RabbitMQ SSL 連接適用於 Ubuntu14.04 機器，但不適用於 CentOS 6 機器
根據此處的文件，我已經在遠端伺服器上設置了 rabbitmq ssl 連接：https ://www.rabbitmq.com/ssl.html
我正在使用 java rabbitmqclient 連接到遠端伺服器並將 hello 消息發送到 rabbitmq-server 上的隊列，連接在我的本地 ubuntu 14.04 機器上工作正常，但在 centOS 6 機器上不能工作。
使用的打開 SSL s_client 命令：
openssl s_client -connect rabbitserver:5671 -cert cert.pem -key key.pem -CAfile cacert.pem在 ubuntu 上打開 SSL 輸出：

如何從我的 centOS 機器建立連接？
我相信您的問題與 Java 有關，您需要安裝 Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files，因為預設情況下，安裝的 java 僅啟用了有限的強度（顯然是為了允許全球分發 - 特殊的當地法律要求）
由於某些國家/地區的進口管制限制，捆綁在 Java Runtime Environment 或 JRE(TM)、8 環境中的 JCE 策略文件版本允許使用“強”但有限的密碼學。此下載包（包含此 README 文件的包）提供“無限強度”策略文件，其中不包含對加密強度的限制。
這個想法來自2次連接嘗試的比較，成功的一個狀態：
New, TLSv1/SSLv3, Cipher is ECDHE-RSA-AES256-SHA384雖然失敗的一個狀態（其中包括）：
