Redis cache error

[bladex21]

Hello

Rdis is installed on my server and the 4 lines are added

"$config['redis_host'] = '127.0.0.1';
$config['redis_port'] = '6379';
$config['redis_database'] = 0;
$config['redis_password'] = '';"

But still i get these error.

Redis cache error looks like you want to use Redis as a cache engine but script can not connect to it
PHP compiled w\o REDIS library contact admin to fix this issue.
