Redis的安装配置

step 1：

先从redis的官方网站上下载最新的稳定版本。

目前最新的版本是redis-2.8.7.tar.gz

step 2：

tar -xvf redis-2.8.7.tar.gz解压缩，进入到src目录

然后用make编译一下，编译完成之后，会有提示

[root@wangpeng ~/alston/redis/redis-2.8.7/src]$:make

Hint: To run 'make test' is a good idea ;)

好，那我们来make test一下，竟然会报错。

[root@wangpeng ~/alston/redis/redis-2.8.7/src]$:make test
You need tcl 8.5 or newer in order to run the Redis test
make: *** [test] Error 1

看来redis是以来于tcl的，所以我们需要再去下载一个tcl8.5的包。

[root@wangpeng ~/alston/redis/redis-2.8.7/src]$:yum install tcl

安装完之后，我们再来make test一下就没有问题了。

然后我们启动./redis-server

[root@wangpeng ~/alston/redis/redis-2.8.7/src]$:./redis-server

这样我们的redis就安装好了。
