【redis运维】redis自己主动安装脚本（仅仅安装redis）
Redis自己主动安装部署
本文总共分为4个部分：
redis自己主动安装脚本文件夹结构说明；
redis自己主动安装脚本内容；
redis的操作系统服务脚本说明；
本文引用的资料链接地址。
说明：本文未涉及redis内存分配器部分的内容。
第一部分
Redis自己主动安装脚本文件夹结构说明：
# ls 查看当前文件夹包括下面3个文件
-- install_redis.sh # redis自己主动安装脚本
-- redis-2.8.9.tar.gz # redis安装包（需make,make test,make install）
-- redis_service_script # redis 操作系统服务脚本（用于配置redis服务开机自启动，以及redis服务管理命令）
