wget
http://download.redis.io/redis-stable.tar.gztar xvzf redis-stable.tar.gz
cd redis-stable
make
sudo make install (如果是root用户可以不用sudo)
安装完毕后，拷贝下配置文件redis.conf，这里是为了更方便的使用
sudo mkdir /etc/redis/
sudo cp redis.conf /etc/redis/
这时启动下redis看看，启动方法：
redis-server /etc/redis/redis.conf
启动后的界面效果：

如果想要后台运行，可以执行redis-server /etc/redis/redis.conf & ，或者修改配置文件/etc/redis/redis.conf中的daemonize设置为yes即可。
设置为daemonize后，启动redis-server，并使用redis-cli对redis-server进行连接
redis-cli
连接成功后：
geeknimo@bogon:~/Documents/phpredis$ redis-cli

这就表明redis服务启动成功了，至于优化嘛，后面的文章再说
接下来我们去配置php-redis
首先要安装git,php5,apache2,php5-dev
sudo apt-get install php5 php5-dev apache2
安装需要点时间
在php-redis源代码目录下，执行
git clone https://github.com/nicolasff/phpredis.git
phpize
./configure
make && sudo make install
提示信息：
Installing shared extensions: /usr/lib/php5/20121212+lfs/
共享库在上面提示的路径下
配置php-redis
在/var/www/html下创建index.php，里面写上如下内容：
<?php
phpinfo();
?>
并在/etc/php5/mods-available下建立一个redis.ini，内容如下：
extension=redis.so
并在/etc/php5/apache2/conf.d和/etc/php5/cli/conf.d下建立一个与redis.ini的软链接，其中cli这个部分很关键，否则php -m无法得到redis的任何模块信息，即无法成功加载使用phpredis
ln -s /etc/php5/mods-available/redis.ini /etc/php5/cli/conf.d/10-redis.ini
ln -s /etc/php5/mods-available/redis.ini /etc/php5/apache2/conf.d/10-redis.ini
重启apache2服务
sudo service apache2 restart
这里打开ubuntu对应的ip/index.php就可以看到php-redis的配置
Additional .ini files parsed/etc/php5/apache2/conf.d/05-opcache.ini, /etc/php5/apache2/conf.d/10-pdo.ini, /etc/php5/apache2/conf.d/10-redis.ini, /etc/php5/apache2/conf.d/20-json.ini, /etc/php5/apache2/conf.d/20-readline.ini
redis
Redis Supportenabled
Redis Version2.2.5
session
Session Supportenabled
Registered save handlersfiles user redis
Registered serializer handlersphp_serialize php php_binary wddx
有了这些信息后开始进行测试代码
建立testredis.php，内容如下：
<?php
$redis = new Redis();
$redis->connect(’127.0.0.1′,6379);
var_dump($redis->info());
?>
这时执行php testredis.php
可以在终端看到对应的内容
也可以在web端看到相应的内容了。
这样就算基本上搭建好了php-redis。
