redis config

config from command line

You can also add options from command line. Just add -- before the keyword.

$ ./redis-server  --port 6000

online config

Some configs support online update. You can use config get xxx to get it and use config set xxx to set it. Attention, this doesn't update the redis.conf file so it won't take effect after restart.

config overwrite

You can set same config for multiple times. However, only the last one will take effect. It's easy to understand for simple config like port, timeout. However, for save, it allows multiple line config like

save 900 1               # save if there has at least 1 key changed in 900 seconds
save 60 10000            # save if there has at least 10000 keys changed in 60 seconds

The save 60 10000 won't overwrite the previous save 900 1. All of the save will take effect. Then how to overwrite it?

You can just add a line save "" and it means that all previous save were discarded.

save ""                  # discard all previous save
save 60 3000             # new settings
save 300 10
