CentOS与Filebeat集成步骤如下：
sudo yum install epel-release，然后sudo yum install filebeat；也可手动下载RPM包安装，如wget https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-7.x.x-linux-x86_64.rpm，再执行sudo rpm -ivh filebeat-7.x.x-linux-x86_64.rpm。/etc/filebeat/filebeat.yml文件，设置要监控的日志路径filebeat.inputs和Elasticsearch的输出地址output.elasticsearch等参数，如filebeat.inputs: - type: log enabled: true paths: - /var/log/*.log，output.elasticsearch: hosts: ["localhost:9200"]。sudo systemctl start filebeat，并设置为开机自启动sudo systemctl enable filebeat。sudo tail -f /var/log/filebeat/filebeat.log，或检查Elasticsearch集群状态curl -X GET "localhost:9200/_cluster/health?pretty"来验证是否集成成功。
