Here’s what I eventually figured out about Apache and PHP:<\/p>\n These sites were helpful for the initial set up of PHP as CGI with mod_fcgi and Apache in chroot (mod_fcgi sends one request to each PHP process regardless if PHP children are available to handle more, and no sharing of APC opcode cache across PHP processes):<\/p>\n This site was helpful for setting up PHP as CGI with mod_fastcgi and Apache in chroot (mod_fastcgi sends multiple requests to a PHP process, so the process can send them to children processes, and having one PHP process for each site allows for APC opcode cache to be usable.)<\/p>\n These sites helped me learn about php-fpm and how it is not quite ready for what I have in mind:<\/p>\n I ended up going with Apache’s mod_fastcgi for using PHP as a CGI, and NOT using PHP-FPM, while running Apache in threaded mode with apache.worker enabled.<\/p>\n To get this set up is pretty easy. I already had Apache and PHP installed and running (with PHP as CGI using mod_fcgi), so here are the steps I used to convert it to run mod_fastcgi and apache.worker. I’m running CentOS 6.3.<\/p>\n <\/p>\n Each virtual host needs to have an entry similar to this in the httpd.conf file, or I like to create a separate virtual_host.conf and include that in the main httpd.conf.<\/p>\n Things to note:<\/p>\n Add a Things to note:<\/p>\n Comment out everything in the Edit the Check the Apache configuration files to see if there are any errors.<\/p>\n If all good, restart Apache<\/p>\n Set up log rotation for Apache<\/p>\n Figuring out the possibilities for Apache and PHP reminds me of a Dr. Seuss book, “Fox in Sox”. It’s a favorite of mine. I love reading it to the kids. In it, Mr. Fox tries to get Mr. Knox to say all kinds of ridiculous (in meaning and hard to say) tongue twisters.
