Tested on Ubuntu 10.10 64bit server edition but should apply to other versions as well.
sudo apt-get install php5-dev
php5-dev provides the dev library as well as the phpize command which is required for the compiling step
2) Get phpredis source code, should be pretty easy by running
git clone git://github.com/nicolasff/phpredis.git
3) Compile and install
cd phpredis phpize ./configure make sudo -s make install
4) Enable the phpredis extension
sudo -s echo "extension=redis.so">/etc/php5/conf.d/redis.ini exit
5) Write a simple php script to test (running on cli would be fine if php5-cli is installed)
<?php // phpredis_set.php $redis=new Redis() or die("Can'f load redis module."); $redis->connect('127.0.0.1'); $redis->set('set_testkey', 1);
Prior to try phpredis I was using Rediska as the php redis client. I did some pretty quick and dirty benchmarking comparison and phpredis is clearly a winner here, not surprisingly because phpredis is a compiled extension written in C while Rediska is a pure php library.
time for i in `seq 1 1000`; do php phpredis_set.php; done
time for i in `seq 1 1000`; do php rediska_set.php; done
and the source code for rediska_set.php:
<?php require_once 'Rediska/library/Rediska.php'; $rediska=new Rediska(); $rediska->set('set_testkey', 1);
The above tests were conducted on a single-core i3 2.1GHZ Virtualbox guest with 512MB of RAM.
