1、定义模板创建索引：

---

---

首先定义好一个模板的例子

{
  "order":14,
  "template":"ids-1",
  "state":"open",
  "settings":{
    "number_of_shards":1
  },
  "mappings":{
    "warnning":{
      "properties":{
        "name":{
          "type":"keyword"
        },
        "createtime":{
            "type":"date",
            "format":"strict_date_optional_time||epoch_millis"
        },
        "category":{
          "type":"keyword"
        },
        "srcip":{
          "type":"keyword"
        },
        "dstip":{
          "type":"keyword"
        }
      }
    }
  }
}

然后使用PUT方法，发送给Elasticsearch。可以使用下图插件：

然后查看一下，模板是否上传成功：

我博客前面的Elasticsearch中曾经有关于模板的介绍，这里因为Elasticsearch的升级改版，要对模板知识做一些修改

#1、新版本的elasticsearch中，模板的index只能有true何false两个选择，与是否分词无关；不分词请把类型（type）设置成keyword。
#2、新版本中不在保留string类型，取而代之的是text类型和keyword类型，text类型可分词，keyword类型不分词。

2、创建索引操作：

3、传入数据

restful api接口，见我写的前面的文章《ELK基础学习》

数据如下：

{
	"name": "ms17-010",
	"createtime": 1540362486002,
	"category": "attack",
	"srcip": "192.168.1.3",
	"dstip": "192.168.1.4"
}

效果如图：

4、Elasticsearch的配置文件简介

这里介绍的是elasticsearch.yml

# ======================== 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   #集群名
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1  #节点名
#
# 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/data   #数据文件路径
#
# Path to log files:
#
#path.logs: /path/to/logs    #日志文件路径
#
# ----------------------------------- Memory -----------------------------------
#
# Lock the memory on startup:
#
#bootstrap.memory_lock: true
#
# 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: 192.168.0.1  #绑定的IP地址
#
# Set a custom port for HTTP:
#
#http.port: 9200    #服务端口  
#
# 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]"]   #  允许访问的地址列表
#
#discovery.zen.ping.unicast.hosts: ["host1", "host2"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
#discovery.zen.minimum_master_nodes:
#
# 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

#  以下是为了避免X-PACK插件与head冲突导致elasticsearch-head无法正常连接elasticsearch而配置的。
http.cors.enabled: true
http.cors.allow-origin: "*"
http.cors.allow-headers: Authorization,X-Requested-With,Content-Length,Content-Type

5、Elasticsearch批量插入数据

---

---

python 有 Elasticsearch 库，可以使用python Elasticsearch库中的helpers中的bulk来解决批量导入的问题，对于数据量大的时候的插入效率会好的多。但缺点也有，批量插入不会获取每一条插入具体成功与否的信息。Python伪代码如下：

from elasticsearch import Elasticsearch
from elasticsearch.helpers import bulk
es = Elasticsearch()
_list = []
_object_json = {
    #...
}
for x in x:
    _list.append(_object_json)
    if len(_list) >= 5000:
        bulk(es, _list)
if len(_list) > 0:
    bulk(es, _list)
