redis第一步：安装与测试
安装redis，到redis.io下载最新稳定版redis安装文件，这里的安装环境是ubuntu server 11.10 64位。
?
进入解压的目录，执行make PREFIX=/home/software/redis-2.4.6 install
?
安装最后：
?
mkdir -p /home/software/redis-2.4.6/bin
cd src
cp -p redis-server /home/software/redis-2.4.6/bin
cp -p redis-benchmark /home/software/redis-2.4.6/bin
cp -p redis-cli /home/software/redis-2.4.6/bin
cp -p redis-check-dump /home/software/redis-2.4.6/bin
cp -p redis-check-aof /home/software/redis-2.4.6/bin
mkdir -p /home/software/redis-2.4.6/conf
cd ..
cp ?redis.conf /home/software/redis-2.4.6/conf
?
将以上文件复制到redis-2.4.6安装目录下。
?
在安装文件解压目录测试runtest提示没有安装tcl8.5，再安装即可apt-get install tcl8.5，然后执行runtest查看测试即可。
?

?开发测试现阶段不需slave，先忽略。

测试下redis能不能用，到bin目录./redis-server，./redis-cli，运行几个简单的命令测试下能用即表示安装成功。
