Ck（一）安装

一、本次下载安装ck版本19.16.2.2

1、ck下载地址：https : //repo.yandex.ru/clickhouse/rpm/stable/x86_64/

2、注意：此版本需要这三个包，其他版本可能还需要其他包。

clickhouse-client-19.16.2.2-2.noarch.rpm 
clickhouse-common-static-19.16.2.2-2.x86_64.rpm 
clickhouse-server-19.16.2.2-2.noarch.rpm

3、如果是Centos6.x可能会报一个glib版本的错误

1、glibc下载：
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-2.17-55.el6.x86_64.rpm
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-common-2.17-55.el6.x86_64.rpm
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-devel-2.17-55.el6.x86_64.rpm
wget http://copr-be.cloud.fedoraproject.org/results/mosquito/myrepo-el6/epel-6-x86_64/glibc-2.17-55.fc20/glibc-headers-2.17-55.el6.x86_64.rpm
2、执行命令：
sudo rpm -Uvh glibc-2.17-55.el6.x86_64.rpm \
glibc-common-2.17-55.el6.x86_64.rpm \
glibc-devel-2.17-55.el6.x86_64.rpm \
glibc-headers-2.17-55.el6.x86_64.rpm
3、若上诉命令执行报依赖问题则执行：
sudo rpm -Uvh glibc-2.17-55.el6.x86_64.rpm \
glibc-common-2.17-55.el6.x86_64.rpm \
glibc-devel-2.17-55.el6.x86_64.rpm \
glibc-headers-2.17-55.el6.x86_64.rpm\
--force --nodeps

4、rpm -ivh *.rpm 

5、在/etc/clickhouse-server/ 下config.xml添加

<include_from>/etc/clickhouse-server/metrika.xml</include_from>

6、在metrika.xml中内容大致为：zk为单节点，集群时<node index = ""1"">把node对应的index带上

<clickhouse_remote_servers>
         <bip_ck_cluster>
        <shard>
                <internal_replication>true</internal_replication>
                <replica>
                        <default_database>shard1</default_database>
                        <host>node04</host>
                        <port>9000</port>
                        <user>default</user>
                        <password>password</password>
                </replica>
            <replica>
                <default_database>shard1</default_database>
                <host>node05</host>
                <port>9000</port>
                <user>default</user>
                <password>password</password>
            </replica>
        </shard>
    <shard>
        <internal_replication>true</internal_replication>
        <replica>
                <default_database>shard2</default_database>
                <host>node04</host>
                <port>9000</port>
                <user>default</user>
                <password>password</password>
        </replica>
        <replica>
                <default_database>shard2</default_database>
                <host>node05</host>
                <port>9000</port>
                <user>default</user>
                <password>password</password>
        </replica>
    </shard>
    </bip_ck_cluster>
    </clickhouse_remote_servers>
    <!--zookeeper相关配置-->
    <zookeeper-servers>
    <node index="1">
        <host>192.168.231.135</host>
        <port>2181</port>
    </node>
    </zookeeper-servers>
    <networks>
    <ip>::/0</ip>
    </networks>
    <!--压缩相关配置-->
    <clickhouse_compression>
    <case>
    <min_part_size>10000000000</min_part_size>
    <min_part_size_ratio>0.01</min_part_size_ratio>
    <method>lz4</method> <!--压缩算法lz4压缩比zstd快, 更占磁盘-->
    </case>
    </clickhouse_compression>
    </yandex>

7、users.xml中可以配置密码。config.xml中需要注意配置。第一个配置为本节点hostname即可。第二个配置为0.0.0.0即可

8）过程中还发现/etc/localtime文件没有导致的无法启动的问题

ln -s /usr/share/zoneinfo/US/Pacific localtime

9）clickhouse-server --daemon 启动节点（我这里配置了两个）

10）clickhouse-client  -u default --password password访问

11)建表语句。建表中的{replica}既以下截图的位置

需要对照select * from system.clusters中的一致

node04
create table shard1.back_replica(cw_username String, cw_time DateTime,cw_age int)ENGINE = ReplicatedMergeTree('/clickhouse/tables/shard1/back_replica', '1')  PARTITION BY toYYYYMM(cw_time) order by (cw_time) SETTINGS index_granularity = 8192;

create table shard2.back_replica(cw_username String,cw_time DateTime,cw_age int)ENGINE = ReplicatedMergeTree('/clickhouse/tables/shard2/back_replica', '2') PARTITION BY toYYYYMM(cw_time) order by (cw_time) SETTINGS index_granularity = 8192;

node05
CREATE TABLE shard1.back_replica(cw_username String, cw_time DateTime, cw_age int) ENGINE = ReplicatedMergeTree('/clickhouse/tables/shard1/back_replica', '2') PARTITION BY toYYYYMM(cw_time) ORDER BY cw_time SETTINGS index_granularity = 8192;

CREATE TABLE shard2.back_replica (`cw_username` String, `cw_time` DateTime, `cw_age` Int32) ENGINE = ReplicatedMergeTree('/clickhouse/tables/shard2/back_replica', '1') PARTITION BY toYYYYMM(cw_time) ORDER BY cw_time SETTINGS index_granularity = 8192;

12）A一个节点中的一个shard写入。另一个节点查询依然能查到。此时既完成了一个2个shard且互为副本的高可用ck集群
