我正在运行虚拟服务器在网络上Ubuntu 12.04 LTS / 32 位.
全新安装后JRE 7和Tomcat 7，按照说明http://www.sysadminslife.com，我没有启动并运行 Tomcat 7。
> java -version
java version "1.7.0_09"
Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
Java HotSpot(TM) Client VM (build 23.5-b02, mixed mode)
> /etc/init.d/tomcat start

netstat 有时会显示 Java 进程，但大多数时候不会。如果显示，则什么也不起作用。
有谁有解决方案或遇到过类似的情况吗？
以下是catalina.out：

答案1
这安装以上是正确的，感谢@Fuzzyfelt 的验证。
在尝试了其他 Java 版本多次失败后，我放弃了，并（再次）在网上搜索提示。最后，我偶然发现了这篇文章
http://orange-coding.net/2012/08/10/strato-vserver-ubunut-12-04java/
Strato (strato.de) 的虚拟化软件在运行带有 Java 的 Ubuntu 12.04 LTS 时出现错误。
今天切换到 Ubuntu 10.04 LTS，一切都很好！
我会把这篇文章留在这里，除非有人给我一个合理的理由删除它。就我而言，网络上应该有更多资源指出 Ubuntu 12.04 LTS 和 Strato 上的 Java 存在的问题。
