What do these errors mean in Redis?

Question

linux

Hello everyone, please help a newbie solve a problem with Redis
I run the command redis-server
I get
# Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf
* Max number of open files set to 10032
# Opening port 6379: bind: Address already in use
How to solve these errors?
Thanks in advance

Well, that's exactly what he tells you.
He complains that you did not tell him which configuration file with server settings to use.
He says that since they did not say where to get the settings, he will use the default settings.
And after that, it finds that port 6379 is already occupied by something else (probably the same server that is already running).
To solve these errors, first tell us on what operating system do these manipulations occur?
