1.安装
jdk-8u45-linux-x64.tar.gz
elasticsearch-1.7.2.tar.gz
/etc/profile
export JAVA_HOME=/data/program/jdk1.8
export JRE_HOME=/data/program/jdk1.8/jre
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
tar -xzvf elasticsearch-1.7.2.tar.gz
cd elasticsearch-1.7.2/bin
./elasticsearch -d
内存设置
vim elasticsearch.in.sh
if [ "x$ES_MIN_MEM" = "x" ]; then
ES_MIN_MEM=256m
fi
if [ "x$ES_MAX_MEM" = "x" ]; then
ES_MAX_MEM=512m
fi
2.插件安装
./plugin --install mobz/elasticsearch-head
./plugin --install lukas-vlcek/bigdesk/2.5.0
./plugin --install elasticsearch/marvel/latest
网址访问
http://112.124.120.242:9200/_plugin/head
http://112.124.120.242:9200/_plugin/bigdesk
http://112.124.120.242:9200/_plugin/marvel
3.通过插件marvel去调用api接口进行增删改查
#GET _search
#{
# "query": {
# "match_all": {}
# }
#}
PUT http://112.124.120.242:9200/library/
{
"settings":{
"index":{
"number_of_shards":5,
"number_of_replicas":1
}
}
}
PUT http://112.124.120.242:9200/library2/
{
"settings":{
"index":{
"number_of_shards":5,
"number_of_replicas":1
}
}
}
GET /library/_settings
GET /library,library2/_settings
GET /_all/_settings
PUT /library/books/1
{
"title":"eddy books",
"name":{
"first":"eddy",
"last":"tom"
},
"publish_date":"2016-01-09",
"price":"59.99"
}
GET /library/books/1
GET /library/books/1?_source=title,price
POST /library/books/1/_update
{
"doc":{
"price":69.99
}
}
DELETE /library/books/1
DELETE /library/books
DELETE /library
4.批量获取mget
# 同时获取多个文档信息
# 例子：获取index:bank, type:bank_account下面
# ID为1，2，3，4，15，6，28 的文档信息
GET /bank/bank_account/1
GET /bank/bank_account/2
GET /shakespeare/line/3
GET /bank/bank_account/4
GET /shakespeare/line/5
# 数组[]
GET /_mget
{
"docs" : [
{
"_index" : "bank",
"_type" : "bank_account",
"_id" : 1
},
{
"_index" : "bank",
"_type" : "bank_account",
"_id" : 2
},
{
"_index" : "shakespeare",
"_type" : "line",
"_id" : 3
},
{
"_index" : "shakespeare",
"_type" : "line",
"_id" : 4
},
{
"_index" : "shakespeare",
"_type" : "line",
"_id" : 15
},
{
"_index" : "shakespeare",
"_type" : "line",
"_id" : 6
},
{
"_index" : "shakespeare",
"_type" : "line",
"_id" : 28
}
]
}
# 也可以指定_source字段，获取你想要的
GET /_mget
{
"docs" : [
{
"_index" : "shakespeare",
"_type" : "line",
"_id" : 6,
"_source": "play_name"
},
{
"_index" : "shakespeare",
"_type" : "line",
"_id" : 28,
"_source": "play_name"
}
]
}
# 指定多个_source字段，数组的形式[]
GET /_mget
{
"docs" : [
{
"_index" : "shakespeare",
"_type" : "line",
"_id" : 6
},
{
"_index" : "shakespeare",
"_type" : "line",
"_id" : 28,
"_source": ["play_name","speaker","text_entry"]
}
]
}
# 获取相同index相同type下不同ID的文档
GET /shakespeare/line/_mget
{
"docs" : [
{ "_id" : 6 },
{ "_type" : "line", "_id" : 28 }
]
}
# 可以这样简便的写
GET /shakespeare/line/_mget
{
"ids" : [ "6", "28" ]
}
GET /shakespeare/line/_mget
{
"ids" : [ "1", "2", "3", "4", "5", "6", "7" ]
}
5.批量操作bulk
默认是以换行为一条数据解析的
所以不能用已下格式
{"delete":
{
"_index":"library",
"_type":"books",
"_id":"1"
}
}
只能是以下格式
{"delete":{"_index":"library","_type":"books","_id":"1"}}
#多重模式
POST /library/books/_bulk
{ "index": { "_id": 1}}
{ "title":"Elasticsearch: The Definitive Guide","price":5 }
{ "index": { "_id": 2}}
{ "title":"The Elasticsearch cookbook","price":15 }
