Logstash + Elasticsearch + kibana+redis+syslog-ng
Elasticsearch is an open source, distributed, restful search engine built on Lucene. Designed for cloud computing, to achieve real-time search, stable, reliable, fast, easy to install and use. Supports the use of JSON for data indexing over HTTP.
Logstash is a platform for application log, event transmission, processing, management, and search. You can

Generally, logs are stored separately on different devices. If you manage dozens of hundreds of servers, you are still using the traditional method of logging on to each server in sequence to view logs. Is this complicated and inefficient. It is imperative to use centralized log management, such as open-source syslog To collect and summarize logs on all servers.

4.1 unzip the installation package:
# tar xf logstash-6.4.2.tar.gz -C /usr/local/
4.2 modify the configuration file/usr/local/logstash-6.4.2/config/logstash. yml as follows:
[[Email protected] logstash-6.4.2] # egrep-V "^ # | ^ $"/usr/local/logstash-6.4.2/config/logstash. yml path. data:/opt/elk/logstash
.
Centralized logging is useful when trying to identify a problem with a server or application because it allows you to search all logs in a single location. It is also useful because it allows you to identify issues across multiple servers by associating their logs within a specific time frame.
You can use Logstash to collect all types of logs, but we limit the scope of this tutorial to Syslog collection. Experimental Purpose

Syslog is an industrial standard protocol that can be used to record device logs. In UNIX systems, routers, switches, and other network devices, System logs record System events at any time. Administrators can view system records to keep abre

important information, it is still using the traditional method, to log on to a machine to view. It seems that the traditional tools and methods have become very clumsy and inefficient. As a result, some smart people put forward a centralized approach to integrating data from different sources into one place.
A complete centralized log system is inseparable from the following key features. Collection-capable of capturing log data from multiple sources-can reliably transfer logs to a central sys
