　　LAMP is short for Linux, Apache, MySQL,PHP.This tutorial shows how you can install an Apache2 webserver on anUbuntu 12.04 LTS server with PHP5 support (mod_php) and MySQL support.
　　I do not issue any guarantee that this will work for you!
　　

1 Preliminary Note
　　In this tutorial I use the hostname server1.example.com with the IP address192.168.0.100. These settings might differ for you, so you have to replace them where appropriate.
　　I'm running all the steps in this tutorial with root privileges, so make sure you're logged in as root:
sudo su
　　

2 Installing MySQL 5
　　First we install MySQL 5 like this:
apt-get install mysql-server mysql-client
　　You will be asked to provide a password for the MySQL root user - this password is valid for the userroot@localhost as well asroot@server1.example.com, so we don't have to specify a MySQL root password
manually later on:
　　New password for the MySQL &quot;root&quot; user:
<-- yourrootsqlpassword

Repeat password for the MySQL &quot;root&quot; user:
<-- yourrootsqlpassword
　　

3 Installing Apache2
　　Apache2 is available as an Ubuntu package, therefore we can install it like this:
apt-get install apache2
　　Now direct your browser to http://192.168.0.100(this is yourself IP), and you should see the Apache2 placeholder page (It works!):


　　Apache's default document root is /var/www on Ubuntu, and the configuration file is/etc/apache2/apache2.conf. Additional configurations are stored in subdirectories of the/etc/apache2
directory such as /etc/apache2/mods-enabled (for Apache modules),/etc/apache2/sites-enabled (for virtual hosts), and/etc/apache2/conf.d.
　　

4 Installing PHP5
　　We can install PHP5 and the Apache PHP5 module as follows:
apt-get install php5 libapache2-mod-php5
　　We must restart Apache afterwards:
/etc/init.d/apache2 restart
　　

5 Testing PHP5 / Getting Details About Your PHP5 Installation
　　The document root of the default web site is /var/www. We will now create a small PHP file (info.php)in that directory and call it in a browser. The file will display lotsof useful details about our
PHP installation, such as the installed PHPversion.
vi /var/www/info.php


<?php
phpinfo();
?>
　　Now we call that file in a browser (e.g. http://192.168.0.100/info.php):


　　As you see, PHP5 is working, and it's working through the
Apache 2.0 Handler, as shown in the Server APIline. If you scroll further down, you will see all modules that arealready enabled in PHP5. MySQL is not listed there which means we don'thave MySQL support in PHP5 yet.
　　

6 Getting MySQL Support In PHP5
　　To get MySQL support in PHP, we can install the php5-mysqlpackage. It's a good idea to install some other PHP5 modules as well asyou might need them for your applications. You can search for availablePHP5 modules like this:
apt-cache search php5
　　Pick the ones you need and install them like this:
apt-get install php5-mysql php5-curl php5-gdphp5-intl php-pear php5-imagick php5-imap php5-mcrypt php5-memcachephp5-ming php5-ps php5-pspell php5-recode php5-snmp php5-sqlitephp5-tidy php5-xmlrpc php5-xsl
　　Now restart Apache2:
/etc/init.d/apache2 restart
　　Now reload http://192.168.0.100/info.phpin your browser and scroll down to the modules section again. Youshould now find lots of new modules there, including the MySQL module:


　　

7 phpMyAdmin
　　phpMyAdmin is a web interface through which you can manage your MySQL databases. It's a good idea to install it:
apt-get install phpmyadmin
　　You will see the following questions:
　　Web server to reconfigure automatically:
<-- apache2

Configure database for phpmyadmin with dbconfig-common?<-- No
　　Afterwards, you can access phpMyAdmin under http://192.168.0.100/phpmyadmin/:

如何安装phpmyadmin-Mysql 数据库管理
　　
使用界面管理器：

系统->系统管理->新立得软件包管理器->搜索 phpmyadmin->右键标记安装。

或直接使用一条命令：sudo apt-get install phpmyadmin 安装开始。
phpmyadmin设置：

在安装过程中会要求选择Web server：apache2或lighttpd，选择apache2，按tab键然后确定。然后会要求输入设置的Mysql数据库密码连接密码 Password of the database’s administrative user。

然后将phpmyadmin与apache2建立连接，以我的为例：www目录在/var/www，phpmyadmin在/usr/share/phpmyadmin目录，所以就用命令：sudo ln -s /usr/share/phpmyadmin /var/www 建立连接。
phpmyadmin测试：在浏览器地址栏中打开http://localhost/phpmyadmin。ok了，没有遇到其他问题。O(∩_∩)O~~
