CentOS 升級後 Ruby/Mongrel 安裝中斷，伺服器無法啟動

我認為我之前的問題表述得有些糟糕。

我遇到了一個執行 ruby​​ 的 CentOS 系統和一個在作業系統更新後失敗的混合伺服器的問題。

編輯：最初的問題已經消失。但是啟動伺服器仍然無法正常工作：

./script/server

Rails 2.2.2 是應用程序所要求的。我知道它已經過時了，但現在我只想讓那個東西再次執行，然後再為升級而煩惱。

嘗試安裝 mongrel 如下所示：

gem install mongrel

Mongrel 與 Ruby > 1.9.1 不兼容，並且也不再維護。你真的不應該使用它。

您的選擇是：

1. 切換到另一台伺服器。Thin 是通常推薦的繼任者，因為它基於 mongrel。（可能是您最好的選擇。）
2. 使用變通方法強制 Mongrel 進行編譯。不過，這並不能保證它會真正起作用……
