Elasticsearch is not starting for Search Guard error

shuvo · July 5, 2020, 8:51am

I’m trying to configure Search Guard admin. here is my elasticsearch.yml configurations:

searchguard.ssl.transport.pemcert_filepath: /home/rsa-key-20200528/search-guard-ssl-master/example-pki-scripts/node-0.crt.pem
searchguard.ssl.transport.pemkey_filepath: /home/rsa-key-20200528/search-guard-ssl-master/example-pki-scripts/node-0.key.pem
searchguard.ssl.transport.pemkey_password: changeit
searchguard.ssl.transport.pemtrustedcas_filepath: /home/rsa-key-20200528/search-guard-ssl-master/example-pki-scripts/ca/root-ca.pem
searchguard.ssl.transport.enforce_hostname_verification: false

searchguard.authcz.admin_dn:
  - CN=kirk,OU=client,O=client,L=Test,C=DE

After this configurations, I’m unable to start my elasticsearch. Here is the full error from my “/var/log/elasticsearch/my-application.log” file.

I’m following this and this documentation.

what is wrong here? why elasticsearch is not starting?

srgbnd · July 7, 2020, 4:27pm

Does Elasticsearch user have rights to read the node-0.crt.pem file? I bet he doesn’t.

Another thing, if you don’t use OID in the TLS certificates, don’t forget to configure the searchguard.nodes_dn: Configuring TLS | Security for Elasticsearch | Search Guard

An example of the config for a cluster node:

elasticsearch.yml

node.name: sgssl-0.example.com
network.host: 0.0.0.0
http.port: 9200
cluster.name: es-docker-cluster
discovery.seed_hosts: ["sgssl-1.example.com", "sgssl-2.example.com"]
cluster.initial_master_nodes: ["sgssl-0.example.com", "sgssl-1.example.com", "sgssl-2.example.com"]
bootstrap.memory_lock: true
cluster.routing.allocation.disk.threshold_enabled: false
node.max_local_storage_nodes: 3

xpack.security.enabled: false

searchguard.allow_default_init_sgindex: true
searchguard.audit.type: internal_elasticsearch
searchguard.enable_snapshot_restore_privilege: true
searchguard.check_snapshot_restore_write_privileges: true
searchguard.restapi.roles_enabled: ["SGS_ALL_ACCESS"]
# This is a configuration snippet for the node node1
# This snippet needs to be inserted into the file config/elasticsearch.yml of the respective node.
# If the config file already contains SearchGuard configuration, this needs to be replaced.
# Furthermore, you need to copy the files referenced below into the same directory.
# Please refer to http://docs.search-guard.com/latest/configuring-tls for further configuration of your installation.
