Redis自动安装部署

本文总共分为4个部分：

redis自动安装脚本目录结构说明；

redis自动安装脚本内容；

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自动安装脚本目录结构说明：

# ls 查看当前目录包含以下3个文件

-- install_redis.sh # redis自动安装脚本

-- 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）
