linux redis-cluster ipv6方式

配置文件，具体字段的含义，可以参考其他文档。

1.单个文件的配置信息 redis_36380.conf

requirepass Paas_2024

port 36380

tcp-backlog 511

timeout 0

tcp-keepalive 300

daemonize yes

supervised no

pidfile /data/paas/apps/aicache-redis/redis_36380.pid

loglevel notice

logfile "/data/paas/apps/aicache-redis/logs/redis36380.log"

databases 16


dbfilename dump.rdb

dir /data/paas/apps/aicache-redis/data


appendonly no

appendfilename "appendonly36380.aof"

appendfsync everysec


cluster-enabled yes
cluster-config-file nodes36380.conf
cluster-node-timeout 20000
cluster-announce-ip 2409:806a:5af0:2000::f8ac
cluster-announce-port 36380
cluster-announce-bus-port 46380
masterauth Paas_2024

这会看配置，才发现，timeout的值设置错了，想设置成20000的，结果，设置为了0。

2.其余配置文件

将redis_36380.conf 复制6份，将对应端口都sed修改成对应的端口。

redis_36380.conf -->ip1/ redis_36381.conf

redis_36380.conf --> ip2/redis_36380.conf

redis_36380.conf --> ip2/redis_36381.conf

redis_36380.conf --> ip3/redis_36380.conf

redis_36380.conf --> ip3/redis_36381.conf

3.各个redis都要启动

cat start_redis.sh
cd /data/paas/apps/aicache-redis; bin/redis-server redis_36380.conf
echo "36380 start done"

cd /data/paas/apps/aicache-redis36381; bin/redis-server redis_36381.conf
echo "36381 start done"

4.集群启动
