目标架构

准备工作

参考以下文章安装好ELK与Redis

以CAS系列中的使用的Nginx负载均衡器为例

ELK配置

• Nginx

  修改nginx.conf

  log_format logstash '$http_host $server_addr $remote_addr [$time_local] "$request" '              '$request_body $status $body_bytes_sent "$http_referer" "$http_user_agent" '              '$request_time $upstream_response_time';

  

• Elasticsearch

  修改elasticsearch.yml

  cluster.name: logstash_elasticsearch  http.cors.allow-origin: "/.*/"  http.cors.enabled: true

  

• Logstash

  • /logstash/conf/logstash_agent.conf

    input {          file {                  type => "nginx_access"                  path => ["/usr/share/nginx/logs/test.access.log"]          }  }  output {          redis {                  host => "localhost"                  data_type => "list"                  key => "logstash:redis"          }  }

  • /logstash/conf/logstash_indexer.conf

    input {          redis {                  host => "localhost"                  data_type => "list"                  key => "logstash:redis"                  type => "redis-input"          }  }  filter {      grok {          match => [              "message", "%{WORD:http_host} %{URIHOST:api_domain} %{IP:inner_ip} %{IP:lvs_ip} \[%{HTTPDATE:timestamp}\] \"%{WORD:http_verb} %{URIPATH:baseurl}(?:\?%{NOTSPACE:request}|) HTTP/%{NUMBER:http_version}\" (?:-|%{NOTSPACE:request}) %{NUMBER:http_status_code} (?:%{NUMBER:bytes_read}|-) %{QS:referrer} %{QS:agent} %{NUMBER:time_duration:float} (?:%{NUMBER:time_backend_response:float}|-)"          ]      }      kv {          prefix => "request."          field_split => "&"          source => "request"      }      urldecode {          all_fields => true      }      #date {      #    type => "log-date"      #    match => ["timestamp" , "dd/MMM/YYYY:HH:mm:ss Z"]      #}      date {          match => ["logdate" , "dd/MMM/YYYY:HH:mm:ss Z"]      }  }  output {          elasticsearch {                  #embedded => false                  #protocol => "http"                  hosts => "localhost:9200"                  index => "access-%{+YYYY.MM.dd}"          }  }

  注意有些网络示例为旧版本配置，新版本下output的embedded、protocol以及filter的date都有所更新。

• Kibana

  创建Index Pattern: access-*

测试

访问本地Kibana
