在CentOS 6 中安装WordPress（一） 安装Apache,Mysql, PHP环境
<p>1.安装Apache<br>
<br>
在终端中输入下面的命令就可以安装Apache了：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_890334">
<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 functions">sudo</code> <code class="bash plain">yum </code><code class="bash functions">install</code> <code class="bash plain">httpd</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
sudo的意思是用root用户做什么操作。要点击y就确认下载安装了，非常方便。<br>
然后用下面的命令来启动服务</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_390468">
<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 functions">sudo</code> <code class="bash plain">service httpd 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>
现在不用着急往下弄，直接在浏览器中输入DigitalOcean给你的IP地址，应该就可以访问到Apache的欢迎页面了。类似下面的样子：</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="在CentOS 6 中安装WordPress（一） 安装Apache,Mysql, PHP环境" alt="在CentOS 6 中安装WordPress（一） 安装Apache,Mysql, PHP环境" src="https://zhuji.jb51.net/uploads/img/202305/424aec8b945a2ade58d04a05e4717b85.jpg"></p>
<p>
是不是很酷？如果你的域名已经成功解析到你主机的IP地址上的话，用你的域名应该也可以访问了！</p>
<p>
2.安装Mysql</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_958451">
<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>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">sudo</code> <code class="bash plain">yum </code><code class="bash functions">install</code> <code class="bash plain">mysql-server</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash functions">sudo</code> <code class="bash plain">service mysqld 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>
用上面的命令就可以下载安装mysql了，第二条是启动mysql服务的意思。<br>
安装mysql会询问你一些简单的配置，先按enter,后面的其实英文很简单，根据自己的需求来选。<br>
Disallow root login remotely?有这样一条选项，是否允许mysql 的root用户远程访问，我是选择了no，可以访问，这样方便些，但存在安全隐患。这样后面做软件也可以使用这个VPS中的数据库了。<br>
<br>
3.安装PHP以及PHP组件</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_76028">
<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 functions">sudo</code> <code class="bash plain">yum </code><code class="bash functions">install</code> <code class="bash plain">php php-mysql</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
用上面这个命令就可以下载安装PHP了。比较麻烦的是PHP的组件。</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_3118">
<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-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
我这里简单的安装了7个组件，你也可以搜索所有的PHP组件，用下面的命令</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_121226">
<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 search php-</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
4.开机默认启动Apache和Mysql服务</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_695944">
<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>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash functions">sudo</code> <code class="bash plain">chkconfig httpd on</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash functions">sudo</code> <code class="bash plain">chkconfig mysqld 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>
可以用上面两个命令来选择开机启动Apache和Mysql.</p>
<p>
5.测试PHP是否安装成功</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_823885">
<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 functions">sudo</code> <code class="bash plain">nano </code><code class="bash plain">/var/www/html/info</code><code class="bash plain">.php</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
你可以用上面的命令来新建一个info.php文件，nano是简单的文本编辑工具，还有vim。<br>
输入简单的测试PHP命令：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_197987">
<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"><?php</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">phpinfo();</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash plain">?></code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
然后输入Ctrl o进行保存，点击回车确认。再输入Ctrl x进行退出。<br>
然后在浏览器中，输入IP地址加上info.php，就可以看到PHP的信息了！类似下面的图：</p>
<p>

环境配置完毕，先到这里吧，后续文章再介绍如何安装WordPress。</p>
