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 
/usr/local/bin/redis-server /home/sysusr/redis/redis-cluster/redis-20000.conf 
/usr/local/bin/redis-server /home/sysusr/redis/redis-cluster/redis-20001.conf

/usr/local/bin/redis-server /home/sysusr/redis/redis-cluster/redis-20005.conf 
/usr/local/bin/redis-cli -a 123456 --cluster create --cluster-replicas 1 127.0.0.1:20000 127.0.0.1:20001 127.0.0.1:20002 127.0.0.1:20003 127.0.0.1:20004 127.0.0.1:20005
