1. 開好機器後先更新 yum repo

$ sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

 

2. 安裝 elasticsearch https://www.elastic.co/guide/en/elasticsearch/reference/current/setup-repositories.html

$ sudo echo '[elasticsearch-2.x]
name=Elasticsearch repository for 2.x packages
baseurl=https://packages.elastic.co/elasticsearch/2.x/centos
gpgcheck=1
gpgkey=https://packages.elastic.co/GPG-KEY-elasticsearch
enabled=1' > /etc/yum.repo.d/elasticsearch.repo

$ sudo yum install elasticsearch

 

3. 設定開機自動啟動 elasticsearch

$ sudo /bin/systemctl daemon-reload

$ sudo /bin/systemctl enable elasticsearch.service

 

4. 安裝 cloud-aws 外掛 https://www.elastic.co/guide/en/elasticsearch/plugins/2.2/cloud-aws.html

$ sudo yum install java

$ sudo /usr/share/elasticsearch/bin/plugin install cloud-aws

 

5. 修改 elasticsearch.yml 設定檔

cluster.name: {YOUR_CLUSTER_NAME}

node.name: {YOUR_NODE_NAME}

network.host: _ec2_

cloud:
    aws:
        access_key: {YOUR_ACCESS_KEY}
        secret_key: {YOUR_SECERET_KEY}
        region: {YOUR_REGOIN, eg: ap-southeast}

discovery:
    type: ec2
    ec2:
        groups: {YOUR_SECURITY_GROUP}

 

6. 啟動 elasticsearch

$ sudo service elasticsearch start

 

7. 確認已和別台機器連接

$ sudo cat /var/log/messages
