rabbitmq使用TLS支持SSL加密处理

 三十的狼 2021-04-02

最近在开发过程中， 有收到要求，rabbitmq 不能使用明文传输，常规想法就是TLS加密传输。看到rabbitmq 官网有提供TLS支持的说明。

Rabbitmq 加密传输由2种方式：

  1. 使用TLS加密直连
  2. 通过类似HA代理的方式从https转换成http 比如nginx, TLS_termination_proxy等都可以实现

官网也阐述了其他一些ssl支持的说明，这边就不介绍了。详细内容查阅官网

本文使用的rabbitmq 环境是，依赖docker 构建的rabbitmq 3.7.28版本的试验环境。

这边具体说一下，怎么构建TLS链接。

步骤1：使用TLS工具生成证书（开发测试环境）,生产环境建议使用商业的CA机构制作的证书文件

git clone https://github.com/michaelklishin/tls-gen tls-gen
cd tls-gen/basic
# private key password
make PASSWORD=密码
make verify
make info
ls -l ./result

其中make PASSWORD=密码 这一行命名是生成证书的过程，其他几行都是校验检测，可以不执行。

make PASSWORD=rabbit
python3 profile.py regenerate --password "rabbit" --common-name izbp1exs0zcohfndb4w0o5z --client-alt-name izbp1exs0zcohfndb4w0o5z --server-alt-name izbp1exs0zcohfndb4w0o5z --days-of-validity 3650 --key-bits 2048

Will verify client certificate against root CA
/mnt/tls-gen/basic/result/client_certificate.pem: OK
Will verify server certificate against root CA
/mnt/tls-gen/basic/result/server_certificate.pem: OK

上述命令会生成一些目录和证书文件

其中 result 目录，将CA buddle, server ,client 证书信息都汇集了一些，没有说明不同。

步骤2： 使用jdk的keytool 生成Java相关的配置信息, 中间过程，需要输入密码信息

keytool -import -alias server1   -file /mnt/rabbitmq/cert/server_certificate.pem  -keystore /mnt/rabbitmq/cert/rabbitstore

这个过程其实就是想rabbitmq 服务端的证书适配成符合Java规则的rabbitstore文件，注意这个是server端的certificate.

输出结果：

#####这边要求输入yes
Trust this certificate? [no]:  yes
Certificate was added to keystore

步骤3 配置rabbit MQ 配置文件

###授权方式, 其实就是再默认的基础上加一个EXTERNAL， 如果单独配置EXTERNAL， java 客户端会出现无法找不到auth_mechanisms的问题， 这个具体还不知道原因
auth_mechanisms.1 = PLAIN
auth_mechanisms.2 = AMQPLAIN
auth_mechanisms.3 = EXTERNAL

management_agent.disable_metrics_collector = true

ssl_options.client_renegotiation = false
ssl_options.secure_renegotiate = true


###禁止 明文tcp 连接
listeners.tcp = none

##管理端只允许本地连接
management.tcp.ip = 127.0.0.1
management.tcp.port = 15672
ssl_options.password=rabbit
###tls 端口
listeners.ssl.default = 5671
###tls工具，将需要的文件存放再result 目录中
ssl_options.cacertfile = /mnt/tls-gen/basic/result/ca_certificate.pem
ssl_options.certfile   = /mnt/tls-gen/basic/result/server_certificate.pem
ssl_options.keyfile    = /mnt/tls-gen/basic/result/server_key.pem


ssl_options.verify     = verify_peer
ssl_options.fail_if_no_peer_cert = true
ssl_cert_login_from = common_name

###支持TLS协议,
ssl_options.versions.1 = tlsv1
ssl_options.versions.2 = tlsv1.1
ssl_options.versions.3 = tlsv1.2

###TLS加密cipher 顺序
ssl_options.honor_cipher_order = true
ssl_options.honor_ecc_order    = true
###TLS加密cipher
ssl_options.ciphers.1=ECDHE-ECDSA-AES256-GCM-SHA384
ssl_options.ciphers.2=ECDHE-RSA-AES256-GCM-SHA384
ssl_options.ciphers.3=ECDH-ECDSA-AES256-GCM-SHA384

步骤4 Java 客户端连接测试

这边说明一下，官网的demo,大部分都是对的，但是会有些小问题
比如： 需要将factory.enableHostnameVerification(); 取消。

    public static void main(String[] args) throws Exception {
       // tls 执行命令中设置的密码 make PASSWORD=rabbit
        char[] passphrase = "rabbit".toCharArray();
        KeyStore ks = KeyStore.getInstance("PKCS12");
        //tls生成的result目录下的client_key.p12
        ks.load(new FileInputStream("D:\\work\\client_key.p12"), passphrase);

        KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
        kmf.init(ks, passphrase);
  //keytools 生成过程中，设置的密码
        char[] trustPassphrase = "rabbit".toCharArray();
        KeyStore tks = KeyStore.getInstance("JKS");
        //keytools 生成的rabbitstore
        tks.load(new FileInputStream("D:\\work\\rabbitstore"), trustPassphrase);

        TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");
        tmf.init(tks);

        SSLContext c = SSLContext.getInstance("TLSv1.2");
        c.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);

        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("IP地址");
        factory.setPort(5671);
        factory.useSslProtocol(c);
        factory.setUsername("admin");
        factory.setPassword("admin");
//        factory.enableHostnameVerification();

        Connection conn = factory.newConnection();
        Channel channel = conn.createChannel();
        channel.queueDeclare(QUEUE_NAME, false, false, false, null);
        System.out.println(" [*] Waiting for messages. To exit press CTRL+C");

        DeliverCallback deliverCallback = (consumerTag, delivery) -> {
            String message = new String(delivery.getBody(), "UTF-8");
            System.out.println(" [x] Received '" + message + "'");
        };
        channel.basicConsume(QUEUE_NAME, true, deliverCallback, consumerTag -> {
        });
    }

上面就是基本的rabbitmq tls 的基础支持。
