solrcloud Cookbook

Build Status

This is a Chef cookbook for Apache Solr.

It was primarily developed for Testing SolrCloud against Solr Master/Slave setup and its features.

Currently it supports only in built Jetty based SolrCloud deployment, more features and attributes will be added over time, feel free to contribute what you find missing!

SolrCloud is the default deployment and Solr Master/Slave setup is not supported by this cookbook.

For Production environment, always prefer the most recent release.

Repository

https://github.com/vkhatri/chef-solrcloud

Supported Apache Solr Version

This cookbook was tested for Apache Solr v4.9, v4.10 and v5.1.0.

v5.2.x support is being added, but not yet fully tested.

Supported Apache Solr Runtime

Currently this cookbook supports only Apache Solr in built Jetty based deployment.

Supported Apache Solr Package Deployment

Currently this cookbook only supports Apache Solr Tarball based deployment.

Supported Apache Solr Cluster Deployment

Currently this cookbook only support SolrCloud Cluster deployment. It does not support Apache Solr Master/Slave Cluster deployment.

Supported JDK Versions

Check Apache Solr Documentation for JDK Version requirement for current Solr version, Oracle JDK 7 is recommended.

Major Changes

Under Development

  • default['solrcloud']['enable_ssl'] is set to false, you need to enable it in wrapper recipe / role / node before using this cookbook version

  • watch out for init.d sysconfig/environment file changes, if you have enabled node['solrcloud']['notify_restart'] it will trigger solr service restart

v0.6.9

  • LWRP zkconfigset provider now refers to resource attribute configset_name instead of name attribute. Existing users might want to test LWRP zkconfigset resources before using this version.

Recipes

  • solrcloud::default - default recipe, used for run_list

  • solrcloud::attributes - derived attributes recipe

  • solrcloud::tarball - install solr

  • solrcloud::config - manages solr configuration

  • solrcloud::service - manages solr service

  • solrcloud::jetty - manages jetty configuration

  • solrcloud::java - install java

  • solrcloud::zkcli - setup zookeeper for zookeeper client binary (zkCli.sh)

      zkcli recipe does not manage zookeeper server and its only purpose
  is to have zookeeper client on all solr nodes

  • solrcloud::user - create solr service user

      solr user is better to be managed by a User management cookbook
  instead of solrcloud for Production environment.

  • solrcloud::zkconfigsets - create/delete solrcloud configSet in zookeeper via LWRP

  • solrcloud::collections - create/delete solrcloud collection on solrcloud node via LWRP

SolrCloud configSet (Zookeeper Configs) LWRP

LWRP - solrcloud_zkconfigset

SolrCloud Zookeeper configSet is managed via LWRP - solrcloud_zkconfigset.

SolrCloud Zookeeper configSets management is enabled by default for all nodes. It means all nodes will get the configSets and will try to manage it against one of the configured zookeeper server via attribute node[:solrcloud][:solr_config][:solrcloud][:zk_host].

All the nodes communicate to a zookeeper cluster, hence attribute
`node[:solrcloud][:manage_zkconfigsets]` & `node[:solrcloud][:manage_zkconfigsets_source]`
does not require to be enabled on all the nodes.

Check Cookbook Advanced Attributes section for attribute details.

zookeeper configSet config changes

LWRP handles config changes by itself. When any change is made to configSet content, configSet will re-upload configSet to zookeeper.

LWRP example

Create a configSet using LWRP:

solrcloud_zkconfigset configset_name
  option option_name
end

Always re create/upload configSet even exists or no update to config files:

solrcloud_zkconfigset configset_name
  force_upload true
  option option_name
end

OR

Set attribute node[:solrcloud][:force_zkconfigsets_upload] to true, which affects all the configSets as resource attribute :force_upload defualt value is set to node[:solrcloud][:force_zkconfigsets_upload].

Delete a configSet using LWRP:

solrcloud_zkconfigset configset_name do
  action :delete
end

configSet via node attribute:

"default_attributes": {
  "solrcloud": {
    "zkconfigsets": {
      "abc": {
        "action": "delete"
      },
      "xyz": {
        "option name": "option value"
      }
    }
  }
}

configSets can either be configured in recipe using LWRP or using node attribute node[:solrcloud][:zkconfigsets].

configSets defined using attribute node[:solrcloud][:zkconfigsets] does not require LWRP.

LWRP Options

SolrCloud Zookeeper cmd Reference: https://cwiki.apache.org/confluence/display/solr/Command+Line+Utilities

Parameters:

  • configset_name (required) - solrcloud zookeeper configSet name
  • action (optional) - default :create, options: :create, :delete
  • user (optional) - configSet directory user permission, default value node[:solrcloud][:user]
  • group (optional) - configSet directory group permission, default value node[:solrcloud][:group]
  • solr_zkcli (optional) - solr in built zkcli.sh for configSet upconfig, default value node[:solrcloud][:zookeeper][:solr_zkcli]
  • zkcli (optional) - zookeeper client zkCli.sh, default value node[:solrcloud][:zookeeper][:zkcli]
  • zkhost (optional) - zookeeper server, default value node[:solrcloud][:solr_config][:solrcloud][:zk_host].first
  • zkconfigsets_home (optional) - configSet directory to sore on solrcloud node, default value node[:solrcloud][:zkconfigsets_home]
  • zkconfigsets_cookbook (optional) - configSet cookbook name, default value node[:solrcloud][:zkconfigsets_cookbook]
  • manage_zkconfigsets (optional) - manage configSet, default value node[:solrcloud][:manage_zkconfigsets]
  • force_upload (optional) - if set always upload configSet to zookeeper, default value node[:solrcloud][:force_zkconfigsets_upload]

LWRP configSet source cookbook/location management

All configSet content must be stored under node[:solrcloud][:zkconfigsets_cookbook]/files/default/config set name/conf/` if not managed separately.

configSets source cookbook is default set to solrcloud and can be changed via attribute node[:solrcloud][:zkconfigsets_cookbook].

