# 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

### 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

rdbchecksum yes  
dbfilename dump.rdb  
dir ./redis-6379  
masterauth 15144  
slave-serve-stale-data yes  
slave-read-only yes  
repl-diskless-sync no

### 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： ####

![这里写图片描述][SouthEast 1]

#### slave1： ####

![这里写图片描述][SouthEast 2]

#### slave2：与slave1基本相同 ####

#### sentinel： ####

![这里写图片描述][SouthEast 3]

### 5.查看redis服务器状态 ###

#### master： ####

![这里写图片描述][SouthEast 4]

#### slave1： ####

![这里写图片描述][SouthEast 5]

#### slave2：与slave1基本相同 ####

#### sentinel： ####

![这里写图片描述][SouthEast 6]

### 6.测试 ###

a.关闭master
    b.查看其他服务器状态

![这里写图片描述][SouthEast 7]  
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：

![这里写图片描述][SouthEast 9]

[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 11:38:05.332 # fork operation complete

[7728] 06 Dec 11:38:06.724 # Error moving temp append only file on the final des tination: Input/output error [7728] 06 Dec 11:38:06.724 # rewriteAppendOnlyFile failed in qfork: Input/output error [7256] 06 Dec 11:38:06.733 # fork operation complete [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。

![这里写图片描述][SouthEast 10]

但是在master服务上显示两个slave已经连接成功了。

![这里写图片描述][SouthEast 11]

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。
