Hi All,
After some hit and try on my local machine I was about to deploy Search Guard on test VM.
The non-prod elasticsearch node that is running have some modified elasticsearch.yml and kibana.yml.
I was going through the documentation to install on linux machine and came across
Execute ./install_demo_configuration.sh
.
And it states below:-
Note that the script only works with vanilla Elasticsearch installations. If you already made changes to elasticsearch.yml
, especially the cluster name and the host entries, you might need to adapt the generated configuration.
I naturally assumed some changes are required in sg_config since its the default config of SG but I am not sure what all changes are required or if its to be changed in this file. I am mentioning below the parameters of elasticsearch.yml and kibana.yml that are modified by previous guy. Please help me with the changes that are to be made in SG accordingly.
My elasticsearch.yml
# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
# Before you set out to tweak and tune the configuration, make sure you
# understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: my-data
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-2
#
# Add custom attributes to the node:
#
node.attr.rack: r2
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /path/to/data
#
# Path to log files:
#
#path.logs: /path/to/logs
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 10.123.211.98
#
# Set a custom port for HTTP:
#
http.port: 9202
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
#discovery.zen.ping.unicast.hosts: ["host1", "host2"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes:
#
# For more information, consult the zen discovery module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
In the above the field that are modified are:-
cluster.name
node.name
node.attr.rack
network.host
http.port
Similarly there are some changes in kibana.yml:
# Kibana is served by a back end server. This setting specifies the port to use.
server.port: 5603
# Specifies the address to which the Kibana server will bind. IP addresses and host names are both valid values.
# The default is 'localhost', which usually means remote machines will not be able to connect.
# To allow connections from remote users, set this parameter to a non-loopback address.
server.host: "10.123.211.98"
# Enables you to specify a path to mount Kibana at if you are running behind a proxy. This only affects
# the URLs generated by Kibana, your proxy is expected to remove the basePath value before forwarding requests
# to Kibana. This setting cannot end in a slash.
server.basePath: ""
# The maximum payload size in bytes for incoming server requests.
server.maxPayloadBytes: 1048576
# The Kibana server's name. This is used for display purposes.
server.name: "myserver"
# The URL of the Elasticsearch instance to use for all your queries.
elasticsearch.url: "http://10.123.211.98:9202"
# When this setting's value is true Kibana uses the hostname specified in the server.host
# setting. When the value of this setting is false, Kibana uses the hostname of the host
# that connects to this Kibana instance.
#elasticsearch.preserveHost: true
# Kibana uses an index in Elasticsearch to store saved searches, visualizations and
# dashboards. Kibana creates a new index if the index doesn't already exist.
kibana.index: ".kibana"
# The default application to load.
kibana.defaultAppId: "house"
# If your Elasticsearch is protected with basic authentication, these settings provide
# the username and password that the Kibana server uses to perform maintenance on the Kibana
# index at startup. Your Kibana users still need to authenticate with Elasticsearch, which
# is proxied through the Kibana server.
#elasticsearch.username: "user"
#elasticsearch.password: "pass"
# Enables SSL and paths to the PEM-format SSL certificate and SSL key files, respectively.
# These settings enable SSL for outgoing requests from the Kibana server to the browser.
#server.ssl.enabled: false
#server.ssl.certificate: /path/to/your/server.crt
#server.ssl.key: /path/to/your/server.key
# Optional settings that provide the paths to the PEM-format SSL certificate and key files.
# These files validate that your Elasticsearch backend uses the same key files.
#elasticsearch.ssl.certificate: /path/to/your/client.crt
#elasticsearch.ssl.key: /path/to/your/client.key
# Optional setting that enables you to specify a path to the PEM file for the certificate
# authority for your Elasticsearch instance.
#elasticsearch.ssl.certificateAuthorities: [ "/path/to/your/CA.pem" ]
# To disregard the validity of SSL certificates, change this setting's value to 'none'.
elasticsearch.ssl.verificationMode: full
# Time in milliseconds to wait for Elasticsearch to respond to pings. Defaults to the value of
# the elasticsearch.requestTimeout setting.
elasticsearch.pingTimeout: 1500
# Time in milliseconds to wait for responses from the back end or Elasticsearch. This value
# must be a positive integer.
elasticsearch.requestTimeout: 30000
# List of Kibana client-side headers to send to Elasticsearch. To send *no* client-side
# headers, set this value to [] (an empty list).
elasticsearch.requestHeadersWhitelist: [ authorization ]
# Header names and values that are sent to Elasticsearch. Any custom headers cannot be overwritten
# by client-side headers, regardless of the elasticsearch.requestHeadersWhitelist configuration.
elasticsearch.customHeaders: {}
# Time in milliseconds for Elasticsearch to wait for responses from shards. Set to 0 to disable.
elasticsearch.shardTimeout: 0
# Time in milliseconds to wait for Elasticsearch at Kibana startup before retrying.
elasticsearch.startupTimeout: 5000
# Specifies the path where Kibana creates the process ID file.
pid.file: /apps/support/dump/tomcat/ELK_dummy_Search_Guard/kibana-6.2.4-linux-x86_64/kibana.pid
# Enables you specify a file where Kibana stores log output.
logging.dest: stdout
# Set the value of this setting to true to suppress all logging output.
logging.silent: false
# Set the value of this setting to true to suppress all logging output other than error messages.
logging.quiet: false
# Set the value of this setting to true to log all events, including system usage information
# and all requests.
logging.verbose: false
# Set the interval in milliseconds to sample system and process performance
# metrics. Minimum is 100ms. Defaults to 5000.
ops.interval: 5000
# The default locale. This locale can be used in certain circumstances to substitute any missing
# translations.
i18n.defaultLocale: "en"
Field changed from default conf in Kibana are:-
server.port: 5203
server.host: “10.23.213.99”
server.basePath: “”
server.maxPayloadBytes: 1048576
server.name: “myserver”
elasticsearch.url: “http://10.123.211.98:9202”
kibana.index: “.kibana”
kibana.defaultAppId: “house”
elasticsearch.ssl.verificationMode: full
elasticsearch.pingTimeout: 1500
elasticsearch.requestTimeout: 30000
elasticsearch.requestHeadersWhitelist: [ authorization ]
elasticsearch.customHeaders: {}
elasticsearch.shardTimeout: 0
elasticsearch.startupTimeout: 5000
pid.file: /my/path/to/kibana.pid
logging.dest: stdout
logging.silent: false
logging.quiet: false
logging.verbose: false
ops.interval: 5000
i18n.defaultLocale: “en”
Can someone help with which all files I should make changes , or is it only sg_config?
And what all changes are to be made keeping in mind the above mentioned ES and Kibana .yml configs?
