1、安装java环境

# yum install -y java java-1.8.0-openjdk-devel# vim /etc/profile.d/java.shexport JAVA_HOME=/usr# source /etc/profile.d/java.sh

2、下载程序包

# wget https://download.elasticsearch.org/elasticsearch/release/org/elasticsearch/distribution/rpm/elasticsearch/2.0.0/elasticsearch-2.0.0.rpm

3、安装elasticsearch

# yum install -y ./elasticsearch-2.0.0.rpm

# vim /etc/elasticsearch/elasticsearch.ymlcluster.name: che001-esnode.name: es03network.host: 11.0.10.20discovery.zen.ping.unicast.hosts: ["11.0.10.18", "11.0.10.19","11.0.10.20"]

5、启动服务

# systemctl start elasticsearch && systemctl enable elasticsearch# netstat -tnlp# jps41408 Jps41328 Elasticsearch# jps -v41328 Elasticsearch -Xms256m -Xmx1g -Djava.awt.headless=true -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseCMSInitiatingOccupancyOnly -XX:+HeapDumpOnOutOfMemoryError -XX:+DisableExplicitGC -Dfile.encoding=UTF-8 -Djna.nosys=true -Des.path.home=/usr/share/elasticsearch41420 Jps -Dapplication.home=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-0.b13.el7_3.x86_64 -Xms8m

6、查看集群状态

# curl -XGET 'http://11.0.10.18:9200/_cluster/health?pretty=true'{ "cluster_name" : "che001-es", "status" : "green", "timed_out" : false, "numb
