我怎么知道RabbitMQ应用程序是否已经启动 [英] How can I know whether RabbitMQ application has started

问题描述

我有一个C＃代码，在Windows Server 2012 R2上安装了Rabbitmq 3.7.4，erlang 20.2，我需要知道应用程序（而非服务）何时启动。运行 rabbitmq-service install 和 rabbitmq-service start 后，我正在寻找一个命令行，该命令行指示应用程序正在运行。我知道 wait pid_file，wait --pid pid 命令，但是无法在我的计算机上找到pid文件。 documantaion表示：

I have a c# code that installs rabbitmq 3.7.4, erlang 20.2 on windows server 2012 R2 and I need to know when the application (not the service) has started. After running rabbitmq-service install and rabbitmq-service start I'm looking for a command line that will indicate that the application is running. I'm aware of the wait pid_file, wait --pid pid command but can't locate the pid file on my machine. The documantaion says:

此命令将等待RabbitMQ应用程序在节点上启动。如果指定了pidfile，它将等待创建pid文件。

This command will wait for the RabbitMQ application to start at the node. It will wait for the pid file to be created if pidfile is specified

指定的位置？

rabbitmq-echopid.bat返回：

rabbitmq-echopid.bat returns:

系统找不到指定的路径。

The system cannot find the path specified.

推荐答案

在Windows上，RabbitMQ默认情况下不会创建PID文件，因此您必须先找到PID，然后以一个参数： rabbitmqctl.bat wait -P PID

On Windows, RabbitMQ does not create a PID file by default, so you have to discover the PID and then pass it as an argument: rabbitmqctl.bat wait -P PID

要发现PID，可以使用以下命令运行以下命令RabbitMQ节点的名称：

To discover the PID, you can run the following using the name of your RabbitMQ node:

.\rabbitmq-echopid.bat rabbit@my-hostname

这时，存在一个错误，其中系统找不到... 将在回显PID之前回显。我提交了此错误，并且很快就会修复，但与此同时您可以编辑 rabbitmq-echopid.bat 脚本，将！TDP0！更改为％TDP0 ％。

At this time, there is a bug where The system cannot find... will be echoed before the PID is echoed. I filed this bug and will have a fix in soon, but in the meantime you can edit the rabbitmq-echopid.bat script to change !TDP0! to %TDP0%.

您还可以使用任何其他Windows工具来找到 erl.exe 进程-有关 wmic.exe 的示例，请参见脚本，也可以使用 tasklist 或Powershell等。

You can also use any other Windows tool to find the PID of the erl.exe process running RabbitMQ - see the script for an example of wmic.exe, or you could use tasklist, or Powershell, etc.
