zookeeper dubbo 集群

zookeeper 集群时
dubbo配置

provider 端
dubbo.registry.address=zookeeper://127.0.0.1:21811?backup=127.0.0.1:21812,127.0.0.1:21813

client端
一个注册中心
dubbo.registry.address=zookeeper://127.0.0.1:21811?backup=127.0.0.1:21812,127.0.0.1:21813

多个注册中心
dubbo.registry.address=zookeeper://127.0.0.1:2181|zookeeper://127.0.0.1:21811?backup=127.0.0.1:21812,127.0.0.1:21813

建议node个数为奇数个 当zookeeper存活个数大于1/2时（不含等于） 整个集群才有用
如
总数为4个 宕机2个 整个集群无效
