Change the Open Distro for Elasticsearch passwords
In this section we will show you how to change the passwords of the Open Distro for Elasticsearch users to secure your installation.
We provide a script to simplify the process of changing passwords, start by downloading it:
# curl -so wazuh-opendistro-passwords-tool https://packages.wazuh.com/4.3/wazuh-opendistro-passwords-tool.sh
The script allows changing the password for either a single user or all the users present on the /usr/share/elasticsearch/plugins/opendistro_security/securityconfig/internal_users.yml file. It also offers the option to change the password of more than one user at once, getting them from a formatted file. All the available options to run the script are:
Options |
Purpose |
|---|---|
-a / --change-all |

-p / --password <password> |

-u / --user <user> |

Change the password for single user
To change the password for a single user, run the script with the -u option. You may indicate the new password with the option -p. If no password is specified, the script will generate a random one.
# bash wazuh-opendistro-passwords-tool -u admin -p mypassword
This is the output of the script:
Creating backup... Backup created Generating hash Hash generated Loading changes... Done Password changed. Remember to update the password in /etc/filebeat/filebeat.yml and /etc/kibana/kibana.yml if necessary and restart the services.
Change the passwords for all users
To generate and change the passwords for all users, run the script with the -a option:
# bash wazuh-opendistro-passwords-tool -a
This is the output of the script:
Generating random passwords Done Creating backup... Backup created Generating hashes Hashes generated Loading changes... Done The password for admin is Re6dEMVUcB_c6rEDf_C_nkBCZkwFKtZL The password for kibanaserver is 4KLxLHor69cq2i1jFXmSUjBTVjG2yhU9 The password for kibanaro is zCd-SrihVwzfRxj5qPrwlSgmZJP9RsMA The password for logstash is OmbPImuV5fv11R6XYAG92cUjaDy9PkdH The password for readall is F2vglVGFJHXohwqEW5G4Tfjsiz-qqkTU The password for snapshotrestore is rd35bCchP3Uf-0w77VCEJzHF7WEP3fNw Passwords changed. Remember to update the password in /etc/filebeat/filebeat.yml and /etc/kibana/kibana.yml if necessary and restart the services.
Change the passwords using a formatted file
To use a formatted file to indicate the passwords, run the script with the -f option followed by the file path. Use the following pattern to indicate the users and passwords in the formatted file:
User: name: wazuh password: <password_wazuh> User: name: kibanaserver password: <password_kibanaserver>
If the -a option is used in combination with the -f option, all users not included in the file are given a random password.
In distributed deployments, you will need to change or update the passwords in both /etc/filebeat/filebeat.yml and /etc/kibana/kibana.yml. After changing the configuration files, remember to restart the corresponding services.
