/etc/init.d/独角兽

我在同一个 DigitalOcean Ubuntu 机器上运行我的暂存环境和生产环境。我已让所有工作正常进行，以便每个环境都可以部署到其自己的目录中，使用单独的 pid 文件运行单独的 unicorn 进程，并且 nginx 配置了单独的启用站点的文件，以将每个 unicorn 实例与其适当的环境关联起来。

我的部署过程正确地（重新）启动了匹配环境的 unicorn。问题是当我需要重新启动盒子本身时，我的盒子/etc/init.d/unicorn仅配置为启动生产环境。我不确定我需要做什么才能使生产环境和暂存环境在启动时启动，而不是创建辅助/etc/init.d/unicorn-staging文件/etc/default/unicorn-staging。

以下是我现有的文件，供参考。

您可以复制/etc/init.d/unicorn到/etc/init.d/unicorn_app2。

编辑unicorn_app2文件：

  • 变成/etc/default/unicorn​/etc/default/unicorn_app2
  • 变成/run/unicorn.pid​/run/unicorn_app2.pid

复制/etc/default/unicorn到/etc/default/unicorn_app2

编辑/etc/default/unicorn_app2以设置您的第二个应用程序

运行新服务器service unicorn_app2 start，还为第二个应用程序设置 nginx/apache（使用新的 pid 文件）
