部署机器:
服务端：
dev-server X.X.X.X ( logstash-1.5.4，elasticsearch-1.7.1，kibana-4.1.1 )
客户端:
dev-client X.X.X.X (logstash-forwarder-0.4.0-1)
需求:将客户端访问日志(nginx log)在ELK中展示。
安装ELK：
服务端:
设置FQDN(创建SSL证书的时候需要配置FQDN)：
[root@dev-client ~]# hostname dev-client [root@dev-client ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 X.X.X.X elk.test.com elk
