http://redis.io/clients 

=> 공식 사이트 들어가보면  아래 두가지를 추천하는 듯함

Predis ☺ ★ Repository JoL1hAHN Mature and supported

phpredis ☺ ★ Repository yowgi This is a client written in C as a PHP module.


아무래도 C로 작성된 PHP 모듈이 성능이 더 좋지 않을가?? 라는 생각에 아래 phpredis 하기로함
테스트는 해봐야겠지만.............
그리고 보니까...  https://github.com/nicolasff/phpredis#php-session-handler 도 지원함 좋다!!

설치방법 아래 참조

$ wget https://github.com/nicolasff/phpredis/zipball/master -O phpredis.zip
$ unzip phpredis.zip 
$ ll
drwxr-xr-x  5 root root   4096 Sep  3 04:27 nicolasff-phpredis-4c1f1bc

$ cd nicolasff-phpredis-4c1f1bc/
$ phpize 
Can't find PHP headers in /usr/include/php
The php-devel package is required for use of this command.

$ yum install php-devel #PHP devel 미설치시 설치하기!
$ phpize
Configuring for:
PHP Api Version:         20121113

##### php.conf 디렉토리에 맞게 ini 에 extension 등록하기! 안되면 php.ini등록해도됨
$ echo extension=redis.so > /etc/php.d/redis.ini 


##### 웹서버종류에 따라서 Apache Restart 또는 php-fpm restart
$ /etc/init.d/php-fpm restart

##### 최종확인
$ php -i | grep 'Redis Version'
Redis Version => 2.2.5

<?php phpinfo() ?> 
redis
Redis Support => enabled
Redis Version => 2.2.5
