UBUNTU SERVER 12.04搭建PHP环境

Ubuntu的Server和Desktop上都配过php的LAMP环境，步骤没什么区别，相关的教程网上也很多，这里把自己的配置过程记录下来，省得每次都google…供参考

整个环境用到Apache2、MySQL、php5和phpMyAdmin

1、安装Apache2

$ sudo apt-get install apache2

装完后在浏览器中访问 http://[server-ip-address] 如看到类似下图的页面，则apache2安装成功

Ubuntu下，apache的配置信息在/etc/apache2目录，默认根目录在/var/www

2、安装MySQL，修改默认字符集

$ sudo apt-get install mysql-server mysql-client

安装过程需要设置root的密码。Ubuntu下，MySQL的配置信息在/etc/mysql目录

MySQL默认的字符集是latin1

为了避免中文可能带来的乱码问题，将默认字符集改成utf-8，具体可以参考这篇文章，修改 /etc/mysql/my.cnf 文件，在相应位置添加

[client]
default-character-set=utf8

[mysql]
default-character-set=utf8

[mysqld]
collation-server = utf8_unicode_ci
init-connect='SET NAMES utf8'
character-set-server = utf8

修改后是这样的

3、安装php5及Apache的php5模块

$ apt-get install php5 libapache2-mod-php5

装完之后重启apache

$ sudo service apache2 restart
* Restarting web server apache2
... waiting                         [ OK ]
$

在 /var/www 目录下新建 info.php 文件，内容如下

<?php phpinfo() ?>

在浏览器中访问 http://[server-ip-address]/info.php 如看到类似下图的页面，则php5安装成功

在 /var/www 目录下新建 testmysql.php 文件，测试php连接MySQL，文件内容如下

<?php
    $link = mysql_connect("localhost", "[用户名]", "[密码]");
    if (!$link)
    {
            die('Could not connect: '.mysql_error());
    }
    else echo "MySQL连接成功";
    mysql_close($link);
?>

在浏览器中访问 http://[server-ip-address]/testmysql.php，HTTP错误500…

4、安装php5的MySQL模块，安装php需要的其它模块

默认安装完的php5是不能与MySQL交互的。通过命令
