redis自动化安装脚本

    由于开始接触redis的自动化运维，为了方便后续工作的进行，写了一个redis自动化安装脚本，可以实现安装、配置、并可以使用service redis start/stop控制服务的启动和停止，参考博文http://blog.csdn.net/ludonqin/article/details/47211109

此脚本已经在Centos6.3环境下测试无误，脚本内容如下：

#redis自动安装脚本:

#pid文件：/var/redis/run/redis.pid

#配置文件:/etc/redis/redis.conf

#日志文件:/var/redis/log

#数据文件:/var/redis/data

#!/bin/bash

Soft_dir="/home/redis"

Download_URL="http://download.redis.io/redis-stable.tar.gz"

#3.2.9

Redis_Version="stable"

#此函数用于判断是否为root用户

root_or_not(){

if [ `id -u` != 0 ] ; then

    echo -e "\e[1;44m  <====You are not root,Please login in root!====> \e[0m"

    exit 1

fi

}

#此函数用来使用户选择是否安装redis

install_or_not(){

    read -p "Install redis, Input Y/y ; Do not install  redis,Input N/n:" INSTALL_OR_NOT

    case $INSTALL_OR_NOT in

    Y|y)

        install_redis

    ;;

    N|n)

        echo -e "\e[0;44m <====Stop  install  Redis====> \e[0m"

        exit 1

    ;;

    *)

        echo -e "\e[1;44m  Only Input  Y/y or N/n  \e[0m"

        install_or_not

    ;;

    esac

}

#此函数用来检查上一个命令的执行状态结果返回值，若执行未成功，则退出

check_result(){ 

    if [ $1 != 0 ];then

        echo -e "\e[1,44m  <==== Error,Exit install redis ====> \e[0m"

        exit 1

    fi

}

#此函数用于实现redis的安装、配置、启动停止

install_redis(){

[ ! -d ${Soft_dir} ] && mkdir ${Soft_dir}

cd ${Soft_dir}
