Centos7安装ELK集群 Centos7安装ELK集群0.准备环境系统：centos7Hadoop分布式部署完毕hive部署完毕准备文件：elasticsearch-7.17.1-linux-x86_64.tar.gzkibana-7.17.1-linux-x86_64.tar.gzlogstash-7.17.1-linux-x86_64.tar.gz1.所有节点安装ElasticSearch1.解压压缩包tar -xzf elasticsearch-7.17.1-linux-x86_64.tar.gz -C /2.添加ElasticSearch的环境变量（每台机都执行）vim /etc/profile #末尾加入环境变量 export ELASTICSEARCH_HOME=/elasticsearch-7.17.1 export PATH=$PATH:$ELASTICSEARCH_HOME/bin #刷新环境变量 source /etc/profile3.修改ElasticSearch环境使用自己的jdkcd /elasticsearch-7.17.1 vim bin/elasticsearch-env #第二行插入java环境变量 JAVA_HOME="/elasticsearch-7.17.1/jdk"4.修改垃圾回收器配置参数vim config/jvm.options #在大约52行 #####修改前###### -XX:+UseConcMarkSweepGC ################ #####修改后###### -XX:+UseG1GC ################5.修改主配置文件设置集群vim config/elasticsearch.yml #####yaml文件，注意格式##### cluster.name: es node.name: node-x
