Shell之一键自动部署Redis任意版本

脚本用法：`chmod 755 redis-install.sh && sh redis-install.sh {version}` （后面 \{version\}的是你需要的版本号，需要什么版本就写什么版本），我这里安装的4.0.10

脚本内容如下展示：

#! /usr/bin/bash
    ##redis任何版本全程自动化源码编译安装
    ##用法：sh redis-install.sh 4.0.10 （后面跟的是你需要的版本号，需要什么版本就写什么版本），我这里安装的4.0.10
    version=$1
    usage(){

    if [ $# -ne 1 ]
    then
    usage
    exit -1

到这里整改自动安装脚本已成功执行完毕，我们可以收到通过`ps –ef|grep redis`来查看服务状态以及监听端口。
