1.下载软件
mkdir -p /data/soft [root@db-01 /data/soft]# ll -h total 268M -rw-r--r-- 1 root root 109M Feb 25 2019 elasticsearch-6.6.0.rpm -rw-r--r-- 1 root root 159M Sep 2 16:35 jdk-8u102-linux-x64.rpm ps:这两个rpm包可以在下方云盘下载
2.安装jdk
rpm -ivh jdk-8u102-linux-x64.rpm java -version
3.安装ES
rpm -ivh elasticsearch-6.6.0.rpm
4.检查(内存要大于1G，默认配置占用内存1G空间，否则无法启动)
systemctl daemon-reload systemctl enable elasticsearch.service systemctl start elasticsearch.service systemctl status elasticsearch.service netstat -lntup|grep 9200 [root@db01 /data/soft]#netstat -lntup|grep 9200 tcp6 0 0 10.0.0.51:9200 :::* LISTEN 10489/java tcp6 0 0 127.0.0.1:9200 :::* LISTEN 10489/java [root@db-01 ~]# curl 127.0.0.1:9200 { "name" : "d6F9LYu", "cluster_name" : "elasticsearch", "cluster_uuid" : "tDNMEvCXSj-rEy3jTBdAeQ", "version" : { "number" : "6.6.0", "build_flavor" : "default", "build_type" : "rpm", "build_hash" : "a9861f4", "build_date" : "2019-01-24T11:27:09.439740Z", "build_snapshot" : false, "lucene_version" : "7.6.0", "minimum_wire_compatibility_version" : "5.6.0", "minimum_index_compatibility_version" : "5.0.0" }, "tagline" : "You Know, for Search" }
5.Elasticsearch有哪些重要配置
[root@db01 ~]# rpm -qc elasticsearch
/etc/elasticsearch/elasticsearch.yml #主配置文件
/etc/elasticsearch/jvm.options #JVM虚拟机配置
/etc/init.d/elasticsearch #init启动文件
