https://ruby-china.org/qqwerr en-us <p>本人是 Ruby 新手，想通过在 openshift 上部署 sinatra 来慢慢学习，感觉 ror 实在是繁杂故先选择了感觉轻量级的 sinatra，数据库也是了解了大概，希望大大能帮助我&gt;&lt;，下面是问题：</p> <p>我是根据<a href="http://www.danneu.com/posts/15-a-simple-blog-with-sinatra-and-active-record-some-useful-tools" rel="nofollow" target="_blank" title="">这个教程</a>在 openshift 部署个类似于这个 blog 的程序，在本地运行时无问题，但是通过 git 部署到 openshift 上后，在服务器上添加进数据库的 bolg 会在之后的 git push 后恢复为本地的测试用数据库 (即 blog.db)，后发现似乎是 push 的时候将 db 文件一并 push 到了 openshift 上，突然意识到似乎不可将数据库存放在 git 中</p> <p>之后我又尝试使用 MySQL 当做数据库，因搜索不到 sinatra 相关教程，根据了<a href="https://www.openshift.com/kb/kb-e1005-ruby-on-rails-openshift-quickstart-guide" rel="nofollow" target="_blank" title="">openshift quickstart guide</a></p> <p>依次改动/增加了</p> <pre class="highlight shell"><code>rhc cartridge add <span class="nt">-a</span> railsapp <span class="nt">-c</span> mysql-5.1 .openshift/action_hooks/deploy file config/database.yml Gemfile add gem <span class="s1">'mysql'</span> </code></pre> <p>本地运行正常但部署后还是失败了<img title=":cold_sweat:" alt="😰" src="https://twemoji.ruby-china.com/2/svg/1f630.svg" class="twemoji"> 显示为</p> <pre class="highlight shell"><code>Ruby <span class="o">(</span>Rack<span class="o">)</span> application could not be started There appears to be a database problem.
