# Verificar a assinatura do pacote do atendente do CloudWatch Os arquivos de assinatura GPG estão incluídos para pacotes do atendente do CloudWatch em servidores Linux. É possível usar uma chave pública para verificar se o arquivo de download do agente é original e sem modificações. Para o Windows Server, você pode usar o MSI para verificar a assinatura. Para computadores macOS, a assinatura está incluída no pacote para baixar o atendente. Para localizar o arquivo de assinatura apropriado, use a tabela apresentada a seguir. Para cada arquitetura e sistema operacional, é possível visualizar um link geral e links específicos para cada região. Se você usar os links específicos da região, substitua a região padrão (*us-east-1*) pela região apropriada da sua conta. Por exemplo, para o Amazon Linux 2023 e Amazon Linux 2 e a arquitetura x86-64, três dos links válidos são: + `https://amazoncloudwatch-agent.s3.amazonaws.com/amazon_linux/amd64/latest/amazon-cloudwatch-agent.rpm.sig` + `https://amazoncloudwatch-agent-us-east-1.s3.us-east-1.amazonaws.com/amazon_linux/amd64/latest/amazon-cloudwatch-agent.rpm` + `https://amazoncloudwatch-agent-eu-central-1.s3.eu-central-1.amazonaws.com/amazon_linux/amd64/latest/amazon-cloudwatch-agent.rpm` **nota** Para baixar o agente do CloudWatch, sua conexão deve usar o TLS 1.2 ou posterior. | Arquitetura | Plataforma | Link para fazer download | Link do arquivo de assinatura | | --- | --- | --- | --- | | x86-64 | Amazon Linux 2023 e Amazon

um servidor Linux** 1. Baixar a chave pública. ``` shell$ wget https://amazoncloudwatch-agent.s3.amazonaws.com/assets/amazon-cloudwatch-agent.gpg ``` 1. Importe a chave pública em seu token de autenticação. ``` shell$ gpg --import amazon-cloudwatch-agent.gpg gpg: key 3B789C72: public key "Amazon CloudWatch Agent" imported gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1) ``` Anote o valor da chave, pois ele será necessário na próxima etapa. No exemplo anterior, o valor da chave é `3B789C72`. 1.

Entre em contato com a Amazon Web Services. Depois de verificar a impressão digital, você pode usá-la para verificar a assinatura do pacote do atendente do CloudWatch. 1. Faça download do arquivo signature do pacote usando o **wget**. Para determinar o arquivo de assinatura correto, consulte a tabela anterior. ``` wget Signature File Link ``` 1. Para verificar a assinatura, execute **gpg --verify**. ``` shell$ gpg --verify signature-filename agent-download-filename gpg: Signature made Wed 29 Nov 2017 03:00:59 PM PST using RSA key ID 3B789C72 gpg: Good signature from "Amazon CloudWatch Agent" gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner.
