我在 nginx/passenger 上运行了一个 Rails 应用。它使用 顺利地在 shell 中重新启动sudo /etc/init.d/nginx stop|start|restart
。但是 Passenger 在系统重新启动时抛出一个错误:“缺少 Rails #{version} gem”。但是GEM_HOME
和GEM_PATH
都已设置,/etc/environment
所以它们在重新启动期间肯定可供所有进程使用?

在 Ubuntu Maverick 上,在运行 init 脚本之前,我没有看到任何可以读取 /etc/environment 的内容。最好的办法是创建一个名为 /etc/default/nginx 的文件(如果该文件尚不存在),然后将环境文件中的三行放入其中。
