篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Elasticsearch杂记相关的知识，希望对你有一定的参考价值。

一、安装使用Elasticsearch

准备3个centos7节点

1、安装

1.0 各节点时间需要同步

# /usr/sbin/ntpdate s2c.time.edu.cn

1.1 由于Elasticsearch是java开发，需要先安装JDK环境

这边使用系统默认的openjdk1.7，但是还需要安装1.7的其他包组：
[[email protected] ~]# yum install java-1.7.0-openjdk-devel

设置java环境变量：
[[email protected] ~]# vim /etc/profile.d/java.sh

export JAVA_HOME=/usr

1.2 下载安装rpm包

官方站点：https://www.elastic.co/downloads/past-releases

[[email protected] ~]# wget https://https://download.elastic.co/elasticsearch/elasticsearch/elasticsearch-1.7.2.noarch.rpm

安装
[[email protected] ~]# yum install elasticsearch-1.7.2.noarch.rpm

1.3 修改配置文件

[[email protected] ~]# cd /etc/elasticsearch/
[[email protected] elasticsearch]# vim elasticsearch.yml 

cluster.name: myes1     #集群中的名字

node.name: "master1.com"    #本地节点的名字

index.number_of_shards: 5   #切片数量

index.number_of_replicas: 1 #副本数量

transport.tcp.port: 9300 #集群默认端口9300

1.4 启动

[[email protected] ~]# systemctl daemon-reload

[[email protected] ~]# systemctl start elasticsearch.service

工作端口9200/tcp，集群检测端口9300/tcp已经监听

1.5 定义启动第二个节点

[[email protected] ~]# yum install java-1.7.0-openjdk-devel

设置java环境变量：
[[email protected] ~]# scp /etc/profile.d/java.sh master2:/etc/profile.d/

安装：
[[email protected] ~]# scp elasticsearch-1.7.2.noarch.rpm master2:/root/

[[email protected] ~]# yum install elasticsearch-1.7.2.noarch.rpm

复制master1节点的配置修改：
[[email protected] ~]# scp /etc/elasticsearch/elasticsearch.yml master2:/etc/elasticsearch/

修改配置文件：
[[email protected] ~]# vim /etc/elasticsearch/elasticsearch.yml 

cluster.name: myes

node.name: "master2.com"

启动：
[[email protected] ~]# systemctl start elasticsearch.service

查看状态：

1.6 定义第三个节点

master3配置同master2，注意集群节点名字要一样，node节点改成master3.com即可

1.7 抓包观察集×××互信息

[[email protected] ~]# yum install -y tcpdump

2、查看集群信息（只能通过curl命令与其API进行交互）

2.1 查看节点状态是否正常

[[email protected] ~]# curl -X GET ‘http://10.201.106.131:9200/?preey‘
{
  "status" : 200,
  "name" : "master1.com",
  "cluster_name" : "myes",
  "version" : {
    "number" : "1.7.2",
    "build_hash" : "e43676b1385b8125d647f593f7202acbd816e8ec",
    "build_timestamp" : "2015-09-14T09:49:53Z",
    "build_snapshot" : false,
    "lucene_version" : "4.10.4"
  },
  "tagline" : "You Know, for Search"   #相当于hello world
}

2.2 cat的API显示模式

[[email protected] ~]# curl -X GET ‘http://10.201.106.131:9200/_cat/‘

技术分享图片

2.2.1 显示集群节点：

[[email protected] ~]# curl -X GET ‘http://10.201.106.131:9200/_cat/nodes‘
master2.com 10.201.106.132 7 59 0.01 d m master2.com 
master1.com 10.201.106.131 5 61 0.00 d * master1.com 
master3.com 10.201.106.133 5 71 0.08 d m master3.com

2.2.2 显示详细格式

[[email protected] ~]# curl -X GET ‘http://10.201.106.131:9200/_cat/nodes?v‘

技术分享图片

heap.percent：堆内存  ？？？
ram.percent：内存使用量
load：负载
node.role：节点角色
master：*符号为主节点

2.2.3 查看选项帮助

[[email protected] ~]# curl -X GET ‘http://10.201.106.131:9200/_cat/nodes?help‘

只显示需要的列：
[[email protected] ~]# curl -X GET ‘http://10.201.106.131:9200/_cat/nodes?h=name,ip,port,uptime,heap,current,load‘
master2.com 10.201.106.132 9300   8.1h 0.03 
master1.com 10.201.106.131 9300 452.3d 0.00 
master3.com 10.201.106.133 9300     8h 0.02

2.2.4 查看主节点

[[email protected] ~]# curl -X GET ‘http://10.201.106.131:9200/_cat/master‘
GFN2hX0aQpySOSYqwXD8mw master1.com 10.201.106.131 master1.com 
[[email protected] ~]# curl -X GET ‘http://10.201.106.131:9200/_cat/master?v‘
id                     host        ip             node        
GFN2hX0aQpySOSYqwXD8mw master1.com 10.201.106.131 master1.com 

查看集群健康状态：
[[email protected] ~]# curl -X GET ‘http://10.201.106.131:9200/_cat/health?v‘
epoch      timestamp cluster status node.total node.data shards pri relo init unassign pending_tasks

