前提：环境材料准备
- CentOS Linux release 7.2.1511 (Core)
- redis-3.2.8.tar.gz
1.下载（Download）、解压（extract）、完整性检查（How to verify files for integrity）
Redis uses a standard practice for its versioning: major.minor.patchlevel. Redis使用标准做法进行版本控制：
主版本号.次版本号.修订版本号An even minor marks a stable release, like 1.2, 2.0, 2.2, 2.4, 2.6, 2.8. 偶数次版本号表示一个稳定的发行版，如1.2,2.0,2.2,2.4,2.6,2.8。 Odd minors are used for unstable releases, for example 2.9.x releases are the unstable versions of what will be Redis 3.0 once stable.奇数次版本号被用于表示不稳定版本，例如2.9.x版本是不稳定版本，一旦稳定就是3.0
完整性：与 redis-hashes 对照

2. 编译（compile）、安装 （Installing）
In order to install Redis binaries into /usr/local/bin just use:
% make install
You can use make PREFIX=/some/other/directory install if you wish to use a different destination. 如果你想安装二进制命令到不同的目录
Make install will just install binaries in your system, but will not configure init scripts and configuration files in the appropriate place. This is not needed if you want just to play a bit with Redis, but if you are installing it the proper way for a production system, we have a script doing this for Ubuntu and Debian systems:
Make install在系统中只会安装二进制文件，但不会在适当的位置配置init脚本和配置文件。 如果你只想玩一点Redis，这不是必需的。但如果你正在为生产系统安装它找一个更合适的方式， 针对Ubuntu和Debian系统，我们有一个脚本做这些：
% cd utils% ./install_server.sh
The script will ask you a few questions and will setup everything you need to run Redis properly as a background daemon that will start again on system reboots.
You‘ll be able to stop and start Redis using the script named /etc/init.d/redis_<portnumber>, for instance /etc/init.d/redis_6379.
# cd redis-3.2.8
# make PREFIX=/usr/local/redis install
Hint: It‘s a good idea to run ‘make test‘ ;)
# make test...
...
\o/ All tests passed without errors!
Cleanup: may take some time... OK
# mkdir -pv /usr/local/redis/{etc,log,lib}mkdir: created directory ‘/usr/local/redis/etc’mkdir: created directory ‘/usr/local/redis/log’
# cd utils
# ./install_server.shWelcome to the redis service installer
This script will help you easily set up a running redis server
Please select the redis port for this instance: [6379]
Selecting default: 6379
Please select the redis config file name [/etc/redis/6379.conf] /usr/local/redis/etc/6379.confPlease select the redis log file name [/var/log/redis_6379.log] /usr/local/redis/log/redis_6379.logPlease select the data directory for this instance [/var/lib/redis/6379] /usr/local/redis/lib/6379
Please select the redis executable path [] /usr/local/redis/bin/redis-server
Selected config:
Port : 6379
