教你一步一步在linux中正确的安装Xcache加速php
<p>首先，强烈吐槽，百度上的教程，都左复制右复制的，乱七八糟，缺东缺西的。借此微凉大大我提供我苦心整理好的教程。以便各位小菜能顺利的使用Xcache加速php，如果看完了，也操作了，还是失败了的话，请联系微凉大大的QQ 496928838，微凉大大也想看看你是如何一步一步都装不上。</p>

#第三步，非常重要，基本出错都在这里。<br>
#首先，安装前要执行phpize配置</p>
<p>
/php的路径/bin/phpize</p>
<p>
#请确保已经安装了php，如果没有安装php请先安装php。（费话，你不装php，装什么Xcache啊）</p>
<p>
#接下来，配置->编译->安装，可一步到位，前提是你路径没有错误。</p>

#当然，如果你很笨的话。用不起这个命令。那么，在解压好的源码目录中，直接通过FTP之类的工具，直接移动也是OK的。</p>

配置php.ini，<br>
还是在源码目录中，找到 xcache.ini ， 然后直接在 php.ini 后面加就行。<br>

看看phpinfo中是否有Xcache。有就证明安装成功了。</p>
<p>
如果配置完成后，页面都打不开了。证明你php.ini中冲突了。</p>
<p>
例如 zend optimizer，这个东西就会冲突。解决方法就是把 zend_extension 改成 Xcache定义的缓存文件中。</p>
