Need help running Ansible Playbook to install Elastic Search

Elastic Stack Elasticsearch
1

Looking at https://github.com/elastic/ansible-elasticsearch I am trying to install elastic search.

I have run command

ansible-galaxy install elastic.elasticsearch

Now I have the following file, I added the two parameters es_api_basic_auth_username and es_api_basic_auth_password and now trying to run the playbook.

[siddis14@adwnode1 ~]$ cat elastic.yml

  • name: Elasticsearch with custom configuration
    hosts: localhost
    roles:
    • role: elastic.elasticsearch
      vars:
      es_instance_name: "node1"
      es_data_dirs:
      • "/opt/elasticsearch/data"
        es_log_dir: "/opt/elasticsearch/logs"
        es_config:
        node.name: "node1"
        cluster.name: "custom-cluster"
        discovery.zen.ping.unicast.hosts: "localhost:9301"
        http.port: 9201
        transport.tcp.port: 9301
        node.data: false
        node.master: true
        bootstrap.memory_lock: true
        es_scripts: false
        es_templates: false
        es_version_lock: false
        es_heap_size: 1g
        es_start_service: false
        es_plugins_reinstall: false
        es_api_port: 9201
        es_plugins:
      • plugin: ingest-geoip
        proxy_host: proxy.example.com
        proxy_port: 8080
        es_api_basic_auth_username: elastic
        es_api_basic_auth_password: elastic

when I run this I get stuck on a task error. I dont know what to do at this point

I was able to get further in the installation by adding hosts: es_master

Now I am getting a weird path error for java during check which doesnt make sense

Looking at the path I have these files installed via rpms

[siddis14@adwnode1 ~]$ ls -l /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.131-2.b11.el7_3.x86_64/jre/bin/java
-rwxr-xr-x 1 root root 7336 Apr 13 2017 /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.131-2.b11.el7_3.x86_64/jre/bin/java

[siddis14@adwnode1 ~]$ ls -l /usr/lib/jvm/java-1.8.0-oracle-1.8.0.131-1jpp.1.el7_3.x86_64/jre/bin/java
-rwxr-xr-x 1 root root 7734 Apr 6 2017 /usr/lib/jvm/java-1.8.0-oracle-1.8.0.131-1jpp.1.el7_3.x86_64/jre/bin/java

These are the rpms installed in my system

[siddis14@adwnode1 ~]$ rpm -qa | grep java-1.8.0
java-1.8.0-openjdk-devel-1.8.0.131-2.b11.el7_3.x86_64

Hi @Shahzeb_Siddiqui

Looks like you ran into a genuine bug with the ansible playbook which I have fixed in Only use the first found java version if there are multiple installed by Crazybus · Pull Request #493 · elastic/ansible-elasticsearch · GitHub. Thanks for finding and reporting it!

Since it looks like you already have java installed on this machine I think you might want to be disabling the java install from this role. You can do this by setting es_java_install: false

Taken from the additional configuration section in the readme.

  • es_java_install If set to false, Java will not be installed. (true (default) or false)
