启动Ruby瘦客户端在命令行中运行良好：
RAILS_ENV=production bundle exec thin --ssl-disable-verify -C services/private_pub/private_pub_thin.yml start
但是作为deamon启动它会返回一个错误的文件描述符：
user@app:~/app$ RAILS_ENV=production bundle exec thin -d --ssl-disable-verify -C services/private_pub/private_pub_thin.yml start

有什么想法吗？这没有任何代码更改。还没有任何东西在运行。
