1. 安装k3s集群

1.1 安装k3s（单节点快速体验）

# 使用root用户或sudo执行
curl -sfL https://get.k3s.io | sh -

# 验证安装
sudo kubectl get nodes  # 应显示一个节点状态为Ready
sudo systemctl status k3s

1.2 设置kubectl快捷方式（可选）

mkdir -p ~/.kube
sudo cp /etc/rancher/k3s/k3s.yaml ~/.kube/config
sudo chown $USER ~/.kube/config
export KUBECONFIG=~/.kube/config

2. 部署MySQL数据库

2.1 创建持久化存储卷（PVC）

# mysql-pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mysql-pvc
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 2Gi  # 生产环境建议5Gi以上

kubectl apply -f mysql-pvc.yaml

2.2 创建数据库密码Secret

kubectl create secret generic mysql-secret \
  --from-literal=root_password=your_secure_password \
  --from-literal=database=appdb

2.3 部署MySQL

# mysql-deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: mysql-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: mysql
  template:
    metadata:
      labels:
        app: mysql
    spec:
      containers:
        - name: mysql
          image: mysql:8.0
          env:
            - name: MYSQL_ROOT_PASSWORD
              valueFrom:
                secretKeyRef:
                  name: mysql-secret
                  key: root_password
            - name: MYSQL_DATABASE
              valueFrom:
                secretKeyRef:
                  name: mysql-secret
                  key: database
          ports:
            - containerPort: 3306
          volumeMounts:
            - mountPath: /var/lib/mysql
              name: mysql
