Two decisions determine how a MariaDB install turns out on a fresh Ubuntu VPS: which repository the packages come from, and whether the post-install hardening script actually gets run. Skip either one and you end up with a database that's either years out of date or wide open by default. This guide covers both paths — …

Command-line clients like psql and the MySQL shell handle a quick query fine, but they start to strain once a Linux VPS admin is juggling more than one database engine, or wants to browse table structures and query history without re-learning another tool's dialect for every server. SQL Workbench/J exists for exactly …

A caching layer is one of those pieces of a VPS stack that people install once and stop thinking about — until the license under which it ships changes and suddenly matters again. That's exactly what happened with Redis, and it's why anyone provisioning a new Linux VPS for a session store, a queue backend, or a query …

A VPS with no monitoring installed only tells you about a problem after it has already become one — the process that has been leaking memory for six hours, the disk that filled up overnight, the CPU spike from a runaway cron job three days ago. Netdata closes that gap by collecting and charting server metrics every …

A stock Ubuntu install ships an ancient Docker package under a different name entirely — docker.io — if it ships one at all, and that package trails months or years behind what Docker actually maintains. The reliable path on a VPS is Docker's own apt repository, which tracks Docker Engine releases directly and gets you …

Running a VPN on a Linux server is a different problem than running one on a laptop. You need a proper CLI client that works headless, a protocol that holds up under long uptime, a kill switch that actually blocks traffic when the tunnel drops, and ideally some way to build a private network between multiple servers …

NordVPN is one of the few mainstream VPN providers that has put real engineering effort into its Linux client. The CLI is full-featured, the NordLynx protocol (WireGuard-based) runs efficiently on server hardware, and the Meshnet private networking feature addresses a use case that most VPN providers don't touch.
