Redis service failed to start

[Kevin Burton]

I am working with a Windows Redis server. I issue the following commands:

.\redis-server.exe --service-install --service-name master .\redis.conf

.\redis-server.exe --service-start --service-name master

And they execute just fine. However when I want to start the slave with similar commands:

.\redis-server.exe --service-install --service-name slave .\redis.conf

.\redis-server.exe --service-start --service-name slave

I get an error that the "Redis service failed to start". I tried just running

.\redis-server.exe .\redis.conf

so the output comes to the screen and there doesn't seem to be a problem:

So why is the service version of the slave failing?

Ideas?

Thank you.

Given that you're running two redis instances with the same config, you're
probably trying to listen on the same port, which is going to cause
problems. Try having two different config files, with different ports.

Also, you may wish to ask on a Windows-specific Redis list (if there is
one), about how to get access to whatever logging is available on Windows.
That may give you more specific information about what is *actually* wrong
when the slave runs as a service.

The file name is the same but the invocation is in different folders/directories. It is different ports. Like I said when started not as a service everything seems to be OK. I have included the output on a earlier thread

I suspect that you are hitting #181

This has been fixed in recent releases, though they haven't been published to nuget/chocolatey yet. Could you try https://github.com/MSOpenTech/redis/releases/tag/win-2.8.17.3 ? You'll have to download the .zip file and extract the binaries.

Thanks,

Thank you. I have taken a great leap forward. But, I am now stuck on starting up the sentinel. I get the error:

[4284] 22 Jan 09:26:06.552 # Sentinel runid is 532fc6ab06aae3c18ca088bf02161d060

1ec9361

[4284] 22 Jan 09:26:06.552 # Sentinel config file C:\Projects\RedisTest\RedisSer

ver\sentinel1/C:\Projects\RedisTest\RedisServer\sentinel1\redis.conf is not writ

able: Invalid argument. Exiting...

I install the sentinel service as

>.\redis-server.exe --service-install --service-name sentinel1 C:\Projects\RedisTest\RedisServer\sentinel1\redis.conf --sentinel

It is almost like I shouldn't put the full path to the configuration file?

You need to invoke the service installation command from the same directory as redis-server.exe, and pass the config file as a relative path. This is a known limitation, and on my list of things to fix.

[Kevin Burton]

Not just for sentinel but master and slave services also?

[Alexis Campailla]

1) Absolute config paths work for masters/slaves but not for sentinel.

2) If you pass the config file as a relative path, it will be relative to the current directory when you run the –service-install command, but when the service is started, the current directory is set to the directory where redis-server.exe resides. If those two directories are not the same, the service won't start.

So for masters/slaves you should be able to use absolute config paths.

[Kevin Burton]

Thank you that is what I found.
