1，首先下载安装
wget http://redis.googlecode.com/files/redis-2.2.13.tar.gz
tar -zxf redis-2.2.13.tar.gz
cd redis-2.2.13
make
sudo make install
cp redis.conf /etc
install的时候，redis的命令会被拷贝到/usr/local/bin下面
2，建立用户与日志目录
第一次启动Redis前，建议为Redis单独建立一个用户，并新建data和日志文件夹
sudo useradd redis
sudo mkdir -p /var/lib/redis
sudo mkdir -p /var/log/redis
sudo chown redis.redis /var/lib/redis ＃db文件放在这里，要修改redis.conf
sudo chown redis.redis /var/log/redis
3，配置init脚本
其实git上上很多老外写好的启动脚本，不过大部分都是ubuntu的，对于Centos，也有一份
https://gist.github.com/1335694
经过我的修改，如下：
###########################
PATH=/usr/local/bin:/sbin:/usr/bin:/bin
REDISPORT=6379
EXEC=/usr/local/bin/redis-server
REDIS_CLI=/usr/local/bin/redis-cli
PIDFILE=/var/run/redis.pid
CONF="/etc/redis.conf"
case "$1" in
start)
if [ -f $PIDFILE ]
then
echo "$PIDFILE exists, process is already running or crashed"
else
echo "Starting Redis server..."
$EXEC $CONF
fi
if [ "$?"="0" ]
then
echo "Redis is running..."
fi
;;
stop)
if [ ! -f $PIDFILE ]
then
echo "$PIDFILE does not exist, process is not running"
else
PID=$(cat $PIDFILE)
echo "Stopping ..."
$REDIS_CLI -p $REDISPORT SHUTDOWN
while [ -x ${PIDFILE} ]
do
echo "Waiting for Redis to shutdown ..."
sleep 1
done
echo "Redis stopped"
fi
;;
restart|force-reload)
${0} stop
${0} start
;;
*)
echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2
exit 1
esac
##############################
把上述代码存为redis,放到/etc/init.d/下面
chown +x ／etc/init.d/redis
其实做成服务启动，也是调用redis-server，如果想让它在后台作为daemon运行，那么
需要修改redis.conf,将 daemonize yes 改为 daemonize no
4，设定开机启动服务sudo chkconfig redis on
5，启动,停止redis启动：
service redis start 或者 ／etc/init.d/redis start
停止：
service redis stop 或者 ／etc/init.d/redis stop
6，测试redisredis-cli
redis 127.0.0.1:6379> set foo 123
OK
redis 127.0.0.1:6379> get foo
"123"
redis 127.0.0.1:6379> exit
