cluckhouse 版本22.2.2.1.
按照网上的教程配置/etc/clickhouse/config.xml后查询system.clusters就是没有对应的信息。
检查config.xml里面是不是有多个remove_servers标签！！！
一直没有看到原来的config.xml文件中间还有一个<remove_servers>标签...ffffk

注： 文件保存后后ClickHouse会自动加载配置文件，不需要重启
下面是3分片1副本配置,单机zookeeper

<clickhouse>
  ...
  <include_from>/etc/clickhouse-server/metrika.xml</include_from>
  <remote_servers incl="clickhouse_remote_servers" />
  <zookeeper incl="zookeeper-servers" optional="true" />
  <macros incl="macros" optional="true" />
  <compression incl="clickhouse_compression" optional="true" />
</clickhouse>

然后配置/etc/clickhouse/metrika.xml

<yandex>
    <clickhouse_remote_servers>
        <demo_3shards_1replicas>
            <shard>
                <internal_replication>true</internal_replication>
                <replica>
                    <host>node1</host>
                    <port>9000</port>
                </replica>
            </shard>
            <shard>
                <internal_replication>true</internal_replication>
                <replica>
                    <host>node2</host>
                    <port>9000</port>
                </replica>
            </shard>
            <shard>
                <internal_replication>true</internal_replication>
                <replica>
                    <host>node3</host>
                    <port>9000</port>
                </replica>
            </shard>
        </demo_3shards_1replicas>
    </clickhouse_remote_servers>
    <zookeeper-servers>
        <node index="1">
            <host>node1</host>
            <port>2181</port>
        </node>
    </zookeeper-servers>
    <macros>
        <replica>node2</replica>
    </macros>
    <networks>
        <ip>::/0</ip>
    </networks>
    <clickhouse_compression>
        <case>
            <min_part_size>10000000000</min_part_size>
            <min_part_size_ratio>0.01</min_part_size_ratio>
            <method>lz4</method>
        </case>
    </clickhouse_compression>
</yandex>

或者把配置文件放在/etc/clickhouse/conf.d/下也可以，会和config.xml里面配置合并
