Linux – Symbolic Link & LAMPP htdocs

documentrootlinuxsymbolic-linkxampp

I went through these steps in order to make a symlink directory to use outside of lampp htdocs.

$ mkdir test
$ chmod 777 test
//test is now in /home/Dropbox/test/
//I put an index.html with 777 perms in it.
$ cd /opt/lampp/htdocs/
$ sudo ln -s /home/Dropbox/test/ /opt/lampp/htdocs/$USER
//my user appears as symlink directory in htdocs.
$ /opt/lampp/lampp stop
$ /opt/lampp/lampp start
//lampp is now restarted

I type in localhost/myusername and get a 404 error… object not found.

Note that I can create regular directories and .html/.php files in the htdocs directory, but I cannot do any symlink directories or .html/.php files, they will not load.

Thank you for input!

Best Answer

This would suggest that the FollowSymLinks is is not present within stanza. Here is an example, taken from here:

<Directory /usr/local/httpd/htdocs>
Options Indexes FollowSymLinks
</Directory>

Pending verification of apache configuration, (which I think you should paste in), this is the most likely answer.

EDIT: After reading your response to embobo, I went and replicated the problem with my server:

[Fri Dec 23 23:03:58 2011] [error] [client 192.168.15.20] Symbolic link not allowed or link target not accessible: /var/www/html/testsym

I suggest the following settings on test's parent

chmod go+x /home/Dropbox

So that the Dropbox directory can have execute permissions for group and other.
