docker部署clickhouse

拉取镜像

最新镜像不加版本号即可

docker pull clickhouse/clickhouse-server:latest

宿主机创建目录

mkdir -p /usr/local/docker/clickhouse/conf /usr/local/docker/clickhouse/data /usr/lcoal/docker/clickhouse/log

启动临时容器获取配置文件

docker run --rm -d --name=temp-clickhouse-server clickhouse/clickhouse-server:latest

复制配置文件到宿主机

docker cp temp-clickhouse-server:/etc/clickhouse-server/users.xml /usr/local/docker/clickhouse/conf/users.xml
docker cp temp-clickhouse-server:/etc/clickhouse-server/config.xml /usr/local/docker/clickhouse/conf/config.xml

启动clickhouse

docker run -d --name=clickhouse-server \
-p 8123:8123 \
--volume=/usr/local/docker/clickhouse/conf/config.xml:/etc/clickhouse-server/config.xml \
--volume=/usr/local/docker/clickhouse/conf/users.xml:/etc/clickhouse-server/users.xml \
--volume=/usr/local/docker/clickhouse/data:/var/lib/clickhouse/ \
clickhouse/clickhouse-server:latest

修改用户名密码 test/123456

 <users>
    <test>         
 <password_double_sha1_hex>5d12e69be56929e66554d5f6a6628715e929d9fd</password_double_sha1_hex>
        <networks incl="networks" replace="replace">
            <ip>::/0</ip>
        </networks>
        <profile>default</profile>
        <quota>default</quota>
    </test>
</users>

备注：快速测试默认账户为default 密码为空

生成密码算法：SHA256和SHA1算法秘钥

SHA1 
     PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | openssl dgst -sha1 -binary | openssl dgst -sha1



     PASSWORD=$(base64 < /dev/urandom | head -c8); echo "$PASSWORD"; echo -n "$PASSWORD" | sha256sum | tr -d '-'

//两种加密在linux macos系统终端执行就好，第一行是你的密码（连接服务器使用），第二行是加密算法值 也就是需要配置的值。当然，这两种算法配置的xml节点不一样：
SHA1 password_double_sha1_hex
SHA256 password_sha256_hex

登录clickhouse

clickhouse-client -h ip地址 -d default -m -u default --password 123456

开放外网访问，vim config.xml 找到 listen_host 标签，修改为以下

<listen_host>0.0.0.0</listen_host>

在default库下新建表

create table t_user
(
    userId  Int32,
    appId   String,
    version String,
    regTime Date
)
    engine = MergeTree PARTITION BY toYYYYMM(regTime) ORDER BY userId SETTINGS index_granularity = 1;
