cpsrvd Complete Guide - cPanel Service Daemon Troubleshooting

The term cpsrvd refers to cPanel Service Daemon, which is a core component of cPanel & WHM (Web Host Manager). This service handles HTTP and HTTPS requests for the cPanel and WHM interfaces, including webmail and APIs.

Key Points About cpsrvd:

Essential service for cPanel/WHM functionality
Manages web-based control panel access
Runs on ports 2082, 2083, 2086, 2087, 2095, and 2096
Separate from Apache/NGINX web servers

What is cpsrvd?

cpsrvd acts as a lightweight web server specifically designed for managing the cPanel interfaces and services.
It is not a general-purpose web server like Apache or NGINX; instead, it is built to serve requests for cPanel, WHM, and webmail functionality.

cpsrvd typically runs on ports 2082 (HTTP), 2083 (HTTPS) for cPanel, and ports 2086 (HTTP), 2087 (HTTPS) for WHM. Webmail uses ports 2095 and 2096.

Common Tasks Involving cpsrvd

Restart cpsrvd

Sometimes, if cPanel or WHM is not responding, restarting cpsrvd can help.

Command to Restart cpsrvd:

/scripts/restartsrv_cpsrvd

This command is safe to run and only restarts the cpsrvd service without affecting other cPanel services.

Check the Status of cpsrvd

To verify if cpsrvd is running properly:

systemctl status cpsrvd

You should see an output indicating that the service is active (running).

Logs for Debugging

If there are issues with cpsrvd, check its logs for more details:

tail -f /usr/local/cpanel/logs/error_log

Update cPanel to Fix cpsrvd Issues

If cpsrvd is not starting or behaving unexpectedly, updating cPanel might resolve the issue:

/usr/local/cpanel/scripts/upcp --force

This forces a cPanel update and ensures all components, including cpsrvd, are up-to-date.

Common Errors Related to cpsrvd
