我是三台主机的, iptables, selinux ,ipv6全关, 第一个节点成功启动了并且加入group, 但是第二个节点死活加入不了group, 网上目前有几篇操作手册, 跟官方都差不多, 应该有人成功过, 不知道自己哪里做的不对
安装官方第二个节点, 在安装完插件后, 只需启动group replication即可
START GROUP_REPLICATION;第二个节点错误日志如下:

官网文档没有提到的是, 成功启动第一个node后, 在启动其他node的时候需要一个命令
set global group_replication_allow_local_disjoint_gtids_join=ON;为什么要执行, 可以看日志里面有提示, 注意不要光看ERROR的, 这个参数在一个NOTE级别的日志里面说了, 我觉得有点不妥, 起码是WARN的吧

我也遇到了同样的问题，跨机器就是玩不转，所有的参数都做了尝试，搞不懂为何修改了IP，就不能够成功加入了，可能是哪里没有设置到位，我是新司机不懂路子，期待老司机带带。。。。
