阿里云服务器安装配置redis的方法并且加入到开机启动(推荐)

 去http://redis.io/download下载redis用FTP工具传到服务器或者按照redis官网写的步骤进行操作
   wget http://download.redis.io/releases/redis-2.8.18.tar.gz//下载
   tar xzf redis-2.8.18.tar.gz//解压
   cd redis-2.8.18
   make//编译

cp redis.conf /etc/redis.conf#复制一份redis配置文件到etc目录下
   打开redis配置文件vi /etc/redis.conf
   修改
   daemonize yes#是否作为守护进程运行
   dir /var/lib/redis/  缓存存放位置
   useradd redis  #增加redis用户
   mkdir -p /var/lib/redis#创建db文件夹
   chown redis.redis /var/lib/redis #db文件放在这里
