Reset the Web UI Admin Password
This section explains how to set the web UI admin password using the Horizon installation script.
After you install Horizon, the web UI admin user’s password is set to
admin by default.
You can change this password after the initial login to the Horizon web UI.
In the case of a forgotten password or deployment scenarios that require users to set this password on installation you can use the Horizon installation script to reset this password.
You need to add the option ` -R` (or
--reset-webui-password) and provide the password to set as an argument.
Skip upgrade tasks and set web UI admin password to "foobar"
sudo /usr/share/opennms/bin/install -S -R foobar
