I have Wordpress installation running on two web servers powered by Nginx. I configured Memcached on both servers and I'm using W3 total cache plugin for Memcached:
What's the recommended solution for multiply Memcached servers. I've configured both in W3 plugin (192.168.1.1;11211, 192.168.1.2:11211) but I'm not sure if this a good solution in terms of performance as the cache will be stored on both servers simultaneously? Shall I configure only loopack address on each web server? How this actually works - cache is replicated on both servers in this case?
Could you please provide some good articles/guide how to implement chrooted environment for PHP-FPM?
Which PHP extension is recommended: php-pecl-memcached or php-pecl-memcache. The W3 plugin is not actually recognize php-pecl-memcached.
