I've glad that I'm able to report some progress :-)
Following your earlier instructions entered this:
phpize && ./configure --enable-apc --enable-apc-mmap --with-apxs=/usr/local/apache/bin/apxs --with-php-config=/usr/local/bin/php-config && make && make install
Here's the last couple of lines of output:
Libraries have been installed in:
Don't forget to run 'make test'.
Following on with your instructions you said:
This will configure APC and install it in your extension directory.
You should see a file named apc.so in that directory
apc.so is not in this directory, but can confirm that it's in /usr/local/src/APC-3.0.19/modules as per the last couple of lines of output I detailed above.
I'm not sure if this creates a problem for me or not. tT this point I've looked through the rest of your earlier instructions...
you should see extension=apc.so somewhere. If not add it then copy the settings from wp-content/plugins/w3-total-cache/ini/apc.ini and add them below extension=apc.so
There's absolutley no mention of 'apc' anywhere in php.ini
so I've added 'extension = apc.so' and the contents of the the apc.ini file you mentiond. I then restarted the httpd service.
Going to the W3 Total Cache plugin admin... APC appears in the dropdown list. I can't believe it!! :-)
Given the different directory name (as I mentioned above) I'm hoping that everything is working as it should be - my website is serving pages so on the surface all appears to be OK. I hope the same goes for 'under the hood'.
You've been a massive help, I really do appreciate it!! Thanks for sticking by and offering me support and step by step instructions right to the end. It's been a massive help and I've learnt quite a bit. Thank you. A very big thank you! :-)
Is there any kind of Dummies Guide to tweaking the APC settings in php.ini to get W3 Total Cache running at it's best?
