定义安装配置文件
参考用例：
cat ba-redis-examples.conf
####服务器相关配置######
#实例类型
instance_type=ecs.n4.small
#镜像id

#实例付费方式,PrePaid：包年包月,PostPaid：按量付费

# 主机名
instance_name=ba-redis-examples
####redis相关配置######
# 集群主机
cluster_hosts=
# 集群端口
port=6379
#集群密码
pass=
-
instance_name和文件名保证一致，表示集群名称
-
根据购买8G或者16G机器规格，修改服务器相关配置
-
redis相关配置保持默认值，集群在创建、节点新增、删除会修改对应redis相关配置
-
配置文件最好保存到文件系统中，供后续节点新增或删除时使用
集群创建
