redis集群宕机后怎么重启

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-20004.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 <F

yes
