一步一步教你用PHP+MySql搭建网站 No.0 准备工作

新开一个系列教程吧，这次是讲如何用PHP+MySQL搭建网站。

之前一直有想过搭建自己的个人网站，然后上周通过阿里云申请的域名和空间都通过审核了，于是就开始研究如何用PHP+MYSQL搭建网站，研究了差不多两周，总算搞定了一个小型的blog类的网站。当然，整个过程是通过学习《PHP and MySQL web development》下来的，这篇教程中的例子是在原书中的Chapter 28: Building a Content Manager System章节的基础上，修改完成的。所有的源代码可以在这里找到，本来想买中文版的书来看，但是看评论说翻译的不行，然后就直接看的原版第3版的英文PDF，有想要的同学可以自行google或者给我留言。

我是从0开始学习PHP+MySQL的，基本上网站搭建下来花了不到两周；当然，这里需要你有一定的HTML和SQL的基础，很基本的就行了。PHP其实就是个脚本语言，在原来的HTML中，把需要动态计算的部分用PHP完成，其实最后输出出来的还是HTML的格式。

所以不用觉得很困难，当然我在学习的过程中还是经历的很多痛苦的，因为书本资料比较久远，而且阿里的云主机也不知道怎么连数据库，所以很有必要记录下来。

按照惯例，我们来看下需要完成哪些准备工作吧。

1. 首先你需要有一个自己的域名和主机。

这个我是通过阿里云注册的（www.net.cn）里面有域名申请，我申请了一个.cn的，一年29块钱。域名申请很简单，掏钱就可以了。主要是之后还要申请主机，这样可以把你的域名解析成你的主机ip地址，然后用户访问你的域名以后就能跳转到你的主机上去，找到相应的网页文件了。

整个主机申请的过程可以参照网站上面的介绍，里面有特别详细的过程，包括填写资料，上传省份证、到指定地点拍照、邮寄资料，然后就等待审核吧。我之前的所有步骤，就是拍照、邮寄资料这些的都是两天就搞定了，但是最后资料审核特别慢，基本上两周才审核通过。你也可以申请国外的主机，好像不用审核，但是需要收费。国内阿里会免费提供你一个主机，但是就是需要审核。

这个是我在阿里的主机界面，在下面的新手必读里面，写的比较清楚，按照这个步骤来，你的主机申请是没啥问题的。

2. 数据库操作

这个步骤我研究了好久才弄明白在哪里操作。本来按照上图里面的3步骤来，本地下了个Mysql然后无论如何也连接不到远程去。后来无意间发现可以在网页上管理数据库。

就是上图里面的，在你的主机目录后面，点击“管理”，然后就跳转到这个页面：

然后点击顶端的“数据库信息”

点击右边的“管理”

然后就到了登录界面，登录以后，在命令行页面就可以操作数据库了，建表、插入、删除等等操作，写完了以后 ctrl+enter就执行了

然后就可以执行bookmarks.sql里面的响应的sql语句，建好我们这个程序需要用到的几个表

代码如下：

然后我们需要插入一些测试数据，直接用教材里面的吧：

3. 好像基本也没啥了，然后推荐几个比较好用的HTML编辑器吧。

我用的两个感觉还不错。

首选 Komodo edit，该有的功能都有了，左边可以看到目录，然后语法支持的也比较好，写起代码来很舒服
