Linux下elasticsearch集群安装，以及管控台head安装

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

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
