macOS通过docker 搭建clickhouse，单机服务

安装配置

mkdir -p /app/cloud/clickhouse/data
mkdir -p /app/cloud/clickhouse/conf
mkdir -p /app/cloud/clickhouse/log

chmod -R 777 /app/cloud/clickhouse/data
chmod -R 777 /app/cloud/clickhouse/conf
chmod -R 777 /app/cloud/clickhouse/log

拉取镜像

docker pull yandex/clickhouse-server:20.3.5.21

查看 https://hub.docker.com/r/yandex/clickhouse-server/dockerfile 文件，EXPOSE 9000 8123 9009 了三个端口，而宿主机9000端口已被 MinIO 对象存储服务器占用，所以创建容器暴露该端口用9090替换

root@jazz-pc:~# docker ps --format "table {{.Names}} ------> {{.Ports}}" | grep minio
minio ------> 0.0.0.0:9000->9000/tcp

创建临时容器

docker run --rm -d --name=clickhouse-server \
--ulimit nofile=262144:262144 \
-p 8123:8123 -p 9009:9009 -p 9090:9000 \
yandex/clickhouse-server:20.3.5.21

复制临时容器内配置文件到宿主机

docker cp clickhouse-server:/etc/clickhouse-server/config.xml /app/cloud/clickhouse/conf/config.xml
docker cp clickhouse-server:/etc/clickhouse-server/users.xml /app/cloud/clickhouse/conf/users.xml

停掉临时容器

docker stop clickhouse-server

创建default账号密码

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

会输出明码和SHA256密码 SEGByR98 211371f5bc54970907173acf6facb35f0acbc17913e1b71b814117667c01d96d

创建root账号密码

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

会输出明码和SHA256密码 092j3AnV 35542ded44184b1b4b6cd621e052662578025b58b4187176a3ad2b9548c8356e

修改 /app/cloud/clickhouse/conf/users.xml
把default账号设为只读权限，并设置密码 yandex-->users-->default-->profile 节点设为 readonly 注释掉 yandex-->users-->default-->password 节点新增 yandex-->users-->default-->password_sha256_hex 节点，填入生成的密码
新增root账号

<root>
<password_sha256_hex>35542ded44184b1b4b6cd621e052662578025b58b4187176a3ad2b9548c8356e</password_sha256_hex>
     <networks incl="networks" replace="replace">
        <ip>::/0</ip>
    </networks>
    <profile>default</profile>
    <quota>default</quota>
</root>

创建容器

docker run -d --name=clickhouse-server \
-p 8123:8123 -p 9009:9009 -p 9090:9000 \
