RabbitMQ开启SSL与SpringBoot连接测试

楔子

近期公司程序被安全扫描出 远程主机允许明文身份验证 中风险漏洞，查了下修复方案，RabbitMQ官方提供了SSL连接方式，而且 SpringBoot AMQP 也支持 SSL 连接。以下将配置RabbitMQ开启SSL 并使用 SpringBoot Demo 测试连接。

PS : 写文章时此配置还未安全扫描复测，如果测试通过，本人将更新此文章状态为验证通过。

配置 RabbitMQ 开启 SSL

本文基于 CentOS 7 + Git + OpenSSL + yum 安装的 RabbitMQ，需要读者提交安装好。其他方式也可变通参考本文。

生成证书

#克隆生成证书的仓库到当前目录
git clone --depth 1 https://github.com/Berico-Technologies/CMF-AMQP-Configuration.git
cd CMF-AMQP-Configuration/ssl
#生成ca证书，“MyRabbitMQCA”为自定义名称，名称任意。在当前目录下生成ca目录
sh setup_ca.sh MyRabbitMQCA
#生成服务端证书，第一个参数是服务端证书前缀，第二个参数是密码。密码任意，在当前目录下生成server目录
sh make_server_cert.sh rabbitmq-server 123456
#生成客户端证书，第一个参数是客户端证书前缀，第二个参数是密码。密码任意，在当前目录下生成client目录
sh create_client_cert.sh rabbitmq-client 654321

配置 RabbitMQ 服务端的证书如下：

ca/cacert.pem #CA证书
server/rabbitmq-server.cert.pem #服务端公钥
server/rabbitmq-server.key.pem  #服务端私钥

使用 RabbitMQ 服务端公钥证书生成 JKS 证书

# -alias后为别称，-file后是服务端公钥位置，-keystore后是输出JSK证书位置，此处相对路径
keytool -import -alias rabbitmq-server \
  -file server/rabbitmq-server.cert.pem \
  -keystore rabbitmqTrustStore -storepass changeit
#输入y回车

配置 RabbitMQ 客户端的证书如下：

client/rabbitmq-client.keycert.p12 #PKCS12证书，包含客户端所需公私钥及中间证书
rabbitmqTrustStore #服务端JKS格式公钥

默认 RabbitMQ 配置目录在 /etc/rabbitmq，我们创建个证书目录存放服务端证书

mkdir -p /etc/rabbitmq/ssl
#复制服务端必要证书
cp ca/cacert.pem \
server/rabbitmq-server.cert.pem \
server/rabbitmq-server.key.pem /etc/rabbitmq/ssl/

修改 RabbitMQ 配置文件

修改 RabbitMQ 配置文件 /etc/rabbitmq/rabbitmq.config，此文件默认不存在，需要手动创建

[{rabbit, [
    {ssl_listeners, [5671]},
    {ssl_options, [
        {cacertfile, "/etc/rabbitmq/ssl/cacert.pem"},
        {certfile,   "/etc/rabbitmq/ssl/rabbitmq-server.cert.pem"},
        {keyfile,    "/etc/rabbitmq/ssl/rabbitmq-server.key.pem"},
        {verify, verify_peer},
        {fail_if_no_peer_cert, true},
        {ciphers, [
            "ECDHE-ECDSA-AES256-GCM-SHA384","ECDHE-RSA-AES256-GCM-SHA384",
            "ECDHE-ECDSA-AES256-SHA384","ECDHE-RSA-AES256-SHA384",
            "ECDHE-ECDSA-DES-CBC3-SHA","ECDH-ECDSA-AES256-GCM-SHA384",
            "ECDH-RSA-AES256-GCM-SHA384","ECDH-ECDSA-AES256-SHA384",
            "ECDH-RSA-AES256-SHA384","DHE-DSS-AES256-GCM-SHA384",
            "DHE-DSS-AES256-SHA256","AES256-GCM-SHA384",
            "AES256-SHA256","ECDHE-ECDSA-AES128-GCM-SHA256",
            "ECDHE-RSA-AES128-GCM-SHA256","ECDHE-ECDSA-AES128-SHA256",
            "ECDHE-RSA-AES128-SHA256","ECDH-ECDSA-AES128-GCM-SHA256",
            "ECDH-RSA-AES128-GCM-SHA256","ECDH-ECDSA-AES128-SHA256",
            "ECDH-RSA-AES128-SHA256","DHE-DSS-AES128-GCM-SHA256",
            "DHE-DSS-AES128-SHA256","AES128-GCM-SHA256",
            "AES128-SHA256","ECDHE-ECDSA-AES256-SHA",
            "ECDHE-RSA-AES256-SHA","DHE-DSS-AES256-SHA",
            "ECDH-ECDSA-AES256-SHA","ECDH-RSA-AES256-SHA",
            "AES256-SHA","ECDHE-ECDSA-AES128-SHA",
            "ECDHE-RSA-AES128-SHA","DHE-DSS-AES128-SHA",
            "ECDH-ECDSA-AES128-SHA","ECDH-RSA-AES128-SHA","AES128-SHA"
        ]}
    ]}
]}].

