Logstash收集Nginx访问日志
 
安装nginx
#直接yum安装:
[root@elk-node1 ~]# yum install nginx  -y
ASP站长网官方文档:http://nginx.org/en/docs/http/ngx_http_log_module.html#log_format
#修改配置文件的日志格式:
vim /etc/nginx/nginx.conf
#在http模块中添加

查看nginx日志
 
 
 
编写logstash
#添加nginx日志格式到之前logstash的elk-log.yml
[root@elk-node1 ~]# cat /etc/logstash/conf.d/elk_log.conf
input {
    file {
      path => "/var/log/messages"
      type => "system"
      start_position => "beginning"
    }
    file {
      path => "/var/log/elasticsearch/hejianlai.log"
      type => "es-error"
      start_position => "beginning"
      codec => multiline {
          pattern => "^\["
          negate => true
          what => "previous"
        }
    }
      file {
      path => "/var/log/nginx/access_json.log"
      codec => json
      start_position => "beginning"
      type => "nginx-log"
    }
}
output {
   
    if [type] == "system"{
        elasticsearch {
          hosts => ["192.168.247.135:9200"]
          index => "systemlog-%{+YYYY.MM.dd}"
        }
    }
 
    if [type] == "es-error"{
        elasticsearch {
          hosts => ["192.168.247.135:9200"]
          index => "es-error-%{+YYYY.MM.dd}"
        }
    }
      if [type] == "nginx-log"{
