Ports used by CentOS Web Panel

The main ports to access the CentOS Web Panel are 2030 and 2031.  Lately, CentOS Web Panel also uses ports 2086/2087 and 2082/2083 (similar to WHM). To summarize:

These ports are configured in the file /usr/local/cwpsrv/conf/cwpsrv.conf . You can check this file via command line with a utility like nano, or via the CentOS Web Panel File Manager. The contents of the cwpsrv.conf file is:

worker_processes  2;

    worker_connections  2048;

    include /usr/local/cwpsrv/conf.d/*.conf;
}

To redirect the non-secure ports to secure ports add the following lines to the file /usr/local/apache/htdocs/.htaccess

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

CentOS Web Panel uses the standard ports for services like the email server, SSH etc. :
