elasticsearch sql插件安装

ES部署安装 参考 Elasticsearch-5x部署安装

ES-Sql 插件下载地址

插件安装步骤：

1、将elasticsearch-sql-5.3.0.0.zip 解压到es/plugins 和tomcat下，如图：

2 启动ES和tomcat

访问页面：

加载测试数据

curl -XPUT 'http://localhost:9200/users/user/1' -d '{
"user":"kimchy",
"message":"trying out ElasticSearch!"
}'

出现如图问题： 需要更改端口8080 为 es的9200

更改后：

注意：：： ES5.x的插件需要在elasticsearch.yml 加入以下两行

http.cors.enabled: true
http.cors.allow-origin: "*"

另附本次部署的elasticsearch.yml模板一枚，仅供参考：

# ======================== Elasticsearch Configuration =========================
#
# NOTE: Elasticsearch comes with reasonable defaults for most settings.
#       Before you set out to tweak and tune the configuration, make sure you
#       understand what are you trying to accomplish and the consequences.
#
# The primary way of configuring a node is via this file. This template lists
# the most important settings you may want to configure for a production cluster.
#
# Please consult the documentation for further information on configuration options:
# https://www.elastic.co/guide/en/elasticsearch/reference/index.html
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
cluster.name: my-application
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
node.name: node-1
#
# Add custom attributes to the node:
#
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
path.data: /path/to/data1
#
# Path to log files:
#
path.logs: /path/to/logs1
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
#
# Make sure that the heap size is set to about half the memory available
# on the system and that the owner of the process is allowed to use this
# limit.
#
# Elasticsearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
network.host: 192.16.2.79
#
# Set a custom port for HTTP:
#
http.port: 9200
#
# For more information, consult the network module documentation.
#
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
#
discovery.zen.ping.unicast.hosts: ["192.16.2.78:9300", "192.16.2.79:9300","192.16.2.84:9300"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
discovery.zen.minimum_master_nodes: 3
#
# For more information, consult the zen discovery module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
#http.cors.enabled: true
#http.cors.allow-origin: "*"
http.cors.enabled: true
http.cors.allow-origin: "*"
