1.redis.conf

　　a.daemonize yes

　　b.pidfile /var/run/xxx.pid

2./etc/init.d/redis

//加了下面三个注释部分，才支持设置开机自启动

#!/bin/sh
# chkconfig: 2345 90 10

下载

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

新建用户。数据和日志文件夹

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

脚本设置

见上面

设置权限

chmod +x /etc/init.d/redis

设置自动启动:

sudo chkconfig redis on

启动或者关闭服务

service redis start #或者 /etc/init.d/redis start
service redis stop #或者 /etc/init.d/redis stop

测试是否成功

　　　　　1。reboot

　　　　　2. redis-cli

　　　　　3.get xxxx
