slickstack

SlickStack is a free Bash-based automation script that provisions and optimizes a complete WordPress hosting environment (LEMP stack) on Ubuntu. It handles Nginx, PHP-FPM, MySQL, SSL, caching, and security hardening in a single, idempotent installation with minimal operational overhead.

What slickstack is

Pure Bash provisioning tool (no external runtime dependencies) that configures Ubuntu LTS, Nginx 1.24.x, PHP-FPM 8.3.x, MySQL 8.0.x, Memcached, Certbot, and Fail2ban with optimized config files. Runs scheduled cron jobs to sync configuration with a GitHub repository and supports both self-signed OpenSSL and Let's Encrypt certificates.

Quickstart

Get the slickstack source

Clone the repository and explore it locally.

terminalbash

1git clone https://github.com/littlebizzy/slickstack.git2cd slickstack3# follow the project's README for install & configuration

Best use cases

Single-domain WordPress hosting on VPS

Ideal for agencies, freelancers, and SMBs deploying one WordPress site per server (KVM on DigitalOcean, Vultr, Linode). Eliminates manual stack setup and provides repeatable, performant baseline configuration.

Performance-focused WordPress deployments

Pre-optimized Nginx, PHP-FPM, and Memcached configurations reduce setup time and deliver known-good performance tuning without custom benchmarking or DevOps expertise.

Lightweight DevOps automation without containerization

Teams seeking server provisioning without Docker, Kubernetes, or Python dependencies; Bash-only approach reduces surface area and operational complexity on standalone VPS infrastructure.

Implementation considerations

Installation requires root SSH access to a fresh Ubuntu LTS VPS (1GB+ RAM minimum, 2GB+ recommended for dynamic sites); runs a single idempotent script (`bash ss`) that can be safely re-run.
HTTPS-only by default with self-signed certificates; Cloudflare must be active upstream for certificate validation to work in browsers, or switch to Let's Encrypt via `ss-config` before install.
Cron jobs automatically sync configuration from GitHub repository; audit network egress policies and GitHub availability before deploying in restricted environments.
Single-domain-per-server design simplifies operations but makes horizontal scaling difficult; scale vertically (upgrade RAM/CPU) and re-run `ss-install` to recalibrate.
Requires post-install familiarity with `/var/www/` management scripts (`ss-install`, `ss-clean-files`, etc.) and editing `ss-config` for Let's Encrypt, staging/dev site setup, and other tuning.

When to avoid it — and what to weigh

Multi-tenancy or multiple domains per server — SlickStack explicitly does not support multiple TLDs or multi-tenant deployments. Each server is locked to one primary domain by design.
Requiring graphical UI or dashboard — No built-in web UI for management. Configuration is CLI/SSH-based via `/var/www/` scripts. Not suitable for teams expecting visual server dashboards.
Enterprise clustering or load balancing — Designed for simple, high-performance single-server WordPress. Server clustering, failover, or advanced scaling architectures are out of scope.
Non-WordPress or non-LEMP workloads — Purpose-built for WordPress on Nginx. Running other applications (Django, Rails, Node, etc.) is not a supported use case.

Security considerations

Stack includes Fail2ban, Iptables (v1.8.x rules), and HSTS enforcement. Self-signed OpenSSL certificates are default; upgrade required for production (Let's Encrypt or custom CA). Cron jobs pull config from GitHub; ensure repo integrity and network security. PHP-FPM, MySQL, and Nginx are hardened via optimized configs, but no formal security audit, CVE tracking, or penetration test results are documented. Adminer is bundled; ensure adequate IP whitelisting or authentication if exposed.

Alternatives to consider

EasyEngine

Python-based LEMP stack provisioning with more advanced features (multi-site support, Let's Encrypt by default, CLI-driven management). Higher overhead; requires Python runtime.

Ansible + Galaxy roles

Declarative provisioning and configuration management with broad ecosystem. More complex learning curve; requires Ansible controller and SSH key management; flexible for multi-server environments.

WordPress.com Jetpack or Managed WordPress hosting (Kinsta, WP Engine)

Fully managed hosting removes all provisioning and stack management burden. Higher cost; vendor lock-in; no direct server control.

Software development agency

Build on slickstack with DEV.co software developers

If your team operates standalone WordPress VPS infrastructure without multi-tenancy or UI requirements, SlickStack can reduce provisioning overhead. Review the cron-based GitHub sync model, SSL configuration, and single-domain constraint before adoption. Devco can advise on integration with your DevOps pipeline.

slickstack FAQ

Can I run multiple WordPress sites (domains) on a single SlickStack server?

No. SlickStack explicitly supports only one primary domain per server. This is a design constraint to keep the stack simple, fast, and stable.

What if my environment does not have internet access to GitHub?

SlickStack relies on cron jobs syncing config from GitHub. Air-gapped deployments would require manual mirroring or disabling cron sync; this is not documented as a supported scenario.

Do I need Cloudflare to use SlickStack?

No, but Cloudflare is recommended for production HTTPS with self-signed certificates (SlickStack default). You can switch to Let's Encrypt instead by editing `ss-config` before running the installation.

How do I upgrade server hardware (more RAM/CPU)?

Upgrade your VPS, then re-run `sudo bash /var/www/ss-install`. The installation process is idempotent and will recalibrate optimizations for the new hardware without data loss.
