Question

How to perform Plesk redirect from http://plesk.example.com:8880 to https://plesk.example.com:8443?

Answer

Warning: Port 8880 is required by Web Presence Builder and for integration with Virtuozzo containers offline management services. Do not modify it in case of the integration with 3rd-party software.

1. Connect to the server via SSH.

2. Make a backup of /etc/sw-cp-server/conf.d/plesk.conf:

   # cp /etc/sw-cp-server/conf.d/plesk.conf /etc/sw-cp-server/conf.d/plesk.conf_backup

3. Modify the content of /etc/sw-cp-server/conf.d/plesk.conf so it looks like below:

   server{
   listen 8880;
   
   listen 127.0.0.1:8880 default_server;
   
   return 301 https://$host:8443$request_uri;
   }
   
   server {
   listen 8443 ssl;
   include conf.d/*ipv6_ports.inc;
   
   
   ssl_certificate /opt/psa/admin/conf/httpsd.pem;
   ssl_certificate_key /opt/psa/admin/conf/httpsd.pem;
   
   include conf.d/*plesk.inc;
   include conf.d/*wpb.inc;
   }

4. Restart sw-cp-server service:

   # service sw-cp-server restart
