doris on k8s 的安装部署

官方文档

1. 按照官网提供地址下载部署文件

在这里插入图片描述

2. 修改内核配置

sysctl -w vm.max_map_count=2000000

3. 根据服务器环境，修改doris_be.yml文件。

# 修改点11： 增加kube config的configmap（此处可不修改，直接使用本地节点配置）

    # 此处内容复制配置文件内容，如果server地址指向的为127.0.0.1，注意修改为实际节点IP
    # 一般为 /root/.kube/config 内容， rancher安装的rke2环境默认为/etc/rancher/rke2/rke2.yaml

5. 创建服务用于外部连接doris-svc.yaml

apiVersion: v1
kind: Service
metadata:
  name: doris-svc
  namespace: doris
spec:
  type: NodePort
  ports:
    - port: 8030
      nodePort: 30803
      name: "p8030"
    - port: 9030
      nodePort: 30903
      name: "p9030"
  selector:
    app: doris-follower-cluster1

6. 部署

kubectl create ns doris
kubectl apply -f doris_be.yml -n doris
kubectl apply -f doris_follower.yml -n doris
kubectl apply -f doris-svc.yaml -n doris

7. 访问及使用, 默认账号为root，无密码

# web端访问地址
http://[节点IP]:30803/login

# 使用mysql client连接地址
host: [节点IP]
port: 30903
user: root
pass: 

# 使用mysql client连接后可修改root密码
SET PASSWORD FOR 'root' = PASSWORD('your_password');
