centos下redis安装

下载，解压和安装：
$ wget http://download.redis.io/releases/redis-2.8.19.tar.gz
$ tar xzf redis-2.8.19.tar.gz
$ cd redis-2.8.19
$ make
编译后的可执行文件在src目录中，可以使用下面的命令运行Redis:
$ src/redis-server
你可以使用内置的客户端连接Redis:
$ src/redis-cli
redis> set foo bar
OK
redis> get foo
"bar"

[root@localhost server]# ls

[root@localhost server]# cd phpredis/
[root@localhost phpredis]# ls

然后在php.ini里添加extension=redis.so 

<?php
    $redis = new Redis();
    $redis->connect(‘127.0.0.1‘,6379);
    $redis->set(‘helloredis‘,‘i am ok‘);
    echo $redis->get(‘helloredis‘);
?>
