How to start redis-server on a different port than the default port 6379 in ubuntu

Question

How to start redis-server on a different port than the default port 6379 in Ubuntu? I have used the following steps to install the redis:

Answer 1

1. Locate your redis.conf file (it will probably be at /etc/redis/6379.conf).
2. Copy the file or edit that one and change the port directive to any free port.
3. Start Redis with the new config file (note that if you've copied the file in the previous step, you'll need to change the service's startup script to use that file).
