环境搭建
Ubuntu 14.04.5 LTS
Elasticsearch 7.2.0
jdk1.8.174 (不需要,7.X已经集成jdk)
ElasticSearch 安装
- 官方文档:https://www.elastic.co/guide/...
- 下载
curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.2.0-linux-x86_64.tar.gz
- 解压
tar -xvf elasticsearch-7.2.0-linux-x86_64.tar.gz
- 后续所有操作都在 elasticsearch-7.2.0 目录里面进行
cd ./elasticsearch-7.2.0/
- 编辑 ./config/elasticsearch.yml
# 添加或修改
node.name: node-1
network.host: 0.0.0.0
http.port: 9200
cluster.initial_master_nodes: ["node-1"]
- 修改系统配置,编辑 /etc/sysctl.conf
# 添加或修改
# sudo sysctl -p 使修改生效
vm.max_map_count = 262144
//使生效
sudo sysctl -p /etc/sysctl.conf
- 修改 ECS 安全组,放行 9200 端口
- 启动 elasticsearch (不要使用root用户启动)
./bin/elasticsearch
- 浏览器访问 http://112.外.外.外:9200/,可以看到如下内容
{
"name" : "node-1",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "npPY-fmfRwqJKLKA30ym3Q",
"version" : {
"number" : "7.2.0",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "508c38a",
"build_date" : "2019-06-20T15:54:18.811730Z",
"build_snapshot" : false,
"lucene_version" : "8.0.0",
"minimum_wire_compatibility_version" : "6.8.0",
"minimum_index_compatibility_version" : "6.0.0-beta1"
},
"tagline" : "You Know, for Search"
}
- 关闭 elasticsearch
# 查询
sudo ps aux | grep elasticsearch
# 关闭
kill pid
常用配置
# url
http://112.xx.xx.xx:9200/_cluster/settings?include_defaults
# Kibana
GET /_cluster/settings?include_defaults
- 控制 fielddata 允许内存大小(elasticsearch.yml )
# 控制fielddata允许内存大小,达到HEAP 40% 自动清理旧cache
indices.fielddata.cache.size: 40%
- jvm 堆大小(jvm.options)
-Xms10g
-Xmx10g
插件
- 查看已安装哪些插件
./bin/elasticsearch-plugin list
- 安装 analysis-icu 插件(分词器)
./bin/elasticsearch-plugin install analysis-icu
- 重启 elasticsearch,访问 http://112.外.外.外:9200/_cat/plugins,可以看到如下内容
node-1 analysis-icu 7.2.0
- 用句子测试分词情况
GET /_analyze
{
"analyzer": "icu_analyzer",
"text": "商品价值是凝结在商品中的一般的、无差别的人类劳动,由供给方的社会必要劳动时间决定。"
}
