將 Glassfish http-listener 配置到埠 443/ 80
我想在 Linux 下的 Glassfish 3.1.2.2 Build 5 中配置 http-listeners。我將 http-listener-1 的設置更改為埠 80，將 http-listener-2 的設置更改為埠 443。目的是它們監聽這些埠，而不是預設埠 8080 和 8181。所以domain.xml 看起來像這樣：
<network-listeners> <network-listener port="80" protocol="http-listener-1" transport="tcp" name="http-listener-1" thread-pool="http-thread-pool"></network-listener> <network-listener port="443" protocol="http-listener-2" transport="tcp" name="http-listener-2" thread-pool="http-thread-pool"></network-listener> <network-listener port="4848" protocol="admin-listener" transport="tcp" name="admin-listener" thread-pool="admin-thread-pool"></network-listener> </network-listeners>我通過控制台、管理控制台和手動編輯文件進行了嘗試。結果，我無法啟動 Glassfish 並在 Ubuntu 12 和 Red Hat 6.4 下出現此錯誤：

有沒有辦法在不使用 iptables 或埠重定向的情況下達到目標？
您可能正試圖以普通使用者而不是 root 使用者身份執行此伺服器。
為了在大多數作業系統上將 TCP 偵聽器綁定到 1024 以下的埠，您必須具有 root 或同等權限。這是一項安全功能，可防止普通使用者程序佔用知名服務埠。（這些被稱為特權埠。）
這就是錯誤報告的第一行包含“權限被拒絕”的原因。
