Grafana – Install Loki

A Loki-based logging stack consists of 3 components:

  • Promtail is the agent, responsible for gathering logs and sending them to Loki.
  • Loki is the main server, responsible for storing logs and processing queries.
  • Grafana for querying and displaying the logs.
wget https://github.com/grafana/loki/releases/download/v2.9.8/loki-linux-amd64.zip
chmod a+x loki-linux-amd64
sudo cp loki-linux-amd64 /usr/local/bin/loki

Grafana – Monitor các thiết bị

Ở các bài trước ta đã setup được cơ bản server cho web hosting, gatekeeper. Vậy post này ta setup Grafana trên `gatekeeper` để monitor các server(s).

Đầu tiên là install Grafana . Cái này quite simple chỉ cần follow up guide trên website của hãng là okay. By default Grafana sử dụng port 3000

Sau đó install Prometheus

  • Setup Group & User
sudo groupadd prometheus
sudo useradd -s /sbin/nologin --system -g prometheus prometheus
  • Setup các directories cần thiết
sudo mkdir /etc/prometheus
sudo mkdir /var/lib/prometheus

Directory “““/var/lib/prometheus sẽ dùng chứa data do đó suggest store trên HDD thay vì SSD chính để bảo toàn tuổi thọ cho SSD, cũng như không làm ảnh hưởng performance của SSD cho các việc khác liên quan tới OS.

Do đó trong case này mình chuyển về /mnt/data

sudo mkdir /mnt/data/prometheus

Latest version hiện tại là 2.52.02 / 2024-05-07

mkdir -p /tmp/prometheus
cd /tmp/prometheus
curl -s https://api.github.com/repos/prometheus/prometheus/releases/latest | grep browser_download_url | grep linux-amd64 | cut -d '"' -f 4 | wget -qi -
tar xvf prometheus*.tar.gz
cd prometheus*/

Tiếp theo là cd vào directory vừa unzip ra và move binaries về “`/usr/local/bin

sudo mv prometheus /usr/local/bin
sudo mv promtool /usr/local/bin
sudo chown prometheus:prometheus /usr/local/bin/prometheus
sudo chown prometheus:prometheus /usr/local/bin/promtool

Sau đó tạo file config ( ở directory song song với data )

sudo mv consoles /etc/prometheus
sudo mv console_libraries /etc/prometheus
sudo mv prometheus.yml /etc/prometheus
  • Tạo Systemd Service

[Install]
WantedBy=multi-user.target

https://prometheus.io/docs/prometheus/latest/command-line/prometheus

Chú ý thay đổi path phù hợp

Enable service khi boot và start

sudo systemctl daemon-reload
sudo systemctl enable prometheus.service
sudo systemctl start prometheus.service
sudo systemctl status prometheus.service

Như vậy là xong. Prometheus sẽ chạy ở port 9090

Thực tế https://prometheus.jooservices.com

Ở các bài tiếp theo sẽ setup tiếp các exporters / loki

Gatekeep server with Syslog-NG

Em gatekeep được hiểu như gác cổng của toàn bộ thiết bị sau đó, do đó nó cũng phải monitoring mọi thứ. Syslog-NG là một trong những services cần thiết

  • Router sẽ bắn syslog về
  • Core Switch cũng sẽ bắn syslog về
  • Cuối cùng là các AP cũng vậy
  • …. và bất kì thiết bị nào khác cũng sẽ tương tự

Sự khác biệt giữa syslog / syslog-ng & rsyslog

https://serverfault.com/questions/692309/what-is-the-difference-between-syslog-rsyslog-and-syslog-ng

Đầu tiên là phải enable UDP port 514 để nhận syslog từ ngoài vào. Mấy món này sẽ easily hơn với Webmin UI.

Vậy là SyslogNG đã ready. Tuy nhiên cần lưu ý kiểm port 514 UDP đã được enable ( most of case thì Webmin sẽ install luôn firewall và tất nhiên port này không được enabled )

Tuy nhiên log là thứ … write liên tục. Do đó giảm thiểu cái nào được ra khỏi SSD thì tốt bấy nhiêu.

  • Log sources : Các nguồn cung cấp logs . Ở đây mình đã thêm s_net
  • Log destination : Store logs vào đâu
  • Log filter : Lọc các logs
  • Và cuối cùng là kết hợp mọi thứ để tạo log : Log từ source nào – Filter thế nào & Save vào đâu

HAProxy server

Ở bài trước mình đã có 1 con server selfhosted dành cho web server. Tuy nhiên homelab này mình sẽ có nhiều server do đó sẽ cần 1 em đóng vai trò gateway ( cũng như monitoring )

  • i5-8700
  • 32GB RAM – 2666Mhz
  • SSD NVme Gen3 x4 : 256GB
  • HDD Sata : 1TB

Sau khi setup xong Ubuntu server như ở bài trước ( không cần Virtualmin ) thì ở server này sẽ cần HAProxy

HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.

Mục đích sử dụng HAProxy để forward request về các servers / services cần thiết. Ví dụ

  • https://selfhosted.jooservices.com/ sẽ được forward về Virtualmin ( port 10000 ) ở server selfhosted ta vừa installed trước.
  • https://jooservices.com sẽ forward về port 443 ( SSL ) của Virtualmin và load website

Cấu hình HAProxy

# HAProxy Stats
listen  stats
        bind *:1936
        log global

        maxconn 10

        stats enable
        stats show-node

        http-request use-service prometheus-exporter if { path /metrics }
        stats uri  /stats

Bật HAProxy stats để quản lý

Tạm gác qua Sentry & Grafana ta sẽ nói sau. Thì ta có FE SSL cho các services

  • cnmatrix.jooservices.com : Trỏ về Core switch port 443
  • gatekeeper.jooservices.com : Trỏ về con server này với Webmin ( không phải Virtualmin ) trên port 10000
  • jooservices.com && xcrawler.net cùng nằm trên selfhosted server với port 443

Và sau đó là config BE để forward về server / port tương tứng với từng FE

[Part 1] Ubuntu server for web hosting

Bài đầu tiên trong series là Setup 1 con Ubuntu server.

Mình có 1 con HP EliteDesk 800 G2 với

  • i5-6400
  • 32GB RAM – 2666Mhz
  • SSD NVme Gen3 x4 : 256GB
  • SSD Sata : 120GB

OS

Read more: [Part 1] Ubuntu server for web hosting

Oki sau khi installed OS xong. Ta có 1 vài thứ cơ bản

Update /etc/sudoers và thêm vào cuối file

$USER ALL=(ALL) NOPASSWD:ALL
  • Update LVM 100% Storage
  • Update NTP & Timezone
curl -L https://raw.githubusercontent.com/jooservices/bash/main/services/vm | bash

Oki để hosting ta sẽ dùng Virtualmin.

Virtualmin is the leading and most sophisticated web hosting control panel designed for Linux systems.

Virtualmin

By default Virtualmin không có đủ hết các PHP versions do đó ta sẽ install thêm

curl -L https://raw.githubusercontent.com/jooservices/bash/main/services/multi-php.sh | bash

Cơ bản 1 con web hosting như vậy là đủ. Một số packages bổ sung tùy chọn

By default Webmin / Virtualmin sẽ enable firewall. Do đó nếu cần access từ ngoài vào với các 3rd party services / ports thì cần update rules

Live site : https://selfhosted.jooservices.com

Để setup domain / Cloudflare trỏ về Virtualmin ta sẽ dùng HAProxy ở bài sau
