Exactly yes that is the case!
Hi,
Ok.
And ofering them a zipped file that they can use to overwrite their own
instance is too complicated?
I mean: I run my own webserver, but would NOT be very happy with
applications that update themself without my knowledge.
I would have to thrust you a lot to let such process run behind my back.
But it can be done of course.
I am unaware of any ready-to-go scripts, sorry.
If you write it yourself, the following things should be considered (to name
a few):
- Which user will have the rights to overwrite the existing files?
- Do you want to do it on demand or really automated?
(If really automated you need a cronjob or something like that)
If on demand, the user that runs PHP (often www-data) should be able to:
1) check if you have a new version available.
(This can be done easily by creating a script on your website that returns
the versionnumber of your latest zipped file)
2) download the file
3) unpack it
4) overwrite the current version (You need a path of course to the install)
The problem with the above approach is that php-user (www-data) will
probably own all the files. Maybe you can conjure up a nice group to solve
that problem, or maybe you don't care. But think about it. :-)
One other thing: Do you need database-schema-updates too? In that case your
script that updates must also have a connection at hand, a connection with
enough rights to change the current databasesheme.
Sounds like a big job if you do it right. :-)
I hope my rabbling helps to get you going. Just my 2 cents.
Good luck.
