大数据培训ClickHouse分布式集群安装

1 在hadoop103，hadoop104上面执行之前的所有步骤

2 三台机器修改配置文件config.xml

[root@hadoop102 ~]# vim /etc/clickhouse-server/config.xml

<listen_host>::</listen_host>

<!– <listen_host>::1</listen_host> –>

<!– <listen_host>127.0.0.1</listen_host> –>

[root@hadoop103 ~]# vim /etc/clickhouse-server/config.xml

<listen_host>::</listen_host>

<!– <listen_host>::1</listen_host> –>

<!– <listen_host>127.0.0.1</listen_host> –>

[root@hadoop104 ~]# vim /etc/clickhouse-server/config.xml

<listen_host>::</listen_host>

<!– <listen_host>::1</listen_host> –>

<!– <listen_host>127.0.0.1</listen_host> –>

3 在三台机器的etc目录下新建metrika.xml文件

[root@hadoop102 ~]# vim /etc/metrika.xml

添加如下内容：

<yandex>

<clickhouse_remote_servers>

    <perftest_3shards_1replicas>

        <shard>

             <internal_replication>true</internal_replication>

            <replica>

                <host>hadoop102</host>

                <port>9000</port>

            </replica>

        </shard>

注意：上面标红的地方需要根据机器不同去修改

4 三台机器启动ClickServer

首先在三台机器开启Zookeeper

前台启动：

[root@hadoop102 software]# clickhouse-server –config-file=/etc/clickhouse-server/config.xml

后台启动：

[root@hadoop102 software]# nohup clickhouse-server –config-file=/etc/clickhouse-server/config.xml  >null 2>&1 &
