I hope someone can give me a hand figuring this out. I have been running APC recently on some of my servers that host only one application and it’s been working great. Unfortunately I went to run it tonight on my workhorse web server and as soon as I turned it on I started getting ‘mixing’ from my wordpress blogs. The first blog to get loaded would cache database information and then every blog loaded later would get a database error.
What I want to know is if there is a way to prefix the cache somehow so that I can avoid this problem. I assumed that the cache would respect the differences in absolute pathing between the files and not use the same cached copy on multiple sites… FAIL
Thanks in advance!
Update
As requested here is a copy of the apc.ini file that I use in /etc/php.d/ to override default settings:
/etc/php.d/apc.ini
extension=apc.so
apc.shm_size = 64M
apc.max_file_size = 8M
apc.include_once_override = 1
apc.stat_ctime = 1
As far as i knnow you cannot use global settings to set prefix for different applications. You could change your key names and add prefix to its names. If youre more skilled you could use two different instances of php using fastcgi, depending on what http server youre using. We’re doing something like that using APC and ngix 🙂
