如何在nginx中使用elasticsearch导入日志

如何在nginx中使用elasticsearch导入日志？相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。

1、配置nginx日志格式

log_format main    '$remote_addr $http_x_forwarded_for [$time_local] $server_name $request '             '$status $body_bytes_sent $http_referer '             '"$http_user_agent" '            '"$connection" '            '"$http_cookie" '            '$request_time '            '$upstream_response_time';

2、安装配置filebeat，启用nginx module

tar -zxvf filebeat-6.2.4-linux-x86_64.tar.gz -C /usr/localcd /usr/local;ln -s filebeat-6.2.4-linux-x86_64 filebeatcd /usr/local/filebeat

启用nginx模块

./filebeat modules enable nginx

查看模块

./filebeat modules list

创建配置文件

vim /usr/local/filebeat/blog_module_logstash.ymlfilebeat.modules:- module: nginx access:  enabled: true  var.paths: ["/home/weblog/blog.cnfol.com_access.log"] #error: # enabled: true # var.paths: ["/home/weblogerr/blog.cnfol.com_error.log"]output.logstash: hosts: ["192.168.15.91:5044"]

启动filebeat

./filebeat -c blog_module_logstash.yml -e

3、配置logstash

tar -zxvf logstash-6.2.4.tar.gz /usr/localcd /usr/local;ln -s logstash-6.2.4 logstash创建一个nginx日志的pipline文件cd /usr/local/logstash

logstash内置的模板目录

vendor/bundle/jruby/2.3.0/gems/logstash-patterns-core-4.1.2/patterns

编辑 grok-patterns 添加一个支持多ip的正则

FORWORD (?:%{IPV4}[,]?[ ]?)+|%{WORD}

官方grok

http://grokdebug.herokuapp.com/patterns#

创建logstash pipline配置文件

启动logstash

nohup bin/logstash -f test_pipline2.conf &
