I am trying to get into PHP app deployment with Capistrano. I have two config files that I need to be "edited" depending on where I deploy it. It's basic stuff like database name and root url (Codeigniter). Can I make Capistrano edit specified automatically? Let's say I want to edit the following in the file /system/config/edit.php:
$test = '';
// edit to
$test = 'Hello World';
Thanks, Max
What I generally do in this kind of situation (even though I don't use Capistrano) is to have several config files commited to source control.
For instance :
config.php
for development machines
config.testing.php
config.staging.php
config.production.php
And when deploying the application to the server, I just have to copy the file corresponding to the current environment to " config.php
" -- as this one is the one that's always used by the application.
It means that I have to do a file copy during the build process, yes, but :
If your configuration files become too complex, and duplicate lots of stuff, you can think about having one "default" config file, that's always included, and sub-config files that only define what depends on the environment.
What that, what I said before still stands : just include the "default" file at the begining of each other.
My Unix is knowledge isn't quite up to scratch so I can't quite get the syntax perfect for what you want. However, Capistrano allows you to directly use the Unix command-line by invoking :run_method within your configs.
The Capistrano code might look something like the following:
run "grep -R --files-with-matches '$test = "";' /system/config/ | xargs perl -pi~ -e 's/\$test = "";/$test = "Hello World";/'"
I would check up on that find and replace function working as expected before implementing it live though.
If you need any more help, I'd recommend checking out the Capistrano Handbook , it should answer most of your questions.
