在 VPS/Burstnet 上安装运行 Tomcat

启动 JVM 的最低内存要求是多少？我有最便宜的VPS Burstnet（512mb内存）并安装了java。当我输入 java 时，它显示

$java
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

当我输入 top 时，仍有大约 400MB 可用内存。

支持人员告诉我唯一的解决方案是增加我的记忆力，我怀疑他的建议。如果是内存不足引起的，我尝试创建交换文件，但是由于我的 VPS 运行在 OpenVS 上，所以不允许交换文件，而 OpenVs 不允许交换文件。 http://writereadspread.blogspot.com/2010/08/swap- on-vpsopenvs.html

如果您能回答以下任何问题，我将不胜感激：

问题的原因是什么？
安装 JRE 和 JDK 的最低内存要求是多少？
如果您在 VPS 上运行 Java 应用程序，您的内存是多少？您使用的是哪台主机？

原文

What is the minimum memory requirement to start JVM?
I have the cheapest VPS Burstnet (512mb memory) and installed java.
When I type java, it says

$java
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

When I type top, there is still around around 400MB free memory.

The support tells me the only solution is to increase my memory, I doubt his suggestion. In case it is caused by insufficient memory,I tried to create a swap file, however swap file is not allowed due to my VPS runs on OpenVS, and OpenVs does not allow swap files. http://writereadspread.blogspot.com/2010/08/swap-on-vpsopenvs.html

I would be very much appreciated if you can answer any of the following questions:

What is the cause of the issue?
What is the minimum memory requirement for installing JRE and JDK?
If u r running java apps on VPS, what is your memory, and which host r u using?

在 VPS 上运行 Tomcat：
* 如果安装了 openjkd，请卸载
* 安装sun-java Linux安装
* 安装tomcat
* 运行export JAVA_OPTS="-XX:MaxPermSize=64m -Xms16M -Xmx64m"
* 启动Tomcat ./startup.sh
