netty源码阅读之服务端启动

netty服务端启动分为以下几个过程：

1、[服务端channel的创建][channel]

2、[服务端channel的初始化][channel 1]

3、[注册selector][selector]

4、[服务端端口的绑定][Link 1]

我将通过以下用户的代码，后面分几篇文章为大家讲解：

public final class Server {
    
        public static void main(String[] args) throws Exception {
            EventLoopGroup bossGroup = new NioEventLoopGroup(1);
            EventLoopGroup workerGroup = new NioEventLoopGroup();
    
            try {
                ServerBootstrap b = new ServerBootstrap();
                b.group(bossGroup, workerGroup)
                        .channel(NioServerSocketChannel.class)
                        .childOption(ChannelOption.TCP_NODELAY, true)
                        .childAttr(AttributeKey.newInstance("childAttr"), "childAttrValue")
                        .handler(new ServerHandler())
                        .childHandler(new ChannelInitializer<SocketChannel>() {
                            @Override
                            public void initChannel(SocketChannel ch) {
                                ch.pipeline().addLast(new AuthHandler());
                                //..
    
                            }
                        });
    
                ChannelFuture f = b.bind(8888).sync();
    
                f.channel().closeFuture().sync();
            } finally {
                bossGroup.shutdownGracefully();
                workerGroup.shutdownGracefully();
            }
        }
    }

看完下面几篇文章，需要回答以下几个问题？

1、服务端的socket在哪里初始化？

2、在哪里进行accept连接？
