原文地址：新版elasticsearch的插件安装

安装

 yum localinstall elasticsearch-6.1.1.rpm -y
 mkdir -p /elk/{data,logs} && chown -R elasticsearch.elasticsearch /elk

配置

grep '^[a-Z]' /etc/elasticsearch/elasticsearch.yml
cluster.name: yoho8elk      #ELK的集群名称，名称相同即属于是同一个集群
node.name: manager-node-1   #本机在集群内的节点名称ode-1
path.data: /elk/data        #数据保存目录
path.logs: /elk/logs        #日志保存目录
bootstrap.memory_lock: true     #服务启动的时候锁定足够的内存，防止数据写入swap,可能会导致云主机报错.可以不填写.
network.host: 0.0.0.0       #监听 10.0.1.0网段的
http.port: 9200         
discovery.zen.ping.unicast.hosts: ["10.0.1.100", "10.0.1.24"]

修改内存限制，并同步配置文件：
https://www.elastic.co/guide/en/elasticsearch/reference/current/heap-size.html

vim jvm.options
-Xms1g
-Xmx1g
#官方配置文档最大建议30G以内。

修改节点2的配置文件。

[root@test-manager elasticsearch]# scp elasticsearch.yml test-web04:/etc/elasticsearch/
[root@test-web04 elasticsearch]# grep '^[a-Z]' /etc/elasticsearch/elasticsearch.yml
cluster.name: yoho8elk
node.name: test-web04-node-2
path.data: /elk/data
path.logs: /elk/logs
bootstrap.memory_lock: true     #在云主机上加上这个参数可能会报错。
network.host: 0.0.0.0           #监听 0.0.0.0网段的
http.port: 9200
discovery.zen.ping.unicast.hosts: ["10.0.1.100", "10.0.1.24"]

设置java路径

ln -sv /application/jdk/bin/java* /usr/local/sbin/
