我的/etc/init.d/redis 脚本可以正常启动或者停止redis服务

service redis start
service redis stop
service redis restart

我也设置了/etc/init.d/redis权限为755
也设置了开机启动chkconfig redis on

chkconfig --list如下：

redis              0:关    1:关    2:开    3:开    4:开    5:开    6:关

请问为什么不能开机启动呢？求解决办法

附：/etc/init.d/redis代码如下：

# chkconfig: 2345 10 90
#!/bin/sh
#
# Simple Redis init.d script conceived to work on Linux systems
# as it does use of the /proc filesystem.

        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 -a $AUTH shutdown
                while [ -x /proc/${PID} ]
                do
                    echo "Waiting for Redis to shutdown ..."
                    sleep 1
                done
                echo "Redis stopped"
        fi

        ${0} start
