This article describes how to manage users and passwords for your NiFi instance.
You can change the NiFi login password for any user from the command-line of the instance operating system.
First, Connect to your instance using Secure Shell (SSH). The command will look like the following example, but you must substitute your actual EC2 key pair file and instance public DNS above:
ssh -i ~/.ssh/YourEC2KeyPair.pem email@example.com
At the prompt, run the BatchIQ set password utility to set a new password. The format is as follows:
sudo batchiq-admin set-password <user> <new password>
For example, to change the admin user's password to "newpassword", it would appear as follows:
sudo batchiq-admin set-password admin newpassword
BatchIQ instances include a username/password authentication scheme for users. Configuration files must be edited to add new users and authorize their actions.
vitools for editing via the Linux shell. Nano is recommended if you are unfamiliar with these tools. Backing up these files before editing is always recommended.
An authentication or password entry for each user is
required in the
credentials.xml file for your instance, stored by default at
You should edit this file to contain one XML
<users> entry for each user like the following:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?> <credentials> <user name="admin" passwordHash="$2a$10$..." /> <user name="james" passwordHash="$2a$10$..." /> <user name="sally" passwordHash="$2a$10$..." /> ... </credentials>
sudo nano /var/nifi/home/security/credentials.xml
Do not worry about the
passwordHash field while adding a user.
After you create an entry for the new user in the file, update the password as described in Changing Passwords above.
NiFi assigns roles to users that control what they can see and do in the NiFi user interface.
Roles are configured in the
authorized-users.xml file, located by default at
<users> <user dn="admin"> <role name="ROLE_ADMIN"/> <role name="ROLE_DFM"/> <role name="ROLE_PROVENANCE"/> </user> <user dn="james"> <role name="ROLE_DFM"/> <role name="ROLE_PROVENANCE"/> </user> <user dn="sally"> <role name="ROLE_DFM"/> </user> ... </users>
To edit this file with Nano:
sudo nano /var/nifi/home/conf/authorized-users.xml
You will need to restart NiFi to apply new or removed users. Restart by running the command:
sudo service nifi restart
