+# 分布式事件最佳实践
+
+## 安装 Dapr CLI 脚手架工具
+
+https://docs.dapr.io/zh-hans/getting-started/install-dapr-cli
+
+## 基于容器初始化 Dapr 运行时
+
+https://docs.dapr.io/zh-hans/getting-started/install-dapr-selfhost
+
+```shell
+dapr init
+```
+
+## 不用容器离线初始化 Dapr 运行时
+
+```shell
+dapr init -s
+```
+
+
+## 使用离线包初始化 Dapr 运行时
+
+https://docs.dapr.io/zh-hans/operations/hosting/self-hosted/self-hosted-airgap/
+
+```shell
+dapr init --from-dir C:\daprbundle
+```
+
+## 打开默认初始化目录
+
+```shell
+explorer "$env:USERPROFILE\.dapr"
+explorer "%USERPROFILE%\.dapr"
+```
+
+## 使用 Dashboard 查看 Dapr 运行状态
+
+```shell
+dapr dashboard
+```
+
+## 发布订阅配置分布式事件
+
+```shell
+/components/redis-pubsub.yaml
+```
+
+### 基于 Redis 发布订阅配置
+
+```yaml
+apiVersion: dapr.io/v1alpha1
+kind: Component
+metadata:
+  name: pubsub
+spec:
+  type: pubsub.redis
+  version: v1
+  metadata:
+  - name: redisHost
+    value: localhost:6379
+  - name: redisPassword
+    value: ""
+```
+
+### 基于 RabbitMQ 发布订阅配置
+
+```shell
+/components/rabbitmq-pubsub.yaml
+```
+
+```yaml
+apiVersion: dapr.io/v1alpha1
+kind: Component
+metadata:
+  name: pubsub
+spec:
+  type: pubsub.rabbitmq
+  version: v1
+  metadata:
+  - name: host
+    value: "amqp://guest:guestpwd@localhost:5672"
+  - name: durable
+    value: "false"

+### 使用 Dapr 命令启动 Sidecar 和应用程序
+    
+```shell
+dapr run --app-id myapp --dapr-http-port 3500 --dapr-grpc-port 50001 --app-port 5000 --log-level debug --config ./configuration/config.yaml --components-path ./components dotnet run
+```
+
+## 使用 Aspire 命令启动 Sidecar 和应用程序
+
+```shell
+dotnet add package Aspire.Hosting.Dapr
+```
+
+```csharp
+var pubsub = builder.AddDaprPubSub("pubsub", new DaprComponentOptions { LocalPath = "./DaprComponents/" });
+
+var productService = builder.AddProject<Projects.HelloWorld_ProductService>("productservice")
+    .WithReference(identityService)
+    .WithDaprSidecar()
+    .WithReference(pubsub);
+
+```
+
+
+## 使用 RabbitMQ 发布订阅配置
+
+```shell
+var username = builder.AddParameter("username", secret: true);
+var password = builder.AddParameter("password", secret: true);
+
+var messaging = builder.AddRabbitMQ("messaging", username, password);
+
+// Service consumption
+builder.AddProject<Projects.ExampleProject>()
+       .WithReference(messaging);
+```
