目录
1、IP、端口分配
环境：centos7.0 redis6.0.8
一台虚拟机创建6个节点
127.0.0.1 1001 1002 1003 1004 1005 1006
2、创建相关文件夹
# mkdir /usr/local/redis/cluster
# mkdir /usr/local/redis/cluster/100{1,2,3,4,5,6}
# mkdir /usr/local/redis/cluster/100{1,2,3,4,5,6}/data
3、添加配置文件
vi /usr/local/redis/cluster/1001/redis.conf
daemonize yes
pidfile "/usr/local/redis/cluster/redis_1001.pid"
port 1001
bind 0.0.0.0
protected-mode no
tcp-backlog 511
timeout 0
tcp-keepalive 60
loglevel notice
logfile "/usr/local/redis/cluster/1001/redis_1001.log"
dir ""/usr/local/redis/cluster/1001/data"
databases 16
save 900 1
save 300 10
save 60 10000
stop-writes-on-bgsave-error yes
rdbcompression yes
rdbchecksum yes
dbfilename dump-master.rdb
masterauth 123
slave-serve-stale-data yes
slave-read-only yes
repl-disable-tcp-nodelay no
slave-priority 100
requirepass 123
maxmemory 3gb
maxmemory-policy volatile-lru
appendonly no
appendfilename "appendonly.aof"
appendfsync everysec
no-appendfsync-on-rewrite yes
auto-aof-rewrite-percentage 100
auto-aof-rewrite-min-size 64mb
aof-load-truncated yes
lua-time-limit 5000
slowlog-log-slower-than 10000
slowlog-max-len 128
latency-monitor-threshold 0
notify-keyspace-events ""
hash-max-ziplist-entries 512
hash-max-ziplist-value 64
list-max-ziplist-entries 512
list-max-ziplist-value 64
set-max-intset-entries 512
zset-max-ziplist-entries 128
zset-max-ziplist-value 64
hll-sparse-max-bytes 3000
activerehashing yes
client-output-buffer-limit normal 0 0 0
client-output-buffer-limit slave 256mb 64mb 60
client-output-buffer-limit pubsub 32mb 8mb 60
hz 10
aof-rewrite-incremental-fsync yes
cluster-enabled yes
cluster-config-file nodes-1001.conf
cluster-node-timeout 15000
requirepass 123
1002 1003 1004 1005 1006文件夹中同样添加，注意修改其中的端口号等数据。
4、启动节点
# /usr/local/redis/src/redis-server /usr/local/redis/cluster/1001/redis.conf
6个节点均启动
5、创建集群
# ./redis-cli --cluster create 127.0.0.1:1001 127.0.0.1:1002 127.0.0.1:1003 127.0.0.1:1004 127.0.0.1:1005 127.0.0.1:1006 --cluster-replicas 1 -a 123
cluster-replicas 1 代表一个master后有几个slave节点。-a 代表连接密码
6、验证
查看主从配对情况
# ./redis-cli -c -p 1001 -a 123
查看集群情况
> cluster nodes
kill 掉1001 ，发现其从节点1004转为了master。重新启动1001，其变成slave节点。
主节点故障后，下挂从节点会升级成主节点，并接替主节点的槽位。旧主节点上线后，也只能作为其从节点。
