[Redis] [redis-db] Installing Redis Sentinel As Windows Service

Hi Rushdeep,

Everything other than the *--service-install* and -*-service-name*
arguments are passed to the instance of Redis that is launched as a
service. You could use the following command line to install a sentinel
instance as a service:

     *redis-server --service-install --service-name Sentinel1
sentinel.1.conf --sentinel*

In this case the arguments passed to the service instance will be "*sentinel.1.conf
--sentinel*".

Hi Jonathan,

                I am using MSOPENTECH Redis with 1 master and 2 slaves on
windows 2012 server machines. On each machine I run redis-server.exe as
Windows service as Redis server and as sentinel. if there is problem with
master I can see one of the slave being promoted as master. Any idea how my
application will come to know of this switch over? I am using
Servicestack.redis c# client api. Previously I was using solution mentioned
on this link
<<http://www.codedisqus.com/CJVkUPeVgU/getting-redis-master-address-from-sentinel-c.html>>
but it has stopped working. Any code sample would be helpful.

I'm new to Redis, I'm trying configure Redis environment for
high-availablity as below,

Machine 1 : Redis Master & a Sentinel (monitoring Redis master)
Machine 2 : Redis Slave & a Sentinel (monitoring Redis master)
Machine 3 : Redis Slave & a Sentinel (monitoring Redis master)

From application client (StackExchange.Redis), I'm able to connect Redis
Master with below config

<redisCacheClient allowAdmin="true" ssl="false" connectTimeout="5000"
database="0">
<hosts>
<add host="<Machine 1_IP>" cachePort="6379" />
</hosts>

Now, When my Machine 1 goes down, Sentinels switches the master to either
Machine 2 or Machine 3.

1. How will my Application client know that Redis master has been switched?
2. Should I provide all Redis-server IP in Application client's app.config
section?

Please advise.

Thanks.

Hello Jonathan,

I tried the above command mentioned by you:


*redis-server --service-install --service-name Sentinel1 sentinel.1.conf
--sentinel*Though, it keeps on throwing error: "Invalid argument during
startup: unknown conf file parameter :"

Not sure what needs to be done to install Sentinel for Windows Redis. and
the essential settings to be kept under sentinel.1.conf. Could you please
elaborate on the same.

Thanks,
