Clickhouse 集群安装(完整版)

前期准备

安装zookeeper

集群步骤

1.先安装四个单机的clickhouse

2.在四台机器上新建 /etc/metrika.xml 文件，生成两分片两副本集群

一、安装单机clickhouse(四台都操作,以Centos为例)

官网Centos/Ubuntu/Docker安装

1.1.在线安装

yum install yum-utils
rpm --import https://repo.clickhouse.tech/CLICKHOUSE-KEY.GPG
yum-config-manager --add-repo https://repo.clickhouse.tech/rpm/stable/x86_64
yum install clickhouse-server clickhouse-client

1.2.离线安装

下载地址换成  https://packages.clickhouse.com/rpm/stable/
下载地址换成  https://packages.clickhouse.com/rpm/stable/
下载地址换成  https://packages.clickhouse.com/rpm/stable/
wget https://repo.yandex.ru/clickhouse/rpm/stable/x86_64/clickhouse-common-static-20.12.5.14-2.x86_64.rpm
wget https://repo.yandex.ru/clickhouse/rpm/stable/x86_64/clickhouse-client-20.12.5.14-2.noarch.rpm
wget https://repo.yandex.ru/clickhouse/rpm/stable/x86_64/clickhouse-server-20.12.5.14-2.noarch.rpm
rpm -ivh clickhouse-common-static-20.12.5.14-2.x86_64.rpm
rpm -ivh clickhouse-server-20.12.4.5-2.noarch.rpm
rpm -ivh clickhouse-client-20.12.5.14-2.noarch.rpm

2.修改配置参数

# 修改配置文件路径权限
chmod -R 755 /etc/clickhouse-server/
# 修改config.xml,是本地和远程可登陆
vim /etc/clickhouse-server/config.xml
	<listen_host>0.0.0.0</listen_host>
# 修改users.xml,添加密码
vim /etc/clickhouse-server/users.xml
	<receive_timeout>800</receive_timeout>
	<send_timeout>800</send_timeout>
	<password>123456</password>
	<max_memory_usage>150000000000</max_memory_usage>
	<max_memory_usage_for_all_queries>170000000000</max_memory_usage_for_all_queries>
	<max_bytes_before_external_group_by>120000000000</max_bytes_before_external_group_by>
	<max_bytes_before_external_sort>120000000000</max_bytes_before_external_sort>

如果是只有一台机器想玩单机，现在已经装好了，启动就OK了

# 卸载及删除安装文件（需root权限）
yum list installed | grep clickhouse
yum remove -y clickhouse-common-static
yum remove -y clickhouse-server-common
rm -rf /var/lib/clickhouse
rm -rf /etc/clickhouse-*
rm -rf /var/log/clickhouse-server

二、生成 /etc/metrika.xml 配置文件

<?xml version="1.0"?>
<yandex>
    <!--ck集群节点-->
    <clickhouse_remote_servers>
        <!-- 集群名称 -->
        <test_ck_cluster>
            <!--分片1-->
            <shard>
                <weight>1</weight>
                <internal_replication>true</internal_replication>
                <replica>
                    <host>yc-nsg-h20</host>
                    <port>9000</port>
                    <user>default</user>
                    <password>123456</password>
                </replica>
                <!--复制集1-->
                <replica>
                    <host>yc-nsg-h21</host>
                    <port>9000</port>
                    <user>default</user>
                    <password>123456</password>
                </replica>
            </shard>
            <!--分片2-->
            <shard>
                <weight>1</weight>
                <internal_replication>true</internal_replication>
                <replica>
                    <host>yc-nsg-h22</host>
                    <port>9000</port>
                    <user>default</user>
                    <password>123456</password>
                </replica>
                <!--复制集2-->
                <replica>
                    <host>yc-nsg-h3</host>
                    <port>9000</port>
                    <user>default</user>
                    <password>123456</password>
                </replica>
            </shard>
        </test_ck_cluster>
    </clickhouse_remote_servers>
    <!--zookeeper相关配置-->
    <zookeeper-servers>
        <node index="1">
            <host>yc-nsg-h20</host>
            <port>2181</port>
        </node>
        <node index="2">
            <host>yc-nsg-h21</host>
            <port>2181</port>
        </node>
        <node index="3">
            <host>yc-nsg-h22</host>
            <port>2181</port>
        </node>
    </zookeeper-servers>
    <macros>
        <layer>01</layer>
        <shard>02</shard>
        <!--分片号,hostname-layer-shard -->
        <replica>yc-nsg-h22-01-02</replica>
        <!--当前节点IP-->
    </macros>
    <networks>
        <ip>::/0</ip>
    </networks>
    <!--压缩相关配置-->
    <clickhouse_compression>
        <case>
            <min_part_size>1073741824</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>

三、启动和验证

systemctl start clickhouse-server

clickhouse-client -u default --password 123456 --port 9000 -h yc-nsg-h21 --multiquery

select * from system.clusters;

或者登陆一下8123界面试一下，看能不能用
