安装 Redis：
wget http://download.redis.io/releases/redis-2.8.24.tar.gz
tar xf redis-2.8.24.tar.gz
ln -s redis-2.6.14 redis #建立一个链接
cd redis
make PREFIX=/usr/local/redis install #安装到指定目录中
注意上面的最后一行，我们通过PREFIX指定了安装的目录。如果make失败，一般是你们系统中还未安装gcc,那么可以通过yum安装：
yum -y install gcc*
将redis做成一个服务
cp utils/redis_init_script /etc/rc.d/init.d/redis
vim /etc/rc.d/init.d/redis
在#!/bin/bash 下面加入以下代码：
#chkconfig: 2345 80 90
修改
EXEC=/usr/local/redis/bin/redis-server
CLIEXEC=/usr/local/redis/bin/redis-cli
在start)函数中修改：
$EXEC $CONF
为：
$EXEC $CONF &
保存退出
创建Redis的配置文件目录：
mkdir /etc/redis
find / -name redis.conf
grep "REDISPORT=" /etc/rc.d/init.d/redis
cp /soft/redis-2.8.24/redis.conf /etc/redis/6379.conf
chkconfig --add redis
将Redis的命令所在目录添加到系统参数PATH中
修改profile文件：
vi /etc/profile
在最后加入：
export PATH="$PATH:/usr/local/redis/bin"
启动Redis：
/usr/local/redis/bin/redis-server /etc/redis/6379.conf &
这样就可以直接调用redis-cli的命令了，如下所示：
$ redis-cli
redis 127.0.0.1:6379> auth superman
OK
redis 127.0.0.1:6379> ping
PONG
redis 127.0.0.1:6379>
至此，redis 就成功安装了。
如果在执行redis-cli中报错：
[root@Redis redis]# redis-cli
127.0.0.1:6379> auth superman
(error) ERR Client sent AUTH, but no password is set
原因是redis没有设置验证口令！
解决方法：
设置Redis密码：
vim /etc/redis/redis.conf
# requirepass foobared
修改为：
requirepass auth密码
将redis写成服务脚本
vim /etc/init.d/redis
#!/bin/sh

function stop()

kill -9 $PID

case "$1" in

保存退出：
将redis添加为服务：
chkconfig --add redis
chkconfig redis on
