我正在尝试在我的 Web 服务器上作为服务运行瘦身。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
启动瘦服务时,运行以下内容
瘦启动 --all /etc/thin这将扫描所有定义如何为每个定义的应用程序运行精简的 yaml 配置文件。这不起作用。
我在日志中看到:

当 capistrano 部署时,我将我的包缓存在 $APP_PATH/shared/bundle 目录中;所以,这就解释了为什么瘦服务没有在 $APP_PATH/shared/bundle 中查找,所以为什么瘦服务会抱怨没有安装 gems
这确实有效:
cd $APP_PATH/current; bundle exec thin start -d -C /etc/thin/app_x.yml
但这不是 /etc/init.d/thin 中的瘦服务文件的工作方式。我想我可以自己写。我只是不想解决已经解决的问题。
