Managing Linux Services with systemctl Systemd is the default init system on most modern Linux distributions. The systemctl command is the primary tool for managing services. This article covers the most common operations. 1. Checking Service Status To see whether a service is running: systemctl status nginx The output shows the active state, main PID, memory usage, and recent log entries. A green active running line means the service is healthy. ...
Using systemd Timers for Scheduled Tasks On Linux systems, scheduled tasks are often associated with cron. It is simple, widely available, and still useful today. However, on modern Linux distributions that use systemd, there is another powerful option: systemd timers. A systemd timer can run a service at a specific time, after boot, or at regular intervals. Compared with traditional cron jobs, systemd timers integrate better with the system service manager, provide better logging, and offer more flexible scheduling options. ...
Static Site Deployment Checklist Static websites are simple to operate, but a few basic checks can make them more reliable and easier to maintain. This note summarizes a minimal deployment checklist for small documentation sites, project pages, and service information pages. 1. Confirm DNS Records Before deploying the site, confirm that the domain points to the correct server address. For most small websites, an A record is enough: A record for IPv4 AAAA record only if IPv6 is available CNAME record for aliases or subdomains Avoid adding unused records. Incorrect IPv6 records are a common cause of connection failures when the server does not actually support IPv6. ...
