redis sentinel配置（windows环境）

redis sentinel配置（windows环境）

环境介绍

1.操作系统windows7
2.redis版本3.2

安装redis

1.redis官方暂不支持windows版本，所以需要在github下载。

https://github.com/MicrosoftArchive/redis/releases[/code] 
2.解压至本地。


集群配置
master ip:127.0.0.1 port:6379
slave1 ip:127.0.0.1 port:6380
slave2 ip:127.0.0.1 port:6381
sentinel1 ip:127.0.0.1 port:16379
sentinel2 ip:127.0.0.1 port:16380
sentinel3 ip:127.0.0.1 port:16381


修改配置文件
1.复制并新建三份redis.conf文件，分别命名为redis6379.conf、redis6380.conf、redis6381.conf。
其中，redis6379.conf为master的conf，redis6380.conf和redis6381.conf为slave1和slave2的conf。


2.redis6379.conf配置信息如下：
bind 127.0.0.1

protected-mode no

port 6379

tcp-backlog 511

timeout 0

tcp-keepalive 0

loglevel notice

logfile “”

databases 16

save 900 1

save 300 10

save 60 10000

stop-writes-on-bgsave-error yes

rdbcompression yes

rdbchecksum yes

dbfilename dump.rdb

dir ./redis-6379

masterauth 15144

slave-serve-stale-data yes

slave-read-only yes

repl-diskless-sync no

repl-diskless-sync-delay 5

repl-disable-tcp-nodelay no

repl-backlog-size 1mb

slave-priority 100

requirepass 15144

appendonly yes

appendfilename “appendonly.aof”

appendfsync everysec

no-appendfsync-on-rewrite no

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-size -2

list-compress-depth 0

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

redis.conf各配置项具体作用可参照redis.conf原文件的注释。
3.redis6380.conf和redis6381.conf的配置信息大部分与redis6379.conf相同，需改动配置项如下：
redis6380.conf

bind 127.0.0.1

slaveof 127.0.0.1 6379

port 6380

dir ./redis-6380

redis6381.conf

bind 127.0.0.1

slaveof 127.0.0.1 6379

port 6381

dir ./redis-6381

4.新建三份 sentinel.conf 配置文件，分别命名为sentinel16379.conf、sentinel16380.conf、sentinel16381.conf。配置信息如下：
port 16379
sentinel monitor mymaster 127.0.0.1 6379 2
sentinel down-after-milliseconds mymaster 5000
sentinel parallel-syncs mymaster 1
sentinel failover-timeout mymaster 15000
sentinel auth-pass mymaster 15144


除端口号外，其他信息一样。
5.启动master、slave1、slave2、sentinel。
启动命令如下：
redis-server.exe redis6379.conf
redis-server.exe redis6380.conf
redis-server.exe redis6381.conf
redis-server.exe sentinel16379.conf --sentinel
redis-server.exe sentinel16380.conf --sentinel
redis-server.exe sentinel16381.conf --sentinel


启动成功界面如下：
master：


slave1：


slave2：与slave1基本相同
sentinel：


5.查看redis服务器状态
master：


slave1：


slave2：与slave1基本相同
sentinel：


6.测试
a.关闭master
b.查看其他服务器状态




c.查看sentinel信息，master切换成功



7.搭建过程中遇到的问题
a.第一次启动slave服务的时候，遇到如下问题：




[7256] 06 Dec 11:38:05.158 * Background append only file rewriting started by pi
d 10344
[7256] 06 Dec 11:38:05.232 * AOF rewrite child asks to stop sending diffs.

[7256] 06 Dec 11:38:06.733 # Background AOF rewrite terminated with error


网上找了一些资料，自己尝试了一些方法，最后通过更改redis6379.conf、redis6380.conf、redis6381.conf三个配置文件中的 dir 配置项来解决，dir配置的文件地址不能一样。应该是master和slave的dir配置项如果一样的话，slave和master同步的时候异常了。


b.启动sentinel服务后，查看sentinel信息，发现master status=sdown，slaves=0。




但是在master服务上显示两个slave已经连接成功了。




原因是因为master和slave设置了验证密码，但是sentinel的配置里面没有设置sentinel auth-pass mymaster 15144，在sentinel.conf里面添加一下就好了。
