1.安裝Nginx

[root@web01 ~]# yum install -y nginx

2.配置Nginx日誌格式

[root@web01 ~]# vim /etc/nginx/nginx.conf
... ...
http {
    log_format  json  '{"@timestamp":"$time_iso8601",'
                      '"host":"$server_addr",'
                      '"clientip":"$remote_addr",'
                      '"size":$body_bytes_sent,'
                      '"responsetime":$request_time,'
                      '"upstreamtime":"$upstream_response_time",'
                      '"upstreamhost":"$upstream_addr",'
                      '"http_host":"$host",'
                      '"url":"$uri",'
                      '"referer":"$http_referer",'
                      '"agent":"$http_user_agent",'
                      '"status":"$status"}';

    access_log  /var/log/nginx/access.log  json;
... ...
 

3.配置收集Nginx日誌

[root@web01 ~]# vim /etc/logstash/conf.d/nginx_json.conf
input {
  file {
    path => "/var/log/nginx/access.log"
    start_position => "beginning"
  }
}
output {
  elasticsearch {
    hosts => ["10.0.0.51:9200"]
    index => "nginx_json_%{+YYYY-MM-dd}.log"
  }
}
