启用非root用户以使用端口443运行tomcat

Question

我正在尝试使用https作为非root用户运行tomcat。配置server.xml并进行必要的端口修改并添加SSL配置。

但是当我在catalina.out

中执行sudo systemctl restart tomcat时出现以下错误

 org.apache.coyote.AbstractProtocol.init Failed to initialize end point associated with ProtocolHandler ["https-jsse-nio-443"]
      java.net.SocketException: Permission denied
