(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:

1
2
3
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

1
2
3
[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} - - \[%{HTTPDATE:time_local}\] \"%{WO
RD: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。

(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。

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)
