1，elasticsearch的安装

1，es启动时需要使用非root用户，所有创建一个bigdata用户（如果是root用户安装的话，启动时会有提示 elastic could not run a root的报错）：

#创建用户

useradd bigdata

#为hadoop用户添加密码：

echo 123456 | passwd --stdin bigdata

#将bigdata添加到sudoers

echo "bigdata ALL = (root) NOPASSWD:ALL" | tee /etc/sudoers.d/bigdata

chmod 0440 /etc/sudoers.d/bigdata

#解决sudo: sorry, you must have a tty to run sudo问题，在/etc/sudoer注释掉 Default requiretty 一行

sudo sed -i ‘s/Defaults    requiretty/Defaults:bigdata !requiretty/‘ /etc/sudoers

#创建一个bigdata目录

mkdir /{bigdata,data}

#给相应的目录添加权限

chown -R bigdata:bigdata /{bigdata,data}

###【切换到bigdata用户安装】###

1.安装jdk（jdk要求1.8.20或1.7.55以上）

2.上传es安装包

3.解压es

tar -zxvf elasticsearch-2.3.1.tar.gz -C /bigdata/

4.修改配置

vi /bigdata/elasticsearch-2.3.1/config/elasticsearch.yml

#集群名称，通过组播的方式通信，通过名称判断属于哪个集群

cluster.name: bigdata

#节点名称，要唯一

node.name: es-1

#数据存放位置

path.data: /data/es/data

#日志存放位置

path.logs: /data/es/logs

#es绑定的ip地址

network.host: 192.168.183.111

#初始化时可进行选举的节点

discovery.zen.ping.unicast.hosts: ["node-4.itcast.cn", "node-5.itcast.cn", "node-6.itcast.cn"]

5.使用scp拷贝到其他节点

scp -r elasticsearch-2.3.1/ node-5.itcast.cn:$PWD

scp -r elasticsearch-2.3.1/ node-6.itcast.cn:$PWD

6.在其他节点上修改es配置，需要修改的有node.name和network.host

7.启动es（/bigdata/elasticsearch-2.3.1/bin/elasticsearch -h查看帮助文档）

/bigdata/elasticsearch-2.3.1/bin/elasticsearch -d

8.用浏览器访问es所在机器的9200端口

http://192.168.183.111:9200/

{

"name" : "es-1",

"cluster_name" : "bigdata",

"version" : {

"number" : "2.3.1",

"build_hash" : "bd980929010aef404e7cb0843e61d0665269fc39",

"build_snapshot" : false,

"lucene_version" : "5.5.0"

},

"tagline" : "You Know, for Search"

}

kill `ps -ef | grep Elasticsearch | grep -v grep | awk ‘{print $2}‘`

2，es安装插件下载es插件

/bigdata/elasticsearch-2.3.1/bin/plugin install mobz/elasticsearch-head

[[email protected] es]$ bin/plugin install mobz/elasticsearch-head

NOTE: Unable to verify checksum for downloaded plugin (unable to find .sha1 or .md5 file to verify)

Installed head into /export/servers/es/plugins/head

#本地方式安装head插件

./plugin install file:///home/bigdata/elasticsearch-head-master.zip

#访问head管理页面，插件地址：

http://localhost:9200/_plugin/head/

3，RESTful接口URL的格式：

http://localhost:9200/<index>/<type>/[<id>]

其中index、type是必须提供的。

id是可选的，不提供es会自动生成。

index、type将信息进行分层，利于管理。

index可以理解为数据库；type理解为数据表；id相当于数据库表中记录的主键，是唯一的。

#向store索引中添加一些书籍

curl -XPUT ‘http://192.168.183.111:9200/store/books/1‘ -d ‘{

# 最简单filter查询

curl -XGET ‘http://192.168.183.111:9200/store/books/_search‘ -d ‘{

"query" : {

"filtered" : {

"query" : {

# bool过滤查询，可以做组合过滤查询

# SELECT * FROM books WHERE (price = 35.99 OR price = 99.99) AND (publish_date != "2016-02-06")

# 类似的，Elasticsearch也有 and, or, not这样的组合条件的查询方式

# 格式如下：

#  {

#    "bool" : {

#    "must" :     [],

#    "should" :   [],

#    "must_not" : [],

#    }

#  }

#

# must: 条件必须满足，相当于 and

# should: 条件可以满足也可以不满足，相当于 or

# must_not: 条件不需要满足，相当于 not

curl -XGET ‘http://192.168.183.111:9200/store/books/_search‘ -d ‘{

"query" : {

"filtered" : {

"filter" : {

"bool" : {

"should" : [

{ "term" : {"price" : 35.99}},

{ "term" : {"price" : 99.99}}

],

"must_not" : {

"term" : {"publish_date" : "2015-06-06"}

}

}

}

}

}

}‘

# 嵌套查询

# SELECT * FROM books WHERE price = 35.99 OR ( publish_date = "2016-02-06" AND price = 99.99 )

curl -XGET ‘http://192.168.183.113:9200/store/books/_search‘ -d ‘{

{ "bool" : {

"must" : [

{"term" : {"price" : 99.99}}

]

}}

]

}

}

}

}

}‘

# range范围过滤

# SELECT * FROM books WHERE price >= 20 AND price < 100

# gt :  > 大于

# lt :  < 小于

# gte :  >= 大于等于

# lte :  <= 小于等于

curl -XGET ‘http://192.168.183.111:9200/store/books/_search‘ -d ‘{

"query" : {

"filtered" : {

"filter" : {

"range" : {

"price" : {

"gt" : 20.0,

"lt" : 100.00

"filtered" : {

"filter" : {

"range" : {

"price" : {

"gte" : 20

}

}

}

}

}

}‘

# 另外一种 and， or， not查询

# 没有bool, 直接使用and , or , not

# 注意: 不带bool的这种查询不能利用缓存

# 查询价格既是35.99，publish_date又为"2015-02-06"的结果

curl -XGET ‘http://192.168.183.111:9200/bookstore/books/_search‘ -d ‘{

"query": {

"filtered": {

"filter": {

"and": [

{

"term": {

"price":59.99

}

},

{

"term": {

"publish_date":"2015-02-06"

}

}

]

},

"query": {

"match_all": {}
