做git拉进发动机场

Question

我正在部署我的rails应用程序到引擎场。

到目前为止，我拥有的是: 1.创建SSH嘿2.将公钥安装到Engine应用程序中。3.ssh deploy@my.server.ip.address

我被安置在家里/部署处，这不是执行git拉的合适地方。

我需要以这种方式进行部署的原因是，我的应用程序使用的是nmatrix gem，需要使用c++编译器手动安装。自动绑定器在获取宝石时出错，并停止。

更新:我想我的问题应该是，如何将nmatrix安装到EngineYard。这是我从调用获得的错误消息：

安装nmatrix的先决条件之一是让gcc > v4.7，但是EngineYard只有v4.5.4。有人知道如何升级gcc吗？我想我在运行Gentoo。

这个问题应该包括你想要拉的东西。

当您在ssh中时，您将被放入/ home /deploy (这是您的主目录)。

应用程序的Git副本位于app上的/data/APPNAME/shared/cache-copy/中

您可以在一个实例上拥有多个应用程序，每个应用程序都可以有不同的部署密钥，因此您可以使用GIT_SSH包装器。

GIT_SSH=/data/APPNAME/shared/config/pulse-ssh-wrapper git pull

(在上述所有命令中，请记住将APPNAME替换为应用程序的名称)

如果您想要找到捆绑的宝石的实际位置，可以查看

/data/APPNAME/shared/bundled_gems/ruby/2.0.0/gems (版本将取决于Ruby )

如果您的Gemfile使用:git，请记住，只有一个部署键可以用于应用程序克隆和绑定阶段，您不能在每个gem中选择不同的键。

最有可能的问题是安装nmatrix gem的问题是ATLAS库尚未安装，而这些库将与系统的包管理器一起安装(针对Gentoo和Apt用于Ubuntu)。您可以通过用户界面上的“编辑Unix软件包”添加它们，只需选择sci-libs/blas-atlas和sci-libs/lapack atlas。目前，这将失败，因为EC2实例是Xeon处理器，库还没有在这些基础上构建。

您可以在Linux实例上看到带有"cat /proc/cpuinfo“的CPU类型，并将看到以下内容

model name  :Intel(R) Xeon(R) CPU E5-2650 0 @ 2.00GHz
