目标架构

准备工作

参考以下文章安装好ELK与Redis

ELK Stack (1) —— ELK + Redis安装

以CAS系列中的使用的Nginx负载均衡器为例

CAS (1) —— Mac下配置CAS到Tomcat（服务端）

CAS (5) —— Nginx代理模式下浏览器访问CAS服务器配置详解

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}"
        }
}
