Install Apache 2 WebServer
Code:
sudo apt-get install apache2

Install PHP5
Code:
sudo apt-get install php5

Install Mysql Server
Code:
sudo apt-get install mysql-server

Apart from default installation of LAMP we need to install php5-curl,from terminal issue the command
Code:
sudo apt-get install php5-curl

After this you need to enable mod_rewrite by issuing this command in the terminal(This is for Clean SEO URLS,you can skip this if you do not want)
Code:
sudo a2enmod rewrite

Install Phpmyadmin
code:
sudo apt-get install libapache2-mod-auth-mysql php5-mysql phpmyadmin

Finally restart the apache
Code:
/etc/init.d/apache2 restart

导入 magento-sample-data:

mysql -u root -p
mysql>create database magento;
mysql>use magento
mysql>source path/data_file.sql

解压 magento 到 /var/www/ 中，或用命令复制：

sudo cp -ri /downloads/magento /var/www/

启动 apache,打开浏览器访问 http://127.0.0.1/magento 进入安装界面，若不改动设置，直接下一步……
若遇到错误提示：

Path “/var/www/magento/app/etc” must be writable.
Path “/var/www/magento/var” must be writable.
Path “/var/www/magento/media” must be writable.

设置对应的文件权限：

sudo chmod -R a+w /var/www/magento/app/etc
sudo chmod -R a+w /var/www/magento/media
sudo chmod -R a+w /var/www/magento/var

相关设置完成后，选择进入 网站前台 或是 管理后台。

linux 小常识 — 设置 Ubuntu Root 用户：

1. 打开终端，输入：sudo passwd root 然后按回车
2. 此时会提示你输入密码，在password:后输入你现在登录的用户的密码
3. 然后系统提示你输入新的UNIX密码
   Enter new UNIX password:这里输入你想为root设置的密码，要输入两次
4. 此时系统会出现密码设置成功的提示，于是就可以用 su rooot 或者 sudo -s -H 切换到root权限
