日志分析平台ELK之前端展示kibana

　　之前的博客一直在聊ELK集群中的存储、日志收集相关的组件的配置，但通常我们给用户使用不应该是一个黑黑的shell界面，通过接口去查询搜索；今天我们来聊ELK中的前端可视化组件kibana；kibana主要作用是用来展示、搜索、查看、分析、整合elasticsearch中存储的日志的一个web用户界面；使得让用户使用ELK更加直观；

　　配置kibana连接es

　　提示：server.port用于指定kibana监听的端口，server.host用于指定kibana监听的地址，0.0.0.0表示监听本机所有可用地址；server.name是指定本机的主机名，elasticsearch.hosts用于指定es集群主机地址；配置好以上四项就可以直接启动kibana了；

　　启动kibana
