4.三台分别配置 vim config/elasticsearch.yml

cluster.name: xxx

node.name: "elasticsearch1"

node.master: true

node.data: true

path.data: /home/elasticsearch-5.3.0/data

path.logs: /home/elasticsearch-5.3.0/logs

#从5开始也不支持这个配置了

#bootstrap.mlockall: true

network.host: 192.168.1.200

http.port: 9200

transport.tcp.port: 9300

#从5开始也不支持这个配置了

#discovery.zen.ping.multicast.enabled: false

#discovery.zen.ping.unicast.hosts: ["10.105.219.150", "10.105.219.151:9300", "10.105.219.207:9300"]

discovery.zen.ping.unicast.hosts: ["192.168.1.200", "192.168.1.201", "192.168.1.202"]

#从5开始索引的配置不能配在yml中了

#index.number_of_shards: 3

检查集群状态 http://192.168.1.200:9200/_cluster/health?pretty=true http://192.168.1.201:9200/_cluster/health?pretty=true http://192.168.1.202:9200/_cluster/health?pretty=true

安装head： 从5开始，head不再是一个插件形式安装，head作为独立的一个服务，需要单独安装：

yum install git -y

cd /home/elasticsearch-5.3.0/

git clone git://github.com/mobz/elasticsearch-head.git

cd elasticsearch-head

npm install -g grunt #(执行这条之前请看下面注意)

注意：目前centos7还不能用yum安装nodejs和npm，需要手动安装

安装nodejs：

去这里下载编译好的包，https://nodejs.org/download/release/latest-v7.x/

然后解压，把里面的bin添加到path即可

安装npm：

#使用如下命令（https://docs.npmjs.com/README#fancy-install-unix- 这个网址中有说明）

sudo curl -L https://npmjs.org/install.sh | sh

修改elasticsearch-head的连接地址: 目录：elasticsearch-head/_site/app.js

this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://localhost:9200";

把localhost修改成你es的服务器地址，如:

this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://192.168.1.x:9200";

cd /home/elasticsearch-5.3.0/elasticsearch-head/

执行npm install下载依赖的包：(这句其实不用也行)

npm install

启动：

nohup grunt server &
