Erlang在生产中启动应用程序 [英] Erlang start application in production

问题描述

当我在本地主机上测试我的erlang应用程序时，我有一个脚本启动服务器，如下所示：

When I'm testing my erlang application on localhost, I have a script that starts the server that looks like the following:

#!/bin/sh
PWD="$(pwd)"
NAME="$(basename $PWD)"
erl -pa "$PWD/ebin" deps/*/ebin -boot start_sasl \
    -name devnode@127.0.0.1 \
    -s reloader \
    -s $NAME \
    -setcookie some_random_cookie \
    +K true \
    +P 65536 

这将提示打开Erlang shell从那里我会输入：

This prompts open the Erlang shell and from there I would type something like:

应用程序：start（myapp）

这对于开发目的来说很好，但是如何在生产中部署？到目前为止，我可以想到这样做的唯一方法是通过启动屏幕过程并将其分离出来。我不认为应该是这样。我正在使用钢筋，如果这有帮助。

This is fine for development purposes, but how do I deploy this in production? As of right now, the only way I can think of doing this is by starting a screen process and detaching from it. I don't think that should be the case. I am using rebar, if that helps at all.

推荐答案

听起来像你想使用自定义的引导脚本。一个引导脚本告诉erlang系统什么开始。在您正在使用的脚本中，您正在设置引导脚本：

Sounds like you want to use a custom boot script. A boot script tells the erlang system what to start. In the script you're using, you're setting the boot script with:

-boot start_sasl

http://www.erlang.org/doc/system_principles/system_principles.html ，查找用户定义的启动脚本一节

http://www.erlang.org/doc/system_principles/system_principles.html, look for the section "User-Defined Boot Scripts"

更简单的选择可能是将您的应用程序转换为使用钢筋： https://github.com/basho/rebar。然后，您可以执行以下操作：

An easier option may be to convert your application to use rebar: https://github.com/basho/rebar. You would then be able to do the following:

./rebar compile generate

这将为应用程序创建一个发行版，然后允许您：

This will create a release for the application, allowing you to then:

./rel/<app_name>/bin/<app_name>

相同的原则，只是全部包装起来容易使用。

Same principles, just all wrapped up for easy use.
