1.环境准备

2.安装JDK

rpm -ivh jdk-8u181-linux-x64.rpm

3.安装ES

rpm -ivh elasticsearch-6.5.4-x86_64.rpm

4.配置内存锁定

systemctl edit elasticsearch.service
[Service]
LimitMEMLOCK=infinity

5.编写配置文件

#es_node_1配置：
vim  /etc/elasticsearch/elasticsearch.yml 
cluster.name: zhongtai_group
node.name: es_node_1
path.data: /es/data
path.logs: /es/logs
bootstrap.memory_lock: false
network.host: 0.0.0.0
http.port: 9200
discovery.zen.ping.unicast.hosts: ["10.0.0.11","10.0.0.12","10.0.0.13"]
discovery.zen.mininum_master_nodes: 2
bootstrap.system_call_filter: false
################################################
#es_node_2配置：
vim  /etc/elasticsearch/elasticsearch.yml 
cluster.name: zhongtai_group
node.name: es_node_2
path.data: /es/data
path.logs: /es/logs
bootstrap.memory_lock: false
network.host: 0.0.0.0
http.port: 9200
discovery.zen.ping.unicast.hosts: ["10.0.0.11","10.0.0.12","10.0.0.13"]
discovery.zen.mininum_master_nodes: 2
bootstrap.system_call_filter: false
################################################
#es_node_3配置：
vim  /etc/elasticsearch/elasticsearch.yml 
cluster.name: zhongtai_group
node.name: es_node_3
path.data: /es/data
path.logs: /es/logs
bootstrap.memory_lock: false
network.host: 0.0.0.0
http.port: 9200
discovery.zen.ping.unicast.hosts: ["10.0.0.11","10.0.0.12","10.0.0.13"]
discovery.zen.mininum_master_nodes: 2
bootstrap.system_call_filter: false

6.创建目录授权

(尽量选择数据盘)

mkdir -p /es/data
mkdir -p /es/logs
chown -R elasticsearch:elasticsearch /es/
chown -R elasticsearch:elasticsearch /etc/init.d/elasticsearch

7.启动服务

systemctl daemon-reload
systemctl restart elasticsearch.service

8.集群验证

netstat -tnulp|grep 9200
netstat -tnulp|grep 9300

浏览器访问：http://${es_ip}:9200/_cat/nodes

或者curl http://${es_ip}:9200/_cluster/health?pretty

注意：green代表正常。
