Step 4 : Next enable the cockpit service by using the below command
[root@linuxhelp ~]# systemctl enable cockpit
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.
Step 5 : Start the service by running the below command
[root@linuxhelp ~]# systemctl start cockpit
Step 6 : Next check the status of the cockpit by using the below command
[root@linuxhelp ~]# systemctl status cockpit

Step 7 : Then add the zone and reload that in the firewall by using the below command
[root@linuxhelp ~]# firewall-cmd --permanent --zone=public --add-service=cockpit
success
[root@linuxhelp ~]# firewall-cmd --reload
success
Step 8: Open the Cockpit web console in your web browser by using the below URL’s:
Locally: https://localhost:9090
Step 9: 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 10: Enter into the web console login screen and type your system user name and password as shown in the below image.
Step 11: After successful authentication, the Cockpit web console interface page open. Here we can view the running of page Cockpit web console interface as shown in the below image
Conclusion:
We have reached the end of this article. In this guide, we have walked you through the steps required to Install Cockpit web console on Rocky linux 8.6. Your feedback is much welcome.
