1.下载解压es和jdk包
[root@node1 ~]# wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.7.1.tar.gz
[root@node1 ~]# tar xvf elasticsearch-6.7.1.tar.gz -C /opt/
[root@node1 ~]# wget https://download.oracle.com/otn-pub/java/jdk/8u202-b08/1961070e4c9b4e26a04e7f5a083f551e/jdk-8u202-linux-x64.rpm?AuthParam=1552723272_02cde009ff2384cfcf01e2c377d085cc
[root@node1 ~]# scp jdk-8u202-linux-x64.rpm node2:/root/ --将jdk传到各节点上
[root@node1 ~]# scp jdk-8u202-linux-x64.rpm node3:/root/ --将jdk传到各节点上
[root@node1 ~]# rpm -ivh jdk-8u202-linux-x64.rpm --在各节点安装jdk
[root@node1 ~]# cd /opt/elasticsearch-6.7.1/
[root@node1 elasticsearch-6.7.1]# useradd wuhan --创建es用户,es不能用root用户启动
[root@node1 elasticsearch-6.7.1]# passwd wuhan
更改用户 wuhan 的密码 。
新的 密码：
无效的密码： 密码少于 8 个字符
重新输入新的 密码：
passwd：所有的身份验证令牌已经成功更新。
[root@node1 elasticsearch-6.7.1]# chown -R wuhan:wuhan /opt/elasticsearch-6.7.1/
[root@node1 elasticsearch-6.7.1]# vim /etc/security/limits.conf
* soft nofile 65535
* hard nofile 65535
[root@node1 elasticsearch-6.7.1]# vim /etc/sysctl.conf
vm.max_map_count=262144
[root@node1 elasticsearch-6.7.1]# sysctl -p
[root@node1 elasticsearch-6.7.1]# vim /opt/elasticsearch-6.7.1/config/elasticsearch.yml
cluster.name: wuhan --设置集群节点名
node.name: node-1 --为每台机器设置node名字,各节点名字不能一样
path.data: /opt/elasticsearch-6.7.1/data --es数据目录
path.logs: /opt/elasticsearch-6.7.1/logs --日志目录
discovery.zen.ping.unicast.hosts: ["node1", "node2", "node3", "node4"]
network.host: 172.16.8.23 --绑定本机的IP地址
http.port: 9200 --指定端口
[root@node1 elasticsearch-6.7.1]#
2.将node1的es文件复制到其它节点(与node1配置一样)
[root@node1 opt]# scp -r elasticsearch-6.7.1 node2:/opt/
[root@node1 opt]# scp -r elasticsearch-6.7.1 node3:/opt/
[root@node2 ~]# chown -R wuhan:wuhan /opt/elasticsearch-6.7.1/
[root@node2 ~]# vim /etc/security/limits.conf
* soft nofile 65535
* hard nofile 65535
[root@node2 ~]# vim /etc/sysctl.conf
vm.max_map_count=262144
[root@node2 ~]# sysctl -p
3.启动各节点的es服务
[root@node1 ~]# su - wuhan
[wuhan@node1 ~]$ cd /opt/elasticsearch-6.7.1/bin/
[wuhan@node1 bin]$ ./elasticsearch -d
[wuhan@node1 bin]# curl http://172.16.8.23:9200
{
"name" : "node-1",
"cluster_name" : "wuhan",
"cluster_uuid" : "_na_",
"version" : {
"number" : "6.7.1",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "2f32220",
"build_date" : "2019-04-02T15:59:27.961366Z",
"build_snapshot" : false,
"lucene_version" : "7.7.0",
"minimum_wire_compatibility_version" : "5.6.0",
"minimum_index_compatibility_version" : "5.0.0"
},
"tagline" : "You Know, for Search"
}
[wuhan@node1 bin]#
4.安装head插件
[root@node1 ~]$ wget https://nodejs.org/dist/v11.13.0/node-v11.13.0-linux-x64.tar.xz
[root@node1 ~]$ tar xvf node-v11.13.0-linux-x64.tar.xz
[root@node1 ~]$ mv node-v11.13.0-linux-x64 /opt/node-v11.13.0
[root@node1 ~]$ vim /etc/profile
export PATH=$PATH:/opt/node-v11.13.0/bin
[root@node1 ~]$ git clone git://github.com/mobz/elasticsearch-head.git
[root@node1 ~]# cd elasticsearch-head/
[root@node1 elasticsearch-head]# npm install

5.修改es配置文件,重启服务
[wuhan@node1 bin]# vim /opt/elasticsearch-6.7.1/config/elasticsearch.yml
http.cors.enabled: true
http.cors.allow-origin: "*"
[wuhan@node1 bin]$ jps

[wuhan@node1 bin]$ kill -9 17849
[wuhan@node1 bin]$ cd /opt/elasticsearch-6.7.1/bin
[wuhan@node1 bin]$ ./elasticsearch -d
6.访问web页面
[root@node1 elasticsearch-head]# grunt server &
[1] 20212
[root@node1 elasticsearch-head]#
错误提示:
