無法連接到本地 azure cosmosdb 模擬器

Question

我在我的 Win10 計算機上安裝了Azure CosmosDB 模擬器，並且可以看到啟動頁面：

但是當我嘗試通過 Robo3T 或命令行連接到數據庫時，它不起作用。 我使用以下 cmd ：

mongo mongodb://localhost:foofoojf5%2FR%2Bob0N8A7Cgv30VRDJIWEHLM%2B4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw%2FJw%3D%3D@localhost:10255/admin?ssl=true

我遇到了以下問題：

2019-07-18T14:33:27.265+0200 W NETWORK [thread1] 5000ms 毫秒后無法連接到 127.0.0.1:10255，放棄。 2019-07-18T14:33:27.266+0200 E QUERY [thread1] 錯誤：無法連接到服務器 localhost:10255，連接嘗試失敗：connect@src/mongo/shell/mongo.js:237:13 @(connect ):1:6 異常：連接失敗

它是本地的，所以我認為沒有端口問題。 是否可能與本地證書或我的公司防火牆有關？

Answer 1

我用 ROBO3T 工具連接了 mongo 模擬器，請看我的配置。

首先，從此鏈接獲取模擬器連接字符串。

mongodb://localhost:C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw==@localhost:10255/admin?ssl=true

然后創建連接配置：

就我而言，要為 MongoDb 交互 Azure CosmosDb API，我們需要在 %localappdata%\\CosmosDbEmulator 下創建一個專用的新文件夾並啟用 MongoDb 端點 v3.6（請參閱下面步驟 1中的 PowerShell 命令）。

注意：無論出於何種原因，如果 CosmosDb 模擬器重置為默認文件夾路徑 %localappdata%\\CosmosDbEmulator（或）無法在 Robo 3T 中連接，則始終在步驟 1 中再次執行以下 PowerShell 腳本。

注意：從 Robo 3T v1.4 開始，我們在連接設置對話框中沒有 SSL 選項卡。 相反，我們有一個選項卡 TLS。

1. Download and install Azure CosmosDb Emulator from https://docs.microsoft.com/en-us/azure/cosmos-db/local-emulator?tabs=powershell%2Cssl-netstd21
2. Download and install Robo 3T (1.4.2 or latest) from https://robomongo.org/download
3. To show Azure CosmosDb emulator related database(s) in Robo 3T client app

Step 1
- Launch Azure CosmosDb Emulator 
  (Optional: Just to check CosmosDbEmulator is started successfully)
- Open Powershell as administrator and execute below commands

  # PowerShell Script
  # Change directory to default location where CosmosDb emulator is installed.
  cd\
  cd '.\Program Files\Azure Cosmos DB Emulator\'
             
  # [Optional] If any cosmosDb emulator instance is running then shutdown
  .\Microsoft.Azure.Cosmos.Emulator.exe /shutdown
        
  # To interact Azure CosmosDb API for MongoDb, create a new folder "<MongoDb>" under 
  # %localappdata%\CosmosDbEmulator and enable MongoDb endpoint v3.6
  .\Microsoft.Azure.Cosmos.Emulator.exe /DataPath="$env:localappdata\CosmosDBEmulator\MongoDb" /EnableMongoDbEndpoint=3.6

Step 2      
- Now CosmosDb emulator will be successfully started,
  and launches the URL https://localhost:8081/_explorer/index.html in the browser
- Note down MongoDb connection string details from browser which will be required 
  while creating new Robo 3T connection. The default MongoDb connection string format is 
  mongodb://username:password@host:port/[database]?ssl=true
    - Username: localhost
    - Password (Primary Key): C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw==
    - Port: 10255
    - Database: admin
    
Step 3
- Launch Robo 3T
- Click on Create new connection 
- In "Connection" tab
    - Provide Name of the connection as "<CosmosDbEmulator>"
    - Add port number as 10255
        
- In "Authentication" tab provide details noted down in previous Step 2
    - Check "Perform authentication"
    - Add Database as "admin"
    - Add Username as "https://localhost:8081"
    - Add Password as "C2y6yDjf5/R+ob0N8A7Cgv30VRDJIWEHLM+4QDU5DE2nQ9nDuVTqobD4b8mGGyPMbIZnqyMsEcaGQy67XIw/Jw=="
        
- In "TLS" tab provide
    - Check "Use TLS protocol"
    - From Authentication Method dropdown select "Self-signed Certificate"
        
- Click on "Test" button. 
    - It should successfully connects to localhost:10255 via TLS tunnel
    - It should successfully authorise to database "admin"
    
- Click on "Save" button    
- Click on "Connect" button. 
    - It will show the admin database and its related collections.
