redis集群宕机后重启的示例：
centos下的redis无数据启动和持久化重启脚本：
1.redis_clear_restart.sh，代码:
for p in `ps -ef|grep /usr/local/bin/redis-server | awk '{print $2"_"$3}'`
do
a=`echo $p |awk -F _ '{print $1}'`
b=`echo $p |awk -F _ '{print $2}'`
if [ $b == "1" ]; then
echo "kill -9 $a `kill -9 $a` "
fi
done
echo "rm -rf appendonly_*.aof dump_*.rdb nodes-2000*.conf"
rm -rf appendonly_*.aof dump_*.rdb nodes-2000*.conf
