1、redis.io 上下载 redis安装包（我下载的是2.8稳定版，3.0版本增加了数据库集群） https://github.com/antirez/redis/archive/2.8.23.tar.gz

2、解压

tar xzf 2.8.23.tar.gzcd redis-2.8.23make

3、添加redis用户

useradd redis  mkdir -p /var/lib/redis  mkdir -p /var/log/redis  chown redis.redis /var/lib/redis  #后文用到的数据存放地址chown redis.redis /var/log/redi  #后文用到的日志存放地址

4、设置开机启动项

将redis的配置文件复制到 /etc目录中

cp redis.conf /etc

设置redis.conf文件

设置数据存放路径：dir /var/lib/redis #默认为./

设置日志存放路径：logfile "/var/log/redis/redis.log" #默认为空

设置redis后台启动：daemonize yes #默认为no

设置init启动脚本

#!bin/sh# chkconfig: 2345 10 90  # description: Start and Stop redis  PATH=/usr/local/bin:/sbin:/usr/bin:/binREDISPORT=6379EXEC=/usr/local/bin/redis-serverREDIS_CLI=/usr/local/bin/redis-cliPIDFILE=/var/run/redis.pidCONF="/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 1esac

将启动脚本复制到 /etc/init.d/中

设置可执行权限
chmod +x /etc/init.d/redis

设置开机启动服务

chkconfig redis on

redis启动命令：service redis start

redis停止命令： service redis stop
