Ruby 应用程序 onetimesecret 无法从 systemd 单元启动

我正在尝试按照此手册在 CentOS 7.4.1708 (Core) 上安装 ruby​​ 应用程序 onetimesecret：https://github.com/onetimesecret/onetimesecret。Ruby 与 rvm 一起安装。

从 shell 运行此命令时一切正常：

/usr/local/rvm/rubies/ruby-2.3.8/bin/bundle exec thin -e dev -R config.ru -p 7143 -P /var/run/onetime/onetime.pid -l /var/log/onetime/onetime.log -d start

服务器启动并运行。

但它不适用于 systemd 单元。

答案1

您应该使用 RVM 为您提供的包装器直接调用 thin。否则，系统最终可能会运行错误的 ruby​​，这确实发生了。

例如：

ExecStart=/usr/bin/bash /usr/local/rvm/wrappers/%i/thin start <your options>

我已经在 Google 上搜索到了正确答案：https://mikewilliamson.wordpress.com/2015/08/26/running-a-rails-app-with-systemd-and-liking-it/

因此，我必须将“/usr/bin/bash -lc”添加到 ExecStart 中的命令中。它将是：

ExecStart = /usr/bin/bash -lc '/usr/local/rvm/rubies/ruby-2.3.8/bin/bundle exec thin -e dev -R config.ru -p 7143 -P /var/run/onetime/onetime.pid -l /var/log/onetime/onetime.log -d start'
