: 128
    vip_address: 10.10.10.99
    vip_interface: eth1
./node.yml -l proxy -t node_vip     # enable for the first time
./node.yml -l proxy -t vip_refresh  # refresh vip config (e.g. designated master)

Pigsty NODE module frequently asked questions

How to configure NTP service?

If NTP is not configured, use a public NTP service or sync time with the admin node.

If your nodes already have NTP configured, you can leave it there by setting node_ntp_enabled to false.

Otherwise, if you have Internet access, you can use public NTP services such as pool.ntp.org.

If you don’t have Internet access, at least you can sync time with the admin node with the following:

node_ntp_servers:                 # NTP servers in /etc/chrony.conf
  - pool cn.pool.ntp.org iburst
  - pool ${admin_ip} iburst       # assume non-admin nodes do not have internet access

How to force sync time on nodes?

Use chronyc to sync time. You have to configure the NTP service first.

ansible all -b -a 'chronyc -a makestep'     # sync time

You can replace all with any group or host IP address to limit execution scope.


Remote nodes are not accessible via SSH commands.

Consider using Ansible connection parameters if the target machine is hidden behind an SSH springboard machine, or if some customizations have been made that cannot be accessed directly using ssh ip. Additional SSH ports can be specified with ansible_port or ansible_host for SSH Alias.

pg-test:
  vars: { pg_cluster: pg-test }
  hosts:
    10.10.10.11: {pg_seq: 1, pg_role: primary, ansible_host: node-1 }
    10.10.10.12: {pg_seq: 2, pg_role: replica, ansible_port: 22223, ansible_user: admin }
    10.10.10.13: {pg_seq: 3, pg_role: offline, ansible_port: 22224 }

Password required for remote node SSH and SUDO

When performing deployments and changes, the admin user used must have ssh and sudo privileges for all nodes. Password-free is not required.

You can pass in ssh and sudo passwords via the -k|-K parameter when executing the playbook or even use another user to run the playbook via -eansible_host=<another_user>. However, Pigsty strongly recommends configuring SSH passwordless login with passwordless sudo for the admin user.


Create an admin user with the existing admin user.

This will create an admin user specified by node_admin_username with the existing one on that node.

./node.yml -k -K -e ansible_user=<another_admin> -t node_admin`

Exposing node services with HAProxy

You can expose service with haproxy_services in node.yml.

And here’s an example of exposing MinIO service with it: Expose MinIO Service


Why my nodes /etc/yum.repos.d/* are nuked?

Pigsty will try to include all dependencies in the local yum repo on infra nodes. This repo file will be added according to node_repo_modules. And existing repo files will be removed by default according to the default value of node_repo_remove. This will prevent the node from using the Internet repo or some stupid issues.

If you want to keep existing repo files during node init, just set node_repo_remove to false.

If you want to keep existing repo files during infra node local repo bootstrap, just set repo_remove to false.


Why my shell prompt change and how to restore it?

The pigsty prompt is defined with the environment variable PS1 in /etc/profile.d/node.sh.

To restore your existing prompt, just remove that file and login again.
