php 7 install throws "Cannot load Zend OPcache - it was already loaded" error

Question

I am using salt to provision my servers, and I just tried to upgrade to php 7 and although everything is installing correctly, anytime I run php -v or run any php anything it throw this at the head of any output: Cannot load Zend OPcache - it was already loaded. If I uninstall if I see this, Failed loading /usr/lib64/php/modules/opcache.so: /usr/lib64/php/modules/opcache.so: cannot open shared object file: No such file or directory

Here is the full output from php-v with and with out the php-opcache installed.

I install with this (in the salt state file)

remi-php70-repo:
  pkgrepo.managed:
    - humanname: Remi PHP 7 Repository
    - baseurl: http://rpms.famillecollet.com/enterprise/$releasever/php70/$basearch/
    - gpgcheck: 0
    - require_in:
      - pkg: php-fpm

php-fpm:
  pkg.latest:
    - pkgs:
      - php-fpm

php-opcache:
  pkg.latest:
    - pkgs:
      - php-opcache

And I know it is installing from the 7.0 repo based on a yum install php-opcache and then a php -v

terminal output

I have not be able to find anything related on this at all. Any ideas would be great.

Notes that may be helpful:

1. This is a vagrant server loading CentOS 6.5
2. Provisioning is provided via salt
3. the install is clean when salt runs

Updates

So I have tried with out installing the Zen Opcache thinking it was complied in with php 7, it is not. I am trying to look at what is loading or if there is some issue with the opcache.ini file I provision in. Maybe there is some new settings with the php5 moving to php 7 in that area.

Answer 1

Turns out that I was loading a opcache.ini file which was what php 5 used by default, but in php 7 it was loaded as 10-opcache.ini by default so when my file of opcache.ini was provisioned in it had two .ini files and was trying to load the plugin twice.

I'm not going to delete this question as I believe it is an error that is easy to overlook and may be helpful since you can't really google that error phase and not one place that had anything on it said anything about doubled ini files or declaring the extension twice.
