1、关闭cluster全部节点
2、删除所有nodes.conf文件
3、开启全部节点
4、依次flushall
5、重建集群即可

Redis3配置Cluster
1、redis3的cluster是基于ruby的，所以要安装好ruby，然后安装redis的gem
gem install redis
2、然后配置6份redis，修改配置如下
| 节点 | ||||||
| dbm6379 | dbm6380 | dbm6381 | dbs6382 | dbm6383 | dbm6384 | |
| 配置文件 | dbm6379/conf/redis.conf | dbm6380/conf/redis.conf | dbm6381/conf/redis.conf | dbs6382/conf/redis.conf | dbm6383/conf/redis.conf | dbm6384/conf/redis.conf |
| port | 6379 | 6380 | 6381 | 6382 | 6383 | 6384 |
| logfile | “/home/neohope/DB/redis-3.0.4/cluster/dbm6379/logs/redis_log.log” | “/home/neohope/DB/redis-3.0.4/cluster/dbm6380/logs/redis_log.log” | “/home/neohope/DB/redis-3.0.4/cluster/dbm6381/logs/redis_log.log” | “/home/neohope/DB/redis-3.0.4/cluster/dbm6382/logs/redis_log.log” | “/home/neohope/DB/redis-3.0.4/cluster/dbm6383/logs/redis_log.log” | “/home/neohope/DB/redis-3.0.4/cluster/dbm6384/logs/redis_log.log” |
| dir | “/home/neohope/DB/redis-3.0.4/cluster/dbm6379/data” | “/home/neohope/DB/redis-3.0.4/cluster/dbm6380/data” | “/home/neohope/DB/redis-3.0.4/cluster/dbm6381/data” | “/home/neohope/DB/redis-3.0.4/cluster/dbm6382/data” | “/home/neohope/DB/redis-3.0.4/cluster/dbm6383/data” | “/home/neohope/DB/redis-3.0.4/cluster/dbm6384/data” |
| cluster-enabled | yes | yes | yes | yes | yes | yes |
| cluster-config-file | nodes-6379.conf | nodes-6380.conf | nodes-6381.conf | nodes-6382.conf | nodes-6383.conf | nodes-6384.conf |
| cluster-node-timeout | 15000 | 15000 | 15000 | 15000 | 15000 | 15000 |
| cluster-migration-barrier | 1 | 1 | 1 | 1 | 1 | 1 |
| cluster-require-full-coverage | yes | yes | yes | yes | yes | yes |
3、启动redis
#!/bin/sh ~/DB/redis-3.0.4/bin/redis-server ~/DB/redis-3.0.4/cluster/dbm6379/conf/redis.conf & echo $! & ~/DB/redis-3.0.4/bin/redis-server ~/DB/redis-3.0.4/cluster/dbm6380/conf/redis.conf & echo $! & ~/DB/redis-3.0.4/bin/redis-server ~/DB/redis-3.0.4/cluster/dbm6381/conf/redis.conf & echo $! & ~/DB/redis-3.0.4/bin/redis-server ~/DB/redis-3.0.4/cluster/dbs6382/conf/redis.conf & echo $! & ~/DB/redis-3.0.4/bin/redis-server ~/DB/redis-3.0.4/cluster/dbs6383/conf/redis.conf & echo $! & ~/DB/redis-3.0.4/bin/redis-server ~/DB/redis-3.0.4/cluster/dbs6384/conf/redis.conf & echo $!
4、配置cluster
#!/bin/sh #这里最好不要用127.0.0.1做地址 ~/DB/redis-3.0.4/bin/redis-trib.rb create --replicas 1 127.0.0.1:6379 127.0.0.1:6380 127.0.0.1:6381 127.0.0.1:6382 127.0.0.1:6383 127.0.0.1:6384
5、测试redis cluster
~/DB/redis-3.0.4/bin/redis-cli -c -p 6379 set key01 a set key02 b set key03 c set key04 d dbsize keys * get key03
6、关闭redis
#!/bin/sh ~/DB/redis-3.0.4/bin/redis-cli -p 6379 shutdown ~/DB/redis-3.0.4/bin/redis-cli -p 6380 shutdown ~/DB/redis-3.0.4/bin/redis-cli -p 6381 shutdown ~/DB/redis-3.0.4/bin/redis-cli -p 6382 shutdown ~/DB/redis-3.0.4/bin/redis-cli -p 6383 shutdown ~/DB/redis-3.0.4/bin/redis-cli -p 6384 shutdown
Redis主从数据库（Shell）
1、基本配置如下
| 数据库 | master | slave01 | slave02 |
| 配置文件 | redis.master.conf | redis.slave01.conf | redis.slave02.conf |
| ip地址 | localhost | localhost | localhost |
| 端口 | 6379 | 6380 | 6381 |
| logfile | “D:/Database/Redis2.8/mirror/master/logs/redis_log.txt” | “D:/Database/Redis2.8/mirror/slave01/logs/redis_log.txt” | “D:/Database/Redis2.8/mirror/slave02/logs/redis_log.txt” |
| dir | “D:/Database/Redis2.8/mirror/master/data/” | “D:/Database/Redis2.8/mirror/slave01/data/” | “D:/Database/Redis2.8/mirror/slave02/data/” |
| slaveof | – | localhost 6379 | localhost 6379 |
| slave-serve-stale-data | – | yes | yes |
| slave-read-only | – | yes | yes |
| slave-priority | – | 100 | 100 |
| maxheap | – | 1073741824 | 1073741824 |
| heapdir | – | D:\Database\Redis2.8\mirror\slave01\heap | D:\Database\Redis2.8\mirror\slave02\heap |
2、启动
redis-server.exe D:\Database\Redis2.8\mirror\redis.master.conf redis-server.exe D:\Database\Redis2.8\mirror\redis.slave01.conf redis-server.exe D:\Database\Redis2.8\mirror\redis.slave02.conf
3、测试
D:\Database\Redis2.8>redis-cli 127.0.0.1:6379> dbsize (integer) 0 127.0.0.1:6379> set key01 a OK 127.0.0.1:6379> exit D:\Database\Redis2.8>redis-cli -p 6380 127.0.0.1:6380> get key01 "a" 127.0.0.1:6380> set key02 b (error) READONLY You can't write against a read only slave. 127.0.0.1:6380> exit D:\Database\Redis2.8>redis-cli -p 6381 127.0.0.1:6381> get key01 "a" 127.0.0.1:6381> set key02 b (error) READONLY You can't write against a read only slave. 127.0.0.1:6381> exit
4、关闭
redis-cli -p 6380 shutdown redis-cli -p 6381 shutdown redis-cli -p 6379 shutdown
