只需按照此链接中所述的步骤进行操作即可。

1. Yum仓库的设置。

# rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch

# vim /etc/yum.repos.d/elasticsearch.repo

baseurl=http://packages.elastic.co/elasticsearch/2.x/centos
gpgcheck=1
gpgkey=http://packages.elastic.co/GPG-KEY-elasticsearch
enabled=1

2. 安装

# yum install elasticsearch

3. 启动

# /etc/init.d/elasticsearch start

Starting elasticsearch:                                    [  OK  ]

4. 自动启动设置

# chkconfig --add elasticsearch

5. 更改设置

設定文件位於 /etc/elasticsearch/elasticsearch.yml。
本次設定為本地的Vagrant IP，端口則維持不變。

+network.host: 192.168.33.10

# /etc/init.d/elasticsearch restart
