Tomcat7无法在ubuntu上启动(全新安装)，权限被拒绝 [英] Tomcat7 won't start up on ubuntu (clean install), permission denied
本文介绍了Tomcat7无法在ubuntu上启动(全新安装)，权限被拒绝的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个完整的ubuntu安装(14)，并尝试运行Tomcat7.我已经通过终端安装了它，运行"sudo service tomcat7 start"命令，该命令应该启动tomcat，但是当我尝试打开:localhost:8080时，欢迎索引页面未加载，并且出现404错误(找不到文件) . 8080端口也未打开，这似乎是某种许可问题.
I have a clean ubuntu installation (14) and try to run Tomcat7. I have installed it via terminal, run the "sudo service tomcat7 start" command which should start tomcat, but when I try to open: localhost:8080, the welcome index page is not loading and I get a 404 error (file not found). The 8080 port is not opened either, it seem like some kind of permission problem.
Netstat给出以下内容(注意在启动tomcat的情况下没有监听8080)
Netstat gives the following (note there is not listening for 8080 with tomcat started)

已解决:
Solved:
8080端口未使用，为了确定，我什至尝试将其更改为8089.无论如何，还有别的东西. 我已经通过命令行删除了所有tomcat7，并手动重新安装.从Apache网站安装最新版本后，一切正常.
The 8080 port was not in use, I even tried to change it to 8089 to be sure. There was something other, anyway. I have removed all tomcat7 via command line, and reinstalled manually. After installing the latest version from the Apache website everything was ok.
可以在此处找到分步指南.
推荐答案
也许您在端口8080上运行了另一个服务，或者您的内核以某种方式关闭了该端口.尝试配置另一个端口，看看问题是否仍然存在.
Perhaps you have another service running on port 8080, or your kernel somehow has that port closed. Try configuring another port and see if the problem persists.
好的，这是可行的部分:打开终端并运行
Ok, here comes the actionable part: open a terminal and run
netstat -t | grep 8080
这应该向您显示当前正在侦听8080端口的所有内容.由于Ubuntu并未立即激活防火墙，因此很可能是问题的根源.
This should show you anything currently listening on port 8080. As Ubuntu doesn't activate a firewall out of the box, this is very likely the source of the problem.
另一个最初的问题并未说明您使用的是Android.这是一条至关重要的信息，因为Android包含SELinux，该SELinux禁止在未经安全层事先同意的情况下打开端口.要允许打开端口，请在此处.
Another edit: The original question did not state that you were on Android. This is a vital piece of information, as Android includes SELinux, which forbids opening a port without prior consent from the security layer. To allow opening the port, look here.
