To use HA Web Konsole, the respective Web service must be started on the node that you want to connect to with the Web interface. For communication, the standard HTTP(s) protocol and port 7630 is used.
On the node you want to connect to, open a shell and log in as root.
Check the status of the service by entering
rchawk status
If the service is not running, start it with
rchawk start
If you want the HA Web Konsole to start automatically at boot time, execute the following command:
chkconfig hawk on
On any machine, start a Web browser and make sure that JavaScript and cookies are enabled.
Point it at the IP address or hostname of any cluster node, or the address of any IPaddr(2) resource that you may have configured:
https://IPaddress:7630/
NOTE: Certificate Warning
Depending on your browser and browser options, you may get a certificate warning when trying to access the URL for the first time. This is because the HA Web Konsole uses a self-signed certificate that is not considered trustworthy per default.
To proceed anyway, you can add an exception in the browser to bypass the warning. To avoid the warning in the first place, the self-signed certificate can also be replaced with a certificate signed by an official Certificate Authority. For information on how to do so, refer to Replacing the Self-Signed Certificate.
On the HA Web Konsole login screen, enter the and of the hacluster user (or of any other user that is member of the haclient group) and click .
The screen appears, displaying the status of your cluster nodes and resources similar to the output of the crm_mon.
