“One-liner” To Change Plesk Admin Port

January 31, 2025

Here’s a Bash one-liner to change the Plesk admin port:

sudo sed -i 's/listen 8443 ssl;/listen XXXX ssl;/' /etc/sw-cp-server/conf.d/plesk.conf && \
  sudo systemctl restart sw-cp-server

sudo sed -i 's/listen 8443 ssl;/listen XXXX ssl;/' /etc/sw-cp-server/conf.d/plesk.conf && \

sudo systemctl restart sw-cp-server

Replace XXXX with the desired port number. Explanation sed -i ‘s/listen 8443 ssl;/listen 8444 ssl;/’ /etc/sw-cp-server/conf.d/plesk.conf Searches for listen 8443 ssl; in the configuration file and replaces it with listen 8444 ssl;. sudo systemctl restart sw-cp-server Restarts the Plesk control panel server to apply the new port configuration.

1 2	for file in /var/www/vhosts/*/logs/access_ssl_log; do \ echo "$file: $(grep -c 'DD/MMM/YYYY:HH:MM' "$file")"; done \| sort -t: -k2 -nr
