Step 3: Next, enable and start the cockpit.socket service to connect to the system through the web console by using the below command
[root@linuxhelp ~]# systemctl enable --now cockpit.service
The unit files have no installation config (WantedBy, RequiredBy, Also, Alias
settings in the [Install] section, and DefaultInstance for template units).
This means they are not meant to be enabled using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
.wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, ...).
4) In case of template units, the unit is meant to be enabled with some
instance name specified.
[root@linuxhelp ~]# systemctl start cockpit.service
Step 4: Verify the service and running the cockpit process using the below command
[root@linuxhelp ~]# systemctl status cockpit.socket

Step 5: If you are running a firewalld on the system, you need to open the cockpit port 9090 in the firewall by using the below command.
[root@linuxhelp ~]# firewall-cmd --add-service=cockpit --permanent
Warning: ALREADY_ENABLED: cockpit
success
[root@linuxhelp ~]# firewall-cmd --reload
success
Step 6: Open the Cockpit web console in your web browser by using the below URL’s:
Locally: https://localhost:9090
Remotely with the server’s hostname: https://example.com:9090
Remotely with the server’s IP address: https://192.168.0.10:9090
Step 7: If you are using a self-signed certificate, you will get a warning on the browser, simply verify the certificate and accept the security exception to proceed further with the login as shown in the below image.
Step 8: In the web console login screen, enter your system user name and password as shown in the below image.
