"Bootstrap check failed" still a mystery?

Elastic Stack Elasticsearch
1

Hi,

I read many threads related to "Bootstrap check failed" but didn't get any solution.

I am using elasticsearch for production environment.

below is my ES configuration

clustername: elasticsearch
node.name: xyz
node.master: true
node.data: true
path.data: /var/elasticseaarch/data
patah.logs: /var/elasticsearch/logs
network.host: 192.168.8.12
transport.port: 9300
discovery.zen.ping.unicast.hosts: ["192.168.8.11", "192.168.8.12", "192.168.8.13"]
discovery.zen.minimum_master_node: 2

OS and ES version

ES  version: 5.6.12
Linux Version: Redhat 7.6
Kernel version: 3.10.0

I tried with all the configuration which I got in other threads for example:

network.host: _eth0_
transport.host: localhost

Unfortunately no luck

Error logs are below:

[2018-12-12T14:16:13,023][INFO ][o.e.b.BootstrapCheck ] [ssosearch01] bound or publishing 
to a non-loopback or non-link-local address, enforcing bootstrap checks

[2018-12-12T14:16:13,024][ERROR][o.e.b.Bootstrap ] [ssosearch01] node validation 
exception bootstrap checks failed

I am trying to resolve this issue from the past 2 days.

Any help would be appriciated.

After this line you should see more details about the failure.
Please read https://www.elastic.co/guide/en/elasticsearch/reference/current/bootstrap-checks.html

Please don't post images of text as they are hardly readable and not searchable.

Instead paste the text and format it with </> icon. Check the preview window.

Read this page: https://www.elastic.co/guide/en/elasticsearch/reference/current/_system_call_filter_check.html

try disabling system call filters using this setting " bootstrap.system_call_filter: false" in your elasticsearch.yml file.

Apologies for that. As i mentioned before, logs are in production server which doesn't have internet connectivity i am not able to copy paste the logs.

After adding "bootstrap.system_call_filter: false" i am able to start the service but not able to connect to http://localhost:9200

Error logs:

# curl -XGET 'http://localhost:9200/'
 curl: (7) Failed connect to localhost:9200; Connection refused

But i verified service is running.

Thanks for the reply

Check again the logs and look for the line where port 9200 is mentioned. You'll see what is the IP address to use.

I am getting same IP which i have given in the configuration.

publish_address (192.168.8.12:9200),  bound_addresses (192.168.8.12:9200)
11

So don't run:

curl -XGET 'http://localhost:9200/'

But:

curl -XGET 'http://192.168.8.12:9200/'
12

Yes, It worked

Thanks a lot.
