Download and install the Public Signing Key

rpm --import https://packages.elasticsearch.org/GPG-KEY-elasticsearch

Add the following in your /etc/yum.repos.d/ directory in a file named (for example) elasticsearch.repo

[elasticsearch-1.4]
name=Elasticsearch repository for 1.4.x packages
baseurl=http://packages.elasticsearch.org/elasticsearch/1.4/centos
gpgcheck=1
gpgkey=http://packages.elasticsearch.org/GPG-KEY-elasticsearch
enabled=1

And your repository is ready for use. You can install it with :

yum install elasticsearch

Configure Elasticsearch to automatically start during bootup. If your distribution is using SysV, then you will need to run :

chkconfig --add elasticsearch

Otherwise if your distribution is using systemd :

sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service

安装脚本：

sudo rpm --import https://packages.elasticsearch.org/GPG-KEY-elasticsearch
sudo cat >/etc/yum.repos.d/elasticsearch.repo <<EOF

gpgkey=http://packages.elasticsearch.org/GPG-KEY-elasticsearch
