今天我们将深入探讨：：如何在 K8s 集群上部署 Compute storage coupled（存算耦合） 模式的 Doris 高可用集群？

本文，我将为您提供一份全面的实战指南，逐步引导您完成以下关键任务：

  1. 配置 Doris ConfigMap：实现自定义配置文件
  2. 配置 Doris Secret：管理特殊密码
  3. 配置 Doris Service：使用 NodePort 对外发布 Doris 服务
  4. 部署 Doris FE
  5. 部署 Doris BE
  6. Doris 用户初始化
  7. Doris 图形化管理概览

通过本文的指导，您将掌握在 K8s 上部署 Compute storage coupled 模式下的 Doris 集群的必备技能。

实战环境涉及软件版本信息

  • 操作系统：openEuler 22.03 LTS SP3 x86_64
  • KubeSphere：v3.4.1
  • Kubernetes：v1.28.8
  • KubeKey: v3.1.1
  • Doris： 3.0.2

1. 部署方案规划

Doris 官方提供了 Doris Operator 工具，用于在 K8s 集群中部署和管理 Doris 集群，详细信息可以查阅Doris 快速部署文档 。

一些特殊环境或是运维人员自身能力、喜好等原因，不适合使用 Doris Operator。这就需要我们使用 Kubectl 利用自定义资源清单，部署 Doris 集群。

本文基于资源清单实现了 Doris 集群的部署，生产环境建议使用 Doris Operator，部署方法也更加简单。

在 K8s 上部署 Doris 集群有两种架构方案：

  • Compute storage coupled（存算耦合）
  • Compute storage decoupled（存算分离）

本文选择了适用于中小规模场景的 Compute storage coupled 方案。Compute storage decoupled 的部署和维护更加复杂，更多细节请查阅官方文档。

1.1 部署架构图

1.2 准备持久化存储

本实战环境使用 NFS 作为 K8s 集群的持久化存储，新集群可以参考探索 K8s 持久化存储之 NFS 终极实战指南 部署 NFS 存储。

1.3 命名空间

Doris 集群所有资源部署在命名空间 opsxlab内。

1.4 前提准备

  1. 准备 root 密码

编写 Python 脚本 hm.py，生成 2 阶段 SHA-1 加密的密码。

#!/bin/python

import hashlib

# 原始密码
original_password = "PleaseChangeMe"

# 第一次SHA-1哈希运算
first_hash = hashlib.sha1(original_password.encode('utf-8')).hexdigest()

# 第二次SHA-1哈希运算
first_hash_bytes = bytes.fromhex(first_hash)
second_hash = hashlib.sha1(first_hash_bytes).hexdigest()

# 输出两阶段加密后的密码
print("*" + second_hash)

生成密码，记录备用。

$ python3 hm.py
*aa7530f7c48740e92a4c0d2138324611e314d397

2. 部署 Doris 集群

2.1 创建 ConfigMap

  1. 创建 Doris FE 配置文件

请使用 vi 编辑器，创建资源清单文件 doris-cluster-fe-conf.yaml，并输入以下内容：

apiVersion: v1
kind: ConfigMap
metadata:
  name: doris-cluster-fe-conf
  labels:
    app.kubernetes.io/component: fe

    http_port = 8030
    rpc_port = 9020
    query_port = 9030
    edit_log_port = 9010
    arrow_flight_sql_port = -1

    # Choose one if there are more than one ip except loopback address.
    # Note that there should at most one ip match this list.
    # If no ip match this rule, will choose one randomly.
    # use CIDR format, e.g. 10.10.10.0/24 or IP format, e.g. 10.10.10.1
    # Default value is empty.
    # priority_networks = 10.10.10.0/24;192.168.0.0/16

    # Advanced configurations
    # log_roll_size_mb = 1024
    # INFO, WARN, ERROR, FATAL
    sys_log_level = INFO
    # NORMAL, BRIEF, ASYNC
    sys_log_mode = ASYNC
    # sys_log_roll_num = 10

    enable_fqdn_mode = true
    initial_root_password = *aa7530f7c48740e92a4c0d2138324611e314d397

说明： 配置文件在 FE 默认配置基础上，增加了 initial_root_password 配置项，值是前面用 Python 生成的2段加密的密码，生产环境请根据需要调整。

  1. 创建 Doris BE 配置文件

  1. 创建资源

执行下面的命令，创建资源。

kubectl apply -f doris-cluster-fe-sts.yaml -n opsxlab
  1. 验证资源

执行下面的命令，查看创建结果（初次创建比较慢）。

$ kubectl get sts,pod -n opsxlab
NAME                                READY   AGE
statefulset.apps/doris-cluster-fe   3/3     117s

pod/doris-cluster-fe-2   1/1     Running   0          80s

2.5 创建 Doris BE

使用 StatefulSet 部署 Doris BE 服务，需要创建 StatefulSet 和 HeadLess 两种资源。

  1. 创建资源清单

请使用 vi 编辑器，创建资源清单文件 doris-cluster-be-sts.yaml，并输入以下内容：

kind: StatefulSet
apiVersion: apps/v1
metadata:
  name: doris-cluster-be
  labels:
    app.kubernetes.io/component: doris-cluster-be

  1. 创建资源

执行下面的命令，创建资源。

kubectl apply -f doris-cluster-be-sts.yaml -n opsxlab
  1. 验证资源

执行下面的命令，查看创建结果。

$ kubectl get sts,pod -n opsxlab

3. 认证管理

登录 Doris 查看用户信息并设置密码。

  • 执行下面的命令，进入 Pod doris-fe-0 的终端，连接 Doris 服务。
kubectl exec -n opsxlab -it doris-cluster-fe-0 -- /bin/bash
  • 在 doris-fe-0 内，执行 mysql 命令，使用 root 用户访问 Doris 服务对应的 NodePort 端口（需要密码），并查看用户及权限。
root@doris-cluster-fe-0:/opt/apache-doris# mysql -uroot -P31622 -h192.168.9.91 -p
Enter password:

4. Doris 图形化功能概览

Doris FE 内置 Web UI。用户无须安装 MySQL 客户端，即可通过内置的 Web UI 进行 SQL 查询和其它相关信息的查看。

使用浏览器，打开 FE 服务 http-port 端口 8030 对应的 NodePort 31620，例如 http://192.168.9.91:31620，打开 Doris 内置的 Web 控制台。
