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
- 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
- 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
data:

- 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
- 验证资源
执行下面的命令，查看创建结果。
$ kubectl get sts,pod -n opsxlab NAME READY AGE statefulset.apps/doris-cluster-be 3/3 37s statefulset.apps/doris-cluster-fe 3/3 12m NAME READY STATUS RESTARTS AGE pod/doris-cluster-be-0 1/1 Running 0 37s pod/doris-cluster-be-1 1/1 Running 0 37s pod/doris-cluster-be-2 1/1 Running 0 37s pod/doris-cluster-fe-0 1/1 Running 0 13m pod/doris-cluster-fe-1 1/1 Running 0 13m pod/doris-cluster-fe-2 1/1 Running 0 12m
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:

提示：输出结果显示 root 用户设置了密码，admin 用户没有设置密码。
- 执行 mysql 命令，使用 admin 用户登录 Doris（无需密码）

- 请立即为管理员（admin）账户设置密码。
SET PASSWORD FOR 'admin'@'%' = PASSWORD('PleaseChangeMe');
- 再次查看权限，admin 用户的 Password 项的值已经变成 Yes。

退出 MySQL 控制台，再次使用 admin 用户登录，不输入密码，提示权限拒绝。

再次使用 admin 用户登录，输入密码，可以登录 Doris 系统。
