我正在运行Julien Ponge的书"Vert中的第三章Infinispan示例。x在行动"在MacOS 11.3上。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chapter3文件夹中执行
./gradlew run -PmainClass=chapter3.cluster.FirstInstance -Pjvmargs="-Djava.net.preferIPv4Stack=true"
结果是
failed sending discovery request to /228.6.7.8:46655
这在Windows中工作。我想知道MacOS多播是否有问题?我尝试按照以下步骤启用多播，但仍然得到相同的错误:https://blogs.agilefaqs.com/2009/11/08/enabling-multicast-on-your-macos-unix/
全输出:

@tsegismont提供了有效的答案。https://gist.github.com/rafaeltuelho/208568668e4205bd9b93
为224.0.0.1-231.255.255.254添加组播路由:
sudo route add -net 224.0.0.0/5 127.0.0.1
为232.0.0.1-239.255.255.254添加组播路由
sudo route add -net 232.0.0.0/5 192.168.1.3
对于230.0.0.0，我绑定到192.168.1.3
