ELK系列一：CentOS7安装elasticsearch5.X

本文介绍如何通过Elasticsearch的RPM包或者RPM源在CentOS7上安装Elasticsearch。

通过RPM源安装Elasticsearch5.x

导入Elasticsearch的PGP Key

下载和安装Elasticsearch的PGP Key

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

配置Elasticsearch的RPM源

在/etc/yum.repo.d/目录下创建一个名为elasticsearch.repo 的文件，文件内容如下：

[elasticsearch-5.x]
name=Elasticsearch repository for 5.x packages
baseurl=https://artifacts.elastic.co/packages/5.x/yum
gpgcheck=1
gpgkey=https://artifacts.elastic.co/GPG-KEY-elasticsearch
enabled=1
autorefresh=1
type=rpm-md

配置好源后，可以用如下命令安装elasticsearch:

sudo yum install elasticsearch

手动rpm安装elasticsearch

#下载elasticsearch-5.3.0.rpm
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.3.0.rpm
#sha1sum校验
sha1sum elasticsearch-5.3.0.rpm
#安装elasticsearch
sudo rpm --install elasticsearch-5.3.0.rpm

启动Elasticsearch

#设置开机自启动
sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable elasticsearch.service
#启动elasticsearch
sudo systemctl start elasticsearch.service
#停止elasticsearch
systemctl stop elasticsearch

配置防火墙默认端号9200

sudo firewall-cmd --permanent --add-port=9200/tcp #把端口号9200加入到防火墙例外
sudo firewall-cmd --reload #重新加载防火墙

验证elasticsearch运行状况

可以通过发送HTTP请求方式验证：

curl -XGET 'localhost:9200/?pretty'

当你看到如下消息时表示elasticsearch已在本机成功运行：

{
  "name" : "Cp8oag6",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "AT69_T_DTp-1qgIJlatQqA",
  "version" : {
    "number" : "5.3.0",
    "build_hash" : "f27399d",
    "build_date" : "2016-03-30T09:51:41.449Z",
    "build_snapshot" : false,
    "lucene_version" : "6.4.1"
  },
  "tagline" : "You Know, for Search"
}
