安装方式是基于brew的，所以先要确保系统已经安装brew
1.安装redis
brew install redis
2.创建链接并添加到开机启动
ln -sfv /usr/local/opt/redis/*.plist ~/Library/LaunchAgents
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.redis.plist
3.启动服务
执行完后服务一般就已经启动
如果自己启动的话执行命令：
redis-server
4.客户链接测试
执行
redis-cli
结果：
MacBook-Pro:Cellar$ redis-cli
127.0.0.1:6379>set aa 'a'
OK
127.0.0.1:6379> get aa
"a"
127.0.0.1:6379> del aa
(integer) 1
OK，安装完毕
python安装redis库
说明：
mac系统默认是自带了python的，但是没安装pip，所以安装一下pip:
sudo easy_install pip
这时会把pip也安装上去了
可以在命令后执行pip看安装成功没

安装redis python库：
sudo pip install redis
测试一下：
MacBook-Pro:~ $ python
Python 2.7.10 (default, Oct 23 2015, 18:05:06)
[GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.59.5)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import redis
>>>
没有报错，redis库安装成功
来段测试代码：
>>> import redis
>>> conn=redis.Redis()
>>> conn.set('a','hello,world')
True
>>> conn.get('a')
'hello,world'
>>>
