此文档针对es在centos7环境3节点部署,3节点ip分别为:172.16.10.102.172.16.10.103,172.16.10.104
一、增加host
每个节点下增加host配置
172.16.10.102 HadoopMaster
172.16.10.103 HadoopSlave1
172.16.10.104 HadoopSlave2
二、然后下载es安装包
cd /opt wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.0.tar.gz
三、解压es安装包
tar -zxvf elasticsearch-6.4.0.tar.gz
四、编辑es配置文件(master配置如下,其他2个slave修改node.master:false即可)
vim config/elasticsearch.yml
network.host: 0.0.0.0
discovery.zen.ping_timeout: 120s
client.transport.ping_timeout: 60s
discovery.zen.ping.unicast.hosts: ["172.16.10.102","172.16.10.103", "172.16.10.104"]
cluster.name: escluster
node.name: HadoopMaster
path.data: /opt/elasticsearch-6.4.0/data
path.logs: /opt/elasticsearch-6.4.0/datalog
node.master: true
node.data: true
node.attr.rack: r1
bootstrap.memory_lock: true
bootstrap.system_call_filter: false
http.port: 9200
http.cors.enabled: true
http.cors.allow-origin: "*"
五、修改系统参数
vim /etc/security/limits.conf
新增
- soft nofile 65536
- hard nofile 65536
- soft nproc 65536
- hard nproc 65536
- soft memlock unlimited
- hard memlock unlimited
vim /etc/sysctl.conf
新增
vm.max_map_count=655360
然后重新加载系统参数
sysctl -p
六、使用es用户启动
groupadd es
useradd es -g es-p elasticsearch-6.4.0
chown -R es:es elasticsearch-6.4.0
su es
./elasticsearch -d
七、安装head
在随意个文件夹下 git clone git://github.com/mobz/elasticsearch-head.git
安装nodejs环境
yum -y install nodejs
cd elasticsearch-head/
npm install
npm install -g grunt-cli
grunt server &
Open http://localhost:9100
(如果提示报错[email protected] install: node install.js
)
npm install [email protected] --ignore-scripts 即可
重新启动es程序。
打开网页:http://172.16.10.102:9100(如果head的9200连接不上,检查配置文件的http.cors.enabled: true
http.cors.allow-origin: "*" 是否配置)
