我正在尝试在我的Web服务器上将Thin作为服务运行。在运行“sudo thin install”后,Thin在/etc/init.d/thin中创建了以下文件。
#!/bin/sh
DAEMON=/usr/local/lib/ruby/gems/1.9.1/bin/thin
SCRIPT_NAME=/etc/init.d/thin
CONFIG_PATH=/etc/thin
# Exit if the package is not installed
[ -x "$DAEMON" ] || exit 0
case "$1" in
start)
$DAEMON start --all $CONFIG_PATH
;;
stop)
$DAEMON stop --all $CONFIG_PATH
;;
restart)
$DAEMON restart --all $CONFIG_PATH
;;
*)
echo "Usage: $SCRIPT_NAME {start|stop|restart}" >&2
exit 3
;;
esac
当thin服务启动时,会运行以下命令:
thin start --all /etc/thin该命令将扫描所有定义如何运行thin的yaml配置文件。然而,这种方法并不起作用。
我在日志中看到了以下内容:

当Capistrano部署时,我将bundle缓存在$APP_PATH/shared/bundle目录中; 所以,这就解释了为什么thin抱怨没有安装gems,因为thin服务不会查找$APP_PATH/shared/bundle。
这样做是可以的:
cd $APP_PATH/current; bundle exec thin start -d -C /etc/thin/app_x.yml
但是这不是位于 /etc/init.d/thin 的薄服务文件的工作方式。我猜我可以自己编写,只是我不想解决已经解决过的问题。
