已解决。
在启动的时候，先把这个参数设置成OFF
loose-group_replication_start_on_boot = OFF
在mgr集群设置成功后，再改成ON
loose-group_replication_start_on_boot = ON passio 发表于 2024-3-11 09:14

谢谢反馈，在还没完成MGR初始化前，是不能设置 group_replication_start_on_boot=ON 的，要不然会反复重试启动MGR yejr 发表于 2024-3-11 10:42

参考了，docker镜像里面的配置文件，那里面是ON passio 发表于 2024-3-12 17:01

GreatSQL Docker参考的配置文件是这份 https://gitee.com/GreatSQL/GreatSQL-Docker/blob/master/GreatSQL/my.cnf
其中的 group_replication_start_on_boot 做成了可替换变量：
loose-group_replication_start_on_boot = START_MGR
只有当您在初始化时指定 -e MYSQL_INIT_MGR=1 才会设置为 ON，否则是 OFF，详见处理逻辑 https://gitee.com/GreatSQL/GreatSQL-Docker/blob/master/GreatSQL/greatsql-init.sh#L322
