PHP-OPcache extension

[1991KAHUNA]

I am running Centos 7 and installing moodle 3.1.9. Moodle suggest that I install and PHP-OPcache extension. PHP setting should be changed.

Message: PHP setting should be changed. PHP opcode caching improves performance and lowers memory requirements, OPcache extension is recommended and fully supported.

When i run the recommended update:yum install php-opcache.

These are the results below:

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

I also ran the suggested work arounds above:

[root@localhost ~]# yum install php-opcache --skip-broken

I found a post on Centos forum pertaining to cent 6.5

My yum list \*opcache\* shows that IUS has phpXXu-opcache packages for 56, 70 and 71 but since you're using the distro php 5.4.16 I suspect you want the php-pecl-zendopcache.x86_64 from EPEL.

We don't recommend or support the webtatic repo.