{ "index": { "_id": 3}}
{ "title":"Elasticsearch Blueprints","price":9 }
{ "index": { "_id": 4}}
{ "title":"Thinking in Python","price":22 }
{ "index": { "_id": 5}}
{ "title":"Thinking in Java","price":7 }
GET /library/
GET /library/books/_mget
{
"ids" : [ "1", "2" , "3", "4", "5"]
}
# 当然还可以有delete ,update等操作
# 注意delete下面没有具体的request body
POST /library/books/_bulk
{ "delete": { "_index": "library", "_type": "books", "_id": "1" }}
{ "create": { "_index": "music", "_type": "classical", "_id": "1" }}
{ "title": "Ave Verum Corpus" }
{ "index": { "_index": "music", "_type": "classical" }}
{ "title": "Litaniac de Venerabili Altaris Sacromento" }
{ "update": { "_index": "library", "_type": "books", "_id": "2"} }
{ "doc" : {"price" : "18"} }
GET /library/books/1
GET /library/books/_mget
{
"ids" : [ "1", "2" , "3", "4", "5"]
}
bulk处理文档大小的最佳值
加载每个节点的RAM中在实际应用中逐次提升文档数目
6.Version版本控制
# Version版本控制
#
#内部版本控制
PUT /library/books/1
{
"title": "Elasticsearch: The Definitive Guide",
"name" : {
"first" : "Zachary",
"last" : "Tong"
},
"publish_date":"2015-02-06",
"price":"59.99"
}
GET /library/books/1
POST /library/books/1/_update
{
"doc": {
"price" : 10
}
}
POST /library/books/1/_update?version=3
{
"doc": {
"price" : 15
}
}
# 外部版本控制机制
#自己手动定义版本号
#但是版本号不能冲突
#版本号大于内部版本号即可
#版本号必须是整数
PUT /library/books/1?version=5&version_type=external
{
"title": "Elasticsearch: The Definitive Guide",
"name" : {
"first" : "Zachary",
"last" : "Tong"
},
"publish_date":"2015-02-06",
"price":"20"
}
PUT /library/books/1?version=6&version_type=external
{
"title": "Elasticsearch: The Definitive Guide",
"name" : {
"first" : "Zachary",
"last" : "Tong"
},
"publish_date":"2015-02-06",
"price":"25"
}
GET /library/books/1
7.映射
# 建立映射
POST /library
{
"settings": {
"number_of_shards": 5,
"number_of_replicas": 1
},
"mappings": {
"books": {
"properties": {
"title": { "type": "string"},
"name": { "type": "string", "index": "not_analyzed"},
"publish_date": {"type": "date", "index": "not_analyzed"},
"price": {"type": "double"},
"number": {"type": "integer"}
}
}
}
}
# 动态映射
PUT /library
{
"mappings": {
"books": {
"dynamic": "strict",
"properties": {
"title": { "type": "string" },
"name": { "type": "string", "index": "not_analyzed"},
"publish_date": {"type": "date", "index": "not_analyzed"},
"price": {"type": "double"},
"number": {
"type": "object",
"dynamic": true
}
}
}
}
}
GET /library/
# 获取某个索引的映射信息
GET /library/_mapping
GET /bank/_mapping/
# 获取某个索引下某个type的映射信息
GET /library/_mapping/books
# 获取这个集群内所有的映射信息
GET /_all/_mapping
# 获取这个集群内某两个或多个type的映射信息
GET /_all/_mapping/books,bank_account
# 更新修改Mapping映射
# 很遗憾，mapping一旦建立，就不能修改现有的字段映射
# 如果要推倒现有的映射，你得重新建立一个索引，然后重新定义映射
# 然后把之前索引里的数据导入到新建立的索引里
# ---------具体的方法----------
# 1. 给现有的索引定义一个别名，并且把现有的索引指向这个别名，运行步骤2
# 2. 运行 ： PUT /现有索引/_alias/别名A
# 3. 新创建一个索引，定义好最新的映射
# 4. 将别名指向新的索引，并且取消之前索引的指向，运行步骤5
# 5. 运行： POST /_aliases
# {
# "actions": [
# { "remove": { "index": "现有索引名", "alias": "别名A" }},
# { "add": { "index": "新建索引名", "alias": "别名A" }}
# ]
# }
#
# 注：通过这几个步骤就实现了索引的平滑过度，并且是零停机的
#
#删除映射
DELETE /library/books
DELETE /library/books/_mapping
DELETE /library/_mapping/books,bank
