Install apache on ubuntu

its very straight forward

open console and write :

sudo apt-get install apache2

ubuntu will ask the password and take care of it.once it done open any browser and write http://localhost

you should get "It Works!!" message. otherwise post the issue here. we will help you.


start / stop / restart the server

sudo /etc/init.d/apache2 start
sudo /etc/init.d/apache2 stop
suco /etc/init.d/apache2 restart

apache2 is autostart with system starts. to avoid that please run this command on terminal.

sudo update-rc.d -f apache2 remove

to restore the settings

sudo update-rc.d apache2 defaults


Changing the default localhost folder
By default, apache will operate on the “/var/www” folder. This means that whatever files you place in this /var/www folder will be visible from the URL http://localhost. In some instances, you may want the “localhost” to point to another folder instead, say /home/user/public_html. Here is how you do it:
First, make sure the /home/damien/public_html folder exists. Create a simple html file, name it index.html and place it in the public_html folder.
Open a terminal and type:
gksu gedit /etc/apache2/sites-enabled/000-default
Change DocumentRoot /var/www to DocumentRoot /home/user/public_html.
Change to .

Save and exit the file.
Restart the apache
sudo /etc/init.d/apache2 restart
Now, in your browser, reload the URL http://localhost. You should see the html file that you have placed in the public_html folder.

Configuring different sites
The above trick allows you to change the default operating folder of apache, however, some of you might not want to override the default settings. An alternative is to create multiple sites and point apache to the active site.
Create a new settings file for your new site.
sudo cp /etc/apache2/sites-available/default /etc/apache2/sites-available/site1
Next, edit this settings file.
gksu gedit /etc/apache2/sites-available/site1
Change DocumentRoot /var/www to DocumentRoot /home/user/public_html.
Change to .
Save and exit the file.
Disable the default setting and make active the site1 settings
sudo a2dissite default && sudo a2ensite site1
Lastly, restart the apache.
sudo /etc/init.d/apache2 restart
With this trick, you can create multiple site configuration file, each pointing to a different folder. You can then easily switch between the sites with the a2dissite and a2ensite command
Enabling .htaccess file
.htaccess file is a powerful file that can be used to control and customize a site server behavior without editing the core Apache module. By default, the .htaccess functionality is turned off and all instances of .htaccess files are completely ignored. The server will not even attempt to read .htaccess files in the filesystem.
To enable .htaccess file, open up the settings file that you have created earlier:
gksu gedit /etc/apache2/sites-available/site1
Scroll down the file until you see the part ““. Underneath that line of code, change AllowOverride None to AllowOverride All.
