无法绑定到：/0.0.0.0:443

我在端口 443 上启动 Play 框架服务器时遇到问题，我使用的是 scala play 2.20，我的 Play 服务器在端口 9443 上按照以下命令正常运行

./start -Dhttps.port=9443 -Dhttps.keyStore=/home/ubuntu/ssl/tomcat.keystore -Dhttps.keyStorePassword=mypasswd

但是当我想通过以下命令在端口 443 上运行播放服务器时

./start -Dhttps.port=9443 -Dhttps.keyStore=/home/ubuntu/ssl/tomcat.keystore -Dhttps.keyStorePassword=mypasswd

它给了我错误

答案1

原因：java.net.SocketException：权限被拒绝

您需要以 root 身份（超级用户）才能绑定到 1024 以下的端口。这就是 9443 可以工作而 443 不工作的原因。