主要配置项说明：

• ssl_listeners 指定 SSL协议的端口号，官方文档 5671
• ssl_options SSL 认证配置项
  • cacertfile CA 证书位置
  • certfile 公钥证书位置
  • keyfile 密钥证书位置
  • verify
    • verify_peer 客户端与服务端互相发送证书
    • verify_none 禁用证书交换与校验
  • fail_if_no_peer_cert
    • true 不接受没证书的客户端连接
    • false 接受没证书的客户端连接
  • ciphers 加密器（这个翻译不知道算不算对？）

重启 RabbitMQ

#关闭
rabbitmqctl stop
#启动
rabbitmq-server -detached

验证开启 SSL 是否成功

使用 Rabbitmq 自带的诊断工具查看端口监听状态及使用协议

#查看监听
rabbitmq-diagnostics listeners
#查看支持的TLS版本
rabbitmq-diagnostics --silent tls_versions

使用 OpenSSL CLI 工具验证证书是否有效

cd 生成证书的ssl目录
#使用客户端证书+CA证书连接RabbitMQ验证。本处MQ与生成证书是同一主机，其他情况请自行考虑。
openssl s_client -connect localhost:5671 \
  -cert client/rabbitmq-client.cert.pem \
  -key client/rabbitmq-client.key.pem \
  -CAfile ca/cacert.pem

除了命令行查看外，还可以通过管理界面查看，不过只能确定开启了 SSL 监听，无法确认证书是否通过验证。

编写 SpringBoot 代码连接测试

代码结构

只是使用 start.spring.io 生成的 Maven 工程，依赖了 WEB 和 AMQP

启动类 DemoApplication.java

package com.hellxz.rabbitmq.ssl;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

RabbitMQ客户端配置类 RabbitFanoutExchangeConfig.java

package com.hellxz.rabbitmq.ssl;

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.FanoutExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class RabbitFanoutExchangeConfig {
    public static final String FANOUT_EXCHANGE = "fanout.exchange";
    public static final String FANOUT_QUEUE1 = "fanout.queue1";

    @Bean(name = FANOUT_EXCHANGE)
    public FanoutExchange fanoutExchange() {
        return new FanoutExchange(FANOUT_EXCHANGE, true, false);
    }

    @Bean(name = FANOUT_QUEUE1)
    public Queue fanoutQueue1() {
        return new Queue(FANOUT_QUEUE1, true, false, false);
    }

    @Bean
    public Binding bindingSimpleQueue1(@Qualifier(FANOUT_QUEUE1) Queue fanoutQueue1,
                                       @Qualifier(FANOUT_EXCHANGE) FanoutExchange fanoutExchange) {
        return BindingBuilder.bind(fanoutQueue1).to(fanoutExchange);
    }
}

发消息测试类 TestController.java

package com.hellxz.rabbitmq.ssl;

import org.springframework.amqp.core.Message;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {
    @Autowired
    RabbitMQSenderService rabbitMQSenderService;

    @GetMapping("/test")
    public void sendMsg() {
        Message msg = new Message("hello world".getBytes());
        try {
            rabbitMQSenderService.send(RabbitFanoutExchangeConfig.FANOUT_EXCHANGE,
                    RabbitFanoutExchangeConfig.FANOUT_QUEUE1, msg);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

发消息服务 RabbitMQSenderService.java

package com.hellxz.rabbitmq.ssl;

import java.util.UUID;

import org.springframework.amqp.core.Message;
import org.springframework.amqp.rabbit.connection.CorrelationData;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class RabbitMQSenderService {
    @Autowired
    private RabbitTemplate rabbitTemplate;

    public void send(String exchange, String routingkey, Message message) {

        CorrelationData correlationId = new CorrelationData(UUID.randomUUID().toString());
        System.out.println("start send msg : " + message);
        rabbitTemplate.convertAndSend(exchange, routingkey, message, correlationId);
        System.out.println("end send msg : " + message);
    }
}

消息接收者 RabbitMQReciver.java

package com.hellxz.rabbitmq.ssl;

import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
class RabbitMQReciver {

    @RabbitListener(queues = RabbitFanoutExchangeConfig.FANOUT_QUEUE1)
    public void reciveLogAll(String msg) throws Exception {
        System.out.println("received msg:" + msg);
    }
}

配置文件 application.properties

server.port=8085

#基础配置请根据实际配置
spring.rabbitmq.host=192.168.56.104
#ssl协议端口
spring.rabbitmq.port=5671
spring.rabbitmq.username=admin
spring.rabbitmq.password=123456
spring.rabbitmq.virtual-host=/

#启用rabbitmq客户端SSL连接
spring.rabbitmq.ssl.enabled=true
#客户端PKCS12证书及密码
spring.rabbitmq.ssl.key-store=classpath:ssl/rabbitmq-client.keycert.p12
spring.rabbitmq.ssl.key-store-password=654321
#公钥证书及类型
spring.rabbitmq.ssl.trust-store=classpath:ssl/rabbitmqTrustStore
spring.rabbitmq.ssl.trust-store-type=JKS
#不校验主机名，默认开启会导致连接失败
spring.rabbitmq.ssl.verify-hostname=false

src/main/resources 下创建 ssl 目录，将 客户端证书和服务端JKS公钥复制到 ssl 目录中。

执行代码验证

运行 DemoApplication.java，查看控制台是否有报错：

如图，提示创建连接成功，说明已经连接成功了。

我们再调用 TestController.java 中定义的 /test 接口

消息发送与消费成功。
