CentOS7部署ElasticSearch 2.1.1集群

CentOS7部署ElasticSearch-2.1.1集群系统规划

所有节点检查java版本
[root@node160~]# java  -version
javaversion "1.8.0_40"
Java(TM)SE Runtime Environment (build 1.8.0_40-b26)
JavaHotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)
 
所有节点配置hosts文件
192.168.1.160  node160
192.168.1.161  node161
192.168.1.162  node162
所有节点安装ElasticSearch
[root@node160 ~]# mkdir  /opt/elk
[root@node160~]# cd /opt/elk
[root@node160~]#  wget https://download.elasticsearch.org/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.1.1/elasticsearch-2.1.1.tar.gz
 
[root@node160elk]# tar xf  elasticsearch-2.1.1.tar.gz
创建启动elasticsearch用户
[root@node160bin]# groupadd elk
[root@node160bin]# useradd elk -g elk -p elasticsearch
[root@node162elk]# chown  -R elk.elk  elasticsearch-2.1.1
[root@node160elk]# passwd  elk
更改用户 elk 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@node160elk]#
启动elasticsearch
[root@node162elasticsearch-2.1.1]# su  elk
[elk@node162elasticsearch-2.1.1]$ bin/elasticsearch

所有节点配置elk启动内存
[root@node160bin]# vi  elasticsearch.in.sh
ES_MIN_MEM=2g
ES_MAX_MEM=2g
 
所有节点配置elk集群模式
[root@node160config]# vi  elasticsearch.yml
cluster.name: elasticsearch
node.name: node160
node.cluster: true      //指定master服务器
network.host: 192.168.1.160
discovery.zen.ping.unicast.hosts:["node160", "node161","node162"]
 
[root@node161 config]# vi  elasticsearch.yml
