张老师，您好！
APMServ5.2.6部署出现这个问题？
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

张老师，我是刚刚接触到linux，想自己搭一台服务器，做测试使用，但总是搭不起来，到处都是问题，就拿装mysql来说，按照您介绍的方法，有时候安装成功，并且使用正常，但有时候就出现问题，或者编译，或者安装，好像linux版本不一样的原因，我也弄不明白，总是出现问题，一直很困扰，希望您给我指导一下

是用APMServ还是Nginx问题不大，问题是怎么让我们这些用您的APMServ 5.2.6老用户平滑升级才是最重要的，我们的网站现在在你APMServ 5.2.6搭建的服务器上，改用新版本后会不会出现很多无知问题啊？？希望张老师好好考虑一下啊！

Apache  用惯了 没了他害怕不习惯

您好！请问“大侠”我是昨天安装了您的08年开发的软件APMServ2.5.6的软件但是我用不了我解压了还有打开了放了网站的文件去了按“本地访问站点”但是我的电脑上登录不了您所说的127.0.0.1打开不了，我也查过网友的资料看了也操作过来还是不成功。请问大侠我应该是要怎么做好呢？我安装的系统是WINXPSP3的请大侠指点下！
