Question

我有以下内容，它创建一个Java gRPC服务器并尝试将其绑定到USD / tmp / foo：

["You"]

但是，EpollEventLoopGroup group = new EpollEventLoopGroup(); Server server = NettyServerBuilder.forAddress(new DomainSocketAddress("/tmp/foo")) .channelType(EpollServerSocketChannel.class) .bossEventLoopGroup(group) .workerEventLoopGroup(group) .addService(new Impl()) .build() .start(); server.awaitTermination();

失败了

bind(..) failed: Invalid argument

我检查过文件Exception in thread "main" java.io.IOException: Failed to bind at io.grpc.netty.NettyServer.start(NettyServer.java:231) at io.grpc.internal.ServerImpl.start(ServerImpl.java:151) at io.grpc.internal.ServerImpl.start(ServerImpl.java:75) at com.google.devtools.javatools.jade.pkgloader.GrpcLocalServer.main(GrpcLocalServer.java:60) Caused by: io.netty.channel.unix.Errors$NativeIoException: bind(..) failed: Invalid argument at io.netty.channel.unix.Errors.newIOException(Errors.java:117) at io.netty.channel.unix.Socket.bind(Socket.java:291) at io.netty.channel.epoll.AbstractEpollChannel.doBind(AbstractEpollChannel.java:714) at io.netty.channel.epoll.EpollServerSocketChannel.doBind(EpollServerSocketChannel.java:70) at io.netty.channel.AbstractChannel$AbstractUnsafe.bind(AbstractChannel.java:558) at io.netty.channel.DefaultChannelPipeline$HeadContext.bind(DefaultChannelPipeline.java:1283) at io.netty.channel.AbstractChannelHandlerContext.invokeBind(AbstractChannelHandlerContext.java:501) at io.netty.channel.AbstractChannelHandlerContext.bind(AbstractChannelHandlerContext.java:486) at io.netty.channel.DefaultChannelPipeline.bind(DefaultChannelPipeline.java:989) at io.netty.channel.AbstractChannel.bind(AbstractChannel.java:254) at io.netty.bootstrap.AbstractBootstrap$2.run(AbstractBootstrap.java:364) at io.netty.util.concurrent.AbstractEventExecutor.safeExecute(AbstractEventExecutor.java:163) at io.netty.util.concurrent.SingleThreadEventExecutor.runAllTasks(SingleThreadEventExecutor.java:403) at io.netty.channel.epoll.EpollEventLoop.run(EpollEventLoop.java:309) at io.netty.util.concurrent.SingleThreadEventExecutor$5.run(SingleThreadEventExecutor.java:858) at io.netty.util.concurrent.DefaultThreadFactory$DefaultRunnableDecorator.run(DefaultThreadFactory.java:138) at java.lang.Thread.run(Thread.java:745)不存在，我对它及其父目录有写权限，并且没有进程绑定到它（/tmp/foo）。我在Linux系统上。

我错过了一些明显的东西吗？

使用EpollServerDomainSocketChannel代替EpollServerSocketChannel解决了问题。

为了便于将来复制/粘贴，以下内容绑定（侦听）到UDS：

EpollEventLoopGroup group = new EpollEventLoopGroup();
Server server = NettyServerBuilder.forAddress(new DomainSocketAddress("/tmp/foo"))
    .channelType(EpollServerDomainSocketChannel.class)
    .workerEventLoopGroup(group)
    .bossEventLoopGroup(group)
    .addService(new Impl())
    .build()

将Java gRPC服务器绑定到unix域套接字
