我在 Ubunto 12.10 上启动乘客 — rvmsudo passenger start -p 80 --user=support，并收到此错误：

我做错了什么，也许这是许可？

【解决方案1】：

1024以下的端口只能打开，虽然你可以使用iptables重定向流量：

# iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 3000

由于环回设备（如localhost）不使用prerouting规则，如果需要使用localhost等，也添加这条规则：

# iptables -t nat -I OUTPUT -p tcp -d 127.0.0.1 --dport 80 -j REDIRECT --to-ports 3000

或者你可以在apache http server或者nginx下使用passener，并使用它们的configs来设置应用程序。

【解决方案2】：

实际上，这是 Phusion Passenger 中的一个错误。命令 rvmsudo passenger start -p 80 --user=support 应该可以正常工作，而无需 Paulo 建议的 iptables 更改。我已经修复了这个错误，这个错误修复将成为 Phusion Passenger 4.0.15 的一部分。
