2020-10-10 架构师第15周作业

架构班的小伙伴作业看这里哦：（学习杰哥视频的作业第29-30天）

1、使用filebeta收集nginx访问日志，并通过geoip展示ip归属地

（一）测试的环境

agentd:192.168.7.22

ES：192.168.7.23

kibana：192.168.7.23

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} - - \[%{HTTPDATE:time_local}\] \"%{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 => ["192.168.7.23:9200"]

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:

4,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://192.168.7.23:9200/]}}[2017-06-20T22:55:23,805][INFO ][logstash.outputs.elasticsearch] Running health check to see if an Elasticsearch connection is working {:healthcheck_url=>http://192.168.7.23:9200/, :path=>"/"}[2017-06-20T22:55:23,901][WARN ][logstash.outputs.elasticsearch] Restored connection to ES instance {:url=>#<URI::HTTP:0x4e54594d URL:http://192.168.7.23:9200/>}[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=>[#<URI::Generic:0x1e098115 URL://192.168.7.23:9200>]}[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/cli

root 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 [02:53:00.081] [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)

2、配置nginx虚拟主机，实现域名访问kibana。

由于kibana界面默认没有安全认证界面，为了保证安全，通过nginx进行代理并设置访问认证。

2.1 配置kibana

[root@linux-elk1 ~]# vim /etc/kibana/kibana.yml

server.host: "127.0.0.1" #将监听地址更改为127.0.0.1

[root@linux-elk1 ~]# systemctl restart kibana

[root@linux-elk1 ~]# netstat -nlutp |grep 5601

tcp 0 0 127.0.0.1:5601 0.0.0.0:* LISTEN 72068/node

2.2 部署nginx

1）安装nginx

[root@linux-elk1 ~]# yum -y install nginx httpd-tools

2）配置nginx

[root@linux-elk1 ~]# vim /etc/nginx/conf.d/kibana.conf

upstream kibana_server {

server 127.0.0.1:5601 weight=1 max_fails=3 fail_timeout=60;

}

server {

listen 80;

server_name www.kibana.com;

auth_basic "Restricted Access";

auth_basic_user_file /etc/nginx/conf.d/htpasswd.users;

location / {

proxy_pass http://kibana_server;

proxy_http_version 1.1;

proxy_set_header Upgrade $http_upgrade;

proxy_set_header Connection 'upgrade';

proxy_set_header Host $host;

proxy_cache_bypass $http_upgrade;

}

[root@linux-elk1 ~]# htpasswd -bc /etc/nginx/conf.d/htpasswd.users admin 123456

Adding password for user admin

[root@linux-elk1 ~]# cat /etc/nginx/conf.d/htpasswd.users

admin:$apr1$ro5tQZp9$grhByziZtm3ZpZCsSFzsQ1

[root@linux-elk1 ~]# systemctl start nginx

3）windows上添加hosts, 路径C:\Windows\System32\drivers\etc\hosts

192.168.7.101 www.kibana.com

4）测试验证
