将nginx日志通过filebeat收集后传入logstash，经过logstash处理后写入elasticsearch。filebeat只负责收集工作，logstash完成日志的格式化，数据的替换，拆分 ，以及将日志写入elasticsearch后的索引的创建。 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/local cd /usr/local;ln -s filebeat-6.2.4-linux-x86_64 filebeat cd /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.yml filebeat.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/local cd /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
