admin 提交于 周二, 05/22/2018 - 11:19

1. 下载安装包

到官网下载安装包:https://www.elastic.co/downloads/elasticsearch

我下载的是用在Ubuntu上的deb包。

 

$ wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.2.4.deb

$ sudo dpkg -i elasticsearch-6.2.4.deb

2. 配置Elasticsearch为启动服务

sudo systemctl enable elasticsearch.service

3. 配置(可选)

$ sudo vi /etc/elasticsearch/elasticsearch.yml

 

. . .
cluster.name: mycluster1
node.name: "My First Node"
. . .

服务默认占用内存1G,因为我的服务器内存小,改成256M:

$ sudo vi /etc/elasticsearch/jvm.options

-Xms256m
-Xmx256m

4. 启动服务

$ sudo systemctl start elasticsearch

5. 测试

$ curl -X GET 'http://localhost:9200'

 

$ curl -XGET 'http://localhost:9200/_nodes?pretty'

 

$ curl -H 'Content-Type: application/json' -X POST 'http://localhost:9200/tutorial/helloworld/1' -d '{ "message": "Hello World!" }'

$ curl -X GET 'http://localhost:9200/tutorial/helloworld/1'

6. 安装中文分词

/usr/share/elasticsearch$ sudo ./bin/elasticsearch-plugin install https://github.com/medcl/elasticsearch-analysis-ik/releases/download/v6.2.4/elasticsearch-analysis-ik-6.2.4.zipes/download/

$ sudo service elasticsearch restart

用法详见:https://github.com/medcl/elasticsearch-analysis-ik/

7. 查看索引状态

curl -XGET http://localhost:9200/_cat/indices?pretty

8. 官方教程及API

进一步的用法参考API文档:https://www.elastic.co/guide/en/elasticsearch/reference/current/docs.html
