我search了几天，收集了所有的优化build议，并尝试。
我的网站没有得到任何高点击。
可能会像每天100次点击[所有我的网站加起来]。
我有512MB的RAM VPS与1024 MB的突发。
Centos 5 32-bit & cPanel/WHM Apache 2.2 MySQL 5.0 PHP 5.3.2 我有2个WordPressMU生产网站和1个testing网站
我使用my-medium.cnf样本开始

我没有select很多模块，并在WHM中使用EasyApache进行了重新编译。
只有build立了以下模块
Deflate Expires Fileprotect Imagemap MPM Prefork Version [default] EAccelerator for PHP Bcmath Calendar CurlSSL [I'm using Curl. But I don't have any https sites] Expat GD [for image cropping] Gettext Imap Mbregex [default] Mbstring [need both Mbregex and Mbstring for utf-8] Mysql of the system MySQL "Improved" extension. Sockets TTF (FreeType) [I'm using custom font] Zlib
在全局configuration下
I only have FollowSymLinks enabled I Have TraceEnable, ServerSignature, FileETag OFF ServerTokens ProductOnly DirectoryIndex Priority has index.php as the first one
我已经删除了Clamd [Clam Anti-virus]
SpamAssasinclosures
在调整设置下
Default catch-all/default address behavior for new accounts. This is set to "fail" All stats programs turned off
我安装了eAccelerator并在phpinfo中检查了它的工作
[预先包含在WHM下的VirtualHost]
Timeout 20 KeepAlive On MaxKeepAliveRequests 200 KeepAliveTimeout 3 MinSpareServers 1 MaxSpareServers 3 StartServers 1 ServerLimit 50 MaxClients 50 MaxRequestsPerChild 4000 ExtendedStatus Off #ServerType standalone this throws error HostnameLookups Off <Directory "/"> AllowOverride None </Directory>
我的网站将需要很长时间才能加载，WHM / CPanel甚至不会加载。

我的平均内存消耗就像1000 MB！ [是总是爆裂]
消耗大多数CPU和大多数内存的进程是mysql
但是我也得到了15个httpd进程[当它的爆发]
我已经从cpuwatchcheck警告说
“在处理过程中，cpu已经超过了6个小时的时间，这封电子邮件在服务器上的当前负载/正常运行时间是07:00:37上午11:30，0个用户，平均负载： 14.64，16.79，20.07“
我不知道，我试过很多不同的时间切换这些configuration值，但似乎没有任何工作。
请展示一些光线…谢谢
这是当RAM是800MB时显示mysql的进程列表
当RAM大约为800 MB时，这里是当前从WHM运行的进程

我想知道是否有什么有趣的东西出现在您的日志文件（也许在/ var / log / httpd？
它几乎看起来像你把东西从.htaccess中移出到一个/ etc / httpd / conf文件中，这可以帮助保持apache免受.htaccess文件的目录。
你能通过ssh或腻子以某种方式login，并得到一个命令shell，你可以运行顶部？
一个演出是less量的记忆，但我运行约5 wpmu网站和256meg下的一个tikiwiki网站与一些玩PHPCake和Ruby on Rails。 我正在考虑移动一些我也有的Drupal站点，但是我的内存有点低。
我也有一个APCcaching，但我严格用于代码caching，并保持页面和对象caching在磁盘上，虽然我使用W3总caching为我的WPMU网站，而不是超级caching，我也发现是相当不错的。
我没有在我的VPS系统上使用任何面板。 我喜欢直接在Linux上工作的自由。 我正在运行我的电子邮件服务器的exim，并为pop3做了一些事情。 我想要设置Python和Tomcat以及我有一种MVC统一types的想法，我想看看这是否是一个有潜力的想法。
无论如何，我的wpmu网站很小，但我的VPS只有你们显然拥有的四分之一。 想想看，在系统启动时我注意到的第一件事情之一就是在DNS之前我有脚本小子和垃圾邮件机器人打我的VPS！ 还有一些人正在做一些暴力攻击，所以我build立了一些入侵检测系统，并把它们放到防火墙里几天，其他的则永久性的。 我还通过apache和wordpress插件安装了很多安全措施，以消除sql插入和垃圾。
我不知道你是否通过SSL打开了50条Apache线，但是我注意到你提到了大概有15个并发连接？
运行top，ps，vmstat，iostat或者其他任何你可能得到的东西，都可以让你知道瓶颈在哪里。 你的分页或扫描速度很重吗？ 你有很多可运行的程序吗？ 什么是CPU负载？ 如果你每时每刻都在压缩和encryption数十亿次的东西，那么你的CPU负载很容易通过平stream层。
或者，也许您的网页之一，在Digg上stream行？ 抱歉。 现在已经很晚了，我可能应该睡一会儿，因为我到处游荡，我不知道我是否正在打击任何可能会给你任何有价值的想法….
最好的问候，丹
