Ubuntu Elasticsearch安装启动
1. 下载了安装包elasticsearch-8.3.2-linux-x86_64.tar
tar -xf后启动报warning : ignoring JAVA_HOME=/usr/lib/jdk8/jdk1.8.0_251; using bundled JDK
原因大概是e8不支持java8
2. 重新下载安装包elasticsearch-7.17.2-linux-x86_64.tar,解压后运行./bin/elasticsearch报错
[2022-07-20T11:05:03,954][ERROR][o.e.i.g.GeoIpDownloader ] [vm-10-15-7-72] exception during geoip databases update java.net.SocketTimeoutException: connect timed out
解决:
config/elasticsearch.yml ingest.geoip.downloader.enabled: false(注意false前必须有空格)
3. 再运行./bin/elasticsearch报错

4. 其他配置
config/elasticsearch.yml
#network.host: 192.168.0.1
#http.port: 9200
--->
network.host: 0.0.0.0
http.port: 9200
http.cors.enabled: true //表示是否支持跨域,默认为false
http.cors.allow-origin: "*" //当设置允许跨域,默认为*,表示支持所有域名
node.master: true #该节点是否是master,true表示是的,false表示否,默认是true
node.data: true #该节点是否存储数据,默认true表示是的
transport.tcp.port: 9300 #节点之间通信的端口,默认为9300
xpack.security.enabled: false
5. 在浏览器访问 http://x.x.x.72:9200

6.后台运行
