Running MySQL or MariaDB on a 1-2 GB VPS is entirely practical, but the default configuration is written for a machine with far more RAM than you have. Left alone,…

Transparent Huge Pages (THP) were designed to make Linux’s large-page optimizations automatic: the kernel’s khugepaged thread scans memory and promotes eligible 4 KB pages into 2 MB (or 1 GB)…

A dropped SSH connection should never kill a database migration, a long rsync, or a kernel build. Tmux keeps your shells alive on the server independently of the network, and…

Step-by-step guide to capping journald with size and time limits, writing a working logrotate policy, confirming the timer runs, and verifying with a log flood test.

Database replication is often associated with multi-server architectures, but you can run a fully functional MySQL master-slave setup on a single VPS. Why would you do that? For backups without…

Network latency and throughput are critical for web applications, APIs, and real-time services. While many users focus on application-level optimizations, the Linux kernel’s network stack offers a rich set of…

A reverse proxy is the single highest-leverage piece of software on a small VPS. It terminates TLS, absorbs slow clients, and keeps a pool of persistent connections open to your…

Every VPS operator has backups. Very few have ever restored one under pressure. The gap between a backup and a recovery capability is measured in two numbers that most teams…

A single VPS is a single point of failure. Hardware failures, host crashes, and network outages all take your application offline. Keepalived uses the Virtual Router Redundancy Protocol (VRRP) to…

A CI/CD pipeline automates testing, building, and deploying your application — but many developers assume you need a paid CI service or a second server to run one. In reality,…
