本文从日志解读MGR节点加入过程。

1. 从日志理解（手动）加入新节点过程

新节点加入MGR集群时，通过观察它的日志（设置 log_error_verbosity=3 日志中能记录更多信息，便于跟踪和排查故障），能更好的理解MGR的工作过程及数据同步机制。

下面是（命令行手工操作方式，不是通过MySQL Shell调用）新节点加入时，从Primary节点看到的日志（对时间戳、主机名等做了简单处理）：

17:05:51.157750 [System] [MY-011490] [Repl] Plugin group_replication reported: 'This server was declared online within the replication group.'

根据上面的日志，可知加入新节点的过程（简化后）大致如下：

初始化MGR相关设置。
准备执行view change。
新节点加入成功。
确认donor节点后，进行分布式恢复（本地恢复全局恢复）。
宣告本节点状态为online。

2. 从日志理解（mysql shell调用）加入新节点过程

如果通过MySQL Shell新增一个MGR节点，操作过程简单很多，可以参考这篇文档：4. 利用MySQL Shell安装部署MGR集群 | 深入浅出MGR。这里通过阅读日志来理解利用MySQL Shell加入新节点的逻辑过程：