}
}

查看第二个同学：
[[email protected] ~]# curl -XGET ‘localhost:9200/students/class1/2?pretty‘

put重复ID，会被替换。建议生产环境，使用ID生成器

6.4 更新文档

PUT方法会覆盖原有文档：PUT方法会覆盖原有文档：

修改黄蓉的年龄：
[[email protected] ~]# curl -XPOST ‘localhost:9200/students/class1/2/_update?pretty‘ -d ‘
{
"doc":{"age":22}
}‘
{
  "_index" : "students",
  "_type" : "class1",
  "_id" : "2",
  "_version" : 2
}

查看：
[[email protected] ~]# curl -XGET ‘localhost:9200/students/class1/2?pretty‘
{
  "_index" : "students",
  "_type" : "class1",
  "_id" : "2",
  "_version" : 2,
  "found" : true,
  "_source":{"first_name":"Rong","last_name":"Huang","gender":"Female","age":22,"courses":"Luoying Shenjian"}

6.5 删除文档

[[email protected] ~]# curl -XDELETE ‘localhost:9200/students/class1/2‘
{"found":true,"_index":"students","_type":"class1","_id":"2","_version":3}[[email protected] ~]# 

查看已经没找到ID2的文档信息：
[[email protected] ~]# curl -XGET ‘localhost:9200/students/class1/2?pretty‘
{
  "_index" : "students",
  "_type" : "class1",
  "_id" : "2",
  "found" : false
}

6.6 删除整个索引

查看有哪些索引：
[[email protected] ~]# curl -XGET ‘localhost:9200/_cat/indices?v‘
health status index              pri rep docs.count docs.deleted store.size pri.store.size 
green  open   .marvel-2018.04.13   1   1       4942            0     31.5mb           16mb 
green  open   students             5   1          1            0      7.8kb          3.9kb

删除students索引：
[[email protected] ~]# curl -XDELETE ‘localhost:9200/students‘
{"acknowledged":true}

再查看索引，students已经没了：
[[email protected] ~]# curl -XGET ‘localhost:9200/_cat/indices?v‘

6.7 重新创建文档

[[email protected] ~]# curl -XPUT ‘10.201.106.131:9200/students/class1/1?pretty‘ -d ‘
> {
> "first_name":"Jing",
> "last_name":"Guo",
> "gender":"Male",
> "age":25,
> "courses":"Xianglong Shiba Zhang"
> }‘

[[email protected] ~]# curl -XPUT ‘10.201.106.131:9200/students/class/2?pretty‘ -d ‘
> {
> "first_name":"Rong",
> "last_name":"Huang",
> "gender":"Female",
> "age":23,
> "courses":"Luoying shenjian"
> }‘

7、数据查询

7.1 列出索引下的所有文档

全量查询,较少使用
[[email protected] ~]# curl -XGET ‘localhost:9200/students/_search?pretty‘

qeury body查询方式，能编写更为复杂的查询：
[[email protected] ~]# curl -XGET ‘localhost:9200/students/_search?pretty‘ -d ‘
> {
> "query": { "match_all": {} }
> }‘

7.2 查询所有索引

数据特别多
[[email protected] ~]# curl -XGET ‘localhost:9200/_search?pretty‘

/_search：所有索引；
/INDEX_NAME/_search：单索引；
/INDEX1，INDEX2/_search：多索引；
/s*,t*/_search：通配符查找索引
/students/class1/_search：单类型搜索
/students/class1,class2/_search：多类型搜索

7.3 几种查询方式

1、GET /_search?q=‘Xianglong‘
2、GET /_search?q=‘Xianglong Shiba Zhang‘
3、GET /_search?q=courses:‘Xianglong Shibao Zhang‘
4、GET /_search?q=courses:‘Xianglong‘

前两个：表示在_all域搜索；
后两个：在指定的域上搜索；

7.4 几种查询方式测试

删除
[[email protected] ~]# curl -XDELETE ‘localhost:9200/students/class/1‘

[[email protected] ~]# curl -XDELETE ‘localhost:9200/students/class/2‘
{"found":true,"_index":"students","_type":"class","_id":"2","_version":2}[[email protected] ~]#

}‘
{
  "_index" : "students",
  "_type" : "class1",
  "_id" : "3",
  "_version" : 1,
  "created" : true
}

只要域中带guo，都能搜出来：
[[email protected] ~]# curl -XGET ‘localhost:9200/students/_search?q="Guo"‘

> {
> "name": "GuoXiang",
> "gender": "Female",
> "age": 10,
> "class": "Emei Pai"
> }‘

再次搜索Guo，没有郭襄（切词后的结果）：
[[email protected] ~]# curl -XGET ‘localhost:9200/students/_search?q=name:"Guo"‘
{"took":18,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":2,"max_score":0.19178301,"hits":[{"_index":"students","_type":"class1","_id":"1","_score":0.19178301,"_source":

再加一个人，声明25人之一
[[email protected] ~]# curl -XPUT ‘localhost:9200/students/class1/5‘ -d ‘
> {
> "name": "Xiaolong Nv",
> "gender": "Female",
> "age": 18,
> "description": "one of 25"
> }‘

再搜索25：
[[email protected] ~]# curl -XGET ‘localhost:9200/students/_search?q=25‘
{"took":12,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":2,"max_score":0.11506981,"hits":[{"_index":"students","_type":"class1","_id":"5","_score":0.11506981,"_source":
{
"name": "Xiaolong Nv",
"gender": "Female",
"age": 18,
"description": "one of 25"
}},{"_index":"students","_type":"class1","_id":"1","_score":0.11506981,"_source":
