Good way to bind 2 server folders from a web page 1

[OrganizedChaos]

Hi there, I am trying to make an interface to do some scripting tools I normally run from a bash script and convert them to php pages.

I need to figure out how to run the command from a webpage

mount --bind /olddir /newdir

This allows me to access files in /olddir by going to /newdir (I'm using it to isolate ftp directories)

So, I have figured out how to permanently enter this in the fstab file, but I would also like to put in the above code to make it active before a reboot.

I have tried

exec("mount --bind /olddir /newdir");

along with shell_exec() and system()... I am assuming that this is a permissions thing, but I dont know what I need to do to fix it?

It's probably the user as which you are trying to run the command. A lot of unix-like OSes limit the commands a non-root user can run. Anything run through a web browser is going to run as the user as which the web server runs, and that user is typically non-root for very good reasons.

You might try running the command through sudo.

You might play around with Apache suExec (

http://httpd.apache.org/docs/1.3/suexec.html)

Thanks for pointing me in the right direction...

I ended up using the command

exec("sudo mount --bind /olddir /newdir");

and adding the line

apache          ALL=/bin/mount, NOPASSWD: /bin/mount

to my /etc/sudousers file

This only allows apache to sudo the mount command.
