I have a NagiosXI server which i already 2 year never login. Recently one of the System Admin leaving the company and i have to take over back the NagiosXI server management. But i already forgot what is nagiosadmin password.

Lucky NagiosXI come with a lot of useful scripts which located at /usr/local/nagiosxi/scripts/

Here i going to show your guys how i reset the nagiosadmin password using NagiosXI script.

To do that, you have to ssh in to NagiosXI server and execute following command to reset nagiosadmin password

/usr/local/nagiosxi/scripts/reset_nagiosadmin_password.php --password=newpassword

If you wish to use any special  characters in your password, you should escape them with “\”. For example, if you want to set your new password to be “p@ssw0rd#”, then you can run:

/usr/local/nagiosxi/scripts/reset_nagiosadmin_password.php --password=p\@ssw0rd\#

After reset, you should able to login to your NagiosXI with your new password.
