安装elasticsearch

使用apt方式安装elaticsearch6.8方便快捷
https://www.elastic.co/guide/en/elasticsearch/reference/6.8/install-elasticsearch.html

wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
sudo apt-get install apt-transport-https
echo "deb https://artifacts.elastic.co/packages/6.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-6.x.list
sudo apt-get update && sudo apt-get install elasticsearch

配置elasticsearch

注意：配置es需要切换到root用户，启动es不需要root用户
配置文件目录 /etc/elasticsearch YAML格式

elasticsearch.yml for configuring Elasticsearch
jvm.options for configuring Elasticsearch JVM settings
log4j2.properties for configuring Elasticsearch logging

设置jvm选项 /etc/elasticsearch/jvm.options

#堆大小 
-Xms2g 最小堆大小
-Xmx2g 最大堆大小

重要的配置项
/etc/elasticsearch/elasticsearch.yml

path.data 数据文件
path.logs 日志文件
cluster.name 集群名称，一个集群对应多个Node
node.name 节点名称 
network.host 绑定的IP地址默认为127.0.0.0

设置开机自启动

sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service

启动和关闭

sudo systemctl start elasticsearch.service
sudo systemctl stop elasticsearch.service

https://www.elastic.co/guide/en/elasticsearch/reference/6.8/deb.html
使用curl测试是否装好

ubuntu@ubuntu:/etc/elasticsearch$ curl localhost:9200
