问题背景
创建本地复制表时ENGINE = ReplicatedMergeTree('/clickhouse/default/tables/ontime_local/{shard_name}', '{replica}', FlightDate, (Year, FlightDate), 8192);
使用大括号表示会从配置文件中获取宏定义的变量，若未添加该标签会报错
报错信息
DB::Exception: No macro 'shard_name' in config while processing substitutions in '/clickhouse/default/tables/ontime_local/{shard_name}' at '41' or macro is not supported here
添加配置
分别在每个节点服务器的文件/etc/clickhouse-server/metrika.xml或者/etc/clickhouse-server/config.xml中添加
<macros>
<shard_name>01</shard_name>
<replica>clickhouse01</replica>
</macros>
<macros>
<shard_name>01</shard_name>
<replica>clickhouse02</replica>
</macros>
以此类推，每台机器保证replica值不同
此时创建表，即可在集群所有节点上同步创建本地表
参考建表语句
