將nginx日志通過filebeat收集后傳入logstash，經過logstash處理后寫入elasticsearch。filebeat只負責收集工作，logstash完成日志的格式化，數據的替換，拆分 ，以及將日志寫入elasticsearch后的索引的創建。
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、安裝配置filebeat，啟用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
啟用nginx模塊
./filebeat modules enable nginx
查看模塊
創建配置文件
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"]
啟動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
創建一個nginx日志的pipline文件
cd /usr/local/logstash
logstash內置的模板目錄
vendor/bundle/jruby/2.3.0/gems/logstash-patterns-core-4.1.2/patterns
編輯 grok-patterns 添加一個支持多ip的正則
FORWORD (?:%{IPV4}[,]?[ ]?)+|%{WORD}

創建logstash pipline配置文件
