Advanced Optimization of Rackspace Cloud Server for WordPress

Advanced Optimization of Rackspace Cloud Server for WordPress includes installation of Memcached, PEC, APC, XCache, eAccelerator and installation of New Relic. You must be already running a Server instance with rpm based REHL (Red Hat/CentOS, commands might differ for others) distro variants with already installed and up WordPress from our older video guides (please search in this website, if needed) or installed properly yourself. We prefer Red Hat Enterprise Linux over CentOS for production site, however there is no difference in commands between Red Hat Enterprise and CentOS and using CentOS is encouraged for cost saving. Red Hat Enterprise is taken as the standard, there are a few differences in between, as the two distributions sometimes apply different minor patches. In other words, at the level of most need, you can treat CentOS and RHEL as interchangeable. As basically we have Enterprise grade readers, we just mentioned the point. CentOS is derived entirely from the Red Hat Enterprise Linux (RHEL) distribution with just few mods. This server node is running REHL for the need of paid support, nothing else.
