ELK收集nginx日志并用高德地图展示出IP

（一）测试的环境

agentd:192.168.180.22

ES：192.168.180.23

kibana：192.168.180.23

采用的拓扑：logstash -->ES-->kibana

（二）实施步骤:

（1）logstsh具体配置：

1，配置nginx日志格式，采用log_format格式:

log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '                      '$status $body_bytes_sent "$http_referer" '                      '"$http_user_agent" "$http_x_forwarded_for"';

2,在logstash服务器下载IP地址归类查询库

[root@localhost config]# cd /usr/local/logstash/config/[root@localhost config]#  wget http://geolite.maxmind.com/download/geoip/database/GeoLite2-City.mmdb.gz

3,配置logstash客户端

[root@localhost config]# vim /usr/local/logstash/config/nginx-access.conf input {        file {                path => "/opt/access.log"                type => "nginx"                start_position => "beginning"              }            }filter {          grok {                match => { "message" => "%{IPORHOST:remote_addr} - - \[%{HTTPDATE:time_local}\] \"%{WORD:method} %{URIPATHPARAM:request} HTTP/%{NUMBER:httpversion}\" %{INT:status} %{INT:body_bytes_sent} %{QS:http_referer} %{QS:http_user_agent}"                                }                     } geoip {     source => "remote_addr"     target => "geoip"     database => "/usr/local/logstash/config/GeoLite2-City.mmdb"     add_field => ["[geoip][coordinates]","%{[geoip][longitude]}"]     add_field => ["[geoip][coordinates]","%{[geoip][latitude]}"]                }   }   output {                elasticsearch {                        hosts => ["192.168.180.23:9200"]                        manage_template => true                                                             index => "logstash-map-%{+YYYY-MM}"                                                   }                                                                                }

备注：

• geoip: IP查询插件

• source: 需要通过geoip插件处理的field，一般为ip，这里因为通过控制台手动输入的是ip所以直接填message，生成环境中如果查询nginx访问用户，需先将客户端ip过滤出来，然后这里填remote_addr即可

• target: 解析后的Geoip地址数据，应该存放在哪一个字段中，默认是geoip这个字段

• database: 指定下载的数据库文件

• add_field: 这里两行是添加经纬度，地图中地区显示是根据经纬度来识

。如果启动正常的话，可以在kibana看到geoip相关的字段，如下图:

3,启动logstash客户端并加载刚才的配置文件。

[root@localhost config]# /usr/local/logstash/bin/logstash -f nginx-access.conf  Sending Logstash's logs to /usr/local/logstash/logs which is now configured via log4j2.properties[2017-06-20T22:55:23,801][INFO ][logstash.outputs.elasticsearch] Elasticsearch pool URLs updated {:changes=>{:removed=>[], :added=>[http://192.168.180.23:9200/]}}[2017-06-20T22:55:23,805][INFO ][logstash.outputs.elasticsearch] Running health check to see if an Elasticsearch connection is working {:healthcheck_url=>http://192.168.180.23:9200/, :path=>"/"}[2017-06-20T22:55:23,901][WARN ][logstash.outputs.elasticsearch] Restored connection to ES instance {:url=>#}[2017-06-20T22:55:23,909][INFO ][logstash.outputs.elasticsearch] Using mapping template from {:path=>nil}[2017-06-20T22:55:23,947][INFO ][logstash.outputs.elasticsearch] Attempting to install template {:manage_template=>{"template"=>"logstash-*", "version"=>50001, "settings"=>{"index.refresh_interval"=>"5s"}, "mappings"=>{"_default_"=>{"_all"=>{"enabled"=>true, "norms"=>false}, "dynamic_templates"=>[{"message_field"=>{"path_match"=>"message", "match_mapping_type"=>"string", "mapping"=>{"type"=>"text", "norms"=>false}}}, {"string_fields"=>{"match"=>"*", "match_mapping_type"=>"string", "mapping"=>{"type"=>"text", "norms"=>false, "fields"=>{"keyword"=>{"type"=>"keyword"}}}}}], "properties"=>{"@timestamp"=>{"type"=>"date", "include_in_all"=>false}, "@version"=>{"type"=>"keyword", "include_in_all"=>false}, "geoip"=>{"dynamic"=>true, "properties"=>{"ip"=>{"type"=>"ip"}, "location"=>{"type"=>"geo_point"}, "latitude"=>{"type"=>"half_float"}, "longitude"=>{"type"=>"half_float"}}}}}}}}[2017-06-20T22:55:23,955][INFO ][logstash.outputs.elasticsearch] New Elasticsearch output {:class=>"LogStash::Outputs::ElasticSearch", :hosts=>[#]}[2017-06-20T22:55:24,065][INFO ][logstash.filters.geoip   ] Using geoip database {:path=>"/usr/local/logstash/config/GeoLite2-City.mmdb"}[2017-06-20T22:55:24,094][INFO ][logstash.pipeline        ] Starting pipeline {"id"=>"main", "pipeline.workers"=>4, "pipeline.batch.size"=>125, "pipeline.batch.delay"=>5, "pipeline.max_inflight"=>500}[2017-06-20T22:55:24,275][INFO ][logstash.pipeline        ] Pipeline main started[2017-06-20T22:55:24,369][INFO ][logstash.agent           ] Successfully started Logstash API endpoint {:port=>9600}

（2）Kibana配置.

1,编辑修改kibana的配置文件kibana.yml在最后添加如下：

# The default locale. This locale can be used in certain circumstances to substitute any missing# translations.#i18n.defaultLocale: "en"tilemap.url: 'http://webrd02.is.autonavi.com/appmaptile?lang=zh_cn&size=1&scale=1&style=7&x={x}&y={y}&z={z}'

2,重启kibana服务。

[root@localhost bin]# /usr/local/kibana/bin/kibana &[1] 10631[root@localhost bin]# ps -ef|grep kibana            root     10631  7795 21 10:52 pts/0    00:00:02 /usr/local/kibana/bin/../node/bin/node --no-warnings /usr/local/kibana/bin/../src/cliroot     10643  7795  0 10:52 pts/0    00:00:00 grep --color=auto kibana[root@localhost bin]#   log   [02:52:59.297] [info][status][plugin:kibana@5.4.0] Status changed from uninitialized to green - Ready  log   [02:52:59.445] [info][status][plugin:elasticsearch@5.4.0] Status changed from uninitialized to yellow - Waiting for Elasticsearch  log   [02:52:59.482] [info][status][plugin:console@5.4.0] Status changed from uninitialized to green - Ready  log   [02:52:59.512] [info][status][plugin:elasticsearch@5.4.0] Status changed from yellow to green - Kibana index ready  log   [02:52:59.513] [info][status][plugin:metrics@5.4.0] Status changed from uninitialized to green - Ready  log   [02:53:00.075] [info][status][plugin:timelion@5.4.0] Status changed from uninitialized to green - Ready  log   [02:53:00.080] [info][listening] Server running at http://192.168.180.23:5601  log   [02:53:00.081] [info][status][ui settings] Status changed from uninitialized to green - Ready

3，创建nginx的访问索引lostash-map*。具体步骤如下：ip:5601--->Management--Index Patterns--->+--->在Index name or pattern中添加logstash-map*--->create。具体如下图：

4,创建Visualize。具体步骤如下：Visalize--->+--->Maps(Tile Maps)

已上就是简单的步骤。
