WARNING: Version 6.1 of Elasticsearch has passed its EOL date.
This documentation is no longer being maintained and may be removed. If you are running this version, we strongly advise you to upgrade. For the latest information, see the current release documentation.
If you use file-based user authentication, the users
command enables you to
add and remove users, assign user roles, and manage passwords.
bin/x-pack/users ([useradd <username>] [-p <password>] [-r <roles>]) | ([list] <username>) | ([passwd <username>] [-p <password>]) | ([roles <username>] [-a <roles>] [-r <roles>]) | ([userdel <username>])
If you use the built-in file
internal realm, users are defined in local files
on each node in the cluster.
Usernames and roles must be at least 1 and no more than 1024 characters. They
can contain alphanumeric characters (a-z
, A-Z
, 0-9
), spaces, punctuation,
and printable symbols in the
Basic Latin (ASCII) block.
Leading or trailing whitespace is not allowed.
Passwords must be at least 6 characters long.
For more information, see File-based User Authentication.
To ensure that Elasticsearch can read the user and role information at startup, run
users useradd
as the same user you use to run Elasticsearch. Running the command as
root or some other user updates the permissions for the users
and users_roles
files and prevents Elasticsearch from accessing them.
-
-a <roles>
-
If used with the
roles
parameter, adds a comma-separated list of roles to a user.
-
list
-
List the users that are registered with the
file
realm on the local node. If you also specify a user name, the command provides information for that user. -
-p <password>
-
Specifies the user’s password. If you do not specify this parameter, the command prompts you for the password.
Omit the
-p
option to keep plaintext passwords out of the terminal session’s command history. -
passwd <username>
-
Resets a user’s password. You can specify the new
password directly with the
-p
parameter. -
-r <roles>
-
-
If used with the
useradd
parameter, defines a user’s roles. This option accepts a comma-separated list of role names to assign to the user. -
If used with the
roles
parameter, removes a comma-separated list of roles from a user.
-
If used with the
-
roles
- Manages the roles of a particular user. You can combine adding and removing roles within the same command to change a user’s roles.
-
useradd <username>
- Adds a user to your local node.
-
userdel <username>
- Deletes a user from your local node.
The following example adds a new user named jacknich
to the file
realm. The
password for this user is theshining
, and this user is associated with the
network
and monitoring
roles.
bin/x-pack/users useradd jacknich -p theshining -r network,monitoring
The following example lists the users that are registered with the file
realm
on the local node:
bin/x-pack/users list rdeniro : admin alpacino : power_user jacknich : monitoring,network
Users are in the left-hand column and their corresponding roles are listed in the right-hand column.
The following example resets the jacknich
user’s password:
bin/x-pack/users passwd jachnich
Since the -p
parameter was omitted, the command prompts you to enter and
confirm a password in interactive mode.
The following example removes the network
and monitoring
roles from the
jacknich
user and adds the user
role:
bin/x-pack/users roles jacknich -r network,monitoring -a user
The following example deletes the jacknich
user:
bin/x-pack/users userdel jacknich
