Running multiple Redis instances on the same server

Redis runs as a background process that listens to a specific port (6379 by default) for incoming requests from clients. Running multiple instances requires a separate conf file and a new init script. The conf file specifies details for the new instance, and the init script handles starting/stopping of the instance background process.

Make a copy of the redis.conf file at C:\Program Files\Redis\Conf and give it a new name redis-s1.conf. Leave both files in the same directory C:\Program Files\Redis\Conf

Open the redis-s1.conf with your favorite text editor (e.g. notepad ) and change the following:

PID File

  • pidfile /var/run/redis-s1.pid

Port

  • port 6380

Log File

  • logfile “C:/Program Files/Redis/logs/redis-s1.log

Data Directory (don’t forget to create that directory)

  • dir “C:/Program Files/Redis/data2”

For replication only : If you planning to use this instance as a slave in master-slave replication setting (where 127.0.0.1 is the master instance IP, 6379 in the master instance port)

  • slaveof 127.0.0.1 6379

To start the new instance

  1. Open a new command window
  2. Navigate to C:\Program Files\Redis
  3. Run redis-server conf\redis-s1.conf

To connect to the new instance

  1. Open a new command window
  2. Navigate to C:\Program Files\Redis
  3. Run redis-cli –h 127.0.0.1 –p 6380

Now you can have multiple Redis instances on the same server like any other DBMS.
