linux - Symbolic Link & LAMPP htdocs



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!



httpd conf (only the parts involving SymLinks)

# The Options directive is both complicated and important. Please see

Answer



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





Options Indexes FollowSymLinks



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.
