CentOS 7 安装Redis 2.8.7
1、下载软件：
wget wget http://download.redis.io/releases/redis-2.8.7.tar.gz
2、解压软件并编译安装:
tar -zxvf redis-2.8.7.tar.gz
mv redis-2.8.7.tar.gz redis
cd redis
make&&make install
等待编译一端时间即可(如果您的机器上没有c++编译环境，可以通过yum安装 gcc ，命令：yum -y install gcc)
cd src
启动redis-server：./redis-server ../redis.conf
启动会发送警告:
[16403] 12 Dec 21:55:32.830 # WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
安装提示，解决上述问题。默认的情况下，redis监听6379端口。
3、测试使用redis #使用 telnet
[likehua@localhost local]$ telnet localhost 6379 Trying ::1... Connected to localhost. Escape character is '^]'. set likehua likehua +OK get likehua $7 likehua
4、使用redis-benchmark对redis可以进行简单的性能测试。

如果不知道怎么使用redis-benchmark就使用redis-benchmark -help命令，它会告诉你它所有的本领！通过，上面的简单性能测试，你会发现redis简直是性能怪兽！这个数字可是在我的一台普通PC机器上测试的！貌似，比公司的数字大很多，具体原因以后分析。
