These days, there are many web developers working remotely. We can now find a plenty of collaboration tools and file-sharing applications such as Dropbox. However, one of the problems faced when is that web documents that you save will not be accessible through a
localhost address from the browser, as they are outside the Apache Server
To solve this issue, you can change the
DocumentRoot path to point to the Dropbox folder. But even though this can be done easily in MAMP with the GUI, you may need to change the path – back and forth – to access other websites that are saved in the initial path, which is highly inefficient.
An alternative option you can use is by creating a Symbolic Link (Symlink) and Apache Alias. These allow us to keep the original file in the Dropbox while still being able to access it through the
localhost address in the browser – as if the actual folder is in Apache
DocumentRoot. This is what we are going to look at in this post.

Symlink in OS X
In OS X as well as the other UNIX-based OS, like Ubuntu, a Symlink is created through Terminal with the following command.
ln -s path/to/source path/destination/symlink
For instance, you have your website files saved under the “Dropbox/Sites/project” directory. In Terminal type the following command to put a Symlink to that folder.
ln -s Dropbox/Sites/project ~/Sites/project
Certainly, you need to change the destination path. If you are using MAMP you can set the path to
/Library/WebServer/Documents if you are using the built-in Apache from OS X.
One thing that distinguishes Symlink from Shortcut or the Alias Folder is that a Symlink will be treated like the original file. Symlink can be accessed through Terminal and can also be added to any GUI application. In SublimeText, for instance, you can add the Symlink, instead of the original source as a Project. We would not be able for doing so with a Shortcut and an Alias folder.
Symlink in Windows
In Windows, a Symlink is denoted with the
mklink command as follows:
mklink /d "path\destination\symlink" "path\to\source"
Launch Command Prompt, type this command below to create a Symlink in WAMPServer directory that points to the source in Dropbox.
mklink /d "c:\wamp\www\project" "c:\Users\thoriq\project"
Apache Alias in OS X
Aside from creating a Symlink folder, we can also use Apache Alias. Not to be confused with an Alias Folder, Apache Alias is a module in Apache for URL mapping that denotse one particular path with an Alias. That way you can also access folders through the
localhost address – as if it is stored inside the Apache DocumentRoot.
Before we can create one, ensure that the
mod_alias module is loaded. From Terminal, navigate to
/etc/apache2, and open the
httpd.conf file. Remove the hash sign at the beginning of the following line:
LoadModule alias_module libexec/apache2/mod_alias.so
At the same time, add this line at the very bottom of
httpd.conf, as we will create a dedicated folder, named “alias” to save all Apache Aliases, so that the folder as well as the configuration files in it are picked up.
Type the following two lines in Terminal to create the “alias” folder and “app.conf”, where we will write the Alias configuration.
sudo mkdir /etc/apache2/alias sudo touch /etc/apache/alias/app.conf
Type this command below to open the
app.conf in SublimeText.
sudo subl /etc/apache/alias/app.conf
Apache Alias is specified this way:
Alias /alias-name "/source/of/original/folder"
Below is one complete example. You can add these in
app.conf which we have created above.
Alias /app "/Users/thoriq/Dropbox/app" <Directory "/Users/thoriq/Dropbox/app"> Options Indexes FollowSymLinks MultiViews AllowOverride all Order allow,deny Allow from all </Directory>
Save the file and restart Apache. And given the above specification, you should be able to access
localhost/app address through the browser even though the actual folder is in the Dropbox folder.
Apache Alias in Windows
If you are running on Windows and using WmpServer, you can create Apache Alias with ease. First, click WampServer icon in the taskbar and navigate to “Apache/Alias directories/Add an alias” menu.
A new window similar to Windows Command Prompt will pop up. In it, set the name of the alias. If you name the alias as “app”, for instance, it will later be accessible within
localhost/app address in the browser. Press Enter to confirm the alias name.
Then, specify the source of the alias. For instance,
We are done.
In this post, we have shown you how to create Symbolic Link and Apache Alias, which would be useful to access and manage folders outside the Apache
