CentOS上搭建PHP服务器环境的步骤与方法
<p>本文实例讲述了CentOS上搭建PHP服务器环境的步骤与方法。分享给大家供大家参考，具体如下：</p>
<p>
<strong>安装apache:</strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_454505">
<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">yum </code><code class="bash functions">install</code> <code class="bash plain">httpd httpd-devel</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>启动apache:</strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_771750">
<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">/etc/init</code><code class="bash plain">.d</code><code class="bash plain">/httpd</code> <code class="bash plain">start</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
此时输入服务器的IP地址，应该看到apache的服务页面，端口不用输，apache默认就是使用80端口</p>
<p>
<strong>安装mysql:</strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_970094">
<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">yum </code><code class="bash functions">install</code> <code class="bash plain">mysql mysql-server</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>启动mysql:</strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_157143">
<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">/etc/init</code><code class="bash plain">.d</code><code class="bash plain">/mysqld</code> <code class="bash plain">start</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>安装php</strong></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_562361">
<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">yum </code><code class="bash functions">install</code> <code class="bash plain">php php-devel</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
<span>重启apache使php生效</span></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_375090">
<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">/etc/init</code><code class="bash plain">.d</code><code class="bash plain">/httpd</code> <code class="bash plain">restart</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
此时可以在目录：/var/www/html/下建立一个PHP文件</p>
<p>
代码：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterphp" id="highlighter_750327">
<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="php plain"><?php phpinfo(); ?></code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
然后访问这个文件，就能看到PHP的一些信息，php.ini配置文件的路径可以在这个页面上看到</p>
<p>
<strong>安装php的扩展</strong></p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code82204">
yum install php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc</div>
<p>
<br><span>安装完扩展之后需要再次重启apache</span></p>
<p>
</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_909536">
<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">/etc/init</code><code class="bash plain">.d</code><code class="bash plain">/httpd</code> <code class="bash plain">restart</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>

可以把上面的代码传入目录/var/www/html/</p>
<p>
就可以看到执行情况</p>
<p>
<strong>PS：</strong>简单的搭建方法还可使用如EZHTTP工具进行一键部署。感兴趣的朋友可参考相关文档，这里不再讲述。</p>

希望本文所述对大家CentOS服务器配置有所帮助。</p>
