FAQ

GPG Key Error

Errors during downloading metadata for repository 'rabbitmq_server':
  - Curl error (35): SSL connect error for https://github.com/rabbitmq/signing-keys/releases/download/2.0/rabbitmq-release-signing-key.asc [OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to github.com:443 ]

Solution: 如果外網有防火牆，必須開通 github.com，或者直接下載該 GPG key 檔，然後上傳到主機的目錄 /etc/pki/rpm-gpg，並修改 /etc/yum.repos.d/rabbitmq.repo
