To troubleshoot the 500 error in VestaCP with the SK template and resolve the "Connection reset by peer" and "End of script output before headers" errors, please follow these detailed steps:
1. Check PHP-FPM Configuration:
Log in to your server via SSH.
Navigate to the PHP-FPM pool configuration directory. The path may vary depending on your operating system and PHP version. For example, it could be /etc/php-fpm.d/ or /etc/php/7.4/fpm/pool.d/.
Look for the configuration file associated with the domain or script causing the error (e.g., mydomain.com.conf).
Open the configuration file using a text editor.
Verify and adjust the following directives as necessary:
listen: Ensure it is set to the correct address and port, usually 127.0.0.1:9000.
listen.owner and listen.group: Confirm that the user and group ownership match those used by your web server (e.g., apache, www-data).
user and group: Ensure the correct user and group are specified.
Save the changes to the configuration file.
2. Restart PHP-FPM and Apache:
After modifying the PHP-FPM configuration, you need to restart both PHP-FPM and Apache for the changes to take effect.
Execute the following commands to restart PHP-FPM and Apache:
Code: Select all
sudo service php-fpm restart
sudo service apache2 restart
Note: The commands may vary depending on your operating system. For example, on CentOS, you can use sudo systemctl restart php-fpm and sudo systemctl restart httpd.
3. Verify the SK Template Configuration:
Log in to your VestaCP control panel.
Go to the "Web" section and click on the affected domain.
Under the "Web Template" section, make sure the correct PHP version and SK template are selected.
If you have made changes to the template, click on the "Rebuild Web" button to apply the changes.
Save the changes if any modifications were made.
4. Check Error Logs:
Examine the error logs for the domain to gather additional information about the issue. The error logs are usually located in the following directory: /home/<username>/log/<domain>/error.log.
Look for any new error messages that may help identify the root cause of the problem.
5. Verify Apache Configuration with SK Template:
If Apache fails to start after replacing IncludeOptional with Include in the Apache configuration, it might be due to incorrect configuration in the SK template.
To fix this, navigate to the directory where your SK template files are located. It is typically located in /usr/local/vesta/data/templates/web/sk.
Open the template file named web.conf or web.stpl using a text editor.
Search for the line that includes IncludeOptional and replace it with Include.
Save the changes to the template file.
6. Rebuild Web Configuration:
Log in to your VestaCP control panel.
Go to the "Web" section and click on the affected domain.
Under the "Web Template" section, click on the "Rebuild Web" button.
This will regenerate the Apache configuration files based on the modified SK template.
7. Restart Apache:
After rebuilding the web configuration, restart Apache using the following command:
By following these steps, you should be able to resolve the 500 error and the "Connection reset by peer" and "End of script output before headers" errors in VestaCP with the SK template. If the issue persists or you encounter any new error messages, please provide the relevant details, including the error logs, for further assistance.
