Mysql组复制无法添加实例

【中文标题】Mysql组复制无法添加实例

【英文标题】：Mysql group replication can't add instance

【发布时间】：2018-08-31 14:20:49

【问题描述】：

22.22.22.22 上的配置文件：

...

loose-group_replication_group_name="aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa"
loose-group_replication_start_on_boot=off
loose-group_replication_local_address= "127.0.0.1:33061"
loose-group_replication_group_seeds= "127.0.0.1:33061,33.33.33.33:33061"
loose-group_replication_bootstrap_group=off

我按照文档说的做了：

SET SQL_LOG_BIN=0;
CREATE USER rpl_user@'%' IDENTIFIED BY 'password';
GRANT REPLICATION SLAVE ON *.* TO rpl_user@'%';
FLUSH PRIVILEGES
SET SQL_LOG_BIN=1
CHANGE MASTER TO MASTER_USER='rpl_user', MASTER_PASSWORD='password' FOR CHANNEL 'group_replication_recovery';

INSTALL PLUGIN group_replication SONAME 'group_replication.so';

SET GLOBAL group_replication_bootstrap_group=ON;
START GROUP_REPLICATION;
SET GLOBAL group_replication_bootstrap_group=OFF;

到目前为止一切正常...

我在 33.33.33.33 上有一个配置文件：

...

loose-group_replication_group_name="aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa"
loose-group_replication_start_on_boot=off
loose-group_replication_local_address= "127.0.0.1:33061"
loose-group_replication_group_seeds= "22.22.22.22:33061,127.0.0.1:33061"
loose-group_replication_bootstrap_group=off

我也关注文档：

SET SQL_LOG_BIN=0;
CREATE USER rpl_user@'%' IDENTIFIED BY 'password';
GRANT REPLICATION SLAVE ON *.* TO rpl_user@'%';
SET SQL_LOG_BIN=1;
CHANGE MASTER TO MASTER_USER='rpl_user', MASTER_PASSWORD='password' FOR CHANNEL 'group_replication_recovery';

INSTALL PLUGIN group_replication SONAME 'group_replication.so';

一切都还好..

但是当我进入时

START GROUP_REPLICATION;

在 33.33.33.33 出现错误：

ERROR 3092 (HY000)：服务器未正确配置为组的活动成员。请查看错误日志的更多详细信息。

错误日志：

怎么办？

mysql 版本：8.0.12

【参考方案1】：

您正在将通信地址竞价到本地主机地址：

loose-group_replication_local_address="127.0.0.1:33061"

loose-group_replication_local_address="127.0.0.1:33061"

但是您随后尝试使用公共地址联系成员。 如果要公开联系该成员，则需要绑定到公共地址。

【讨论】：

你好@Pedro - 我也面临同样的问题。如果我与本地绑定，则组复制工作，但其他服务器无法加入该组。如果我提供公共 IP，则组复制不会启动。它失败并出现此错误 - There is no local IP address matching the one configured for the local node 知道该怎么做吗？
