ruby - AWS Codedeploy 在安装期间失败 : UnknownError "\xCC" from ASCII-8BIT to UTF-8

Question

我已尝试对 Amazon Linux EC2 实例上的 CodeDeploy 代理返回的未知错误进行故障排除。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。

我在 EC2 实例上编辑了/etc/codedeploy-agent/conf/codedeployagent.yml 并将 :verbose: 设置为 true。我尝试再次部署并在/var/log/aws/codedeploy-agent 打开 codedeploy-agent.log。

失败前日志中的最后几行显示代理 installs ELB scripts provided by AWS .

最后安装的文件不相关。因为我也曾尝试删除上面提到的脚本。该错误似乎与上游和 Ruby 相关。

我试过 $ grep --color -in -r '\xCC'/my/folder/ 返回类似的东西

二进制文件/my/folder/a.png 匹配

但也返回了/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。

I have also updated several gems according to a couple of StackOverflow threads .

我该如何减轻这个错误？我发现来自 Amazon CodeDeploy 的错误消息含糊不清且难以排除故障，而且我已经没有想法了。

Answer 1

问题看起来是在安装/启动 CodeDeploy 时尚未设置 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。

可以通过运行查看codedploy进程的LANG env

ps auxe |grep codede

我们通过 puppet 部署 CodeDeploy，并且在运行安装脚本时必须设置 (environment => 'LANG=en_US.UTF-8')。
