一台机器安装多个be吗？

我们在同一个机器上安装了一台fe吗，和两个be，每个be的数据放在不同的盘上，日志，安装目录，相关端口也分开了，当我创建表的时候，表的副本数必须是1，如果是2的话，就会报错：

mysql> CREATE TABLE `test` (   `id` varchar(760) NOT NULL COMMENT "",   `name` varchar(64) REPLACE_IF_NOT_NULL NULL COMMENT "",
`age` varchar(64) REPLACE_IF_NOT_NULL NULL COMMENT "" ) ENGINE=OLAP AGGREGATE KEY(`id`) COMMENT "OLAP" DISTRIBUTED BY HASH(`id`) BUCKETS 10 PROPERTIES ( "replication_allocation" = "tag.location.default: 2", "in_memory" = "false", "storage_format" = "V2" );
ERROR 1064 (HY000): errCode = 2, detailMessage = Failed to find enough host with storage medium and tag(HDD/{"location" : "default"}) in all backends. need: 2
mysql> exit

我想问一下：doris支持单节点部署两个be吗？

不可以，端口冲突

show backends;
贴下？