If configSets are managed outside of the cookbook, configSet will only get uploaded in case it is missing in the zookeeper. Any update to separately managed configSets are not propogated to zookeeper by default. However, one can use attribute node[:solrcloud][:force_zkconfigsets_upload] to always upload the configSet regardless of the state.

Setting attribute node[:solrcloud][:force_zkconfigsets_upload] or resource attribute :force_upload would always trigger configSet upload to zookeeper. It is better not to enable rsource attribute :force_upload, but instead better to use attribute node[:solrcloud][:force_zkconfigsets_upload] on limited set of nodes.

This may vary environment to environment.

SolrCloud Collection LWRP

LWRP - solrcloud_collection

SolrCloud collection is managed via LWRP - solrcloud_collection.

Create/Delete Collection API does not require to run on all solrcloud cluster nodes, hence attribute

node[:solrcloud][:manage_collections] does not require to be enabled on all the nodes.

Check Cookbook Advanced Attributes section for attribute details.

collection Update/Change

collection LWRP only perform collection action=CREATE|DELETE|RELOAD and does not manage any UPDATE/change in the collection.

To make a change to a collection, first make the change in the LWRP or node attribute node[:solrcloud][:collections][:collection_nam][:attribute_name] for respective attribute.

Once changes are made in Chef cookbook, perform collection UPDATE or respective action call to one of the solrcloud node.

UPDATE call could be tricky and is not managed by Chef to avoid any unexpected behavior.

Re-issuing same command could hinder solrcloud cluster setup and must be re-issued carefully.

LWRP example

Create a collection using LWRP:

solrcloud_collection collection_name
  option option_name
end

Delete a collection using LWRP:

solrcloud_collection collection_name do
  action :delete
end

Reload a collection using LWRP:

solrcloud_collection collection_name do
  action :reload
end

collection via node attribute:

"default_attributes": {
  "solrcloud": {
    "collections": {
      "abc": {
        "action": "delete"
      },
      "def": {
        "action": "reload"
      },
      "xyz": {
        "num_shards": "1",
        "name": "xyz",
        "replication_factor": "1",
        "collection_config_name": "xyz",
        "option name": "value"
      }
    }
  }
}

collections can either be configured in recipe using LWRP or using node attribute node[:solrcloud][:collections].

collections defined using attribute node[:solrcloud][:collections] does not require LWRP.

SolrCloud Deployment Requirement

To deploy solrcloud using this cookbook, below items are required:

  • a zookeeper server or cluster
  • configSet(s) to upload to zookeeper for collection/core
  • collection(s) name to deploy in solrcloud

SolrCloud configSet Cookbook / Environments / Versioning

Directory Structure

SorlCloud configSet stored in zookeeper are configured as file resources.

Each configSet is stored under node[:solrcloud][:zkconfigsets_cookbook]/files/default/configSet name.

configSet folder follows the standard of having a conf folder with all the configuration files.

So, the directory structure will look like - node[:solrcloud][:zkconfigsets_cookbook]/files/default/configSet name/conf.

Managing same configSet for Multiple Environments

Managing configSet configuration across environments can be achieved in different ways, like

  • maintain different node[:solrcloud][:zkconfigsets_cookbook] per environment OR
  • maintain a single cookbook with versioning

Simply, update node[:solrcloud][:zkconfigsets_cookbook] attribute with your configSet cookbook and update metadata.rb file with line:

'depends node[:solrcloud][:zkconfigsets_cookbook]'.

Single Node SolrCloud Test Cluster Deployment

Adjust the attributes according to your requirement. Below mentioned attributes will work just fine for a single node solrcloud cluster.

"default_attributes": {
  "solrcloud": {
	"zk_run": true,
    "port": "8080",
    "setup_user": true,
    "manager": true,
    "zkconfigsets": {
      "samplecollection": {}
    },
    "collections": {
      "samplecollection": {
        "collection_config_name": "samplecollection"
      }
    }
  }
}

Multi Node Manager Attributes

Below attributes are crucial for Multi Node Cluster. It is not advised to enable below solrcloud attributes on all the nodes in the cluster. Like, each new node will trigger a zookeeper configset re-upload. Creating new collection is better off maanged by one node to prevent a false collection state in the cluster.

"default_attributes": {
  "solrcloud": {
  	"manage_collections": true,
  	"manage_zkconfigsets": true,

Multi Node SolrCloud Test Cluster Deployment with zookeeper Cluster

Adjust the attributes according to your requirement. Below mentioned attributes will work just fine for a single node solrcloud cluster.

"default_attributes": {
  "solrcloud": {
    "solr_config": {
      "solrcloud": {
        "zk_host": [
          "zookeeper_ip:zookeeper_port"
        ]
      }
	},
    "port": "8080",
    "setup_user": true,
  	"manage_collections": true,
  	"manage_zkconfigsets": true,
    "zkconfigsets": {
      "samplecollection": {}
    },
    "collections": {
      "samplecollection": {
        "collection_config_name": "samplecollection"
      }
    }
  }
}

Note: You might want to enable attribute "manager": true on limited cluster nodes. In a large cluster, enabling this value on limited nodes would create less overhead for zookeeper.

Multi Node SolrCloud Test Cluster Deployment with embedded zookeeper

Adjust the attributes according to your requirement. Below mentioned attributes will work just fine for a single node solrcloud cluster.

On any one of the cluster node, enable attribute node[:solrcloud][:zk_run] and use its ip address as zookeeper server.

"default_attributes": {
