### 1、安装版本与环境 ###

elasticsearch版本: C-6.5.4

elasticsearch目录: /opt/elasticsearch/

centos7服务器，内存要求至少8G.

### 2、三台服务集群 ###

172.17.115.124  master    
 172.17.115.125   master data    
 172.17.115.126  master data

### 3、创建elasticsearch启动账号 ###

> useradd newUser  
> passwd  newUser

### 4、创建数据与日志目录 ###

> mkdir -p /opt/elasticsearch/data/data/
> 
> mkdir -p /opt/elasticsearch/data/logs/

授权

>     chown -R newUser:newUser /opt

### 5、修改elasticsearch配置信息 ###

1）172.17.115.124 配置信息:

cluster.name: my-application
    node.name: node-172-17-115-124
    path.data: /opt/elasticsearch/data/data
    path.logs: /opt/elasticsearch/data/logs
    bootstrap.memory_lock: false
    bootstrap.system_call_filter: false
    network.host: 172.17.115.124
    http.port: 9200
    discovery.zen.ping.unicast.hosts: ["172.17.115.125:9300","172.17.115.124:9300","172.17.115.126:9300"]
    discovery.zen.minimum_master_nodes: 2
    gateway.recover_after_nodes: 3
    node.master: true
    node.data: false
    node.ingest: false
    search.remote.connect: false
    http.cors.enabled: true
    http.cors.allow-origin: "*"

2）172.17.115.125 配置信息:

cluster.name: my-application
    node.name: node-172-17-115-125
    path.data: /opt/elasticsearch/data/data
    path.logs: /opt/elasticsearch/data//logs
    bootstrap.memory_lock: false
    bootstrap.system_call_filter: false
    network.host: 172.17.115.125
    http.port: 9200
    discovery.zen.ping.unicast.hosts: ["172.17.115.125:9300","172.17.115.124:9300","172.17.115.126:9300"]
    discovery.zen.minimum_master_nodes: 2
    gateway.recover_after_nodes: 3
    node.master: true
    node.data: false
    node.ingest: false
    search.remote.connect: false
    http.cors.enabled: true
    http.cors.allow-origin: "*"

3）172.17.115.126 配置信息:

cluster.name: my-application
    node.name: node-172-17-115-126
    path.data: /opt/elasticsearch/data/data
    path.logs: /opt/elasticsearch/data/logs
    bootstrap.memory_lock: false
    bootstrap.system_call_filter: false
    network.host: 172.17.115.126
    http.port: 9200
    discovery.zen.ping.unicast.hosts: ["172.17.115.125:9300","172.17.115.124:9300","172.17.115.126:9300"]
    discovery.zen.minimum_master_nodes: 2
    gateway.recover_after_nodes: 3
    node.master: true
    node.data: false
    node.ingest: false
    search.remote.connect: false
    http.cors.enabled: true
    http.cors.allow-origin: "*"

### 6、启动elasticsearch ###

> ./bin/elasticsearch

或者后台启动

> ./bin/elasticsearch   -d

启动成功之后，用CURL 请求测试集群是否搭建成功。

> curl http://172.17.115.124:9200/\_cat/nodes?v

如下图，172.17.115.126为主节点

说明：  
3台机器的cluster.name值必须一样，node.name值必须不一样。

### 7、head配置 ###

> vi \_site/app.js

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ppYWhhbzExODY_size_16_color_FFFFFF_t_70][]

8、head启动

> \# node\_modules/grunt/bin/grunt server &
> 
> 后台启动
> 
> \# nohup node\_modules/grunt/bin/grunt server  &exit

看到下图，即大工高成![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2ppYWhhbzExODY_size_16_color_FFFFFF_t_70 1][]
