AWS Codedeploy 在安装期间失败：从 ASCII-8BIT 到 UTF-8 的未知错误"xCC"

Question

我尝试对 Amazon Linux EC2 实例上的 CodeDeploy 代理返回的 UnknownError 进行故障排除。我将文件从 Mac 上的本地 git 存储库推送到 S3 存储桶，然后从那里部署到 EC2 实例。

我已经编辑了/etc/codedeploy-agent/conf/codedeployagent.yml 并在 EC2 实例上将 ：verbose： 设置为 true。我尝试再次部署并打开 codedeploy-agent.log 在/var/log/aws/codedeploy-agent。

失败前日志中的最后一行显示代理安装了 AWS 提供的 ELB 脚本。

最后安装的文件不相关。因为我也试图删除我上面提到的脚本。该错误似乎是上游的，与 Ruby 相关。

我已经尝试过$ grep --color -in -r 'xCC' /my/folder/它返回类似的东西

Binary file /my/folder/a.png matches

但也回来了/my/folder/wp-content/plugins/wordpress-seo/admin/class-metabox.php:348:'Ì'

所以我删除了插件并尝试使用 convmv 将文件名从 ASCII 转换为 UTF-8（它没有转换任何东西）。但没有成功。

我还根据几个 StackOverflow 线程更新了几个 gem。

如何缓解此错误？我发现来自 Amazon CodeDeploy 的错误消息很糟糕，很难进行故障排除，而且我已经没有想法了。

Answer 1

问题似乎是在安装/启动代码部署时未设置LANG env。

我发现，如果我通过 CLI 重新启动 CodeDeploy，那么应用程序将毫无问题地部署。

您可以通过运行以下命令检查编码进程的 LANG 环境

ps auxe |grep codede

我们通过 puppet 部署 CodeDeploy，并且必须设置 （environment => 'LANG=en_US。UTF-8'） 运行时运行安装脚本。

Answer 2

尝试更新代码部署代理。它对我有用。通过 SSH 连接到您的实例并运行以下命令： sudo /opt/codedeploy-agent/bin/install auto

Answer 3

必须在部署开始时定义 LANG 环境变量，否则 CodeDeploy 安装事件将失败。

您可以通过编辑 CodeDeploy 代理服务配置来确保 CodeDeploy 具有它：

sudo vim /etc/init.d/codedeploy-agent

您可以在服务首次启动时导出变量，并带有以下行：export LANG="en_US.UTF-8" 。

因此，起始块将如下所示：

start() {
  echo -n $"Starting $prog:"
  export LANG="en_US.UTF-8"
  cd $AGENT_ROOT
  nohup $BIN start >/dev/null </dev/null 2>&1  # Try to start the server
  exit $?
}

一些附加说明

对我来说，问题只发生在自动缩放事件期间。换句话说，我可以手动启动实例，然后部署得很好，但在启动新实例时就不对了。 这表示一种争用条件，即服务启动后环境尚未准备就绪。我尝试通过运行来更改新贵时间：

update-rc.d -f codedeploy-agent remove
update-rc.d codedeploy-agent start 99 2 3 4 5 . stop 20 0 1 6 . 

但这没有奏效。在起始块中设置变量可以保证它及时可用。

为了确保您在 CodeDeploy 启动后立即拥有所有必需的环境变量，遵循 Amazon 的建议可能是明智的：

我们建议您使代理服务保持停止状态，并使用启动脚本启动代理服务
