张宴的博客

新手想学习服务器的相关知识，先从张老师的博客起步，哈。

你好，张老师，今天刚注册，想咨询个问题。刚接触APMServ5.2.6，我的网站根目录下访问没有问题，但我要在本机设置多个虚拟目录，同时可以测试多个网站。这个虚拟目录如何设置，我搞了好久都没有搞定！我的QQ号是89076648，方便请为我解答一下，谢谢！

Win版适合做服务器吗

张老师 您好，想跟你谈一下关于搜索引擎相关的技术与业务，相信会有很不错的收益！

联系QQ 854854   麻烦您加我QQ沟通一下 ，谢谢了！

张老师，您好！
APMServ5.2.6在Windows server 2003运行一段时间后出现这个问题，是什么原因，谢谢~
Zend Optimizer not installed
This file was encoded by the Zend Encoder / Zend SafeGuard Suite

In order to run it, please install the freely available Zend Optimizer, version 2.1.0 or later.

What is the Zend Optimizer?
The Zend Optimizer is one of the most popular PHP plugins for performance-improvement, and has been freely available since the early days of PHP 4. It improves performance by taking PHP's intermediate code through multiple Optimization Passes, which replace inefficient code patterns with efficient code blocks. The replacement code blocks perform exactly the same operations as the original code, only faster.

In addition to performance-improvement, the Zend Optimizer also enables PHP to transparently load files encoded by the Zend Encoder or Zend SafeGuard Suite.

The Zend Optimizer is a freely-available product from Zend Technologies. Zend Technologies is the company that develops the scripting engine of PHP, also known as the Zend Engine.

大家别乱说了，张工也要挣钱。apmserv晚推出也没什么？必竟人家是义务的，有必要对某些人负责吗？

然后 在另一台机器上用 ab -n 50000 -c 500 http://moodle.tf-swufe.net/ 来压，服务器无所应，且top如图：

请教如何优化。。。，谢谢！

对于原来使用apache的如何无损平移这个最为重要。不管是用什么web server。apache也好，nginx也罢。关键是升级后如何过渡。因为还要涉及到伪静态问题，apache下面的和nginx下面肯定不一样的
