Configure Firewall

With the Ajenti service started, we need to open port 8000 on the firewall. With the port enabled through the firewall, we will be able to access and login into the Ajenti web interface. To allow the port through the firewall on CentOS 8|RHEL 8|Rocky Linux 8 use:

sudo firewall-cmd --permanent --zone=public --add-port=8000/tcp
sudo firewall-cmd --reload

3) Access and Use Ajenti Control Panel

Ajenti works on port 8000 with secure HTTP(HTTPS). Now we access the Web Interface using the server IP http://ip:8000 or domain-name http://domainname.com:8000.
