Redis master slave setup in single server

[rudr...@gmail.com]

Hi 

I would like to bring up the  Redis-DB in Master Slave mode.

Is it possible to run both master and slave in single system?

Can somebody give me some information on the same.

Thanks,

Rudra

You can run multiple instances on a single server.
Just make sure each instance listens on a different port.

Your two Redis-server processes must use different PID files and different working directories, must listen for connections on different TCP ports, and one of them (the slave) will most likely have a 'slaveof' parameter in its config file.  The pid file location is the 'pidfile' parameter, the working directory is the 'dir' parameter, and the TCP port is the 'port' parameter in the config file.

This means your two processes must have have different config files.  Different config files on Linux/Unix servers means a different command to launch the processes (the config file is specified as an argument to the command that invokes redis-server), so you need two start scripts or systemd config files.

I have no experience with Windows server, so I don't know how to do it on Windows (or even if it's possible).

Hi Rudra,

You can setup both the master and slave in single server by running the instances on different ports and having different pidfiles.

However, I would recommend having them on different server to guarantee availability of data if a machine goes down.
