以nginx错误日志为例，演示日志处理流程

filebeat--logstash--es

filebeat--kafka--logstash--es

#filebeat使用systemd管理/usr/lib/systemd/system/filebeat.service [Unit]Description=FilebeatDocumentation=http://www.elastic.coWants=network-online.targetAfter=network-online.target[Service]ExecStart=/usr/local/filebeat/filebeat -c /usr/local/filebeat/filebeat.ymlRestart=always[Install]WantedBy=multi-user.target

#启动nginx容器，映射日志目录docker run -d --name=nginx --net=host -v /tmp/nginx_log:/var/log/nginx nginx

#nginx错误日志：

2019/09/21 17:00:08 [error] 7#7: *9 open() "/usr/share/nginx/html/api" failed (2: No such file or directory), client: 192.168.3.102, server: localhost, request: "GET /api HTTP/1.1", host: "192.168.3.100"
