我使用以下链接将 mysql master 配置为 master 组复制https://www.digitalocean.com/community/tutorials/how-to-configure-mysql-group-replication-on-ubuntu-16-04

我使用上面的链接连接了两个不同的服务器。第一个服务器已连接。但是第二台服务器没有连接，它给出了错误

我使用 mysql> START GROUP_REPLICATION; 此命令配置第二个服务器。但我收到以下错误日志

会不会是 SELinux？

您可以尝试通过编辑禁用 SELinux：/etc/selinux/config 并将以下行更改：SELINUX=enforcing 为：SELINUX=disabled

重新启动系统并重试。
