What sh is

Bash-based automation suite covering system diagnostics (CPU, memory, disk, bandwidth), network testing (speedtest, latency, packet loss), Docker container orchestration with custom commands, LNMP (Nginx/MySQL/PHP) stack provisioning, WAF/anti-CC defense, BBR congestion control, and scheduled backup/migration workflows across Debian, CentOS, Alpine, Arch, and others.

Quickstart

Get the sh source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/kejilion/sh.gitcd sh# follow the project's README for install & configuration

Best use cases

VPS/Server Initial Setup & Hardening

Rapidly provision fresh Linux instances with system monitoring, Docker, web stack, and firewall configuration in a single execution, reducing manual configuration time for development and production environments.

Rapid LNMP Deployment for Web Properties

Accelerate Nginx + MySQL + PHP site deployment with one-click installation, including SSL, caching, and anti-DDoS/bot rules pre-configured for small-to-medium web applications.

Linux System Administration Across Heterogeneous Fleets

Unify management of Ubuntu, Debian, CentOS, and Rocky Linux systems with consistent tooling for backups, Docker provisioning, network tuning, and performance diagnostics without distributing separate scripts.

Implementation considerations

  • Remote execution pattern (bash <(curl -sL kejilion.sh)) carries inherent supply-chain risk; validate script integrity offline and review before deployment on production systems.
  • Supports 10 Linux distros but behavior varies by package manager (apt vs. yum), kernel version, and systemd configuration; test thoroughly on target OS versions before fleet deployment.
  • Bash 4.x+ and standard coreutils (curl, sed, awk) required; some edge cases (BSD sed, Alpine musl) may cause parsing errors—pre-test on specific distro versions.
  • Script modifies system-wide settings (firewall, kernel tuning, package installation); ensure change management approval and backup procedures before execution on production.
  • Auto-update mechanism may pull breaking changes; version pinning or staged rollouts recommended for critical infrastructure.

When to avoid it — and what to weigh

  • Enterprise Production at Scale — Shell script-based tooling lacks the auditability, version control depth, and rollback guarantees required in high-compliance or large-scale infrastructure. Use infrastructure-as-code (Terraform, Ansible) instead.
  • Multi-Region or Kubernetes-Native Deployments — KEJILION.SH targets traditional VPS/VM models and single-host Docker. It is not designed for Kubernetes clusters, multi-cloud orchestration, or stateless container registry pipelines.
  • Need for Real-Time Observability & Alerting — The toolkit provides basic system info snapshots but no persistent metrics collection, alert routing, or time-series visualization. Integrate separately with Prometheus, Grafana, or DataDog for production observability.
  • Strict Code Review & Security Scanning Requirements — Bash scripts with 75 open issues and unverified remote-execution model (bash <(curl)) may not pass security gating for regulated industries without full source audit and sandboxed testing.

License & commercial use

Licensed under Apache License 2.0 (Apache-2.0), a permissive OSI-approved license allowing commercial use, modification, and distribution with proper attribution and liability disclaimers.

Apache 2.0 permits commercial use without royalty. However, downstream liability for system changes (firewall modifications, kernel tuning, data loss from backup failures) rests with the operator. No warranty is provided; review license disclaimers and conduct isolated testing before production deployment. Consider legal review if integrating into a SaaS or managed service offering.

Security considerations

Remote execution (curl | bash) is a known attack vector; ensure network transport is over HTTPS and source is trusted. Script handles system credentials (database passwords, SSH keys) and firewall rules—audit code for secrets hardcoding and plaintext logging. WAF/anti-CC features rely on iptables/ufw; effectiveness depends on underlying OS kernel version and DDoS scope. No published security audit, vulnerability reporting process, or CVE tracking evident; request security contact and incident response procedure before production use.

Alternatives to consider

Ansible + Community Playbooks

Provides idempotent, declarative infrastructure-as-code with version control, multi-host orchestration, and extensive third-party role library. Better for teams requiring audit trails, enterprise support, and heterogeneous stack management.

Terraform + cloud-init / Packer

Cloud-native approach enabling immutable infrastructure, multi-cloud support, and reproducible provisioning. Preferred for CI/CD pipelines, infrastructure-as-code drift detection, and managed backup/restore workflows.

cPanel / Plesk / DirectAdmin

GUI-driven commercial hosting control panels with built-in LNMP, SSL, backup, DNS, and support. Better for non-technical users and hosters requiring customer self-service portals, though less flexible for DevOps workflows.

sh FAQ

Is KEJILION.SH suitable for production web hosting?
Suitable for small-to-medium VPS deployments with proper validation and change management. Not recommended for high-compliance, large-scale, or Kubernetes-based infrastructure without supplementary tooling (monitoring, disaster recovery, secrets management).
Can I use it on CentOS 6 or older Ubuntu versions?
Documented support covers modern distros (Ubuntu 18+, CentOS 7+, Debian 9+, Alpine 3.x). Older versions may fail due to missing systemd, package availability, or bash version incompatibilities; test in isolated environment first.
Does it support Windows Server or non-Linux environments?
No. KEJILION.SH is Linux-only. For Windows Server, use native PowerShell DSC, Chocolatey, or cloud-init on supported hypervisors.
What happens if the auto-update mechanism pulls a breaking change?
Version pinning or disabling auto-update is recommended. Monitor release notes, test updates in staging, and maintain offline backups of working script versions for critical systems.
