更改 Erlang 中的默认“home"路径以解决 RabbitMQ 启动错误 [英] Change Default 'home' Path in Erlang to Resolve RabbitMQ Start Up Error

问题描述

我是 rabbitmq 的新手，并且是 erlang 的新手.我遇到了一个问题，我无法启动 rabbitmq，因为 .erlang.cookie 的主"位置已更改.我已经运行了命令

I'm new to rabbitmq and by association new to erlang. I'm running into a problem where I cannot start rabbitmq as the 'home' location for the .erlang.cookie has been changed. I've run the command

init:get_argument(home).

返回

{ok,[["H:\"]]}

这是一个问题，因为这是我并不总是可以访问的网络驱动器.我需要能够将主"目录更改为本地目录.

this is an issue, as this is a network drive I do not always have access to. I need to be able to change the 'home' directory to something local.

当我跑步时

rabbitmqctl status

它给了我以下错误:

{error_logger,{{2013,7,5},{14,47,10}},"Failed to create cookie file 'h:/.erlang.cookie': enoent",[]}

这再次让我相信 home 论点存在问题.我需要能够将此位置更改为本地位置.

which again leads me to believe that there is an issue with the home argument. I need to be able to change this location to something local.

版本:

Erlang R16B01 32 bit
RabbitMQ 3.1.3
Running on Win7

我已经卸载并重新安装了多次，希望能解决这个问题.我正在寻找一种方法来更改 erlang 中的家"位置，以便 rabbitmq 可以正常启动.

I have uninstalled and reinstalled multiple times hoping to resolve this. I am looking for a way to change the 'home' location in erlang so rabbitmq can properly start.

推荐答案

我想出的解决方案是不要打扰已安装的服务.我使用 rabbitmq-server.bat 启动服务，SET HOMEDRIVE=C: 在文件的开头.我打算从父服务运行它，以便我可以在服务器上安装它.

The solution I came up with was to not bother with the installed service. I used the rabbitmq-server.bat to start the service, SET HOMEDRIVE=C: at the start of the file. I'm planing to run this from a parent service so that I can install this on servers.

earlang 和 rabbitMQ 开发人员的最后说明；为自己的目的使用预先存在的环境变量是错误的.您应该创建自己的，或者最好将这些东西放在配置文件中.告诉人们与他们的系统管理员交谈以更改 HOMEDRIVE 和 APPDATA 变量至少可以说是傲慢的.

Final note to earlang and rabbitMQ developers; using pre-existing environment variables for you own purposes is just wrong. You should create your own, or better yet put this stuff in a configuration file. Telling people to talk to their system administrators to change the HOMEDRIVE and APPDATA variables is arrogant to say the least.
