Hello All,
What is the best method to build and deploy php scripts along the different
environments? You can talk about rpm's and stuff
My specific scenario is
Step1:
Developer checks code in to perforce (repo)
Step 2:
Then I need to upgrade my integration instance.
Step 3:
Upgrade QA instance
Step 4:
Upgrade staging Server
Step 5:
Upgrade production machines
What would be the specific build mechanism that I can use for such kind of
environments? I also have db scripts that might alter schema.
Please provide me samples of any scripts that you might have written to
achieve this kid of structure. Any suggestions or scripts will be highly
appreciated.
Personally, I use various branches in our repo to do this kind of roll
out. I have various (simple) scripts that do all the updating on the
various environments and it's usually just a matter of switching to a
different branch.
It kind of depends whether all of your productions environments are
under your control or not. If they are then you can do a kind of direct
access to your repo on them (security considerations aside).
On production, I personally do a pull from the repop to an offline area
on a "master" production server, do rsync dry-runs to online areas (to
get the disc cache all warmed up) to each production server (there can
be more than one!) and then do a quick: disable, rysnc, update, enable
run to do the final deployment.
If we know there are no race type issues in our deployment we can opt to
avoid the disable/enable bit of it and just deploy it live.
Not much in the way of attached scripts but that how I do it and it
works pretty well :)
As a side note, if you have larger load sites, you'll probably be doing
some caching cleverness with APC (or similar), in which case you'll
probably want to invalidate some caches before update. In order to
prevent spike loading upon enabling again, you may also want to do some
kind of "priming" of the caches before opening it all to the public.
