实战之elasticsearch集群及filebeat server和logstash server
环境
elasticsearch集群节点环境为172.16.100.120:9200，172.16.100.121:9200，172.16.100.122:9200
logstash server服务端为172.16.100.121
filebeat server服务端为172.16.100.121
httpd服务产生日志信息 172.16.100.121
redis服务端172.16.253.181
kibana服务端172.16.253.181
tomcat server端172.16.253.145
网络拓扑图
