<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">前几篇<span style="color: black;">文案</span>中讲解了<span style="color: black;">怎样</span>搭建docker和Java Web环境的<span style="color: black;">办法</span>，本篇<span style="color: black;">文案</span>来教<span style="color: black;">大众</span>搭建一个好的PHP和Python环境，<span style="color: black;">能够</span><span style="color: black;">帮忙</span><span style="color: black;">研发</span>和运行PHP和Python应用程序，使其更加<span style="color: black;">有效</span>和稳定。</p>
<h1 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">1、</span> PHP环境介绍</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">好的<span style="color: black;">研发</span>环境无疑会大大<span style="color: black;">提高</span>编码效率，<span style="color: black;">近期</span>钻研了一下Python环境安装的问题，稍加总结分享一下。本文以轻量云主机（CenTOS 7.6系统）为例，介绍<span style="color: black;">怎样</span>搭建PHP环境。</p>
<h1 style="color: black; text-align: left; margin-bottom: 10px;">1.1、前置准备</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">正式<span style="color: black;">起始</span><span style="color: black;">安排</span>前，您需完成如下的准备工作：</p>开通京东云账户，若您还未注册京东云账号，可在京东云官网进行注册；账户开通后，需要进行实名认证；购买一台或多台云主机<span style="color: black;">或</span>轻量云主机<span style="color: black;">制品</span>；登录轻量云主机，复制下面<span style="color: black;">过程</span>中的命令进行执行操作；<h1 style="color: black; text-align: left; margin-bottom: 10px;">1.2、搭建PHP环境</h1>
