Chapter 10. Self-extracting releases

 

Erlang.mk allows you to package Relx releases as self-extracting archives. These archives contain all the files in the release and come in the form of a script that will extract and run the release automatically.

Erlang.mk容许您将Relx生成的发行版打包为自解压文件。 这些压缩包包含发行版中的全部文件，以脚本的形式提取并自动运行发行版。

 

This allows you to package the release as a single file that can then be executed.

这样你就能够将发行版打包为一个能够执行的文件。

 

This feature is currently experimental. Feedback is much appreciated.

这项功能目前是实验性的，全部反馈咱们都很是感谢。

 

10.1. Generating the self-extracting archive

10.1. 生成自解压文件

 

To generate a self-extracting release, all you need to do is pass the SFX=1 variable to Make when you build the release:

为了生成一个自解压发行版，你只须要在构建发行版时将 SFX=1变量传递给Make：

$ make SFX=1

 

This will create a self-extracting archive in $RELX_OUTPUT_DIR/<name>.run. For example if the release is named hello_world and $RELX_OUTPUT_DIR is the default, the file will be located at _rel/hello_world.run.

这将建立一个子解压文件$RELX_OUTPUT_DIR/<name>.run。例如，发行版命名为hello_world而且使用默认的$RELX_OUTPUT_DIR，生成的文件就是_rel/hello_world.run。

 

10.2. Running the release

10.2. 运行发行版

 

Simply execute the script to get started:

只需执行以下命令便可：

$ ./_rel/hello_world.run
Exec: /tmp/tmp.3eeEq7E1ta/erts-8.1/bin/erlexec ...
Root: /tmp/tmp.3eeEq7E1ta
/tmp/tmp.3eeEq7E1ta
Erlang/OTP 19 [erts-8.1] [source] [64-bit] [smp:4:4] ...

Eshell V8.1  (abort with ^G)
(hello_world@localhost)1>

 

As you can see the archive is extracted to a temporary directory before the release can be started.

如你所见，在发行版运行前，先将压缩包解压到一个临时目录。

 

The self-extracting script currently only supports starting the release in console mode.

自解压脚本当前仅支持以控制台模式启动发行版。
