Cadeias de conexão

➤ Use o menu suspenso Selecione a linguagem no canto superior direito para definir a linguagem dos exemplos a seguir.

Você pode usar strings de conexão para definir conexões entre instâncias do MongoDB e os seguintes destinos:

  • Seus aplicativos quando você se conecta usando o drivers.

  • Ferramentas como MongoDB Compass e o MongoDB Shell (mongosh).

Conclua estas etapas para encontrar sua connection string.

Encontre sua connection string do MongoDB Atlas

Para localizar sua string de conexão do MongoDB Atlas usando Atlas CLI, instale e conecte a partir do Atlas CLI e execute o seguinte comando. Substitua <clusterName> pelo nome do MongoDB Atlas cluster e substitua <projectId> pelo ID do projeto.

atlas clusters connectionStrings describe <clusterName> --projectId <projectId>

Para saber mais, consulte descrição de connectionStrings em cluster do Atlas.

Para localizar sua string de conexão do MongoDB Atlas na IU do Atlas, siga estas etapas:

1

Na interface do usuário do MongoDB Atlas, acesse a página Clusters do seu projeto.

  1. Se ainda não tiver sido exibido, selecione a organização que contém seu projeto no menu Organizations na barra de navegação.

  2. Se ainda não estiver exibido, selecione seu projeto no menu Projects na barra de navegação.

  3. Na barra lateral, clique em Clusters sob o título Database.

    A página Clusters é exibida.

2

Abra a caixa de diálogo Connection Method.

  1. Clique em Connect para o cluster ao qual você deseja se conectar.

  2. Clique em Choose a Connection Method. O MongoDB Atlas seleciona Standard Connection por padrão. Para se conectar usando um endpoint privado, selecione Private Endpoint.

3

Escolha um método de conexão.

Para se conectar ao seu aplicativo, clique em Drivers. Para se conectar usando ferramentas, clique na ferramenta que deseja usar para acessar seus dados.

4

Siga as instruções para o método de conexão que você selecionou.

  1. Se você selecionou Drivers, selecione seu driver e versão. Se você selecionou uma ferramenta, faça o download da ferramenta.

  2. Selecione Connect To Cluster.

  3. Copie a string de conexão. Substitua <password> e <username> na string de conexão pelas credenciais do usuário do banco de dados.

Sua string de conexão do MongoDB Atlas é semelhante ao exemplo a seguir:

mongosh "mongodb+srv://cluster0.example.mongodb.net myFirstDatabase" --apiVersion 1 --username myDatabaseUser
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/
mongodb+srv://myDatabaseUser:D1fficultP%40ssw0rd@cluster0.example.mongodb.net/?retryWrites=true&w=majority

Encontre a connection string do seu sistema auto-hospedado

Se você estiver conectado à implantação da MongoDB Enterprise auto-hospedada ou MongoDB Community, execute o método db.getMongo() para retornar a string de conexão.

Se não estiver conectado ao seu sistema, você poderá determinar sua string de conexão com base no tipo de conexão que deseja usar. Consulte Formato de conexão SRV para conhecer a sintaxe da string de conexão SRV ou Formato de connection string padrão para conhecer a sintaxe da string de conexão padrão.

Sua cadeia de conexão auto-hospedada é semelhante aos exemplos a seguir:

A cadeia de conexão do conjunto de réplicas a seguir inclui estes elementos:

  • A opção replicaSet

  • O(s) nome(s) de host da(s) instância(s) mongod conforme listado(s) na configuração do conjunto de réplicas

  • Ele se autentica como usuário myDatabaseUser com a senha D1fficultP%40ssw0rd para forçar o controle de acesso
