本文主要是介绍Ubuntu elastic安装启动,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
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
ERROR: [2] bootstrap checks failed. You must address the points described in the following [2] lines before starting Elasticsearch. bootstrap check failure [1] of [2]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144] bootstrap check failure [2] of [2]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured [2022-07-20T11:16:48,526][INFO ][o.e.x.m.p.NativeController] [elastic-node-1] Native controller process has stopped - no new native processes can be started
解决:
解决[1] of [2] sudo vim /etc/sysctl.conf vm.max_map_count=655360 sudo sysctl -p 解决[2] of [2] config/elasticsearch.yml #cluster.name: my-application #node.name: node-1 #cluster.initial_master_nodes: ["node-1", "node-2"] ---> cluster.name: elastic-my-application node.name: elastic-node-1 cluster.initial_master_nodes: ["elastic-node-1"]
4. 其他配置
config/elasticsearch.yml #network.host: 192.168.0.1 #http.port: 9200 ---> network.host: 0.0.0.0 //跨域访问 http.port: 9200
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
