企业官网建设流程全解析

生产级终极完整版（可直接交付）

一、环境拓扑（你的真实机器）

二、整体部署顺序（死记）

纯文本

纯文本

NFS → StorageClass → MySQL → Redis → RuoYi后端 → RuoYi前端

三、NFS + StorageClass（第一关）

1️⃣ NFS 服务器（143）

bash

bash

yum install -y nfs-utils rpcbind mkdir -p /opt/k8s chmod 777 /opt/k8s cat > /etc/exports << EOF /opt/k8s *(rw,sync,no_root_squash) EOF systemctl enable --now rpcbind systemctl enable --now nfs-server exportfs -r

✅ 验证：

bash

bash

showmount -e localhost

2️⃣ 所有节点

bash

bash

yum install -y nfs-utils

3️⃣ NFS Provisioner（血泪教训：RBAC 必须全）

rbac.yaml

yaml

yaml

apiVersion: v1 kind: ServiceAccount metadata: name: nfs-client-provisioner namespace: kube-system --- apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRole metadata: name: nfs-client-provisioner-runner rules: - apiGroups: [""] resources: ["persistentvolumes"] verbs: ["get","list","watch","create","delete"] - apiGroups: [""] resources: ["persistentvolumeclaims"] verbs: ["get","list","watch","update"] - apiGroups: ["storage.k8s.io"] resources: ["storageclasses"] verbs: ["get","list","watch"] - apiGroups: [""] resources: ["events","endpoints"] verbs: ["get","list","watch","create","update","patch"] --- apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRoleBinding metadata: name: run-nfs-client-provisioner subjects: - kind: ServiceAccount name: nfs-client-provisioner namespace: kube-system roleRef: kind: ClusterRole name: nfs-client-provisioner-runner apiGroup: rbac.authorization.k8s.io

provisioner.yaml

yaml

yaml

apiVersion: apps/v1 kind: Deployment metadata: name: nfs-client-provisioner namespace: kube-system spec: replicas: 1 strategy: type: Recreate selector: matchLabels: app: nfs-client-provisioner template: metadata: labels: app: nfs-client-provisioner spec: serviceAccountName: nfs-client-provisioner containers: - name: nfs-client-provisioner image: registry.cn-hangzhou.aliyuncs.com/iuxt/nfs-subdir-external-provisioner:v4.0.2 env: - name: PROVISIONER_NAME value: nfs-subdir-external-provisioner - name: NFS_SERVER value: 192.168.222.143 - name: NFS_PATH value: /opt/k8s volumeMounts: - name: nfs-root mountPath: /persistentvolumes volumes: - name: nfs-root nfs: server: 192.168.222.143 path: /opt/k8s

storageclass.yaml

yaml

yaml

apiVersion: storage.k8s.io/v1 kind: StorageClass metadata: name: nfs-storage annotations: storageclass.kubernetes.io/is-default-class: "true" provisioner: nfs-subdir-external-provisioner allowVolumeExpansion: true reclaimPolicy: Delete volumeBindingMode: Immediate parameters: archiveOnDelete: "false"

四、MySQL（StatefulSet，第二关）

坑 1：PVC Pending

原因：StorageClass 名字写错

解法：kubectl get sc

坑 2：MySQL 起不来

原因：NFS 权限

解法：runAsUser: 999

mysql-sts.yaml

#注意下mysql的中文问题，

RuoYi 乱码 ≠ 前端问题​

= MySQL 5.7 默认字符集 + K8s 没显式声明 utf8mb4

yaml

yaml

apiVersion: apps/v1 kind: StatefulSet metadata: name: mysql spec: serviceName: mysql replicas: 1 selector: matchLabels: app: mysql template: metadata: labels: app: mysql spec: securityContext: runAsUser: 999 fsGroup: 999 containers: - name: mysql image: mysql:5.7 args: - "--character-set-server=utf8mb4" - "--collation-server=utf8mb4_general_ci" env: - name: MYSQL_ROOT_PASSWORD value: "123456" - name: MYSQL_DATABASE value: "ry_vue" ports: - containerPort: 3306 volumeMounts: - name: mysql-data mountPath: /var/lib/mysql volumeClaimTemplates: - metadata: name: mysql-data spec: accessModes: ["ReadWriteOnce"] storageClassName: nfs-storage resources: requests: storage: 5Gi

mysql-svc.yaml

yaml

yaml

apiVersion: v1 kind: Service metadata: name: mysql spec: clusterIP: None selector: app: mysql ports: - port: 3306

