ELK 7.6分析 Nginx 日志 并启用x-pack权限认证

Posted 2020-11-27

安装之前先附上Kibana配置效果图

nginx 服务器日志的log_format格式如下：

log_format main_cookie ‘$remote_addr	$host	$time_local	$status	$request_method	$uri	$query_string	$body_bytes_sent	$http_referer	$http_user_ag
ent	$bytes_sent	$request_time	$upstream_response_time	$aoji_uuid	$aoji_session_uuid‘; ```

软件包如下：

## 1、elasticsearch 7.6 安装及配置
elasticsearch-7.6.0-linux-x86_64.tar.gz 解压到 /data/ 目录

tar xf elasticsearch-7.6.0-linux-x86_64.tar.gz && mv elasticsearch-7.6.0 /data/

配置文件所在目录：/data/elasticsearch-7.6.0/config 修改配置文件elasticsearch.yml

node.name: es-1
network.host: 172.31.0.14
http.port: 9200
xpack.security.enabled: true
discovery.type: single-node ```

1.1 运行ES

su - admin
/data/elasticsearch-7.6.0/bin/elasticsearch -d

1.2 设置密码

在elasticsearch-7.6.0/bin/目录下运行elasticsearch-setup-passwords设置密码（账号默认为elastic）：
./elasticsearch-setup-passwords interactive
它会不止是设置elasticsearch，其他的kibana、logstash也会一起设置了，密码最好全设置同一个 

2、logstash 7.6 安装及配置

tar xf logstash-7.6.0.tar.gz && mv logstash-7.6.0 /data/logstash
修改配置文件logstash.yml，内容如下：
node.name: node-1
xpack.monitoring.enabled: true
xpack.monitoring.elasticsearch.username: logstash_system
xpack.monitoring.elasticsearch.password: 123456
xpack.monitoring.elasticsearch.hosts: ["http://172.31.0.14:9200"]
在confg目录下创建nginx_access.conf, 内容如下：
input {
    file {
        path => [ "/data/weblog/yourdoamins/access.log" ]
        start_position => "beginning"
        ignore_older => 0
    }
}

filter {
    grok {
        match => { "message" => "%{IPV4:client_ip}	%{HOSTNAME:domain}	%{HTTPDATE:timestamp}	%{INT:status}	(%{WORD:request_method}|-)	(%{URIPATH:ur
i}|-|)	(?:%{DATA:query_string}|-)	(?:%{BASE10NUM:body_bytes_sent}|-)	%{DATA:referrer}	%{DATA:agent}	%{INT:bytes_sent}	%{BASE16FLOAT:request_time}
	%{BASE16FLOAT:upstream_response_time}" }

    }
    geoip {
      source => "client_ip"
      target => "geoip"
      database => "/data/logstash/GeoLite2-City.mmdb"
      add_field => [ "[geoip][coordinates]", "%{[geoip][longitude]}" ]
      add_field => [ "[geoip][coordinates]", "%{[geoip][latitude]}" ]
    }

    mutate {
      convert => [ "[geoip][coordinates]", "float" ]
      convert => [ "response","integer" ]
      convert => [ "bytes","integer" ]
      replace => { "type" => "nginx_access" }
      remove_field => "message"
    }

}
output {
    elasticsearch {
        hosts => ["172.31.0.14:9200"]
        index => "logstash-nginx-access-%{+YYYY.MM.dd}"
        user => "elastic"
        password => "123456"
    }
    stdout {codec => rubydebug}
}

相关配置文件解释，请自行查看官方文档或Google

2.1 配置IP库

然后就是logstash中配置的GeoIP的数据库解析ip了，这里是用了开源的ip数据源，用来分析客户端的ip归属地。官网在这里:MAXMIND

tar xf GeoLite2-City_20200218.tar.gz
cd GeoLite2-City_20200218 && mv GeoLite2-City.mmdb /data/logstash
测试下logstash 的配置文件，使用它自带的命令去测试，如下：
#./bin/logstash -t -f config/nginx_access.conf
Configuration OK

2.2 启动logstash

cd /data/logstash/
nohup /data/logstash/bin/logstash -f config/nginx_access.conf &

3、Kibanan 7.6 安装及配置

tar xf kibana-7.6.0-linux-x86_64.tar.gz && mv kibana-7.6.0 /data/

修改配置文件kibana.yml，内容如下：

server.port: 5601
server.host: "172.31.0.14"
elasticsearch.hosts: ["http://172.31.0.14:9200"]
elasticsearch.username: "elastic"
elasticsearch.password: "123456"
i18n.locale: "zh-CN"

3.1启动Kibana

nohup /data/kibana-7.6.0/bin/kibana & 

3.2配置Nginx代理

upstream yourdomain {
        server 172.31.0.14:5601;
}

server {
    listen 80;
    server_name  yourdomain;
    return 302 https://$server_name$request_uri;
}

server {
listen 443 ssl;
server_name  yourdomain;

ssl_session_timeout  5m;
ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
ssl_prefer_server_ciphers   on;
ssl_certificate /data/ssl/yourdomain.cer;
ssl_certificate_key  /data/ssl/yourdomain.key;
ssl_trusted_certificate /data/ssl/yourdomain.ca.cer;

location / {
        proxy_pass http:// yourdomain;
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_next_upstream http_502 http_504 http_404 error timeout invalid_header;

}

access_log  /data/weblog/yourdomain/access.log  main;
error_log  /data/weblog/yourdomain/error.log;
}

3.3检查站点是否访问正常，可以正常的访问kibana界面

    后续Kibana中添加索引，配置可视化图形都很简单了，官方文档比较全面自行发挥配置即可，
以上就是生产环境配置，由于鄙人水平有限，有什么配置不当得地方请小伙伴们指正纠错，感谢。
