blocks|key|4604952|text|这取决于你的应用程序。您可能需要考虑使用相同的操作系统和分配的内存量来运行VMWare映像，将大约10个小型网站部署到该映像中，并对模拟您预期的大致流量的图像进行压力测试。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|entityMap^0^^$0|@$1|2|3|4|5|6|7|C|8|@]|9|@]|A|$]]]|B|$]]

That really depends on your applications. You might want to consider running a VMWare image with the same OS and amount of memory allocated, deploying your 10 or so small websites to that image, and running a stress test against the image that emulates the approximate traffic you expect.

blocks|key|4604851|text|为什么不对这些站点在本地运行一些测试，并测量它们的内存使用情况呢？如果不知道你的网站到底在做什么，就很难不这么说。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|entityMap^0^^$0|@$1|2|3|4|5|6|7|C|8|@]|9|@]|A|$]]]|B|$]]

Why not run some tests locally with those sites, and measure their memory usage? It's too hard to say otherwise, without knowing exactly what your sites are doing.

blocks|key|863936|text|我目前正在工作中运行多个am。使用256+on，我可以轻松地使用PHP在CentOS上运行Apache。所以，你应该可以用384兆处理它。不幸的是，如果在增加内存之前无法在上面运行java/Tomcat。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|863937|取决于所使用的VPS技术。如果提供程序使用OpenVZ/VServer，您将能够从运行Linux内核中节省几十MB的内存。但是，如果它使用类似于Xen的东西，则需要在Linux内核上花费一些内存。|863938|如果您不需要使用Apache，请避免使用它。周围还有很多其他轻量级的网络服务器。你已经提到过了。您也可以尝试lighttpd，我认为许多RoR站点都使用它。|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|G|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|H|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|I|8|@]|9|@]|A|$]]]|F|$]]

I am presently running multiple VMs at work. With 256Mb I can comfortably run Apache on CentOS with PHP. So, you should be able to handle it with 384Mb. Unfortunately, if I am not able to run java/Tomcat on it until I increase the memory.

Depends on the kind of VPS technology used. If the provider uses OpenVZ/VServer, you will be able to save several tens of MB of memory from running the Linux kernel. However, if it uses something like Xen, you will need to spend some memory on the Linux kernel.

If you do not need to use Apache, avoid using it. There are plenty of other light-weight web servers around. You have already mentioned nginx. You can also try lighttpd and I think that many RoR sites use it.

blocks|key|4605048|text|您不可能从该配置中获得可接受的性能。在您开始查看Apache和(特别是)+MySQL之前，这4个Rails应用程序将占用更多的内存。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|entityMap^0^^$0|@$1|2|3|4|5|6|7|C|8|@]|9|@]|A|$]]]|B|$]]

There's no way you're going to be able to get acceptable performance out of that configuration. The 4 Rails apps will take more memory than that on their own, before you start looking at Apache and (especially) MySQL.

blocks|key|864087|text|我强烈建议您不要安装cPanel。仅仅是cPanel本身可能会消耗比其他所有东西加起来更多的内存。手动配置一个小型VPS并不太困难，也不费时，特别是如果您使用Google应用程序来承载您的电子邮件并使用您的注册服务器。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|entityMap^0^^$0|@$1|2|3|4|5|6|7|C|8|@]|9|@]|A|$]]]|B|$]]

I strongly suggest that you don't install cPanel. Just cPanel alone will probably eat more memory than everything else combined. Manually configuring a small VPS isn't really too hard or time-consuming, especially if you use Google Apps to host your email and use your registrar's name servers.

blocks|key|863854|text|你可以租一个月的VPS，看看它有多好。许多提供者将允许您将VM升级到更昂贵的计划。(例如，我知道林诺德让这件事变得很容易。)|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|863855|我预计384+MB将仅仅是勉强足够。这可能会奏效，但为了安全起见，你也可能需要更多的空间。|entityMap|0|LINK|mutability|MUTABLE|url|http://linode.com/^0|1C|3|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@$A|N|B|O|1|P]]|C|$]]|$1|D|3|E|5|6|7|Q|8|@]|9|@]|C|$]]]|F|$G|$5|H|I|J|C|$K|L]]]]

You could just rent the VPS for a month and see how well it works. Many providers will let you upgrade your VM to a more expensive plan. (I know <a href="http://linode.com" rel="nofollow noreferrer">Linode</a> makes this easy, for example.)

I expect that 384 MB will be just barely sufficient. It might work, but you might also want a little more headroom for safety's sake.

blocks|key|4605068|text|内存越多，交换的次数就越少，也就是说磁盘上的I/O越少--也就是说，less+%2B+apache+%2B+mysql本身就更快了，但是一旦应用程序启动并运行，它可能很快就会耗尽内存……今天的记忆很便宜，所以我建议多加一点。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|entityMap^0^^$0|@$1|2|3|4|5|6|7|C|8|@]|9|@]|A|$]]]|B|$]]

the more memory you'll give the less it'll swap i.e. less I/O on disk i.e. faster, centos + apache + mysql by itself, but once you have your apps up and running it might run out of memory very quickly... today memory is very inexpensive so i suggest to bump it up more

blocks|key|864035|text|384+MB是一个不错的起点。但是，如果您不使用cPanel，您可能会得到更好的结果--它启动了许多在单个用户VPS上不需要的进程，这些进程将占用大量内存。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|entityMap^0^^$0|@$1|2|3|4|5|6|7|C|8|@]|9|@]|A|$]]]|B|$]]

384 MB is a decent starting point. You may get better results if you don't use cPanel, though -- it starts a number of processes which aren't necessary on a single-user VPS and which will use up a significant amount of memory.

I'm considering to rent a VPS with 384 MB memory. It would run on CentOS and would have cPanel with Apache 2 / MySQL and Phusion Passenger with nginx / sqlite.

What do you think, will it have enough memory? It would serve around 10 small traffic PHP/MySQL websites and 3-4 small traffic Ruby on Rails app.

Thanks for your suggestions.

384 MB enough for a starter VPS?

我正在考虑租一个384 MB内存的VPS。它将在CentOS上运行，cPanel与Apache 2/ MySQL和Phusion乘客使用nginx / sqlite。你觉得它有足够的记忆吗？它将服务大约10个小流量PHP/MySQL网站和3-4小流量Rails应用程序。谢谢你的建议。
