构建elasticsearch集群

初始化系统环境

在/etc/security/limits.conf 增加如下两行：

elasticsearch soft nofile 4096

elasticsearch hard nofile 65536

下载elastic软件包

curl -o elasticsearch https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/tar/elasticsearch/2.3.3/elasticsearch-2.3.3.tar.gz

解压软件包

tar -xvf elasticsearch-2.3.3.tar.gz

初始化运行环境init.sh

<pre name="code" class="html">#!/bin/bash
export ES_HOME=/usr/share/elasticsearch
export CONF_DIR=/etc/elasticsearch
export DATA_DIR=/var/lib/elasticsearch
export LOG_DIR=/var/log/elasticsearch
export PID_DIR=/var/run/elasticsearch
userdel elasticsearch
groupadd elasticsearch
useradd elasticsearch -g elasticsearch
for dir in /usr/share/elasticsearch /etc/elasticsearch  /var/lib/elasticsearch /var/log/elasticsearch /var/run/elasticsearch ;
do
   test ! -d $dir && mkdir -p $dir
   chown elasticsearch:elasticsearch  -R  $dir
done
           

mv elasticsearch-2.3.3.tar.gz /usr/share/elasticsearch

           

修改配置文件

cluster.name: noah-cluster
node.name: host-172-28-0-2
node.rack: r1
network.host: 172.28.0.2
http.port: 9200
discovery.zen.ping.unicast.hosts: ["172.28.0.2","172.28.0.3","172.28.0.4"]
           

启动elasticsearch服务

/usr/share/elasticsearch/bin/elasticsearch &
           

集群内剩余节点参考上述设置，启动即可。
