apache2 php 安装

在ubuntu上安装apache2 和PHP5

如果是ubuntu 11.04 先装一下taskel

sudo apt-get install tasksel

sudo tasksel install lamp-server

然后

sudo apt-get install apache2

sudo /etc/init.d/apache2 restart

如果出现了Could not determine the server's fully qualified domain name, using 127.0.0.1 for ServerName 这种状况 那么

echo "ServerName localhost" | sudo tee /etc/apache2/conf.d/fqdn

建立一个新的site：

Apache2 has the concept of sites, which are separate configuration files that Apache2 will read. These are available in/etc/apache2/sites-available. By default, there is one site available called default this is what you will see when you browse to http://localhost or http://127.0.0.1. You can have many different site configurations available, and activate only those that you need.

As an example, we want the default site to be /home/user/public_html/. To do this, we must create a new site and then enable it in Apache2.

To create a new site:

• Copy the default website as a starting point. sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/mysite 
• Edit the new configuration file in a text editor "sudo nano" on the command line or "gksudo gedit", for example: gksudo gedit /etc/apache2/sites-available/mysite
• Change the DocumentRoot to point to the new location. For example, /home/user/public_html/
• Change the Directory directive, replace <Directory /var/www/> to <Directory /home/user/public_html/>
• You can also set separate logs for each site. To do this, change the ErrorLog and CustomLog directives. This is optional, but handy if you have many sites
• Save the file

Now, we must deactivate the old site, and activate our new one. Ubuntu provides two small utilities that take care of this: a2ensite (apache2enable site) and a2dissite (apache2disable site).

sudo a2dissite default && sudo a2ensite mysite

Finally, we restart Apache2:

sudo /etc/init.d/apache2 restart

If you have not created /home/user/public_html/, you will receive an warning message

To test the new site, create a file in /home/user/public_html/:

echo '<b>Hello! It is working!</b>' > /home/user/public_html/index.html

Finally, browse to http://localhost/

安装PHP5

sudo apt-get install libapache2-mod-php5

sudo a2enmod php5

sudo service apache2 restart
