CloudPanel v1 is obsolete

CloudPanel v1 is obsolete; check out the CloudPanel v2 Docs.


Adding a Domain

A new domain can be added by clicking on button Add Domain top right.

In this form you enter the Domain Name, the Document Root and you select a Vhost Template
and PHP Version for your application.


Make sure to read about PHP-FPM Pools before adding a domain.

When you click on the button Add Domain, the following things will be created by CloudPanel:

  • The Document Root: /home/cloudpanel/htdocs/
  • Vhost file for NGINX: /etc/nginx/sites-enabled/
  • NGINX Access and Error Log file:
    • /home/cloudpanel/logs/
    • /home/cloudpanel/logs/
  • PHP-FPM Error Log file:
    • /home/cloudpanel/logs/
  • A self-signed TLS certificate

When you enter your Domain Name with www a redirection from non-www to www will be created automatically and vice versa. Furthermore http requests are redirected to https.

Deleting a Domain

When you delete a domain, only the vhost and the NGINX and PHP log directories will be deleted,
NOT the Document Root Directory.


In the settings of your domain, you can change the Document Root for your domain.


In the Vhost Editor you can make changes on the NGINX vhost.

In our example, we have entered the domain

In lines 1-10, you see a redirection from http(s):// to

The next server block is handling all http and https requests for the domain

In the lines 33-35, you see the redirection rule to redirect all http requests to https.

Domain Aliases

Aliases of your domain can be added in the vhost by extending the server_name value.

SSL/TLS Certificate

When you issue a SSL/TLS certificate make sure to include the domain aliases as well.


PHP-FPM (FastCGI Process Manager) is a FastCGI handler for PHP applications.
The web server NGINX is forwarding all PHP requests to PHP-FPM via FastCGI.

Each PHP Version is organized in PHP-FPM Pools, the configured Pools can be found in the following directory:


Each PHP Version has a default PHP-FPM Pool:


The content of the default PHP-FPM Pool looks like the following one:

listen =
user = clp
group = clp
listen.allowed_clients =
pm = ondemand
pm.max_children = 250
pm.process_idle_timeout = 10s
pm.max_requests = 100
listen.backlog = 65535
pm.status_path = /status
request_terminate_timeout = 7200s
rlimit_files = 131072
rlimit_core = unlimited
catch_workers_output = yes

In the configuration above you see that the user and group is clp.

Creating a PHP-FPM Pool

Basically all PHP Applications are reading and writing files to the file system.
If you use the default PHP-FPM Pool, all created files will be created as user and group clp.

To avoid permission problems you can create additional PHP-FPM Pools.

To create a PHP-FPM Pool do the following:

1) Create a SSH User like john-ssh.

2) Go to the PHP-FPM directory and make a copy of the default PHP-FPM Pool.

cd /etc/php/$PHP_VERSION/fpm/pool.d/
cp default.conf domain.conf

3) Open the file domain.conf and change the following settings:

  • The name of the PHP-FPM Pool in the square brackets
  • listen: Increase the listener (port) number by one (e.g. port differs in example regarding your php version)
  • user: Your created SSH User (e.g. john-ssh)

In our example the new PHP-FPM Pool should look like the following one:

listen =
user = john-ssh
group = clp
listen.allowed_clients =
pm = ondemand
pm.max_children = 250
pm.process_idle_timeout = 10s
pm.max_requests = 100
listen.backlog = 65535
pm.status_path = /status
request_terminate_timeout = 7200s
rlimit_files = 131072
rlimit_core = unlimited
catch_workers_output = yes

4) Restart PHP-FPM with the following command to apply the changes:

systemctl restart php7.4-fpm

If you have created a PHP-FPM Pool for PHP 7.3, restart PHP-FPM for PHP 7.3 with the following command:

systemctl restart php7.3-fpm

Selecting a PHP-FPM Pool

When you add a new Domain, you can now select the new created PHP-FPM Pool in the PHP-Version drop down.

The PHP-FPM Pool for existing domains can be changed in the PHP Settings of your domain.

PHP Settings

In the PHP Settings of your domain, you can change the PHP Version and make other settings like:

  • memory_limit
  • max_execution_time
  • max_input_time
  • post_max_size
  • upload_max_filesize

The most common settings can be modified to your needs but if you need to change other parameter values you can overwrite them in the Additional configuration directives.


Keep the memory_limit and max_execution values as low as possible to keep the server stable.
In the PHP Error Log, you find all error messages of processes that run out of memory or exceeded the max_execution_time.

Basic Auth

In the Basic Auth settings of your domain, you can enable and disable Basic Auth.
Users can be added, and IPs to bypass Basic Auth can be whitelisted.

A Basic Auth is useful to prevent traffic to your site when you don't want to have it public, e.g. during the development of a project or for test/staging environments.


In the Log Viewer you can check the NGINX Access and Error Logs and the PHP Error Log.

Developers who prefer the command line can find the logs in the following directories:


  • Access Log: /home/cloudpanel/logs/
  • Error Logs: /home/cloudpanel/logs/


  • Error Log: /home/cloudpanel/logs/

To see the last 100 lines of your PHP Error Log, you can use the tail command with the follow option.

tail -f /home/cloudpanel/logs/ -n100

SSL Certificates

When you add a domain, a self-signed certificate will be automatically created.

On this page, you can import an existing SSL/TLS certificate or issue a free auto-renewing Let's Encrypt certificate.

Let's Encrypt

To issue a free Let's Encrypt certificate click on button Actions and select New Let's Encrypt Certificate.

The Domain Names are pre filled. Add extra Domain Names if you have added Domain Aliases.

To issue the certificate, click on the button Create and Install and wait some seconds until it's installed.

Import SSL Certificate

The majority of the websites are fine with the free Let's Encrypt Certificates but in some cases e.g.
for an Extended Validation Certificate you need to buy and import the certificate.

To import a certificate, click on button Actions and select Import SSL Certificate.

Enter the Certificate Private Key, Certificate and the Certificate Chain and click on the button
Import and Install.
