Centos环境下安装Zend optimizer 3.3.9的方法
<p>本文实例讲述了Centos环境下安装Zend optimizer 3.3.9的方法。分享给大家供大家参考，具体如下：</p>
<p>
<strong>1、下载文件：</strong></p>
<p>
http://downloads.zend.com/optimizer/3.3.9/ZendOptimizer-3.3.9-linux-glibc23-i386.tar.gz （32位）</p>
<p>
http://downloads.zend.com/optimizer/3.3.9/ZendOptimizer-3.3.9-linux-glibc23-x86_64.tar.gz （64位）</p>
<p>
<strong>2、解压</strong></p>
<p>
解压后把ZendOptimizer-3.3.9-linux-glibc23-x86_64/data/5_1_x_comp目录下的ZendOptimizer.so拷贝到某一个目录，比如/usr/local/Zend/lib/</p>
<p>
Zend optimizer 3.3.9有一些新的改动，不需要安装了，直接在php.ini文件里面引用.so文件即可：</p>
<p>
<strong>3、修改/etc/php.ini文件</strong></p>
<p>
找到：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_121330">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">zend.ze1_compatibility_mode = Off</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
修改为：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_633274">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">zend.ze1_compatibility_mode = On</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
在末尾加上以下文字：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_953308">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
<div class="line number3 index2 alt2">
3</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain"></code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">zend_optimizer.optimization_level=1</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash plain">zend_extension=</code><code class="bash string">"/usr/local/Zend/lib/ZendOptimizer.so"</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
<strong>4、重启httpd服务，通过</strong><code>php -v</code> <strong>可以看效果。</strong></p>
<p>
PS：这样装完以后显示ZendOptimizer为3.3.3，难道3.3.9中对php5.1.6的支持还停留在3.3.3吗？</p>
<p>
希望本文所述对大家CentOS服务器配置有所帮助。</p>
