I've shown previously how to install a LAMP server in Ubuntu. If the purpose of your LAMP installation was to set up your own web development environment, then you may want to do some further configuration to your system. This Apache howto is not intended to cover Apache configuration in depth. This is just some basic configuration to help you set up a web development environment in Linux. For more information, see the official Apache documentation.
Why Change the Apache Configuration?
By default, Apache is set up for your web site's files to be in the /var/www directory. This is fine if you only want to work on one website and access it through http://localhost/. But what if you want to work on several websites at the same time? Well, one solution is to create different directories under /var/www like /var/www/site1 and then access it through http://localhost/site1/. I prefer a more elegant solution.
I prefer to build websites in a directory under my own ID. I can then configure the Apache http server to point to the site directories with URLs like http://site1/, http://site2/, etc.
Creating a Web Development Directory
Lets start off by creating a folder structure for the development environment. You can do this from your file manager. I prefer the terminal.
mkdir site1 site2
We now have a directory called webdev under our home directory. Within the webdev directory are two directories called site1 and site2.
Create Some Test Files
Now we're going to create some basic test files so that we know our Apache configuration worked. Again, I'm going to use the terminal to create these files, but feel free to use your favorite text editor.
echo 'Site1 works!' > index.html
echo 'Site2 works!' > index.html
Enable the Sites in Apache
OK, we're now ready to do the actual Apache configuration. Go to /etc/apache2/sites-available.
As root, copy the default file as site1.
Repeat the process to create a site2 file.
As root, edit the site1 configuration file.
Edit the file to look like this (the changes are in bold).
<VirtualHost *:80> ServerAdmin [email protected] ServerName site1 DocumentRoot /home/yourID/webdev/site1/ <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /home/yourID/webdev/site1/> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn CustomLog /var/log/apache2/access.log combined Alias /doc/ "/usr/share/doc/" <Directory "/usr/share/doc/"> Options Indexes MultiViews FollowSymLinks AllowOverride None Order deny,allow Deny from all Allow from 127.0.0.0/255.0.0.0 ::1/128 </Directory> </VirtualHost>
Note: The line that changes AllowOverride None to AllowOverride All is required if you want to enable URL re-writes through a .htaccess file. You need this if you want to utilize pretty permalinks in WordPress.
You now need to enable your new site.
You should get a message telling you that you need to reload Apache to activate the new configuration. But first you need to edit your /etc/hosts file.
Edit the first line adding site1 to the end of the line so it looks something like this and save the file.
127.0.0.1 localhost site1
You can now reload Apache.
Site1 is now enabled. Check it by browsing to http://site1/. If everything worked right, you should see a web page that says "Site1 works!"
Repeat the procedure to enable site2, etc.
If you get an error like “apache2: Could not determine the server’s fully qualified domain name, using 127.0.0.1 for localhost,” you can fix it with this command.
echo "ServerName localhost" | sudo tee /etc/apache2/conf.d/fqdn
Then, reload Apache to eliminate the error.
sudo /etc/init.d/apache2 reload
