Redis 4.x Cookbook

How to do it...

The configurations for deploying Redis on Linux are as follows:

1. Set the following memory-related kernel parameters:

~$ sudo sysctl -w vm.overcommit_memory=1
~$ sudo sysctl -w vm.swappiness=0

To persist these parameters add the following:

echo vm.overcommit_memory=1" >> /etc/sysctl.confecho "vm.swappiness=0" >> /etc/sysctl.conf

To check if these parameters have been set, add the following:

~$ sudo sysctl vm.overcommit_memory vm.swappiness 
vm.overcommit_memory = 1 
vm.swappiness = 0  

2. Moreover, disable the transparent huge page feature:

~$ sudo su - 
~# echo never > /sys/kernel/mm/transparent_hugepage/enabled 
~$ echo never > /sys/kernel/mm/transparent_hugepage/defrag 

To persist these settings, add the following:
