phabricator 报如下错误
Replicating Master
Database host “[数据库地址]” is configured as a master, but is replicating another host. This is dangerous and can mangle or destroy data. Only replicas should be replicating. Stop replication on the host or reconfigure Phabricator.

然后发现原因是RDS自动做了主从备份，据说还是双向，而且无法关闭。
只能从程序下手了，搜索代码发现在

switch ($ref->getReplicaStatus()) {
      case PhabricatorDatabaseRef::REPLICATION_MASTER_REPLICA:
     break;<----新增的
        $message = pht(
          'Database host "%s" is configured as a master, but is replicating '.
          'another host. This is dangerous and can mangle or destroy data. '.
          'Only replicas should be replicating. Stop replication on the '.
          'host or reconfigure Phabricator.',
 $ref->getRefKey());

这个文件的174行左右判断验证了

然后我在case后直接写了个break，绕过了验证，反正是可以用了
