Web-Interface to trigger shell-scripts

[beejayf]

Hey y'all!

I am currently looking for a way to start a number of shell-scripts on my raspberry pi from my smartphone. I guess one way to do this would be to host a website on my pi that contains maybe eight tiles that trigger e.g. shell-scripts when touched.

Does anybody know if there es a package that does that - or what I would need to do to implement such a functionality?

Thanks in advance!

hi!
to host a web site you will need a HTTP Daemon

its is then posible launch scripts/processes in a number of different ways
imo Common_Gateway_Interface is the easy way to do this

how you set this up depends on which httpd you use !

i think the most simple bare minimum to get a result is busybox httpd

that link: http://wiki.openwrt.org/doc/howto/http.httpd
has some examples showing busybox + cgi and shell scripts

Thanks!! That sounds quite right!

I installed apache2 (for the sake of being at least a Little familiar with it) and tried some cgi (bash)-scripts.

Simple things work - but if I try to run something that requires some more privileges (like interacting with the hardware) this part of the script will not be executed. I understand that this is due to the security layers built around cgi. Now I am not sure how to get past these restrictions without compromising security.

Any ideas?

Well, you'll either need to investigate how to use group permissions and group membership to work out how to selectively allow the cgi-user to run certain tasks; or maybe you could look at WebIOPi? https://code.google.com/p/webiopi/
(although that's using Python, rather than Bash scripts)

Thanks! I got it to work with specific sudo rights for the script

I wanted to do the same and I have documented the process of getting it working.
