     Active: active (running) since Mon 2022-09-19 23:31:07 IST; 19s ago
    Process: 38301 ExecStart=/usr/bin/python3 /usr/local/bin/ajenti-panel -d (code=exited, status=0/SUCCESS)

Step 5: Configure Firewall by using the below command

[root@linuxhelp ~]#  firewall-cmd --permanent --zone=public --add-port=8000/tcp
[root@linuxhelp ~]#  firewall-cmd --reload

Step 6: Open Ajenti Web Interface as shown in the below image Once port is allowed, you are now ready to access the Ajenti Web URL from your favorite web browser. You need to use URL address https://<your_ip_address>:8000 in your browser to open the Login page as shown like below.

Step 7: Here you need to provide your System account credentials to login. Once provided, click on Log In as shown in the below image.

Step 8: After successful authentication, you will be redirected to below Dashboard. Here you can see your default Server utilization metrics. This includes CPU Usage, Active Cores, Total Memory, current memory usage, uptime etc as shown in the below image

Step 9: Similarly you can also check the list of installed plugins by going to General->Plugins page. Here you can see all the currently installed plugins as shown in the below image

Step 10: In case if you want to add a widget then you can do that by clicking on Add widget on the Dashboard Page. Here you can see list of widget that can be added to the Dashboard. For the demonstration purpose, I am going to choose Disk space widget as shown in the below images

Step 11: Stop, Disable and check status of Ajenti and Uninstall Ajenti by using the below commands

[root@linuxhelp ~]#  systemctl stop ajenti
[root@linuxhelp ~]#   systemctl status ajenti
● ajenti.service - Ajenti panel
Loaded: loaded (/usr/lib/systemd/system/ajenti.service; enabled; vendor preset: disabled)

[root@linuxhelp ~]#  systemctl disable ajenti
Removed /etc/systemd/system/multi-user.target.wants/ajenti.service.
[root@linuxhelp ~]#  systemctl daemon-reload

[root@linuxhelp ~]#  pip uninstall ajenti-panel ajenti.plugin.dashboard ajenti.plugin.settings ajenti.plugin.plugins ajenti.plugin.notepad ajenti.plugin.terminal ajenti.plugin.filemanager ajenti.plugin.packages ajenti.plugin.services -y
