Vert.x Infinispan 获取 "failed sending discovery request to/228.6.7.8:46655"

Question

我在 MacOS 11.3 上运行 Julien Ponge 的书“Vert.x In Action”中的第 3 章 Infinispan 示例。 https://github.com/jponge/vertx-in-action/tree/master/chapter3

public class FirstInstance {
    private static final Logger logger = LoggerFactory.getLogger(FirstInstance.class);

    public static void main(String[] args) {
        Vertx.clusteredVertx(new VertxOptions(), ar -> {
            if (ar.succeeded()) {
                logger.info("First instance has been started");
                Vertx vertx = ar.result();
                vertx.deployVerticle("chapter3.HeatSensor", new DeploymentOptions().setInstances(4));
                vertx.deployVerticle("chapter3.HttpServer");
            } else {
                logger.error("Could not start", ar.cause());
            }
        });
    }
}

下载示例代码后，在我做的chapter3文件夹中

./gradlew run -PmainClass=chapter3.cluster.FirstInstance -Pjvmargs="-Djava.net.preferIPv4Stack=true"

这导致

failed sending discovery request to /228.6.7.8:46655

这适用于 Windows。我想知道 MacOS 多播是否存在问题？我尝试按照以下步骤启用多播，但仍然遇到相同的错误:https://blogs.agilefaqs.com/2009/11/08/enabling-multicast-on-your-macos-unix/

Answer 1

@tsegismont 提供了有效的答案。 https://gist.github.com/rafaeltuelho/208568668e4205bd9b93

为 224.0.0.1-231.255.255.254 添加多播路由:

sudo route add -net 224.0.0.0/5 127.0.0.1

为 232.0.0.1-239.255.255.254 添加多播路由

sudo route add -net 232.0.0.0/5 192.168.1.3

所以对于 230.0.0.0，我绑定(bind)到 192.168.1.3
