How to restart the cPanel service using SSH

This guide needs root access. Root is the all-powerful admin user on a server. VPS and dedicated server owners have it.

What does this do?

cPanel is the control panel for managing websites and email. It runs as a service, which is a program that works in the background. Sometimes the panel gets stuck and the login page will not open. Restarting the service often fixes this. SSH is a safe way to type commands on a faraway server.

Restarting cPanel does not turn off your websites. It only affects the panel pages for a short time.

Steps

Open an SSH program. On Windows you can use PuTTY. On Mac or Linux use the Terminal app.
Connect to your server with its IP address and root details:
```
ssh root@your-server-ip
```
Your welcome email holds the IP address. If you cannot find it, ask support.
Type the password when asked. Nothing shows on the screen while you type. This is normal.
Restart cPanel with this command:
```
/scripts/restartsrv_cpsrvd
```
It restarts the program that serves the cPanel and WHM pages.
Check that it is running:
```
/scripts/restartsrv_cpsrvd --status
```
Open WHM or cPanel in your browser. Use the ports 2087 for WHM and 2083 for cPanel.

Other helpful commands

Command	What it does
`/scripts/restartsrv_httpd`	Restarts Apache, the web server
`/scripts/restartsrv_mysql`	Restarts the database service
`/scripts/restartsrv_exim`	Restarts the mail sending service
`/scripts/restartsrv_named`	Restarts the DNS service

Tip: If the panel still does not load, check that the disk is not full with df -h. A full disk is a common cause.
