Java开发环境系列：Redis进阶之集群哨兵及主从复制

搭建master

修改redis配置redis.windows.conf：

• 修改监听端口：port 26379
• 修改绑定IP：bind 127.0.0.1
• 添加redis日志：logfile "..\\logsdata\\redis.master.26379.log.txt"
• 添加Redis数据库：databases 16
• 数据库磁盘影像: dbfilename dump.master.26379.rdb
• 数据存储的位置：dir ..\\redisdata
• 磁盘数据持久化：appendfilename "appendonly.master.26379.aof"

搭建salve

修改redis配置redis.windows.conf：

• 修改监听端口：port 26380
• 修改绑定IP： bind 127.0.0.1
• 添加redis日志：logfile "..\\logsdata\\redis.slave.26380.log.txt"
• 添加Redis数据库：databases 16
• 数据库磁盘影像: dbfilename dump.slave.26380.rdb
• 数据存储的位置：..\\redisdata
• 主从配置：slaveof 127.0.0.1  26379
• 磁盘数据持久化：appendfilename "appendonly.slave.26380.aof"

常用命令

进入主redis:  Redis-x64-3.2.100-master\redis-cli -h 127.0.0.1 -p 26379

查看所有   keys *

查看某类   keys *session*

清空所有   flushall

测试集群效果 在master上新增set name 'wangxinagyu'，在slave上可以查看到get name（主从复制）

D:\DevTools\redis\Redis-x64-3.2.100-master>redis-cli -h 127.0.0.1 -p 26379

127.0.0.1:26379> keys *

1) "yuanqin_hash"

2) "yuanqin"

3) "yuanqin_set"

4) "yuanqin_list"

5) "yuanqin_zset"

127.0.0.1:26379> set name 'wangxinagyu'

OK

D:\DevTools\redis\Redis-x64-3.2.100-slave>redis-cli -h 127.0.0.1 -p 26380

127.0.0.1:26380> get name

"wangxiangyu"

集群模式哨兵操作（Redis的setntinel操作命令）：

sentinel masters 

sentinel slaves etreasury 

sentinel get-master-addr-by-name eteasury 

ping

备注

附件解压之后，上述涉及IP（127.0.0.1）的地方直接改成本机IP即可以使用。
