我已经创建了3个mongodb示例，下面是mongod.conf [Primary 1，Secondary 1，Secondary 2]

net:
  port: 27017
  bindIp: 0.0.0.0

replication:
  replSetName: Replica1

我已经使用“sudo service mongod start“启动了3个示例，如果我使用mongo -host“ip”-port 27017将主服务器连接到其他2个服务器，它将工作并连接。

第1期：

在我执行rs.initiate（）和rs.conf（）之后，辅助节点1包含在成员中，但当我使用rs.status（）时，却显示stateStr”：“启动”，如果我检查其日志，则表示以下错误：

“消息”：“获取事务表失败”，“属性”：{“错误”：“尚未初始化：尚未配置复制”}}
第2期：

由于问题1，如果我尝试为辅助2使用rs.add（），它不起作用

rs.状态（）响应
