4. Open the Cockpit web console in your web browser at the following 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
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.
The console calls a certificate from the
/etc/cockpit/ws-certs.d directory and uses the
.cert extension file. To avoid having to prompt security warnings, install a certificate signed by a certificate authority (CA).
5. In the web console login screen, enter your system user name and password.
If a user account has sudo privileges, this makes it possible to perform administrative tasks such as installing software, configuring system or configuring SELinux in the web console.
