Install Apache + PHP on Ubuntu 14.04

1.更新apt-get
sudo apt-get update

2.安裝apache
sudo apt-get install apache2 libapache2-mod-auth-mysql


3.安裝php以及所需extension：
sudo apt-get install php5 php5-mysql php5-mcrypt php5-curl


4.重開apache service
sudo service apache2 restart


其他一些常用設定路徑:
1.Configuration File Path
/etc/php5/apache2/php.ini

2.Loaded Configuration File
/etc/apache2/apache2.conf

3.The default Ubuntu document root
/var/www/html

By default, Ubuntu does not allow access through the web browser to any file apart of those located in/var/www, public_html directories (when enabled) and /usr/share (for web applications). If your site is using a web document root located elsewhere (such as in /srv) you may need to whitelist your document root directory in /etc/apache2/apache2.conf.

The default Ubuntu document root is /var/www/html. You can make your own virtual hosts under /var/www. This is different to previous releases which provides better security out of the box.
