我想将端口 8080 更改为默认 HTTP 端口 (80)，以将 Jersey 应用程序用作 HTTP-Restful API。因此，我将端口从 8080 替换为 80（在 内/etc/tomcat7/server.xml），并将其配置为使用 AUTHBIND ( /etc/defaults/tomcat7)。重新启动服务后，我在 中发现了这个奇怪的错误/var/log/tomcat7/catalina.out。
有人能翻译一下这个错误吗？为什么 tomcat 无法创建套接字？
我正在使用 ubuntu 14.04 和 tomcat7。

我找到了一个可行的解决方案：
sudo touch /etc/authbind/byport/80
sudo chmod 500 /etc/authbind/byport/80
sudo chown tomcat7 /etc/authbind/byport/80
