#修改配置文件的日志格式:
vim /etc/nginx/nginx.conf

Logstash收集Nginx访问日志

查看nginx日志

Logstash收集Nginx访问日志

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"{

 #添加--configtest参数检查配置语法是否有误!!!
[root@elk-node1 ~]# /opt/logstash/bin/logstash -f /etc/logstash/conf.d/elk_log.conf --configtest
Configuration OK
#把之前后台运行的进程kill掉重启:
[root@elk-node1 ~]# ps aux|grep elk
