我有一个带J2EE的Web应用程序项目，我想用apache tomcat在端口80上运行我的web应用程序，我给出了这个错误：
4:31:34 PM运行错误测试：地址localhost：80已在使用中 4:31:37 PM运行错误测试：无法打开调试器端口：java.net.SocketException＆＃34; Socket closed＆＃34;
我使用此命令显示所有进程

我认为osx或etc中的另一个进程是从端口80使用的。 有什么想法吗？
答案 0 :(得分：0)
尝试$ sudo lsof -Pn -i | grep ":80 (LISTEN)"
我希望你会得到像

表示：您的mac Web服务正在运行。 如果您使用的是Mountain Lion或更新版本，我也希望您通过sharing dialog在较旧的操作系统版本中启用它。不幸Apple removed this setting但没有禁用该服务......这就是它对我的看法。也许它已经通过timeMachine恢复在后台重置
