Elasticsearch, Logstash, Kibana (ELK) 搭建

本文主要是介绍Elasticsearch, Logstash, Kibana (ELK) 搭建，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

ELK的搭建有几种方式，概括下：
1. 下载将ELK 组成一起的包
2. 分别安装E,L,K
3. 将ELK装在Docker中。
我还是比较喜欢第三种，就主要介绍第三种。

1 increase the limits about max_map_count

On Linux, you can increase the limits by running the following command as root:
sysctl -w vm.max_map_count=262144

2 start elk container

 docker run -p 5601:5601 -p 9200:9200 -p 5044:5044 -it --name elk sebp/elk

3 login in container and run logstash

docker exec -it elk /bin/bash

At the prompt, enter

/opt/logstash/bin/logstash --path.data /tmp/logstash/data \-e 'input { stdin { } } output { elasticsearch { hosts => ["localhost"] } }'

Wait for Logstash to start (as indicated by the message The stdin plugin is now waiting for input:

this is dumy data

if failed to start logstash, have below error:
Logstash could not be started because there is already another instance using the configured data directory. If you wish to run multiple instances, you must change the “path.data” setting.

do: service logstash stop, then rerun .

4 open kibana
You can now browse to Kibana’s web interface at http://:5601 (e.g. http://localhost:5601 for a local native instance of Docker).

Make sure that the drop-down “Time-field name” field is pre-populated with the value @timestamp, then click on “Create”, and you’re good to go.
