单机模式部署可以直接从配置上加一台master 去改成双master集群方式部署吗

[hypnoszhang]

发现后起来的master 内置的etcd集群id不一致 导致无法启动。尝试了用etcdctl方式增加peer 但是 增加上去的另外一台master处于unstarted 状态 而且下次启动master会导致etcd无法正常启动

最好是3台。v3.4.0及之后版本支持新加节点，添加新节点之后，修改master的配置cluster_state="existing" 重启。不过不建议这么做，还是最好一开始就使用3台。

请问用两台机器部署的话 有什么要注意的吗。 目前是两台机器都部署了 master 、ps 、router 启动的时候报错 etcd 集群信息不一致

master的配置是和官网文档的配置一致的

两台机器也是保障不了高可用的，坏了一台就无法写了。新加入的节点cluster_state="existing"，不然就是新创建集群，跟之前的节点不在一个集群里
