Blockchain Hyperledger锯齿无法启动devmode共识引擎

我正试图在Ubuntu 16.04上启动一个Hyperledger锯齿形网络。我是按照你的指示去做的

启动验证服务可以正常工作，但启动devmode共识引擎不起作用。发生了以下情况：

mdi@boromir:~$ sudo -u sawtooth devmode-engine-rust -vv --connect tcp://localhost:5050
ERROR | devmode_engine_rust: | ReceiveError: TimeoutError
DEBUG | sawtooth_sdk::messag | Disconnected outbound channel

DEBUG | zmq:547              | socket dropped
DEBUG | zmq:454              | context dropped
mdi@boromir:~$

验证服务正在运行，如下所示：

该输出时间为17:29，因此近一个小时未追加任何输出

我试图查看锯齿形设置：

mdi@boromir:~$ sawtooth settings list
Error: Unable to connect to "http://localhost:8008": make sure URL is correct
mdi@boromir:~$

我检查了哪些进程正在侦听哪些端口：

mdi@boromir:~$ netstat -plnt

有人知道验证器服务是启动连接还是一致性引擎吗？我的

锯齿设置列表

命令有什么问题？有人知道如何让共识引擎工作吗？谢谢。

我自己找到了答案。我有另一台机器，上面安装了Hyperledger锯齿。在该服务器上，验证程序日志有以下行：

[2019-03-08 14:39:02.478 INFO     interconnect] Listening on tcp://127.0.0.1:5050

端口5050用于中所述的通用发动机。这表明一致性引擎会启动到验证器服务的连接

那么为什么验证器服务没有监听我Ubuntu机器上的端口5050呢？因为设置事务处理器从未在Ubuntu机器上运行过。我根据Ubuntu教程中的命令启动了这个处理器：

sudo -u sawtooth settings-tp -v

---

然后验证程序继续并开始监听端口5050。因此，可以启动共识引擎。

为其他人的利益在此处添加评论。Hyperledger Sawtooth 1.2版及以后版本的验证器具有这样一种设计，即使用它注册一致性引擎，并且不会出现任何超时错误，如本问题所示。根据设置

sawtooth.consensis.engine.name

和

sawtooth.consensis.engine.version

将激活相应的引擎。在这两种情况下，设置TP都起作用，因此应该始终进行注册。
