ELK 安装Elasticsearch

ELK栈要安装以下开源组件:

  • Elasticsearch
  • Kibana
  • Beats
  • Logstash (可选)

Logstash是可选的。

安装Elasticsearch

Elasticsearch是一个近实时的全文搜索引擎,它有多种用途,例如作为日志系统。

要下载安装Elasticsearch,打开命令行终端,执行以下命令(deb用于Debian/Ubuntu, rpm用于Redhat/Centos/Fedora, mac用于OS X, linux用于linux, win用于Windows):

deb:

curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.1.0-amd64.deb
sudo dpkg -i elasticsearch-7.1.0-amd64.deb
sudo /etc/init.d/elasticsearch start

rpm:

curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.1.0-x86_64.rpm
sudo rpm -i elasticsearch-7.1.0-x86_64.rpm
sudo service elasticsearch start

mac:

curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.1.0-darwin-x86_64.tar.gz
tar -xzvf elasticsearch-7.1.0-darwin-x86_64.tar.gz
cd elasticsearch-7.1.0
./bin/elasticsearch

linux:

curl -L -O https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.1.0-linux-x86_64.tar.gz
tar -xzvf elasticsearch-7.1.0-linux-x86_64.tar.gz
cd elasticsearch-7.1.0
./bin/elasticsearch

win:

  1. Elasticsearch下载页面下载Elasticsearch 7.1.0 Windows zip文件。
  2. 将zip文件的内容解压到一个目录,例如:C:\Program Files。
  3. 以管理员身份打开命令行窗口,切换到解压目录,例如:
    cd C:\Program Files\elasticsearch-7.1.0
    
  4. 开始Elasticsearch:
    shell
    bin\elasticsearch.bat

确认Elasticsearch启动

要确认Elasticsearch服务是否启动,可以访问端口9200。

curl http://127.0.0.1:9200

在Windows上,如果没有安装cURL,可以用浏览器打开上面的网址。

如果一切正常,可以看到如下响应:
