一、介绍
总共4台机器，分别为
192.168.1.99
192.168.1.100
192.168.1.210
192.168.1.211
服务所在机器为：
redis：192.168.1.211
logstash: 192.168.210 192.168.1.211
elasticsearch: 分别布置在四台（211不为主、不存储数据）
kibana：192.168.1.211
nginx：192.168.1.211
二、elk集群架构图
三、为每一个软件或集群创建一个单独的角色。
cd /etc/ansible
mkdir -pv elk/roles/{jdk,redis,logstash,es,es_head,kibana,nginx}/{tasks,files,templates,meta,handlers,vars}
四、配置hosts
在/etc/ansible/hosts添加如下内容：
[jdk_servers] 192.168.1.99 192.168.1.100 192.168.1.210 192.168.1.211 [redis_servers] 192.168.1.211 [es_servers] 192.168.1.99 node_name=node-99 node_master=true node_data=true network_host=192.168.1.99 192.168.1.100 node_name=node-100 node_master=true node_data=true network_host=192.168.1.100 192.168.1.210 node_name=node-210 node_master=true node_data=true network_host=192.168.1.210 192.168.1.211 node_name=node-211 node_master=true node_data=true network_host=192.168.1.211 [es_plugin_head] 192.168.1.211 [logstash_servers] 192.168.1.210 192.168.1.211 [kibana_servers] 192.168.1.211 [nginx_servers] 192.168.1.211
PS：es_servers组里面，后面定义了变量，因为es配置文件中，会根据服务器的不同，对应的配置也不同，在这里定义，可以直接在tasks里面去引用
