How to Check Server Logs for Errors
VPS Servers · Self-help guide
Logs help explain why a service is failing or why a website is showing errors. Connect to your VPS using SSH. For system messages, run sudo journalctl -xe to view recent important entries. To check a specific service, use sudo journalctl -u nginx --since "1 hour ago", replacing nginx with the service name. For Apache on Ubuntu, logs are often in /var/log/apache2/. For Apache on AlmaLinux, logs are often in /var/log/httpd/. Use sudo tail -n 100 /path/to/logfile to view the last lines. Do not paste full logs publicly because they may contain paths, IP addresses, or sensitive information.
