1、首先要把jdk安装好，然后下载elasticsearch-2.3.4.tar.gz
1
wget https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.3.4/elasticsearch-2.3.4.tar.gz

# cd /opt/
# ls
elasticsearch-2.3.4.tar.gzgit-1.8.3.2.tar.gz
# tar zxvf elasticsearch-2.3.4.tar.gz
3、创建用户和用户组(elasticsearch 2.0.0版本后不能以root用户启动。)
1
2
# groupadd elsearch
# useradd elsearch -g elsearch -p elasticsearch
4、把解压好的目录移动到/usr/local/elasticsearch
1
# mv elasticsearch-2.3.4 /usr/local/elasticsearch
5、设置权限
1
chown -R elsearch:elsearch/usr/local/elasticsearch
6、安装es-head插件
1
2
# cd /usr/local/elasticsearch/bin/
# ./plugin –install mobz/elasticsearch-head
7、在浏览器中输入http://localhost:9200，http://localhost:9200/_plugin/head/如下图所示则ES启动成功。
8、若要停止服务，则输入sh elasticsearch stop

# cd /usr/local/elasticsearch/bin
# sh elasticsearch stop
9、安装ik中文分词，首先要安装java 和 elasticsearch
(1)安装maven

# tar zxvf apache-maven-3.3.9-bin.tar.gz
# mv apache-maven-3.3.9 /usr/local/maven
# vim /etc/profile

export PATH=$PATH:$JAVA_HOME/bin
export M2_HOME=/usr/local/maven

# wget -c
# unzip master.zip
# cd elasticsearch-analysis-ik-master/
# cp -Rf config/* ik /usr/local/elasticsearch/config/
# mvn package
# /usr/local/elasticsearch/bin/plugin --install analysis-ik --url file:///alidata/download/elasticsearch-analysis-ik-master/target/releases/elasticsearch-analysis-ik-1.4.1.zip

# cd /usr/local/elasticsearch/config
# vim elasticsearch.yml
index:
analysis:
analyzer:
ik:
alias:
type: org.elasticsearch.index.analysis.IkAnalyzerProvider
ik_max_word:
type: ik
use_smart: false
ik_smart:
type: ik
use_smart: true
index.analysis.analyzer.default.type: ik
(4)重新启动elasticsearch
1
# /usr/local/elasticsearch/bin/elasticsearch -d
(5) ik分词测试，创建一个索引，名为index
1
# curl -XPUT http://localhost:9200/index
为索引index创建mapping

"content": {
"type" : "string",
"boost" : 8.0,
"term_vector" : "with_positions_offsets",
"analyzer" : "ik",
"include_in_all" : true
}
}
}
}'
