• 安装
  在Redis官网 (https://redis.io/download) 下载最新的稳定版本
  wget http://download.redis.io/releases/redis-3.2.6.tar.gz
tar xzf redis-3.2.6.tar.gz
cd redis-3.2.6
make

• 配置Redis
  打开redis-3.2.6文件夹下redis.conf，修改如下：
  daemonize no 改为 daemonize yes
  logfile "" 改为 logfile "/var/log/redis/redis.log"

• 设置开机启动
  在/etc/init.d/文件夹下创建一个redis文件，输入以下：

#!/bin/sh
#Configurations injected by install_server below....

EXEC=/tmp/redis-3.2.6/src/redis-server   # redis-server的路径
CLIEXEC=/tmp/redis-3.2.6/src/redis-cli   # redis-cli的路径
PIDFILE=/var/run/redis_6379.pid  # redis.conf里有这个参数，将其复制过来
CONF="/tmp/redis-3.2.6/redis.conf"  # redis.conf的路径
REDISPORT="6379"  # 端口

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
        ;;
    stop)
        if [ ! -f $PIDFILE ]
        then
            echo "$PIDFILE does not exist, process is not running"
        else
            PID=$(cat $PIDFILE)
            echo "Stopping ..."
            $CLIEXEC -p $REDISPORT shutdown
            while [ -x /proc/${PID} ]
            do
                echo "Waiting for Redis to shutdown ..."
                sleep 1
            done
            echo "Redis stopped"
        fi
        ;;
    status)
        PID=$(cat $PIDFILE)
        if [ ! -x /proc/${PID} ]
        then
            echo 'Redis is not running'
        else
            echo "Redis is running ($PID)"
        fi
        ;;
    restart)
        $0 stop
        $0 start
        ;;
    *)
        echo "Please use start, stop, restart or status as first argument"
        ;;
esac

然后将改文件改为可执行
chmod +x redis
将该执行文件加入开机启动
update-rc.d redis defaults

• 启动redis
  /etc/init.d/redis start
