ELK是Elasticsearch、Logstash、Kibana的简称，这三者是核心套件，但并非全部。
Elasticsearch是实时全文搜索和分析引擎，提供搜集、分析、存储数据三大功能；是一套开放REST和JAVA API等结构提供高效搜索功能，可扩展的分布式系统。它构建于Apache Lucene搜索引擎库之上。
Logstash是一个用来搜集、分析、过滤日志的工具。它支持几乎任何类型的日志，包括系统日志、错误日志和自定义应用程序日志。它可以从许多来源接收日志，这些来源包括 syslog、消息传递（例如 RabbitMQ）和JMX，它能够以多种方式输出数据，包括电子邮件、websockets和Elasticsearch。
Kibana是一个基于Web的图形界面，用于搜索、分析和可视化存储在 Elasticsearch指标中的日志数据。它利用Elasticsearch的REST接口来检索数据，不仅允许用户创建他们自己的数据的定制仪表板视图，还允许他们以特殊的方式查询和过滤数据
Redis REmote DIctionary Server(Redis) 是一个由Salvatore Sanfilippo写的key-value存储系统。
Redis是一个开源的使用ANSI C语言编写、遵守BSD协议、支持网络、可基于内存亦可持久化的日志型、Key-Value数据库，并提供多种语言的API。
它通常被称为数据结构服务器，因为值（value）可以是 字符串(String), 哈希(Hash), 列表(list), 集合(sets) 和 有序集合(sorted sets)等类型，在ELK套件中作为数据临时存储的作用。
Filebeat是本地文件的日志数据采集器。 作为服务器上的代理安装，Filebeat监视日志目录或特定日志文件，tail file，并将它们转发给Elasticsearch或Logstash进行索引、kafka 等。
2.本次使用框架
3.安装
3.1 filebeat安装
安装包：
filebeat-5.6.0-linux-x86_64.tar.gz
tar -xzvf filebeat-5.6.0-linux-x86_64.tar.gz mv filebeat-5.6.0-linux-x86_64 filebeat cd filebeat 编辑配置文件--> filebeat.yml 添加收集日志文件，导入redis ##input #------------------------------ Log prospector -------------------------------- - input_type: log # Paths that should be crawled and fetched. Glob based paths. # To fetch all ".log" files from a specific level of subdirectories # /var/log/*/*.log can be used. # For each file found under this path, a harvester is started. # Make sure not file is defined twice as this can lead to unexpected behaviour. paths: - /var/log/*.log #- c:programdataelasticsearchlogs* ##output #------------------------------- Redis output ---------------------------------- output.redis: # Boolean flag to enable or disable the output module. enabled: true # The list of Redis servers to connect to. If load balancing is enabled, the # events are distributed to the servers in the list. If one server becomes # unreachable, the events are distributed to the reachable servers only. hosts: ["192.168.1.110"] # The Redis port to use if hosts does not contain a port number. The default # is 6379. port: 6379 # The name of the Redis list or channel the events are published to. The # default is filebeat. key: filebeat # The password to authenticate with. The default is no authentication. password: xian123 # The Redis database number where the events are published. The default is 0. db: 0 # The Redis data type to use for publishing events. If the data type is list, # the Redis RPUSH command is used. If the data type is channel, the Redis # PUBLISH command is used. The default value is list. datatype: list # The number of workers to use for each host configured to publish events to # Redis. Use this setting along with the loadbalance option. For example, if # you have 2 hosts and 3 workers, in total 6 workers are started (3 for each # host). worker: 1 # If set to true and multiple hosts or workers are configured, the output # plugin load balances published events onto all Redis hosts. If set to false, # the output plugin sends all events to only one host (determined at random) # and will switch to another host if the currently selected one becomes # unreachable. The default value is true. loadbalance: true # The Redis connection timeout in seconds. The default is 5 seconds. timeout: 5s # The number of times to retry publishing an event after a publishing failure. # After the specified number of retries, the events are typically dropped. # Some Beats, such as Filebeat, ignore the max_retries setting and retry until # all events are published. Set max_retries to a value less than 0 to retry # until all events are published. The default is 3. #max_retries: 3
redis安装
安装包：
redis-5.0.4.tar.gz
tar -xzvf redis-5.0.4.tar.gz cd redis-5.0.4 Make && make install Vi redis.conf 设置绑定端口bind ip，密码requirepass “密码” 启动 cd src ./redis-server ../redis.conf & 启动filebeat cd /home/elk/filebeat ./filebeat -e -c filebeat.yml > /dev/null & 查看redis是否有日志
如有数据表示可以收集日志并导入redis，如无数据表示安装配置有问题；
下面是安装elasticsearch，建议内存够大，因为这个组件极耗内存

安装logstash：
tar -xzvf logstash-5.3.1.tar.gz 创建软链接 ln -s /home/elk/logstash-5.3.1 /usr/local/logstash 验证 /usr/local/logstash/bin/logstash -e 'input { stdin { } } output { stdout {} }' 建立配置文件 vi /usr/local/logstash/config/logstash-simple.conf input { stdin { } } output { stdout { codec=> rubydebug } } 使用logstash参数-f读取配置文件进行测试： /usr/local/logstash/bin/logstash -f /usr/local/logstash/config/logstash-simple.conf
创建配置文件获取redis日志的数据： 配置文件如下： vi /usr/local/logstash/config/redis-spring.conf input { redis { port => "6379" host => "192.168.1.110" ###redis服务器 data_type => "list" password => "xian123" type => "log" key => "filebeat" db => "0" } } output { elasticsearch hosts => "192.168.1.100:9200" ## index => "logstash1-%{+YYYY.MM.dd}" } } ~ 通过配置文件启动服务查看效果： /usr/local/logstash/bin/logstash -f /usr/local/logstash/config/redis-spring.conf
