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
