分配槽位

node1分配：0~5461
node2分配：5462~10922
node3分配：10923~16383

分配脚本addslots.sh

#!/bin/bash
REDIS_CLI=`which redis-cli`
REDIS_PASS=''

#node1
n=0
for ((i=n;i<=5461;i++))
do
   $REDIS-CLI -h 192.168.1.144 -p 6000 -a $REDIS_PASS CLUSTER ADDSLOTS $i
done

#node2
n=5462
for ((i=n;i<=10922;i++))
do
   $REDIS-CLI -h 192.168.1.144 -p 6001 -a $REDIS_PASS CLUSTER ADDSLOTS $i
done

#node3
#!/bin/bash
n=10923
for ((i=n;i<=16383;i++))
do
   $REDIS-CLI -h 192.168.1.144 -p 6002 -a $REDIS_PASS CLUSTER ADDSLOTS $i
done

redis集群动态添加密码

config rewrite 写入配置

for i in {6000..6002}; do echo $i;done

for i in {6000..6002};  do echo $i; redis-cli -c -h 192.168.1.144 -p $i config set requirepass abcdefg ;done
