Kibana + Logstash + Elasticsearch log query system, kibanalostash
The purpose of this platform is to facilitate log query During O M and R D. Kibana is a free web shell. Logstash integrates various log collection plug-ins and is also an excellent regular-cut log tool. Elasticsearch is an open-source search engine framework (supporting cluster architecture ).

First, let's look at the overall framework of elasticsearch:
Elasticsearch is a distributed search framework developed based on Lucene and has the following features:
Distributed index and search
Automatic Index sharding and load balancing
Automatic Machine discovery and cluster creatio
Preface:In the Web application or background data management, with the increase of data volume, the application of search engine especially full-text search engine is more and more urgent. Based on technology and cost considerations, we are not able to develop a search engine to meet our needs, fortunately, the industry has a number of excellent open source search engine for us to use, Elasticsearch is one of them.Introduction:Elasticsearch is an open

Elasticsearch is used to build highly available and scalable systems. Elasticsearch can provide better performance from more powerful hardware by purchasing better servers (vertical scaling) or more servers (horizontal scaling, however, vertical scaling also has some limi
Elasticsearch requires a minimum of 7 versions of Java, and the Oracle JDK 1.8.0_73 version is recommended when writing this article. Java installation and platform-related, so this article does not intend to describe how to install Java on each platform. Before you install Elasticsearch, run the following command to check your Java version:

ElasticSearch-Basic Concepts
For articles translated by others, it is very important to master the following basic concepts for learning Elasticsearch. You can try to align the following concepts with MySQL (databases, tables, data rows, fields.
Basic Concepts
Elasticsearch has several core concepts. Understanding these concepts from the very beginning will be of
Full-text search engine Elasticsearch getting started tutorial,
Full-text search is the most common requirement. Open-source Elasticsearch (hereinafter referred to as Elastic) is the first choice for full-text search engines.
It can quickly store, search, and analyze massive data volumes. Wikipedia, Stack Overflow, and Github all use it.
The underlying layer of Elastic is the Open Source library Lucene.
ElasticSearch, referred to as ES, is a lucene-based distributed full-text Search server, and SQL Server full-text index (fulltext index) a bit similar, are based on word segmentation and segmentation of the full-text search engine, with participle, synonym, stem query function , but ES inherently has distributed and real-time properties.One, install the Java SE EnvironmentInstall the Java JDK and configure the Java_home environment variables:1, downlo
Elasticsearch is a distributed, restful search and Analysis server, like Apache SOLR, which is a lucence-based index server, but I think the advantage of Elasticsearch versus SOLR is:
Lightweight: Easy to install, download the file after a command can be started;
Schema Free: You can submit JSON objects of any structure to the server, using Schema.xml to specify the index structure in SOLR;

ElasticSearch 2 (9)-a summary of the story under ElasticSearch (a plot search)First top-down, after the bottom-up introduction of the elasticsearch of the bottom of the working principle, to try to answer the following questions:
Why doesn't my search *foo-bar* match foo-bar ?
Why do you add more files to compress indexes (index)?
Why does
Before you introduce the usage of Elasticsearch, let's talk about why you should use it. First of all to learn the search engine, certainly inevitably have heard LUCENE,SOLR and Elasticsearch are based on it. Spinx many articles, but the database is too intrusive (plug-in mode). Elasticsearch is one of the most popular distributed search engines of the moment. SO
