redis集群宿主机故障forget故障节点

cat ./redis_cluster_forget_node.sh

#echo "usage: host port"
nodes_addrs=$(redis-cli -h $1 -p $2 -a password  cluster nodes|grep -v handshake| awk '{print $2}')
echo $nodes_addrs
for addr in ${nodes_addrs[@]}; do
    host=${addr%:*}
    port=${addr#*:}
    del_nodeids=$(redis-cli -h $host -p $port -a  password cluster nodes|grep -E 'handshake|fail'| awk '{print $1}')
    for nodeid in ${del_nodeids[@]}; do
        echo $host $port $nodeid
        redis-cli -h $host -p $port -a  password cluster forget $nodeid
    done
done

#password 替换为具体集群密码
#执行参数 为任意一个可用节点  端口 ip

#执行脚本，通知所有集群主节点 遗忘（forget）故障、无法修复节点
sh ./redis_cluster_forget_node.sh 127.0.0.1 6379  

#执行成功后，在补齐节点、均衡节点等