五、Redis（StatefulSet，第三关）

坑 3：Redis 起不来

原因：UID 不匹配

解法：runAsUser: 0

redis-sts.yaml

yaml

yaml

apiVersion: apps/v1 kind: StatefulSet metadata: name: redis spec: serviceName: redis replicas: 1 selector: matchLabels: app: redis template: metadata: labels: app: redis spec: securityContext: runAsUser: 0 fsGroup: 0 containers: - name: redis image: redis:6.2 command: ["redis-server", "--appendonly", "yes"] ports: - containerPort: 6379 volumeMounts: - name: redis-data mountPath: /data volumeClaimTemplates: - metadata: name: redis-data spec: accessModes: ["ReadWriteOnce"] storageClassName: nfs-storage resources: requests: storage: 2Gi

redis-svc.yaml

yaml

yaml

apiVersion: v1 kind: Service metadata: name: redis spec: clusterIP: None selector: app: redis ports: - port: 6379

六、RuoYi 后端（Deployment，第四关）

坑 4：Java 连不上库

原因：用了mysql.server

解法：必须用 STS 域名

ruoyi-admin.yaml

yaml

yaml

apiVersion: apps/v1 kind: Deployment metadata: name: ruoyi-admin spec: replicas: 1 selector: matchLabels: app: ruoyi-admin template: metadata: labels: app: ruoyi-admin spec: containers: - name: ruoyi-admin image: ruoyi-admin:latest ports: - containerPort: 8080 env: - name: SPRING_DATASOURCE_URL value: > jdbc:mysql://mysql-0.mysql.default.svc.cluster.local:3306/ry_vue? useUnicode=true& characterEncoding=utf8& serverTimezone=Asia/Shanghai - name: SPRING_DATASOURCE_USERNAME value: root - name: SPRING_DATASOURCE_PASSWORD value: "123456" - name: SPRING_REDIS_HOST value: redis-0.redis.default.svc.cluster.local - name: SPRING_REDIS_PORT value: "6379"

ruoyi-admin-svc.yaml

yaml

yaml

apiVersion: v1 kind: Service metadata: name: ruoyi-admin spec: selector: app: ruoyi-admin ports: - port: 8080 targetPort: 8080

七、RuoYi 前端（Nginx，第五关）

坑 5：404

原因：没代理/prod-api

坑 6：502

原因：端口不一致

nginx.conf

nginx

nginx

server { listen 80; server_name localhost; root /usr/share/nginx/html; index index.html; location / { try_files $uri $uri/ /index.html; } location /prod-api/ { proxy_pass http://ruoyi-admin:8080/; proxy_setHeader Host $host; proxy_setHeader X-Real-IP $remote_addr; } }

Dockerfile

dockerfile

dockerfile

FROM nginx:alpine COPY ./dist/ /usr/share/nginx/html/ #dist是在当前目录下上传的文件夹 COPY nginx.conf /etc/nginx/conf.d/default.conf EXPOSE 80 CMD ["nginx", "-g", "daemon off;"]

ruoyi-frontend.yaml

yaml

yaml

apiVersion: apps/v1 kind: Deployment metadata: name: ruoyi-frontend spec: replicas: 1 selector: matchLabels: app: ruoyi-frontend template: metadata: labels: app: ruoyi-frontend spec: containers: - name: nginx image: my-frontend:v2 #这个是加过若以ui的nginx前端修改版 ports: - containerPort: 80 --- apiVersion: v1 kind: Service metadata: name: ruoyi-frontend spec: type: NodePort selector: app: ruoyi-frontend ports: - port: 80 targetPort: 80 nodePort: 30080

八、最终部署命令（严格执行）

bash

bash

kubectl apply -f rbac.yaml kubectl apply -f provisioner.yaml kubectl apply -f storageclass.yaml kubectl apply -f mysql-svc.yaml kubectl apply -f mysql-sts.yaml kubectl apply -f redis-svc.yaml kubectl apply -f redis-sts.yaml kubectl apply -f ruoyi-admin-svc.yaml kubectl apply -f ruoyi-admin.yaml kubectl apply -f ruoyi-frontend.yaml

#乱码问题，ruoyi jar的application.yml：

示例：spring:
datasource:
url: jdbc:mysql://localhost:3306/ry?useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai
