RamNode CentOS 7.0 Netinstall Guide for RamNode CKVM VPS server

How to install CentOS 7 via Netinstall on Ramnode CKVM VPS

Ramnode offers CentOS 7 netinstall option for their SSD KVM or SSD-Cached KVM VPSes which differs from the full CentOS 7.0 DVD install I outlined previously in that you specify the source repo mirror where you grab the actual files.



I decided to try this on one my of Ramnode 512MB memory based CKVM VPS based in Seattle. I picked a close CentOS 7 mirror for the source repository in Washington http://centos.eecs.wsu.edu/7/os/x86_64/.

Below is a screenshot guide to CentOS 7 netinstall via the Solus VM VNC Console. I did a custom CentOS 7 XFS partition giving swap partition an extra 1GB.

Do you want to run YUM install checks ?  [y/n]

This will increase your upgrade duration time wise.
Check the change log centminmod.com/changelog.html
to see if any Nginx or PHP related new additions
which require checking YUM prequisites are met.
If no new additions made, you can skip the
YUM install check to speed up upgrade time.

PHP Upgrade - Would you like to continue? [y/n] y

Detected PHP 5.5 branch.
You can compile Zend OPcache (Zend Optimizer Plus+) support
as an alternative to using APC Cache or Xcache cache.
But Zend OPcache only provides PHP opcode cache and
DOESN'T do data caching, so if you web apps such as Wordpress,
Drupal or vBulletin require data caching to APC or Xcache,
it won't work with Zend OPcache.

* Installing imagick PHP Extension
*************************************************

Seems some issues with menu option 10 for Memcached reinstall that need to check out too. Okay problem wasn't with menu option 10, but with the way I setup .08 centos 7 beta 01 to map service servicename restart to systemctl restart servicename. It doesn't register with PHP-FPM to reload and make the PHP extensions available.

Issuing proper service php-fpm restart, registers all the PHP extensions properly.

FYI, was just doing some yum updates for a CentOS 7.0 512MB VPS and ran out of memory with 0 swap assigned. So added a 2GB Swap file to the VPS and tried yum updates again and saw swap used was up to 480MB. So it does seem true that for CentOS 7.0 you need a minimum of 1GB of memory to get by given that the yum update easily consumed 512MB + 480MB = 992MB of memory.

So be aware if you want to use CentOS 7.0 either a minimum of 1GB of memory is required or at least 512MB of memory + ample swap disk allocation is required !

these were the YUM updated packages involved.
