Your phpRedis installation doesn't work with php 5.6

This work.
Install Redis 2.2.8 for PHP 5.6

Using Centos 7.0 and EasyApache 4, you can’t install Redis 2.2.8 for PHP 5.6
Easiest workaround is to use shell and following command:
pecl install channel://pecl.php.net/redis-2.2.8

Once it finishes installation, you should see the following lines:
Build process completed successfully
Installing '/opt/cpanel/ea-php56/root/usr/lib64/php/modules/redis.so'
install ok: channel://pecl.php.net/redis-2.2.8
configuration option "php_ini" is not set to php.ini location
You should add "extension=redis.so" to php.ini

Command for test phpredis is work

php -r "if (new Redis() == true){ echo \"OK \r\n\"; }"

Oh man. 46 forks. Which one to choose? Of the forks. 15 modified. 1 with 9 stars and 19 updates, with a tutorial for CentOS 7 linked by a user who was active on GitHub in the last day. Followed those instructions, which had a number of manual steps automated with comment from @vortexau on using the install utility script shipped with the release I built (redis-3.0.4).
