【问题描述】：
在关注this Gist 之后，我正在尝试使用 Travis 将 Rails 应用程序部署到 VPS，但遇到了一些问题。我在我的服务器上生成加密的 ssh 密钥，如下所示：
base64 --wrap=0 ~/.ssh/id_rsa > ~/.ssh/id_rsa_base64
ENCRYPTION_FILTER="echo \$(echo \"-\")\$(travis encrypt theodi/uk-postcodes \"\$FILE='\`cat $FILE\`'\" | grep secure:)"
split --bytes=100 --numeric-suffixes --suffix-length=2 --filter="$ENCRYPTION_FILTER" ~/.ssh/id_rsa_base64 id_rsa_
然后，我将生成的加密变量放入我的 .travis.yml 文件中，并将重构后的私钥 before_install 放入，如下所示：
before_install:
- echo -n $id_rsa_{00..30} >> ~/.ssh/id_rsa_base64
- base64 --decode --ignore-garbage ~/.ssh/id_rsa_base64 > ~/.ssh/id_rsa
- chmod 600 ~/.ssh/id_rsa
- echo -e "Host github.com\n\tStrictHostKeyChecking no\n" >> ~/.ssh/config
在像这样成功构建之后，我正在运行cap production deploy：
after_success:
- "[ \"$TRAVIS_BRANCH\" == \"master\" ] && bundle exec cap production deploy"
但我仍然没有快乐。我在 Travis 输出（来自 Capistrano）上得到的错误如下：
INFO [5a729430] Running /usr/bin/env mkdir -p /tmp/uk-postcodes/ on 162.243.77.171
DEBUG [5a729430] Command: ( RAILS_ENV=production /usr/bin/env mkdir -p /tmp/uk-postcodes/ )

我还在我的服务器上跟踪了auth.log，我看到了错误error: key_read: uudecode。
我可能会出错的任何想法？ （第一步涉及到一定数量的货物培养，但我想我明白是怎么回事了）
【问题讨论】：
-
你生成的key，是给你的机器还是给travis机器的？
-
它们是给我的服务器的。 Travis 会为每次测试运行生成小框，因此无法进行正常的公钥/私钥身份验证。
