Elastic Stack Elasticsearch

Hi All,

I am trying to start Elasticsearch 5.0.0 using ansible playbook and I am getting the below error I tried to by giving ES_JAVA_OPTS="-Xms1g -Xmx1g" in elasticsearch.j2 (template) but still unable to resolve the below error

fatal: [10.247.0.31]: FAILED! => {"changed": true, "cmd": ["sudo", "service", "master_node_elasticsearch", "start"], "delta": "0:00:00.086526", "end": "2016-11-09 07:46:34.015391", "failed": true, "rc": 1, "start": "2016-11-09 07:46:33.928865", "stderr": "", "stdout": "Starting elasticsearch: Error: encountered environment variables that are no longer supported\nUse jvm.options or ES_JAVA_OPTS to configure the JVM\nES_HEAP_SIZE=1g: set -Xms1g and -Xmx1g in jvm.options or add "-Xms1g -Xmx1g" to ES_JAVA_OPTS\n[FAILED]", "stdout_lines": ["Starting elasticsearch: Error: encountered environment variables that are no longer supported", "Use jvm.options or ES_JAVA_OPTS to configure the JVM", "ES_HEAP_SIZE=1g: set -Xms1g and -Xmx1g in jvm.options or add "-Xms1g -Xmx1g" to ES_JAVA_OPTS", "[FAILED]"], "warnings": ["Consider using 'become', 'become_method', and 'become_user' rather than running sudo"]}

Please help us to setup the JVM for ES 5.0.0

Thanks,

Which playbook are you using? The one provided here is not 5.x compatible yet but there is active work on it.

Thanks @ywelsch for showing the active work.:+1:

I will try to setup ES 5.0

Hi @ywelsch

I had a little doubt in setting up ES 5.0 and I am following ES 5.x support active work but getting below error,

fatal: [10.247.0.5]: FAILED! => {"changed": true, "cmd": ["sudo", "service", "master_node_elasticsearch", "start"], "delta": "0:00:00.054053", "end": "2016-11-14 05:09:33.621534", "failed": true, "rc": 7, "start": "2016-11-14 05:09:33.567481", "stderr": "", "stdout": "MAX_LOCKED_MEMORY is set - ES_HEAP_SIZE must also be set", "stdout_lines": ["MAX_LOCKED_MEMORY is set - ES_HEAP_SIZE must also be set"], "warnings": ["Consider using 'become', 'become_method', and 'become_user' rather than running sudo"]}

Though I have given the es_heap_size value in my playbook but still getting the error.

I have attached the my playbook for your reference and somewhere I am doing mistake & pls correct me

  • name: Elasticsearch with custom configuration
    strategy: debug
    #hosts: localhost
    hosts: 10.247.0.5
    remote_user: esadmin
    sudo: yes
    roles:
  • { role: elasticsearch, es_instance_name: "master_node",
    es_config: {
    node.name: "master_node",
    cluster.name: "ES_LOCAL_CLUSTER",
    discovery.zen.ping.unicast.hosts: "10.247.0.5:9301",
    http.port: 9201,
    transport.tcp.port: 9301,
    node.data: true,

    #bootstrap.mlockall: true,
    discovery.zen.ping.multicast.enabled: false,

    }
    }
    vars:
    es_remote_user: esadmin
    es_scripts: true
    es_templates: false
    es_version_lock: false
    es_heap_size: 1g
    es_java_opts: "-Xms1g -Xmx1g"

You don't need to use es_java_opts. But you should probably make sure that jvm.options goes in /etc/elasticsearch/jvm.options. Doesn't seem like this file is working in default.path.conf. I believe there is an open issue about this. Playbook needs modified to support that (It does delete the default jvm.options).

Also make sure there is nothing in /usr/share/elasticsearch/plugins/

Remove this

# TODO: Re-enable when fixed in ES 5.0.1
#- name: Delete Default JVM Options File (5.x)
#  file: dest=/etc/elasticsearch/jvm.options state=absent

And change to this

# TODO: Disable when fixed in ES 5.0.1
- name: Copy jvm.options File for Instance
  template: src=jvm.options.j2 dest=/etc/elasticsearch/jvm.options owner={{ es_user }} group={{ es_group }} mode=0644 force=yes
  notify: restart elasticsearch
  when: es_version | version_compare('5.0', '>=')

Hopefully that helps your situation. That's how I could run 3 process on the same server.

Hey @carrot

I have tried the same setting as you suggested and I could see its trying to start ES from the path
/usr/share/elasticsearch/bin/elasticsearch

but It fails to start ES and I got the following error,

fatal: [10.247.0.5]: FAILED! => {"changed": true, "cmd": ["service", "master_node_elasticsearch", "start"], "delta": "0:00:00.050567", "end": "2016-11-17 01:26:21.900953", "failed": true, "rc": 7, "start": "2016-11-17 01:26:21.850386", "stderr": "", "stdout": "/usr/share/elasticsearch/bin/elasticsearch\nMAX_LOCKED_MEMORY is set - ES_HEAP_SIZE must also be set", "stdout_lines": ["/usr/share/elasticsearch/bin/elasticsearch", "MAX_LOCKED_MEMORY is set - ES_HEAP_SIZE must also be set"], "warnings": ["Consider using service module rather than running service"]}

when I check jvm_options file path it placed in /etc/elasticsearch and heap size value also append to the min & max
