ElasticSearch 安装

environment

CentOS 7.2

ElasticSearch 7.3.0

install

通过 rpm 安装，参考 https://www.elastic.co/guide/en/elasticsearch/reference/current/rpm.html

启动和优化

sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service
sudo systemctl start elasticsearch.service
sudo systemctl stop elasticsearch.service
sudo systemctl status kibana.service

/etc/elasticsearch/jvm.options

-Xms32g
-Xms32g

/etc/elasticsearch/elasticsearch.yml 单机只有一个节点

network.host: 0.0.0.0
cluster.name: my-application  # 集群中的名称
node.name: master  # 该节点名称
cluster.initial_master_nodes: ["master"]

rpm 安装 ElasticSearch 之后的目录结构

/usr/share/elasticsearch  # ES_HOME
/var/log/elasticsearch    # log 目录
/etc/elasticsearch        # config 目录
/var/lib/elasticsearch    # data 目录

plugin elasticsearch-analysis-hanlp

https://github.com/KennFalcon/elasticsearch-analysis-hanlp

建议使用 Elasticsearch 命令行安装插件

./elasticsearch-plugin install file:///home/demo/elasticsearch-analysis-hanlp-7.3.0.zip

插件 在 /usr/share/elasticsearch/plugins/anlysis-hanlp 目录下 配置文件在 /etc/elasticsearch/analysis-hanlp 目录下

修改 hanlp.properties, root 修改为绝对路径 root=/usr/share/elasticsearch/plugins/analysis-hanlp/

然后把 hanlp 的 数据文件复制到 /usr/share/elasticsearch/plugins/analysis-hanlp/data

chown -R elasticsearch:elasticsearch /usr/share/elasticsearch/plugins/
