Because SlickStack is built on top of Ubuntu LTS, the basic system requirements are generally the same. However, because several different modules are installed, and after several years of testing, we recommend installing SlickStack on cloud servers as explained below:
Last updated: Jul 10, 2021
- Choose a quality datacenter located near your audience (if your SlickStack-powered website is for a local business in Miami, Florida, then selecting a datacenter in Atlanta, Georgia, would be better than Seattle, Washington).
- Setup a dedicated Virtual Machine (or a traditional dedicated server/bare-metal server) that provides root/console access.
- KVM virtualization is highly recommended for VM (VPS) instances instead of e.g. OpenVZ, Xen, etc.
- Ubuntu LTS is required… use other distros at your own risk.
- Allocate at least 2GB+ RAM memory (1GB RAM should work for small sites, but 2GB+ RAM is recommended for more dynamic sites… for example, WooCommerce sites). SlickStack also creates a 2GB swapfile by default, which we recommend keeping enabled.
- At least 1 CPU core is recommended (but 2+ CPU cores is much more responsive).
- Do not install “containers” e.g. Docker, Kubernetes, etc.
In addition, we recommend following these tips:
- Register your domain at a top-level ICANN-accredited registrar (no resellers).
- Enable DNSSEC in CloudFlare (and at your registrar).
- Use only the CloudFlare.com dashboard for all DNS records/pointing (don’t use your domain registrar or web hosting/cloud network for any DNS records, even if they tell you that their system “integrates” CloudFlare’s technology or CDN, etc).
- Setup A records for IPv4 and AAAA records for IPv6 (avoid CNAMES for the origin server, which can be slower).
- Optimize all your CloudFlare settings (review this blog post).
