    ClickHouse - Hardened Open-Source Columnar OLAP Database

     Info

    This product has charges associated with it for hardening, security configuration, and support. ClickHouse is an open-source column-oriented OLAP database written in C++ for real-time analytics on billions of rows. Unlike bare ClickHouse AMIs that ship with an empty password for the default user, expose ports 8123 and 9000 to the world with no authentication, and apply no OS hardening, this Lynxroute build is ready out of the box: a strong random password generated at first boot and stored as SHA-256 hex, UFW firewall pre-configured, fail2ban and AppArmor enabled, and a CIS Level 1 hardened Ubuntu 24.04 LTS base. Apache-2.0 license - fully auditable, no vendor lock-in.

    Overview

    This is a repackaged software product wherein additional charges apply for hardening, security configuration, and support.

    WHAT IS CLICKHOUSE

    ClickHouse is an open-source column-oriented online analytical processing (OLAP) database management system written in C++ and distributed as a single compiled native binary. It is designed for low-latency analytical queries over very large tables: aggregations, time-series rollups, ad-hoc SQL on billions of rows. Features include the MergeTree storage engine with automatic part merges and partitioning, distributed and replicated tables for horizontal scale-out, materialized views, dictionaries, projections, an HTTP REST API on port 8123, a fast native binary protocol on port 9000, and a built-in web SQL console at /play. SQL is extended with array, tuple, nested, JSON, and IPv4/IPv6 types. Standard ODBC and JDBC drivers and client libraries for most popular languages are available. Data is persisted on local disk under /var/lib/clickhouse - no external database required for single-node deployments. Apache-2.0 license, no vendor lock-in. A self-hosted alternative to proprietary cloud data warehouses for hot-data analytics, keeping all data inside your own AWS account.

    WHAT THIS AMI ADDS

    Security hardening:

    • Strong random 32-character password generated per instance at first boot for the ClickHouse default user
    • Password stored only as SHA-256 hex in users.d drop-in - never written in plain text inside the AMI
    • UFW firewall pre-configured - ports 8123 and 9000 open externally for buyer use, port 22 for SSH; all other inbound traffic dropped
    • fail2ban, AppArmor enabled
    • CVE scan - every image is scanned for vulnerabilities before release

    OS hardening (CIS Level 1):

    • CIS Ubuntu 24.04 LTS Level 1 benchmark applied via ansible-lockdown
    • auditd, SSH hardening (key-only, PermitRootLogin no, LoginGraceTime 60), Kernel hardening (ASLR, reverse path filtering, SYN cookies, kexec disabled, IPv6 off), IMDSv2 enforced

    Compliance artifacts:

    • SBOM - CycloneDX 1.6 at /etc/lynxroute/sbom.json
    • CIS Conformance Report at /etc/lynxroute/cis-report.html
    • CIS Tailored Profile at /usr/share/doc/lynxroute/CIS_TAILORED_PROFILE.md

    Highlights

    • ClickHouse security baked in: strong random password for the default user generated at first boot and stored as SHA-256 hex, UFW firewall pre-configured, fail2ban and AppArmor enabled - unlike bare ClickHouse AMIs that ship with an empty default-user password, expose HTTP and native ports with no authentication, and leave the OS unhardened.
    • CIS Level 1 hardened Ubuntu 24.04 LTS: auditd, fail2ban, AppArmor, SSH key-only, IMDSv2 enforced. CVE-scanned before every release. SBOM (CycloneDX) and CIS Conformance Report included.
    • Self-hosted hot-data analytics: sub-second SQL queries over billions of rows, MergeTree storage, HTTP and native protocols, built-in /play web SQL console. Apache-2.0 license - no vendor lock-in, no per-query pricing.

    Amazon Machine Image (AMI)

    An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

    Additional details

    Usage instructions

    1. Launch instance (t3.xlarge recommended; t3.large minimum, m6i.xlarge or larger for production)
    2. Open Security Group - allow TCP 8123 and TCP 9000 from your IP only
    3. SSH: ssh -i key.pem ubuntu@<PUBLIC_IP>
    4. Read credentials: sudo cat /root/clickhouse-credentials.txt
    5. Test the HTTP API: curl -u "default:<password>" "http://<PUBLIC_IP>:8123/?query=SELECT+version()"
    6. Open the web SQL console: http://<PUBLIC_IP>:8123/play - log in as user "default" with the password from the credentials file
    7. Connect via native protocol from your workstation: clickhouse-client --host <PUBLIC_IP> --password "<password>" --query "SELECT 1"

    The default-user password is generated at first boot and saved to /root/clickhouse-credentials.txt (mode 600). For production use, restrict TCP 8123 and 9000 to trusted IPs (never 0.0.0.0/0) and terminate TLS in a reverse proxy in front of the HTTP endpoint. Data is persisted at /var/lib/clickhouse - for production attach a dedicated gp3 EBS volume mounted there for higher IOPS.
