Good afternoon. We’re exploring some Google Cloud options for our PBX, which sadly doesn’t offer installation from ISO. So, I’m following the step-by-step for CentOS7 (fantastically written, btw), and came across a snag.

This article walks through how to install the Zend Guard loader (among other things), but at the third step, it fails. I’ve even broken up the command into individual components and it’s the initial component that fails to install:
php-5.3-zend-guard-loader
The failure shows:
====================
yum -y install php-5.3-zend-guard-loader sysadmin fail2ban incron Image
Magick
Loaded plugins: fastestmirror, langpacks
base | 3.6 kB 00:00:00
extras | 3.4 kB 00:00:00
One of the configured repositories failed (Unknown),
and yum doesn’t have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work “fix” this…
…

Cannot find a valid baseurl for repo: schmooze-commercial/7/x86_64
Does anyone have any thoughts as to why this might be failing, and what can be done to correct?
Ah, ok. So I should spin up a build with CentOS 6.7 (DOH!!!) 
Thanks.
If only it were that easy. CentOS6 step-by-step, at the “install FPBX” step (commands below) failed:
cd /usr/src
wget http://mirror.freepbx.org/modules/packages/freepbx/freepbx-13.0-latest.tgz
tar xfz freepbx-13.0-latest.tgz
rm -f freepbx-13.0-latest.tgz
cd freepbx
./start_asterisk start
./install -n
[root@fpbx-template-centos6 freepbx]# ./install -n
PHP Fatal error: Call to undefined function FreePBX\Install\posix_getpwuid() in /usr/src/freepbx/installlib/instal
lcommand.class.php on line 169
Ran through it step-by-step twice to be sure.
Interestingly, the below step in the instructions was the culprit. I ended up having to pull out each item individually and do a “yum install xxxxxx” for each item. There were several items that didn’t say “already installed”, but instead downloaded.
